Face masks with other preventive measures, such as frequent hand-washing and social distancing, help slow the COVID-19 infection.
Respirator masks such as FFP2, FFP3, N95, and N99 should be used for protection instead of a surgical mask because it can filter out both large and small particles when worn. Thus, face coverings can significantly help reduce the risk of transmission.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
