A Covid-19 outbreak is a real threat to the life of every individual. As we speak, there is a large number of people in the hospitals in critical condition. And it is not just the people who are in the hospitals, but also those who are at home and have fallen ill. It is the responsibility of every individual to ensure that they and their families do not become infected with the virus. But the problem is that a large number of people do not have any idea how the virus spreads. They think that if they have a cold, then it is all over. But the truth is that a person can be infected with the virus even if they have no symptoms.
