Let’s review again. How can covid-19 be infected? COVID-19 can be transmitted from person to person. It can enter the body through two channels. By inhaling the secretions of infected people.  It caused by coughing, sneezing, talking, singing, shouting, laughing, etc. And exposure to droplet secretions from infected people. This may be attached to public items such as door handles, elevator buttons, etc. 

One infected person can infect an average of 2-4 others. But the spread depends on the environment, weather, humidity and density of the crowd at that time.

Covid-19 risk group and environment that makes it easy to infect

As said, the epidemic of the COVID-19 virus will cause more or less people to infect. It depends on the environment, weather, humidity and density of people in that area.  In addition to direct contact with the infected person Risk areas or environments that are at risk of becoming infected easily are:

• congested area There were many people gathered together. 
• Closed areas with poor ventilation / air-conditioned rooms / car cabins / public vehicles with air-conditioning 

In the case of congregation in a poorly ventilated area. If there infecte people mix in without wearing a mask. People in that area are also at increased risk of contracting COVID-19. Even without direct contact with the infected person.
