Wearing mask is one of the measures to prevent respiratory tract infections. Surgical mask is a type of face mask commonly use. When used properly, it can help to prevent infections transmitted by respiratory droplets. Protect yourselves and protect others by always keep your hands clean, wear mask as appropriate and maintain cough manner…….

With COVID-19 case numbers exploding, an overshadowed aspect of the personal protective equipment (PPE) crunch is whether healthcare workers are able to use it properly — including taking it on and off without contaminating themselves or others.

he U.S. Surgeon General Dr. Jerome Adams acknowledged that the government’s guidance on masks “has been confusing to the American people,” he said at the news conference. Until now, the CDC had recommended that while health care workers and “people who have COVID-19 and are showing symptoms” should wear face masks, healthy people should don masks only when taking care of someone who was ill with the new coronavirus. The World Health Organization (WHO) recommended the same.

The National Academy of Sciences (NAS) has given a boost to an unsettling idea: that the novel coronavirus can spread through the air—not just through the large droplets emitted in a cough or sneeze. Though current studies aren’t conclusive, “the results of available studies are consistent with aerosolization of virus from normal breathing,” Harvey Fineberg, who heads a standing committee on Emerging Infectious Diseases and 21st Century Health Threats, wrote in a 1 April letter to Kelvin Droegemeier, head of the White House Office of Science and Technology Policy.
