Masks don't prevent the spread of coronavirus.

Masks are one of the measures required to limit the spread of COVID-19.

The two primary methods through which COVID-19 spreads is through respiratory droplets and physical contact, as pointed out by the World Health Organization(WHO). Hence, wearing a medical mask is one of the measures through which the spread of COVID-19 can be limited. However, the usage of masks alone is insufficient in providing an adequate standard of protection. Other guidelines like social distancing, no contact, and hand hygiene must be followed.

The CDC also recommends that everyone (including seemingly healthy individuals) wear a mask when venturing out in places where it is difficult to maintain social distancing. Experts suggest that face masks might help keep people with COVID-19 from unknowingly passing along the virus. Amongst N-95s, surgical masks, and fabric masks - N-95s are most effective since they seal around the face but not recommended for use by the CDC due to shortage. Researchers have detected the virus in tiny aerosol particles in all cases of influenza, rhinoviruses, and coronaviruses. Thus we know that the virus is airborne and can leak through the sides of the fabric and surgical masks. If viral particles are nearby, they have an easy path around a surgical or fabric mask. Hence, it is essential to follow social distancing guidelines and stay at home as much as possible while following proper hand hygiene.

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.
