Even when the range of possible Ros is narrow, factors like contact rate vary from patient to patient. A person who gets sick might stay inside for the next week, or they might continue to take public transportation to their job, socialize with friends and family, and visit a new location .How well a virus spreads can impact how deadly it is.
"Infections, particularly respiratory infections — the more efficiency they gain in spreading, the less case fatality they have," Fauci said. That's why the H1N1 flu outbreak in 2009 "wasn't dubbed as a particularly serious pandemic," Fauci said. "That spread very, very well, but the fatality rate was quite low."
There are some exceptions to this, Fauci said, like the 1918 flu outbreak that was both highly contagious and deadly.is hovering around 3.4%, but experts think it could drop to about 1% as more mild cases are diagnosed. That's roughly ten times the death rate of seasonal flu.Though research on the new coronavirus is still in its early stages, and the world looks nothing like it did in 1918, the numbers have started to ring alarm bells.
"Covid-19 has started behaving a lot like the once-in-a-century pathogen we've been worried about," Bill Gates wrote in
You think!!!!
Spreading rate of 2.2 people on average is quite high? My feeling is that the number is less than I thought.
