Reinfections of Covid-19 are 90 per cent less likely to result in hospitalisation or death than primary infection, a new study suggests.
Scientists from Qatar found that it is rare for people to be reinfected with the virus. And when an individual does catch Covid for a second time, the disease is generally mild in nature, the researchers said.
Out of 353,326 people who tested positive in Qatar between February 2020 and April 2021, a total of 1,304 reinfections were identified. The analysis excluded 87,547 people who were vaccinated.
Just four of the reinfections were severe enough to lead to acute care hospitalisation. None required ICU admission, nor did any end in death. Among the primary infections, 28 people were admitted to an ICU, while seven died.
The study, published in the New England Journal of Medicine, concluded that reinfections were not only milder than the initial infection, but far less likely to lead to hospitalisation or death.
