When to wear a mask ?

Wearing a mask in a preventive manner is not recommended by the World Health Organisation (WHO) as a means to avoid contamination with the COVID-19 virus. The WHO recommends that health personnel, who themselves have respiratory symptoms, should wear a surgical mask to avoid contaminating others. The use of special masks (FFP2) to prevent infection with coronavirus only makes sense in hospitals where patients infected with coronavirus are treated and for the analysis of the body material of these patients. Wearing an FFP2 mask is necessary for healthcare personnel when a test (nasal swab) is performed on a patient. Similarly, the laboratory technician must wear a surgical mask to be able to handle respiratory samples.
