The WHO acknowledges the new evidence saying COVID-19 could spread by tiny particles suspended in the air, but says it requires further assessment.
This finding would eventually lead to broader use of masks, even indoors. Researchers have advised that the possibility of aerosol transmission in healthcare facilities and other buildings where ventilation systems recirculate unfiltered inside air must be taken into account under prevention measures. But WHO also said that the evidence was preliminary and that further assessment was required.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
