Study Finds Cotton Masks Fail to Effectively Filter Coughs from Covid Patients


Specializes in Peds, Med-Surg, Disaster Nsg, Parish Nsg.

A small study from South Korea cast doubt on the ability of surgical or cotton face masks to effectively prevent dissemination of COVID-19 coronavirus from the coughs of infected patients.

Whether face masks decrease transmission from asymptomatic individuals with COVID-19 or those who are not coughing needs further study, they added.

Study: Masks Fail to Filter Virus in Coughing COVID_19 Patients

I made a mask with a pocket to insert an air filter that claims to be able to filter virus particles 0.1 microns or larger. I am hoping this does better than nothing. But...I am fortunate to be able to stay home.

My greatest appreciation to those on the front line.
