FAQ n.115285

Medical face masks should be worn. “Community” or “hand-made” masks do not achieve high level of protection. This is because a medical face mask is manufactured to a known standard. This is not true for community masks and handmade masks. The primary reason for wearing a mask is to stop transfer of the virus to other people – bearing in mind that some people may have the virus but show no symptoms. Therefore, everyone should wear a medical face mask to ensure a standard level of protection. 

Where higher standards for masks are required on national level, travellers should comply with such standards.
