SARS-CoV-2 that results in COVID-19 has killed over 52,000 people to date and it's only infected 0.01% of the world population. Because humans don't have an immunity to it, this virus will infect at least 90% of us. Extrapolating from the current numbers results in a total death count of 468 million people worldwide. Another way of calculating the fatality count is to take the current global mortality rate of 5%, resulting in 390 million deaths worldwide. There is no way that SARS-CoV-2 can be considered on par with the common flu. The article makes a major mistake in comparing a train wreck that is currently in motion to a bumper car wreck that has already happened in the past. This flaw in reasoning will be fatal to us all if it causes us to take half-hearted steps while we lie to ourselves that this is just a bad common flu.
Yes, there is an incubation period for COVID-19. It's on average 5.1 days from initial infection to presentation of symptoms. During this incubation period, studies have shown that the person is infectious to others. We are all going to need to wear masks in case we are infectious to others, otherwise, this virus will successfully infect most of humanity. Humans have no immunity to SARS-CoV-2 that causes COVID-19. Nearly all of us will get it unless we get vaccinated with a vaccine that doesn't yet exist. (Note: The 12-18 month quote for a vaccine is not based on good science reporting. This timeline is entirely hope and dreams at this point.)My question is, is there an incubation period for COVID-19? My impression is that it’s contagious for 14 days prior to one showing symptoms — Is this true, and is a true for all cases? That would make it very hard to stop an pandemic. From what I read SARS was contaned because it wasn’t contagious until one showed symptoms of it. So they were able to quarantine the one with SARS immediately and eventually track down everyone who had it. If you can’t tell who have corona virus and you can’t test of everyone, it seems very difficult to stop it.
Secondly, how contagious is it? Hundreds of people on the cruiseship acquiring it, or 50 people in the Washington nursing home getting it in a few days seems quite telling.
