The researchers have found that there was a higher risk of hospitalisation, lasting health complications after every reinfection by the virus, regardless of the person's vaccination status. In a statement the authors said, “Risks were lowest in people with one infection, increased in people with two infections, and highest in people with three or more infections.”
The study findings have highlighted that continued vigilance is necessary for people infected with COVID-19 to reduce the overall health risk. Additionally, studies have gathered data which confirms that the risk of reinfection is higher with the SARS-CoV-2 Omicron variant.
