Health workers who have appropriate personal protective equipment including protective suits, masks, gloves, goggles, face shields and gowns don’t develop COVID-19 symptoms or test positive for the virus, a Chinese study suggests.

Researchers examined data on 116 doctors and 304 nurses who were deployed to Wuhan for 6-8 weeks from 24 January to 7 April.

They were all involved in aerosol-generating procedures and provided with appropriate PPE to care for patients with COVID-19.

Participants worked four- to six-hour shifts over an average of 5.4 days per week. They spent an average of 16.2 hours a week working in ICU.
