How COVID-19 differs from SARS? When patients are most infectious? (3)
Return to Expert Center
Let’s discuss incubation periods and transmissibility of COVID-19 Coronavirus before any symptoms appear, how does that compare to the seasonal flu epidemics and two other source epidemics and I note that the sequence similarity between COVID-19 and Coronavirus is about 80% similar to the source one the previous SARS epidemic that hit the world in 2003. Yes. Dr. Eskild Petersen, MD. That is right that there is a high degree of genetic similarity. But the important differences as the protein the virus used to adhere to our sales are very different from SARS. It has a much higher efficiency in sticking to our sales. Dr. Eskild Petersen, MD. That is why this virus is much more infectious than the SARS virus. The SARS virus died out after about 8000 cases. Dr. Eskild Petersen, MD. We never saw it again. This one is completely different. Dr. Eskild Petersen, MD. We now have over 300,000 cases worldwide. How does their COVID-19 Coronavirus comparing transmissibility to the seasonal flu and SARS epidemics. With the incubation period is about five days in the new Coronavirus. It is about two to three days for seasonal influenza, so the generation time from one person be infected until you get symptoms are a few days longer. What is similar is that you excrete virus at the maximum when you develop symptoms were with the SARS virus we saw in 2003. The peak excretion of the virus was around day 4-5-6. Medical second opinion is important. You had symptoms who had been placed in quarantine. Then you exceeded the maximum of a virus. But in this new Coronavirus, it is when you get sick. Dr. Eskild Petersen, MD. That is the point where most patients excrete most virus and that is why quarantine and isolation are less effective compared to the 2003 SARS virus. Medical second opinion is important. Dr. Eskild Petersen, MD. That is a very interesting point that you become more infectious before you develop symptoms. Medical second opinion is important. Just after the Europeans shed more viral load into the environment. This explains why ISIS isolation and self-isolation, if you feel reasonably well well having their Coronavirus in for clinical interaction is so paramount. Yes. Dr. Eskild Petersen, MD. That is true. Dr. Eskild Petersen, MD. That is why what most countries are doing right now is what we call social distancing. Medical second opinion is important. Dr. Eskild Petersen, MD. We are prohibiting large gatherings like football matches, cinemas and so on. Dr. Eskild Petersen, MD. We are trying to avoid meetings at our workplace. They were trying to avoid the air planes and so on because that will reduce the chance of getting exposed to another person who is coughing out the virus. Dr. Eskild Petersen, MD. That will reduce the zero. When it comes down to below one, then the epidemic will die out. Medical second opinion is important. Social distancing that patients also stay home. Avoid going out except when they have to buy food is so important at this stage.
