There is a common belief that people, who once got infected with COVID-19, do not get infected again. The research performed by the UK suggests that a majority of people become immune to this infection for several months once they recover from COVID-19. However, the news of COVID reinfection leads to confusion and curiosity among people.
Let us learn more about the possibilities of COVID reinfection.
What Does the Study Say About COVID 19 Recovered Patients?
A study SARS-CoV-2 Immunity and Reinfection Evaluation was conducted on more than 20,000 health-care workers in the UK. It was found that a majority of people who get infected and recover from coronavirus infection develop resistance towards it for several months. The body develops immune responses from earlier infections that lessen the chances of getting reinfected again by 83% for five months.

Reinfections are rare and unusual. They affect less than one percent of 6,600 participants who got infected with COVID-19. The study also concluded that those who got reinfected carry a high amount of virus in the throat, and nose in spite of showing symptoms. This can increase the chances of virus transmission in the community.
Does A Person Still Require Wearing Masks After Infection?
Researchers stated that after recovering from the infection, the body develops natural immunity that can shield from further infection for at least five months. It is somewhat as effective as vaccination for this duration. Though the chance of reinfection is less it is not permitted to go without wearing a mask.
How Reinfected Cases Were Found In COVID-19 Recovered Patients?
SIREN is seen to be the largest study of coronavirus reinfection. It systematically screens for asymptomatic infections in people. When COVID infected and recovered patients went through this screening for the detection of the virus, they found 44 possible reinfections after five months.
Note that the people who participated in this study were females below the age of 60. This group was less likely to experience the severe type of COVID-19, and may not represent the entire population.
How COVID 19 Unlocked the Potential of RNA Vaccine?
All 44 cases of COVID-19 infection were seen to be reinfection
. They were categorized based on PCR tests along with screening measures. This was done to lessen the chances of re-identification of the virus from the initial stage of infection.
Researchers are still gathering data to learn more about how long does immunity last in a person. Further research is going to be performed to examine the impact of a SARS-CoV-2 variant “B.1.1.7” that evolved in 2020 and has quickly spread throughout the country.
Conclusion
Reinfection with the virus is still an open question. If we go by research, we have various reasons to say that COVID-19 infected people won’t get reinfected with it.
However, it is important to understand that the increase in immunity levels is effective for that variant and might not be adequate for new variants of COVID-19. This shows that people can still get infected with new mutations in the coronavirus.
