KoraL If you wear a mask number 95 and do not wear glasses, then this is of little use, since the usual flu virus passes through the shell of the eye. Maybe the coronovirus is not like that? who knows? Exactly nothing is known about him yet!
If there are chronic diseases, then the risk is still increased significantly.
Yes, here you are right, if resources are scarce, doctors are not qualified, then the matter will be close to disaster.
That is, the coronovirus mutates, and can become even more terrible, giving the person side diseases.
On the other hand, coronovirus loves wet and warm weather; its effect on arid climate, dry and hot, has not been studied.
On the other hand, if there is no quarantine, if there is no possibility of remote work, and getting a salary ... this applies to third world countries, with an income of GDP of not more than 1,500-2,000 US dollars per year, then the risk of picking up the virus is great, as well as the risk of not getting proper treatment. Since there simply will not be specialists, there will be no medcine, there will be no funds (for example, oxygen devices) for treatment. And if it does, then with a high degree of probability it will be very expensive. With salaries of 150-200 dollars a month, one cannot survive. It remains to rely on good immunity, a miracle, and the fact that the virus will not come to such countries (but there is little hope for this).
The overall result is to wash your hands correctly if you are sick, do not go outside
