Reuters reported that the World Health Organization (WHO) has entered into a review of scientists' suggestions to strengthen Corona19's defenses.

This is in response to 239 scientists from 32 countries warning WHO in an open letter that corona19 can spread even with aerosols much smaller than droplets.

WHO spokesman Yasarevic told Reuters that "we are reviewing the open letter with experts."

In the meantime, WHO has maintained that the primary route of transmission of the Corona19 virus is respiratory droplets, and that aerosol-induced air infection can only occur in certain situations in the operating room, such as bronchial intubation.

If the WHO admits the spread of aerosols, Reuters predicted, although it would have to change a number of recommendations, such as placing a meter or wearing a cloth mask, it is still unknown.
