A new study has shown that corona virus can survive in air in some settings. After this, the World Health Organisation is now considering “airborne precautions” for medical staff.
In a virtual news conference held on Monday, Dr. Maria Van Kerkhove, head of WHO’s emerging diseases and zoonosis unit, told reporters that the virus is transmitted through little droplets, mostly through sneezing or coughing. She told that while performing aerosol-generating procedure like in a medical care facility, you have the possibility to what we call aerosolize these particles, which means they can stay in the air a little bit longer. So additional precautions has to be taken by the medical officers while doing those procedures.
Health officials recommend medical staff wear so-called N95 masks because they filter out about 95% of all liquid or airborne particles.
