Does anyone have any legit information about the virus? All I can find online is typical CNN, AP, mainstream outlet fear-mongering.
I don't think the media are fear mongering. There's a real possibility this virus might spread uncontrollably to the global population, and at the current 3% death rate, that would equate to 200 million dying worldwide (assuming the virus spread to most of the world's population).
In the 1918 Spanish Flu pandemic, up to around 50 million died worldwide. So it's not unheard of to have such a high death toll.
The Wuhan coronavirus would certainly spread to the rest of the world if there were not major efforts to control it. The basic reproduction number of the Wuhan coronavirus is around 3 (ref: here). This means that on average, every infected person will infect 3 further people. So clearly there would be an exponentially explosive epidemic if aggressive control measures are not put in place. Hopefully these control measures will prevent the explosive spread; but if these measures fail, then we might expect millions of deaths worldwide.
Furthermore, bear in mind that coronavirus is an RNA virus, not DNA virus (its genome consists of RNA, not DNA). RNA viruses have a much faster genetic mutation rate than DNA viruses, and so can mutate into nastier and more virulent forms once an epidemic starts. Or the opposite: they can also mutate into a more benign form.
This morning, the latest headline from mainstream media outlets was "The virus can be spread before an infected person shows symptoms".
What is new here?
It is the same with every flu and cold virus. Nothing new here. It is a respiratory virus.
Many viruses only become contagious once the first symptoms appear. For example, with Ebola, people are not contagious until they develop the first symptoms.
It's more easy to control viral spread if this is the case, because you can be assured if someone has no symptoms, they are not transmitting the virus to others. But with this Wuhan coronavirus, people can transmit the infection even before any symptoms appear. Which means that perfectly healthy-looking people who do not know they are infected can transmit the Wuhan virus.
The time between catching a virus and the appearance of its first symptoms is called the incubation period. Incubation periods can be as short as 12 hours, or as long as several months (or even years for some pathogens).
The incubation period of the Wuhan coronavirus is around 10 to 14 days. So if you catch this virus, you will not notice symptoms until around 2 weeks later; but during that first two weeks of no symptoms you can still transmit the virus to others.
I have seen "15% mortality rate", popping up in the news. Does anyone know if this is the estimated mortality rate of everyone infected (seems unlikely). People who are or were infected and did not have severe symptoms and did not check into the hospital, are probably not in the stats. If it is only 15% mortality rate of people who were sick enough to go to the hospital, then the overall mortality rate is probably much lower.
I think your figure of 15% refers to the mortality rate of the 2003 SARS coronavirus outbreak, which is related to the Wuhan coronavirus.
At present the Wuhan coronavirus has an observed mortality rate of 3%. That means out of all the people who got sick and were proven by blood tests to have this virus, 3% have died. This is not an estimated figure, but an empirical one. However, it's quite possible that many more people have caught this Wuhan virus than have been detected (because it's possible that you may be able to catch this virus and only have very mild symptoms, so you would not think to go to a doctor, and so would not be tested and included in the figures for the number of people infected). In which case, if there are many more with the Wuhan virus who did not go to the doctor, the mortality rate may be substantially lower than 3%.
So at the moment, it is not known whether the number of people proven to have Wuhan coronavirus represents all the people infected, or just a small fraction of the people infected.
