Wearing a mask is certainly not an iron-clad guarantee that you won’t get sick – viruses can also transmit through the eyes and tiny viral particles known as aerosols. However, masks are effective at capturing droplets, which is a main transmission route of coronavirus. Face masks can play a role in preventing the infection, but that role is limited in real world situations. There is some evidence that wearing a face mask can protect you from transmitting the virus from your hands to your mouth, probably because you are paying more attention to NOT touching your face when you’re wearing it. You also have some protection from “splash” droplets if an infected person sneezes or coughs around you. If you are likely to be in close contact with someone infected, a mask cuts the chance of the disease being passed on. If you’re showing symptoms of coronavirus,or have been diagnosed, wearing a mask can also protect others. So masks are crucial for health and social care workers looking after patients and are also recommended for family members who need to care for someone who is ill- ideally both the patients and carer should have a mask. However, masks will probably make little difference if you’re just walking around town or taking a bus, so there is no need to bulk-buy a huge supply. The biggest concern that doctors have around recommending masks is the false sense of security that might come along with  wearing one. There are a lot of reasons why face masks are not ideal. For example,it’s really hard to find one that fits perfectly around your nose or mouth or to keep it on for a long period of time. The minute you scratch your nose or touch your mouth behind the mask, you’ve lost the protection that the mask is supposed to offer. It has been suggested that wearing face masks could be useful if you’re sick in order to prevent you from sneezing or coughing into somebody’s face. But, a mask that is used to stop getting an infection is sometimes not very effective because people take it off to eat, many times they are worn improperly and if they get wet and somebody sneezes on that mask it could pass through. So, there is really not a lot of evidence (to support wearing a mask).
