My feeling is one of concerned calm, I guess you could say. Many afflicted people have minor symptoms while others, some healthy-some not, go on to have severe, if not life-threatening, experiences. Being 65 and diagnosed (as a non-smoker) with COPD, I would have about a 1 in 10 chance of being in that second group. I have an adult son with a poor immune system who gets everything including MRSA, and a stepson with advanced lung cancer. It's scary for that reason even though there's nothing to be done about it. I don't want to panic. I DO choose to be prudent and informed, however.
So, knowing that I may need to have to stay home for up to a month, I am going to get my prescriptions filled and order a few food and health items - dried beans, soap, tissues, etc. - to tide me over. Given that I live 20 miles from the first person in the US to become ill from a community source and not a traveler, I'd rather be a little more prepared than not.
Re/ the debate about contagion and fatality rates, this is from an article published today in the The New England Journal of Medicine:
^COVID-19 poses a serious threat to the world because it’s far more deadly and contagious than many other deadly viruses. First, it can kill healthy adults in addition to elderly people with existing health problems...Second, Covid-19 is transmitted quite efficiently. The average infected person spreads the disease to two or three others — an exponential rate of increase... World health leaders say the disease is spread by people who are mildly ill or don’t show any symptoms at all, making it harder to contain and more contagious than other types of viruses.
The mortality rate is many times more severe than typical seasonal influenza...The World Health Organization said the mortality rate of COVID-19 can differ, ranging from 0.7% to up to 4%, depending on the quality of the health-care system where it’s treated... Its current average estimated fatality rate of around 1% places it somewhere between the 1957 Asian flu pandemic (0.6%) that killed 1.1 million people and the 1918 Spanish flu pandemic (2%) that killed 50 million around the world, according to data from the Centers for Disease Control and Prevention.^
