Proof of asymptomatic spread?

Guest Post by Steve Kirsch

There are lots of places requiring COVID testing even if you are asymptomatic. That means there must be scientific evidence of asymptomatic spread. Where is it?

SurfAir is requiring me to be tested prior to their flights, even if I’m asymptomatic.

I asked them for the scientific evidence of asymptomatic spread. You know, like a randomized trial that might look something like this:

You have 20 groups of people who have tested negative on an antigen and PCR tests. You put an asymptomatic positive in 10 of the groups. You put a symptomatic positive in the other 10 groups. All groups are confined to a small unventilated room for 1 hour. You then measure the infection rates several days later. You may need to repeat to get statistical significance.

They did not respond.

There is no such randomized trial.

Papers attempted to assess this using statistical modeling (another example) which are not reliable enough to make a decision of this magnitude.

We know from real-world examples, that asymptomatic spread is very hard to find so if it exists, it is likely only going to be measured in a large randomized controlled trial.
