World Health Organisation (WHO) has said COVID-19 virus spreads from human to human transmission through large droplets from the nose or mouth, expelled by infected through coughs, speaks and sneezes which falls on surfaces. Which is why WHO's primary guideline is to wash your hands frequently, cover our mouths and social distancing. 
 
However, hundreds of scientists say there's evidence showing that the novel coronavirus in smaller particles can be transmitted through air and are asking WHO to revise recommendations. 
 
As per the reports of the New York Times, 239 scientists from 32 countries wrote an open letter to World Health Organisation, outlining the evidence stating that the smaller particles can infect people. 
 
During a press meet, the members of World Health Organisation didn't comment on the matter when requested by Reuters. 
 
Dr. Benedetta Allegranzi, the WHO's technical lead of infection prevention and control said, "Especially in the last couple of months, we have been stating several times that we consider the airborne transmission as possible but certainly not supported by solid or even clear evidence."
 
However, medical experts across the globe believe COVID-19 is an airborne disease and can infect people if the smaller exhaled droplets are inhaled.
