Yesterday, the World Health Organization walked back its statement that asymptomatic transmission of COVID-19 is “very rare.” This was after COVID-19 deniers had had a field day using that statement to attack social distancing, contact tracing, and mask wearing. It was a science communication disaster.
A story claiming that the WHO just said that asymptomatic COVID-19 patients don’t transmit coronavirus. Spoilers: It didn’t. However, the WHO’s message added unnecessary confusion and led COVID-19 deniers to say masks and social distancing are not necessary.
