The outbreak of pneumonia caused by the Wuhan coronavirus is ongoing in our world. More than half a million people have already been infected with the novel coronavirus, and 36,000+ have died because of it. Still, there are serious questions about almost any epidemic. Why do they (seemingly) occur more often? Why is there no universal medicine? And is it possible that they will infect the entire population of the Earth and doctors will not cope with them?
A universal strategy that completely protects against infection does not exist. In the case of each infection, there are nuances.
In general, for infections transmitted from person to person by airborne droplets, standard hygienic recommendations work well, so wash your hands more often and do not touch your face (many viruses persist for a long time on various surfaces and easily penetrate the body through mucous membranes). It makes sense to avoid crowded public places, try not to contact people who have obvious signs of the disease.
If you really want to, you can wear a surgical mask: some studies show that it is no less effective than a respirator, but it is important to do this constantly. If you periodically take off the mask to breathe and do not wash your hands, there will be no protective effect.
I have written a detailed article on the same topic which you can read here.
