In other news, the South Dakota governor was hugging Trump Jr's girlfriend a day before the gf was announced as positive. That next evening, the governor apparently took a flight on Air Force one and chatted with Trump Sr without a mask.  (She had tested negative  before Trump arrived at Mt Rushmore)

Did WH staff know she had close contact?  Seems risky to let her close to the president even with a negative test.   Or I wonder now if Trump will start taking hydroxychloroquine, just in case.

Incubation period is too short; it is generally 3 - 14 days, so even if the governor has contacted COVID-19 from Trump Jr's girlfriend, Noem is very unlikely to have been infectious.

I think serial interval (time between the onset of an infector's symptoms and the onset of an infectee's symptoms) might be more relevant.
(I interpret this as being an upper bound on the mean value for how long from exposure to infectious.)
It is shorter than the incubation period, but still 1.5 days seems too short from exposure to infectious.

One unpublished study: 5.29 days (4.72, 5.86).
An earlier letter from the same authors:  3.96 days (3.53, 4.39)
Another unpublished study: 4.56 days (2.69, 6.42) Taiwan;  4.22 days (3.43, 5.01) Tianjin
Another study: 4.6 days (3.5, 5.9)
