CDC Removes Guidance Update On Coronavirus Transmission

The video discusses how the coronavirus is primarily spread through small respiratory droplets and aerosols, especially in poorly ventilated indoor areas. The CDC updated its guidance to reflect this but later removed the information from its website. A CDC official stated that the removal does not reflect the current understanding. Previously, the CDC emphasized large droplets from coughing and sneezing as the main transmission method. The guideline changes were not widely noticed until reported by CNN.

When were the guidelines regarding the virus transmission changed?
