NOURNEWS- Dr. Payam Tabarsi, regarding the possibility of recurrence of those who have recovered from Covid 19, said: "Since the disease is new, it is not possible to comment on it with certainty. However, at present, according to the available evidence, it is not possible to recur." Called recurrence and re-infection in Asian countries, it has been a continuation of the same initial infection and, as a result, a negative test for people who have not recovered.
He continued: "So if someone is infected and recovered, they will not be infected in this period, but if the disease does not disappear and in the next period it reappears in October and November, in case of mutation and change in virus behavior, there is a possibility of re-infection." There are improvements to the mutated virus.
According to the Infectious Diseases Specialist, in the next period, by examining the behavior of the virus and the amount of antibodies remaining in the body of the recovered, this question can be answered, that is, the possibility of recovering from the recovered. However, if the virus mutates and the remaining antibodies are low, the survivors will be at risk again.
"Using a mask is one of the most effective ways to prevent the transmission of the virus, because transmission through respiratory droplets during talking, sneezing," said the head of the Center for Clinical TB Research and Epidemiology at Masih Daneshvari Hospital. And coughing is the main way of transmitting Covid 19, but the type of mask used is also important.
"Even fabric and home masks have been approved," he said. They are severely repulsed, leading to further spread of the virus and putting those around them at risk, so people with symptoms should wear a simple surgical mask.
