Second Wave of Corona Virus is aggravating day by day. The Indian Council of Medical Research (ICMR), under its first-of-its-kind practice, has attempted to identify those who have been re-infected with Covid-19 in the country. The journal Epidemiology and Infection has given its consent for its publication.
This is how determination happens
Scientists consider genome analysis of virus samples for evidence of re-infection. Since the virus is constantly changing, there should be some difference in the genome sequence of the two samples. However, samples from all infected are not being collected for genome sequencing, as this would be a major challenge. Only a few people’s samples are sent to study.
This is how study happened
1,300 people who were re-infected were studied. It was found that 58 of these, or 4.5 percent, could actually be classified as re-infected. They were infected for the second time within 102 days. He was also investigated in the meantime, the report of which came negative. He was 20–40 years of age and had 12 health workers. ICMR scientists studied both reports of the patient for at least 102 days instead of genome analysis. The American Center for Disease Control believes that viral shedding (the spread of the virus in the body) takes about 90 days. Another investigation was conducted by the scientists within 102 days to deal with the possibility of viral shedding, which turned out to be negative. However, these 58 would not be considered a confirmed case of re-infection in the absence of genome analysis.
Why is it useful
It is not clear yet when a person is corona infected, their body develops a permanent immunity or it may become infected again after some time. It is also necessary to detect the possibility of being infected again so that this epidemic can be fought with vigor. This will not only help in the strategy of fighting the epidemic, but it will also make it easier to understand how much more people will have to follow the laws of masks and physical distance. It will also be helpful in the vaccination campaign. Cases of re-infection are coming all over the world including India, but not all can be placed in this category.
