The World Health Organization is considering a “precautionary measure air” to medical staff after a new study shows that can survive in the air in some settings.
virus is transmitted via droplets, or small pieces of liquids, mostly through sneezing or coughing, Dr. Maria Van Kerkhove, head of WHO’s disease emerging and zoonotic Unit, told reporters during a virtual press conference on Monday. “When you do aerosol-generating procedures such as medical care facility, you have the possibility of what we call aerosolize these particles, which means they can stay in the air a little longer.”
He added: “It is very important that health workers take additional precautions when they’re working on patients and perform the procedure”
health officials said respiratory diseases, droplets carried through sneezing and coughing as well as germs left on inanimate objects. coronavirus can go the air, remained suspended in the air depending on factors such as heat and humidity, they said.
Kerkhove said health officials are aware of some research in a number of countries see the different environmental conditions that COVID-19 can survive. The scientists specifically looked at how humidity, temperature and ultraviolet light affects the disease and how long it stays on different surfaces, including steel, he said.
Health officials use the information to make ensure WHO guidance is appropriate, and “so far … we believe that the guidance we have is right,” he added. Health officials recommend medical staff to use so-called N95 masks because they filter out around 95% of all particles of liquid or air.
“In the health care facility, we make sure that health workers use a standard droplet precautions with the exception … that they do aerosol-generating procedures,” he said.
Robert Redfield, director of the Center for Disease Control and Prevention, told Congress last month that the agency was aggressively evaluate how long COVID-19 can survive, especially at the surface.
“on copper and steel, it’s fairly typical, it’s pretty much about two hours,” said Redfield in the congregation house. “But I would say on another surface – cardboard or plastic -. That again, and so we see this”
Redfield add an infection contracted from the surface rather than through the air can contribute to an outbreak on a cruise ship Diamond Princess.
separately, the case of the Director-General of WHO Dr Tedros Adhanom Ghebreyesus over the past week, adding, “we have not seen an escalation of urgency in testing, isolation and contact tracing, which is the backbone of the response”
“We have a simple message for all countries .. test, test, test test every suspected case, if they test positive, isolate them and find out who they have been in contact with two days before they develop symptoms and tested people also, “Tedros said.
