A person infected with the Coronavirus without symptoms is a carrier of Covid 19 in the body but is still healthy or has been infected with the pathogen but does not have any unusual signs or symptoms.

In this case, the patient has not shown any signs of illness, but if for some reason the resistance declines, the body will quickly be attacked by the virus and cause illness.

The healthy form of people carrying the disease without symptoms is very dangerous because they can excrete pathogens into the outside environment, causing them to spread to other people, risking an outbreak.
