Why the U.S. thinks quarantining people coming in from China for 3 days is sufficient is beyond me. (At the time this was posted it was 3 days, and has now been increased to 14.)

Chinese residents are saying the crematoriums are running 24/7. For the amount of crematoriums they have burning non stop, it averages to about 100-200 deaths per day. And that's not including the people dying in their home unaccounted for after being barricaded in their own home by police/military

I had swine flu back in 2009 I thought I was going to die waking up in middle of the night couldn't breathe coughing up flem and mucus for a month even after I felt better.
I got H1N1. I literally could not get out of bed. Felt like I was going to die. That was about 10 years ago. Turned into pneumonia. My kids got it too. It went to pneumonia symptoms after the first two weeks in all of us. We did 1000mg of vitamin C every ten minutes the minute our lungs started making breathing difficult. Cleared it up in an hour. I have influenza A right now and it causes fatigue and a cough that is hard to shake. Still fatigued three weeks later.
@Etu Nimi I'll bet that's Pure fiction. Unless you are in possession of the gene sequence of both 2019-nCov AND this imaginary "patent" it's just assertion without evidence. RUclips videos are not evidence.
SARS was initially reported as 3-4% death rate and ended up being close to 10%. This is because the deaths of the current infected haven't happened yet.
Yes, they look at today’s infection numbers and calculate a death % of that but they should calculate it from the numbers of infected 2 weeks ago when today’s dead got infected, and then the numbers would be a lot higher as %. It’s going to change society , the economic shock will be incredible. China is the global factory. If goods don’t get made and people don’t move around the economies will go into freefall
Death rate may be higher since it takes days for people to die so I would think you would compare death rate with number of people infected a few days ago. What is more concerning is the 20% complication rate.
Al Katawazi agree. It’s the complication rate that concerns me the most. At one point it looked like 20% severe and 5% critical. It’s too soon to know what the actual figures but the spread rate is def concerning. Containment is the only way we can ‘win’ this battle.
That fact u need one of those special beds to take care of someone ”ebu” I think it's called that. Are limited and I think the United States has a majority filled?
@@josephpa05 Yes, there's not enough. And there's not enough quarantined beds from my understanding as well. It is "ICU". Not sure what they're going to do.
It could be higher due to the reasons you stated. But it could also be lower, since it's also possible that a lot of people who had it could have just thought they had a cold and didn't even go to the hospital and nobody outside of China has died yet.
Dr. Campbell you are an AMAZING teacher! I so appreciate how you teach and your patience in explaining technical terms, etc., so carefully and thoughtfully. You are a treasure. :) Thank you very much!!

I read this in an article: We have obtained biochemical and electron microscopic evidence of conformational changes at pH 8.0 and 37 degrees C in the coronavirus spike glycoprotein E2 (S). The importance of these changes is reflected in the loss of virus infectivity, the aggregation of virions, and increased virus-induced cell fusion at the same pH. Coronavirus (MHV-A59) infectivity is exquisitely sensitive to pH. (For example, your doctor may give you sodium bicarbonate (baking soda) to raise the pH of your blood.) So baking soda the cure?
It's those that already have lung damage and scar tissue. Their lungs aren't elastic and this kind of infection could pose a serious problem. Those that tend to get aspergillus as a result of pitted lungs from previous damage are also at risk of more serious outcomes and those that recently had lunch surgery and are on retroviral medicine to fight rejection. Lung patients are likely concerned as they're already high risk. We're not even yet talking about the HIV patients prone to an aggressive form of MAC. Asthmatics also and the elderly. It all depends on how hard your immune system can withstand the storm then launch an offensive. Intensive care will be overrun. So glad you're out here providing this info. Thank you sir.

In the Philippines, the first case of NCoV that was announced just yesterday is from a Chinese woman who came from Wuhan. She travelled to Hongkong and then the Philippines. By the time she arrived in the Philippines, the only symptom she had was mild cough and no fever. And it doesnt showed right away,it took days. Maybe that is the reason why she surpassed the thermal scanners in the airports.
Question - How can a Mortality Rate comparison be made between SARS and current NoroVirus. Looks.like the SARS rate was known only when the disease ended. Current NoroVirus has not ended. I think the mortality rate cannot be know at this point in time. I'm curious about that, just asking...
lets say the virus takes 1 week from reported infection to reported death, then youd have divide the total deaths now with the number of infected from 1week ago. that makes the fatality rate much, much higher at around *15-25 %*.
You have complete data of SARS to do a mortality rate. It takes a few days for confirmed patients to die, so a more accurate figure is take today’s death toll and compared that to the total number of confirmed cases a few days ago..
Confirmed cases vs. deaths isn't the mortality rate, cured cases vs. deaths is mortality rate. It's a 60% mortality rate right now according to the data available.
@Bill Whittaker the disease statistics are very odd right now, Hard to interpret anything without more data but it's tracking cured vs deaths at 60%, we will see a better picture as more data comes in.

Does the lack or lower severity of symptoms mean, that the body is capable of dealing with the infection and is there a probability, in which the body will not initiate an immune response at all?

This was the best education in regards to Coronavirus I’ve seen obviously delivered by a good doctor or a professor at a medical school level. Thank you sir for the post.
As of 30 Jan, good quality patient care may be keeping the present cohort of patients alive longer. As with SARS, it may turn out that deaths may occur after weeks or months. Survivors of SARS reported severe long-term fatigue symptoms were a major problem for some 40% of SARS patients, lasting years. If the disease were to spread rapidly, large numbers of those who are at present keeping patients alive might be worn out and debilitated or even infected and unable to perform their specialised tasks. The demand for oxygen, mechanical ventilation (and experts to operate it and nurse / treat the patients) would be overwhelmed. Spread of significant illnesses like this can threaten the functioning of a modern society in new ways. Without the small number of qualified skilled operators, who would run the power stations, water treatment plants etc? Just-in-time delivery systems would fail rapidly, as we rely on a small number of truck drivers to deliver huge quantities of food to shop shelves. A lot of fresh produce is stored not in warehouses but in the refrigerated trucks that are constantly on the road from distant farms. Without them, we would be in trouble. Even the fear of the illness on its own poses a risk for society, with the possibility of unrest and dissent. In any country with a repressive regime or with limited resources, there is a big risk of societal breakdown.
Great Videos. Just one question. When SARS started getting media attention I remember that the WHO first talked about a mortality rate of about 2-3% ultimately it turned out to be about 10% (and some regions had even higher rates). I looked it up and the mortality rate itself also followed an approximate bell curve pattern, starting with 1-2% and went up to 22% at its maximum and then went back down to 2%. Can you shed some light on this phenomenon?
It'll probably be because of how many people have it and when they got it, meaning severe symptoms occur at different points, so people merely haven't been infected long enough to have died yet, and then a surge may happen, and then it'll go down again idk though I'm not reliable I'm not a professional
You seem to have little knowledge of the subject. nCOV would appear to have a CFR of greater than 3%, the RO is in excess of 3, the SCR is circa 18% So if you extend the infection over time and the deaths over time graphs as more data becomes available. You will see a much steeper curve than for SARS. Do not make the mistake of comparing a finished cycle i.e. SARS directly to an early position nCOV The infection rate here is that of a pandemic. I am in Guangzhou and see at first hand. The best we can hope is no mutation before early stage vaccine.
These are are not assertions but are standard virology measurements based on the developing data set of the Wuhan Institute of Virology and could be provided by any first year student of virology.
Hello Dr. Campbell, I am wondering what the data of Total Deaths vs. Total Recovered means. Is the death rate measured as a ratio of Confirmed Cases or as a ratio of Recovered Cases? As of 4:00 PM GMT today 1/30/2020, there have been 171 deaths and 143 recoveries. Is this normal, or should we be seeing more recoveries than this? Is the death rate underestimated as a result? I am worried about underestimating the severity of this infection. Thanks.
14 day incubation, R naught around 2.6, mortality rate 2% and about four million people flying internationally every day. Asymptomatic transmission confirmed in Germany, Japan and I think Vietnam today. Any comments Dr. John?
I have a friend with a T-cell count of 250 (with diabetes), another with a count of 400. Are they likely to die if they contract nCoV? They live in NYC.
The death rate, you take todays deaths and go back 2 weeks for those infected at that time for the disease to take its course. Two weeks ago the infection rate was 1000 and todays deaths are 170, so about 17% death rate.
= @@Campbellteaching = My question is - Why can't they take blood samples from people that have recovered and give that to people who are sick, and then the sick people are getting the anti-bodies from the blood sample injection ??
Question about T cells - when someone runs a fever, aren't the T cells activated? For some reason I'm remembering T cells associated with viruses. And if you lower your temperature with drugs, the T cells are reduced, therefore giving a virus the upper hand. Am I remembering this correctly/incorrectly? Thank you!
Thanks for this amazing teaching about the disease. Unfortunately there are 9 suspect cases here in Brazil. Hopefully they'll not be confirmed. But I'm already searching for info about coronavirus.
While calculating MR we should take into account a lag between got infected and got dead. So we should divide number of ones who died today to number of ones who have infected by today minus x ( x= how many days it takes to die once being infected ). If you do this calculaltions you will see that MR is about 7% which is much much worse than SARS
@Roger Clemons MR of SARS wasn't 30%, you probably mixing up SARS with MERS. 90% of infected with SARS had very mild symptoms and recovered, but for the rest 10% MR was different for different groups,for those who were over 50, MR was close to 50%, for overs 5-15%. As for 2019-coV, we dont know for sure yet, we dont know the denominator: how many have been infected? Threre's probability, that most of infected have light symptoms and are not registered as infected, recover in few days. We are in the very beginning of the epidemy and dont have correct input data. My previous comment was about using wrong method. Not about exact numbers, which are going to be precise when this outbreak is over.

Hello, I am a high school student in Taiwan. As you may know, Taiwan is unfortunately invaded by the virus, yet due to political reasons, we are sadly excluded from the WHO meetings. We are on the first line of defending the the virus, if we do not receive the latest information, it will be exceedingly difficult for us to tackle the problem. To be honest, it is a quite terrible and horrifying time now. Whenever I watch the news, there are new cases daily. I hope we can all unite and overcome the virus. Stay safe and God bless
Really enjoying your videos and information. Thank you for your service to the public, people need to know these things in order to protect themselves. Even if ncov wasnt relevant right now i know i would still find your content fascinating as it is so well explained. Thank you and stay safe
Thank you for the videos John, thankfully in the UK (Northern Ireland for me) we haven’t seen this yet, though I suspect we will soon. I saw many asian students with face masks today, might stock up on a few incase it gets here. Very informative video once again!
Yes, that would make more sense. Everyone is calculating mortaility rate wrong. They divide number of deaths with number of infected but forget it's not something that was in the past and is over now (like SARS), it's ongoing and every day number of infected increases significantly. The correct way to calculate the mortality rate would be to divide current number of deaths with number of infected as it was N days ago. That would equal 15-20% which is more realistic than 2-3% seen all over the media.
@@____Neo I thought about that calculation which is very bleak but that falls down on two points as well, 1) I think it might be reasonable to assume that it takes people longer to completely recover than die 2) it's far more likely for cases to be understated than deaths since people who aren't that ill won't even go to the hospital and if they do and there are limited beds they are probably sent away and told to self-quarantine rather than being tested.
I question those higher mortality rates. Every website I looked reported that the SARS infection had close to a 10 % mortality while the official numbers of the coronavirus indicate that while the total number infected almost the 7700 infected from SARS that has come in just 2 months much faster then the SARS outbreak the mortality is 170 which is about 2.2 %. This could increase of course, but claims of a higher mortality rate like in Hong Kong may be hearsay. The numbers may be much higher, but without evidence for it is pure speculation. The coronavirus is expanding much faster then SARS did because it has a longer incubation period 14 to 10 days. And it appears to be transmissable from asymptomatic carriers. That does not necessarily translate to a higher mortality rate.
@@____Neo That is not at all how mortality is determined. The number of infected people is now at 7,700 people and those 171 who died is 2.2 % of the number infected.
I think I learned more from Dr. John Campbell in two days of watching his videos than in my years at school. Thank you so much for top rate content sir.
Very clear explaination. Thanks. I have two questions: 1. The mortality rate of 2% is not comparable to the 10% in SARS. The total figure in SARS is accurate and the infection complete, and the 10% or so is accurate. But the 2% on the 2019-nCoV is calculated on deaths to date vs infected persons to date. Would it be more accurate to calculated against infected people two weeks, or whatever the incubation period is. 2. What is the mechanism to spread the virus during the incubation period if you believe it is contagious then. As the patient has not yet presented symptoms, how is the virus spread?
No, it doesn't make sense to compare deaths to infections two weeks ago, because people who were infected two weeks ago are only being reported now. If you want to backdate you would need to know the average time from someone *reporting* infection to them dying, not the incubation period.

the unknow is that a sample populatio will have healthy individuals (less risk of succumbing).and not so healthy imdividuals ( with a high risk of succumbing)..also we have the mutation variable which could set it off on an exponential tangent that's not being considered the important thing to remember is that if it does go off you will have to run its course which means many infected individuals and of them quite a few deaths mostly immune-compromised very old and or very young
"Can be infected through the droplets" Correct me if I'm wrong, the countries with most humidity will have faster rate of infections than countries with low humidity because of the sustained droplets in air ?
Why they say 2% mortality rate when the new registereds have about 80 days to develope or recover from the illness? This is like when they diagnose you with cancer and you still alive you won't die in the future. We should measure the numbers accordingly. Like the first 100 patients 11% died 30% recovered the rest is still under care.
Dr., you are the very best at explaining this problem. Please keep this good work up and uptake the public as often as you can without becoming exhausted. I thank you.
@Dr. John Campbell what of the latency of this virus from symptom onset to hospitalization to death (of the cases in which it has occurred)? From the information currently gathered, it takes anywhere from 7-14 days from which patients have begun hospitalizing themselves to when they die in these particular cases. Could it not be inferred that we are not seeing the current distribution of those infected with current confirmed cases and those that have died from the respiratory complications caused by the virus? Could we not be possibly seeing a reflection of the confirmed cases of anywhere from 1-2 weeks prior, and thus a lethal rate higher than the widely proposed 2-3% based on current statistics of a latent effect?

The Spanish Flu came when millions of people were already sick with TB.
It could cut the population by a quarter. Or maybe a half.

Really?
SARS was initially reported as 3-4% death rate and ended up being close to 10%. This is because the deaths of the current infected haven't happened yet.
Yes, they look at today’s infection numbers and calculate a death % of that but they should calculate it from the numbers of infected 2 weeks ago when today’s dead got infected, and then the numbers would be a lot higher as %. It’s going to change society , the economic shock will be incredible. China is the global factory. If goods don’t get made and people don’t move around the economies will go into freefall
Dr. Campbell, thank you for a clear layman’s explanation of this viral progression in the body. I will be watching more.
Death rate may be higher since it takes days for people to die so I would think you would compare death rate with number of people infected a few days ago. What is more concerning is the 20% complication rate.
Al Katawazi agree. It’s the complication rate that concerns me the most. At one point it looked like 20% severe and 5% critical. It’s too soon to know what the actual figures but the spread rate is def concerning. Containment is the only way we can ‘win’ this battle.
That fact u need one of those special beds to take care of someone ”ebu” I think it's called that. Are limited and I think the United States has a majority filled?
And then 20 million caught the virus,there is no way to treat 20 million at the same time,then the death percentages increase
@@josephpa05 Yes, there's not enough. And there's not enough quarantined beds from my understanding as well. It is "ICU".
Not sure what they're going to do.
It could be higher due to the reasons you stated. But it could also be lower, since it's also possible that a lot of people who had it could have just thought they had a cold and didn't even go to the hospital and nobody outside of China has died yet.

I read this in an article:
We have obtained biochemical and electron microscopic evidence of conformational changes at pH 8.0 and 37 degrees C in the coronavirus spike glycoprotein E2 (S). The importance of these changes is reflected in the loss of virus infectivity, the aggregation of virions, and increased virus-induced cell fusion at the same pH. Coronavirus (MHV-A59) infectivity is exquisitely sensitive to pH.
(For example, your doctor may give you sodium bicarbonate (baking soda) to raise the pH of your blood.)
So baking soda the cure?

It's those that already have lung damage and scar tissue. Their lungs aren't elastic and this kind of infection could pose a serious problem. Those that tend to get aspergillus as a result of pitted lungs from previous damage are also at risk of more serious outcomes and those that recently had lunch surgery and are on retroviral medicine to fight rejection. Lung patients are likely concerned as they're already high risk. We're not even yet talking about the HIV patients prone to an aggressive form of MAC. Asthmatics also and the elderly.

Question - How can a Mortality Rate comparison be made between SARS and current NoroVirus. Looks.like the SARS rate was known only when the disease ended. Current NoroVirus has not ended. I think the mortality rate cannot be know at this point in time. I'm curious about that, just asking...
I have watched many videos, you Sir, are the Best Teacher !!!
Much higher than 2%, wait for mature statistics before comparing to SARS.
lets say the virus takes 1 week from reported infection to reported death, then youd have divide the total deaths now with the number of infected from 1week ago. that makes the fatality rate much, much higher at around *15-25 %*.
Yes we should wait for 30 days to get this number
I'm convinced China is under reporting infections. Supposedly, they are secretly cremating people that have died from this.
15 per cent.
@Stinky Piece of Cheese I did until a couple hours ago, it was, I believe, the head of Harvard molecular microbiology, it has been removed.
You have complete data of SARS to do a mortality rate. It takes a few days for confirmed patients to die, so a more accurate figure is take today’s death toll and compared that to the total number of confirmed cases a few days ago..
Confirmed cases vs. deaths isn't the mortality rate, cured cases vs. deaths is mortality rate. It's a 60% mortality rate right now according to the data available.
@Bill Whittaker just like the flu.
@Bill Whittaker the disease statistics are very odd right now, Hard to interpret anything without more data but it's tracking cured vs deaths at 60%, we will see a better picture as more data comes in.

As of 30 Jan, good quality patient care may be keeping the present cohort of patients alive longer. As with SARS, it may turn out that deaths may occur after weeks or months. Survivors of SARS reported severe long-term fatigue symptoms were a major problem for some 40% of SARS patients, lasting years.
If the disease were to spread rapidly, large numbers of those who are at present keeping patients alive might be worn out and debilitated or even infected and unable to perform their specialised tasks. The demand for oxygen, mechanical ventilation (and experts to operate it and nurse / treat the patients) would be overwhelmed.
Spread of significant illnesses like this can threaten the functioning of a modern society in new ways. Without the small number of qualified skilled operators, who would run the power stations, water treatment plants etc? Just-in-time delivery systems would fail rapidly, as we rely on a small number of truck drivers to deliver huge quantities of food to shop shelves. A lot of fresh produce is stored not in warehouses but in the refrigerated trucks that are constantly on the road from distant farms. Without them, we would be in trouble.
Even the fear of the illness on its own poses a risk for society, with the possibility of unrest and dissent. In any country with a repressive regime or with limited resources, there is a big risk of societal breakdown.
Great Videos. Just one question. When SARS started getting media attention I remember that the WHO first talked about a mortality rate of about 2-3% ultimately it turned out to be about 10% (and some regions had even higher rates). I looked it up and the mortality rate itself also followed an approximate bell curve pattern, starting with 1-2% and went up to 22% at its maximum and then went back down to 2%. Can you shed some light on this phenomenon?
It'll probably be because of how many people have it and when they got it, meaning severe symptoms occur at different points, so people merely haven't been infected long enough to have died yet, and then a surge may happen, and then it'll go down again
idk though I'm not reliable I'm not a professional
You seem to have little knowledge of the subject.
nCOV would appear to have a CFR of greater than 3%, the RO is in excess of 3, the SCR is circa 18%
So if you extend the infection over time and the deaths over time graphs as more data becomes available.
You will see a much steeper curve than for SARS.
Do not make the mistake of comparing a finished cycle i.e. SARS directly to an early position nCOV
The infection rate here is that of a pandemic.
I am in Guangzhou and see at first hand. The best we can hope is no mutation before early stage vaccine.

Hello Dr. Campbell,
I am wondering what the data of Total Deaths vs. Total Recovered means. Is the death rate measured as a ratio of Confirmed Cases or as a ratio of Recovered Cases? As of 4:00 PM GMT today 1/30/2020, there have been 171 deaths and 143 recoveries. Is this normal, or should we be seeing more recoveries than this? Is the death rate underestimated as a result? I am worried about underestimating the severity of this infection. Thanks.
14 day incubation, R naught around 2.6, mortality rate 2% and about four million people flying internationally every day. Asymptomatic transmission confirmed in Germany, Japan and I think Vietnam today. Any comments Dr. John?

I have a friend with a T-cell count of 250 (with diabetes), another with a count of 400. Are they likely to die if they contract nCoV? They live in NYC.
@Philip Gibbs Air travel itself would be risky until your immune system recovers from the chemotherapy. Ask your oncologist.
The death rate, you take todays deaths and go back 2 weeks for those infected at that time for the disease to take its course. Two weeks ago the infection rate was 1000 and todays deaths are 170, so about 17% death rate.
thankyou sir. i'm a chemistry student and i really enjoy this subject. great explanation, easy to understand.

Question about T cells - when someone runs a fever, aren't the T cells activated? For some reason I'm remembering T cells associated with viruses.

Thank you, Dr. John Campbell, for this educational video.
Excellent teaching, thank you Dr Campbell.
Its not excellent teaching out theoretical numbers, he should know better.
While calculating MR we should take into account a lag between got infected and got dead. So we should divide number of ones who died today to number of ones who have infected by today minus x ( x= how many days it takes to die once being infected ). If you do this calculaltions you will see that MR is about 7% which is much much worse than SARS
@Roger Clemons MR of SARS wasn't 30%, you probably mixing up SARS with MERS. 90% of infected with SARS had very mild symptoms and recovered, but for the rest 10% MR was different for different groups,for those who were over 50, MR was close to 50%, for overs 5-15%. As for 2019-coV, we dont know for sure yet, we dont know the denominator: how many have been infected? Threre's probability, that most of infected have light symptoms and are not registered as infected, recover in few days. We are in the very beginning of the epidemy and dont have correct input data. My previous comment was about using wrong method. Not about exact numbers, which are going to be precise when this outbreak is over.

15% mortality rate 83% infectious rate According to Hong Kong source Taiwan news
Yes, that would make more sense. Everyone is calculating mortaility rate wrong. They divide number of deaths with number of infected but forget it's not something that was in the past and is over now (like SARS), it's ongoing and every day number of infected increases significantly. The correct way to calculate the mortality rate would be to divide current number of deaths with number of infected as it was N days ago. That would equal 15-20% which is more realistic than 2-3% seen all over the media.
@@____Neo I thought about that calculation which is very bleak but that falls down on two points as well, 1) I think it might be reasonable to assume that it takes people longer to completely recover than die 2) it's far more likely for cases to be understated than deaths since people who aren't that ill won't even go to the hospital and if they do and there are limited beds they are probably sent away and told to self-quarantine rather than being tested.
I question those higher mortality rates. Every website I looked reported that the SARS infection had close to a 10 % mortality while the official numbers of the coronavirus indicate that while the total number infected almost the 7700 infected from SARS that has come in just 2 months much faster then the SARS outbreak the mortality is 170 which is about 2.2 %. This could increase of course, but claims of a higher mortality rate like in Hong Kong may be hearsay.
The numbers may be much higher, but without evidence for it is pure speculation.
The coronavirus is expanding much faster then SARS did because it has a longer incubation period 14 to 10 days. And it appears to be transmissable from asymptomatic carriers. That does not necessarily translate to a higher mortality rate.
@@michaeldeierhoi4096 Time will tell.
@@____Neo That is not at all how mortality is determined. The number of infected people is now at 7,700 people and those 171 who died is 2.2 % of the number infected.
Thank you Dr.🙏
I think I learned more from Dr. John Campbell in two days of watching his videos than in my years at school. Thank you so much for top rate content sir.
2 years in school
Very clear explaination. Thanks. I have two questions:
1. The mortality rate of 2% is not comparable to the 10% in SARS. The total figure in SARS is accurate and the infection complete, and the 10% or so is accurate. But the 2% on the 2019-nCoV is calculated on deaths to date vs infected persons to date. Would it be more accurate to calculated against infected people two weeks, or whatever the incubation period is.
2. What is the mechanism to spread the virus during the incubation period if you believe it is contagious then. As the patient has not yet presented symptoms, how is the virus spread?
No, it doesn't make sense to compare deaths to infections two weeks ago, because people who were infected two weeks ago are only being reported now. If you want to backdate you would need to know the average time from someone *reporting* infection to them dying, not the incubation period.
the unknow is that a sample populatio will have healthy individuals (less risk of succumbing).and not so healthy imdividuals ( with a high risk of succumbing)..also we have the mutation variable which could set it off on an exponential tangent that's not being considered the important thing to remember is that if it does go off you will have to run its course which means many infected individuals and of them quite a few deaths mostly immune-compromised very old and or very young
Sir, you are a wonderful teacher 🙏🏽❤️
Oh, thanks! This is a great virology lecture!!!

Thank You Doctor, very clear and enlightening explanation.
"Can be infected through the droplets"
Correct me if I'm wrong, the countries with most humidity will have faster rate of infections than countries with low humidity because of the sustained droplets in air ?
Not so wrong, and not totally right.
Interesting point, however when there is higher humidity the temperatures are normally higher and higher temperatures reduced spread to some extent.
Why they say 2% mortality rate when the new registereds have about 80 days to develope or recover from the illness?
This is like when they diagnose you with cancer and you still alive you won't die in the future.
We should measure the numbers accordingly. Like the first 100 patients 11% died 30% recovered the rest is still under care.

@Dr. John Campbell what of the latency of this virus from symptom onset to hospitalization to death (of the cases in which it has occurred)? From the information currently gathered, it takes anywhere from 7-14 days from which patients have begun hospitalizing themselves to when they die in these particular cases. Could it not be inferred that we are not seeing the current distribution of those infected with current confirmed cases and those that have died from the respiratory complications caused by the virus? Could we not be possibly seeing a reflection of the confirmed cases of anywhere from 1-2 weeks prior, and thus a lethal rate higher than the widely proposed 2-3% based on current statistics of a latent effect?
