We accept chickenpox is in the air, and this is what was said about it in 1980.

Sound familiar?

Even the denial is the same as we see today.

Airborne spread has never been UNEQUIVOCALLY demonstrated
[ed: onus much?]

Low secondary attack
[ed: next you'll be referring to R0]

What a bore. Come up with new excuses.

Again, "airborne" (meaning long-range) vs "direct", when both are through the air.

And, as I keep saying "airborne" doesn't even have a definition. 5 feet? 6? 8? Around a corner? Up a flight of stairs?

Who knows?! We're winging it! (Airborne style, I guess)

Here's another one.

Index remained in isolation in room. 8 of 70 caught it, and seems like on a quick skim all 8 were there one afternoon.

Hmm, hit rate far less than some case descriptions of COVID-19.

One wonders if people are reading these old case descriptions or not.

That one is from

These would be the outbreak reports of airborne chickenpox by 1988, at least as cited in an article in that year.

LeClair is #1 above.

Gustafson abstract is #2.

Here's another - one index gave to three, then they vaccinated the ward.

No direct contact.

How long did that take me, to pull half the old case reports cited.

Not really close to a year, that's for sure.

Do your jobs.

Let's have some comparison fun. Totally not scientific, of course.

2/2

1 to 20, but not sure if all caught it at event or just down the chain.
