People infected with corona can once again become infected with the virus, according to a study.
A study of more than 3,000 people found that cod infection is common in young people and that despite being sick for the first time, these young people can become infected again and pass it on to others. Are
Research has shown that it is important to provide vaccines to people infected with coronavirus, as vaccination strengthens the immune response, protects against recurrence and reduces the rate at which the virus is transmitted.
Research has shown that although those who have been protected from cod in the past are five times more likely to develop the disease than their predecessors, the risk of re-infection remains.
The study included 3,249 men between the ages of 18 and 20 who were quarantined for two weeks before enlisting in the Marine Corps.
