Study: Corona infection makes a person less susceptible to a second infection for 10 months

A new study has found that people who have already been infected with the Coronavirus are less likely to contract the virus again for ten months, as researchers from the University College London (UCL) Institute of Health Informatics (UCL) looked at infections among home care residents and health care workers, using an antibody test. To determine who has previously contracted the virus, they compare those who were previously ill with those who did not have the virus.

According to a report by the British newspaper “Daily Mail”, the results showed that people who had previously been infected with the Corona virus were 85% less likely to test positive for Covid 19 again than their peers, and health workers were 60% less likely to be infected.

It is really good news that natural infection protects against reinfection in this period of time, as it has been proven that the risk of infection twice appears to be very low, and the fact that previous Corona virus infections provide a high level, said Dr. Maria Krutikov, a PhD fellow at the Wellcome Trust in the United Kingdom. The protection of elderly home care home residents is also reassuring, given previous concerns that these individuals may have less robust immune responses associated with age, she added, "These findings are particularly important because this vulnerable group has not been the focus of much research."

The research included 683 home care residents with a mean age of 86 years, and 100 home care staff in England, and any study participant who received a vaccine was excluded from the data 12 days after receiving the final dose in the vaccine sequence.

"This was a unique opportunity to look at the protective effect of natural infection in this group before vaccination was initiated," said lead researcher Dr. Laura Chalcross, a consultant in public health medicine at UCLA. An important next step is to investigate the duration of immunity after natural infection and vaccination and to assess, Whether this protective effect is maintained against current and emerging variables, the study found that although it is much safer than it was before, there is still a possibility that someone will contract the virus months after they have already been infected.
