@croissant@zeroes.ca (cont) Until PCR tests available, you couldn't check who was infected. PCR tests took a few days for results, and would only be posistive a few days after someone was infected. By Jan 14, China had not yet had the time for: -PCR tests becoming available. -Person 1 gets infected, tests positive on PCR (few days elapse) -Person 2 has symptoms, didnt go to Wuhan market, gets positive PCR, and has had contacts with person 1. WHO's statement were scientifically correct at time made.
