Most of the other viruses have probably been classified as Covid! Similar symptoms mainly.
In the US deaths from heart attack dropped about 95%!
Covid generally has flu like behaviour that it could be "this season's flu variety".
Records & stats are shown to be all over the place.
Same cleanliness behaviour with HIV & no decrease in cold/flu then, or with the other sars viruses!
