Covid-19 crisis: WHO acknowledges 'emerging evidence' of airborne spread

The World Health Organization (WHO) on Tuesday said it is looking into claims of airborne transmission coronavirus in poorly ventilated closed settings and will soon issue a scientific brief on the issue. “We acknowledge that there is emerging evidence in this field... We have to be open to this evidence and understand its implication — regarding the modes of transmission and precautions that need to be taken. 

A comprehensive package of intervention is required to stop transmission (of the virus),” said Benedetta Allegranzi, technical lead, WHO infection prevention and control hub and task force, in Geneva. In an open letter 239 scientists across 32 countries said that novel coronavirus in smaller particles in air could infect people.
