WHO statement on masks was misleading but I didn't see it as wrong (only wrong in the sense that they should focus on people's perception of their statements). They said that there was no evidence that masks help. Which was true at the time. They paired that statement with suggestions use a variety of prevention methods.

The statement from Dr. Maria Van Kerkhove that symptomatic patients being "very rare" was definitely wrong. But she back tracked the next day and said it only possible they are rare and was aware of the 40% models which have now come out to be much closer to the truth.
