It is possible to catch Covid repeatedly within a short time period. Covid variants and sub-variants continue to emerge, causing a resurgence of coronavirus cases.
After catching Covid your body’s immune response helps fight off the virus. However, scientists are still unsure how long this protection lasts.
Data from the Office of National Statistics (ONS) suggests that people are more likely to be reinfected with the Omicron variant. ONS found that reinfections were ten times higher when Omicron became the dominant variant, between December 2021 and March of this year, than during the period that Delta was most common.
