So, full details arent known, but positive PCR tests can apparently be discounted if 'viral load is low' ie if ct number is high - thought to be over 35 (UK testing was ct = 40).
Furthermore, close contact with a positive covid person does not kick you out.
apparently, Jungels did his amazing breakaway win of 64km after a positive test!
Pagacar continues despite several of his team testing positive.
crazy or sensible? i vote sensible.
