People who recovered from COVID-19 are at little risk of contracting the disease again, according to a study published this week.
Researchers in Qatar examined a cohort of over 353,000 people using national databases that contain information about patients with polymerase-chain-reaction-confirmed infections.
The studied population contracted COVID-19, the disease caused by the CCP (Chinese Communist Party) virus, between Feb. 28, 2020, and April 28, 2021.
Reinfections were counted if a person tested positive at least 90 days after their first infection.
After excluding approximately 87,500 people with a vaccination record, researchers found those with immunity from having recovered from COVID-19 had little risk of reinfection and severe cases of the disease.
Just 1,304 reinfections were identified. That means 0.4 percent of people with natural immunity and without a vaccination record got COVID-19 a second time.
No cases of death were recorded among those who got infected a second time.
The study was published in the New England Journal of Medicine. It was funded by Weill Cornell Medicine–Qatar, Qatar’s Ministry of Public Health, the Hamad Medical Corporation, and Sidra Medicine.
