1. More on the rarity of asymptomatics with #Covid-19. In the latest rounds of Covid testing of Premier league footballers and staff, there were 0 positives among 2,787 tested:

2. There have consistently been very low numbers of positives among footballers and staff, even though:
a) these are among the only people who have not had to obey social distancing rules;
b) they travel all over the country and Europe; and
c) they cover the whole of the UK.

3. Can anybody shed light on whether confirmatory testing of positive results is done for the footballers? I understand their samples are tested by The Doctors Laboratory, a private clinic (which has incidentally been accused of health and safety breaches tinyurl.com/44p468e7)
4. Confirmatory testing could partly explain very low numbers of positives. In the Cambridge asymptomatics study only 6 of 43 positive PCR results were confirmed on retest. normanfenton.com/post/smashing-…
5. Whatever the explanations, the footballers and Cambridge data together suggest that when testing is performed regularly it is almost impossible to find Covid confirmed in asymptomatic young, healthy people.
