Śmiertelność - to nikłe 0,1% dla grypy to dane dotyczące wyłącznie USA (baza - statystyki CDC).
Christopher Mores, a global health professor at George Washington University, helped make sense of some figures. He calculated the average, 10-year mortality rate for flu using CDC data and found it was 0.1%. That 0.1% rate is frequently cited among experts, including Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. (…)
It’s important to note that, although this percentage seems like a small number, influenza is responsible for an estimated 30,000 to 40,000 deaths annually.
Dane na ten rok (2 mce): “85,779 Seasonal flu deaths this year”
Kolejny dowód na zaniżenie wskaźnika dla grypy:
The death rate from seasonal flu is typically around 0.1% in the U.S., according to The New York Times.
Wskaźnikiem śmiertelności COVID-19 można podobnie żonglować:
The WHO said in a press conference Monday that in Wuhan, China, the city where the virus emerged, the mortality rate ranged from 2% to 4%. Officials said that in the rest of China, outside of Wuhan, the mortality rate of coronavirus is 0.7%.
Co do zaraźliwości - COVID-19 jest ok.2x bardziej zaraźliwy od grypy, więc nie przesadzaj z tym dużo bardziej.
The measure scientists use to determine how easily a virus spreads is known as the “basic reproduction number,” or R0 (pronounced R-nought). This is an estimate of the average number of people who catch the virus from a single infected person, Live science previously reported. The flu has an R0 value of about 1.3, according to The New York Times.
Researchers are still working to determine the R0 for COVID-19. Preliminary studies have estimated an R0 value for the new coronavirus to be between 2 and 3, according to the JAMA review study published Feb. 28. This means each infected person has spread the virus to an average of 2 to 3 people.
Reasumując - nie bagatelizuję, ale jestem bardzo daleki od paniki.
