A historical timeline of infectious disease transmitted in aerosols

Many diseases have been known to be airborne (transmitted in aerosols) over the years. Politicians and medical professionals should NOT have called SARS‑CoV‑2 (the virus that causes Covid-19) a droplet or fomite transmitted disease at the outset. Nor should they have stuck with this death/disability causing falsehood when they realized it was wrong. There was plenty of evidence from the past.
