Dear Reader:

My notes regarding the Thorax article of four days ago: it is about a cruise ship that departed Argentina in mid March and for 28 days there was no contact between the population within the ship (passengers and crew) and the population outside the ship. Therefore, the population within the ship was isolated. All of the passengers and crew were tested for Covid-19. This ship then, is the first and only situation were all of a population were tested for Covid-19.

100% of the population was tested for Covid-19. 41% of the population tested negative and 59% tested positive. 19% of those tested positive were symptomatic, and 81% were asymptomatic.

81% of the population that tested positive for Covid-19 was asymptomatic.

— what if about 81% of the global population is asymptomatic? On one hand it would mean that 81% of the population may infect others. On the other hand, it would mean that 81% of infected people do not get sick at all.

Currently, worldometer lists over 3 million global active cases of Covid-19, and 98% of the symptomatic being “in mild condition”.

— What if 19% of the population is symptomatic (and 98% of the 19% are in mild condition)..?

(Later, perhaps).
