Viruses killing thouands are not new because TB is estimated to infect 10 million plus people a year with 1.3 million dying and a mortality rate of 3%. As it is not a 1st world disease unless an outbreak close to a media station it is ignored.
US CDC estimates flu season in the US has 40 million infections per year with circa 60,000 plus deaths in a normal year but because the data is not fully recorded and someone dying on cancer who has flu can be recorded in either or both or something else.
Where do I start? The only similarity between Covid19 and flu is that they are both RNA viruses. The nearest relatives to Covid19 are some of the viruses which cause the common cold.
And TB of course isn't a virus at all, it's a mycobacterium.
