What Arizonans Need to Know About the FLiRT COVID-19 Variants
A new set of COVID-19 subvariants known as FLiRT has been on the rise, sparking concerns among health experts. FLiRT strains are descendants of the omicron variant, with mutations in the spike protein of the virus earning them their nickname.
Despite the increase in prevalence, experts are not expecting FLiRT strains to cause more serious illness than previous versions of the virus. The Centers for Disease Control and Prevention (CDC) has been closely monitoring the FLiRT subvariants KP.2 and KP.1.1, which have been detected in a couple of instances in Arizona.
Current data suggests that there are low levels of transmission of FLiRT strains in the US. However, there is not enough evidence to determine if these variants will lead to a summer surge of COVID-19. The virus is known to be evolving by making minor tweaks to the spike protein to evade antibodies, leading to the emergence of new subvariants like FLiRT periodically.
Experts compare the subvariants of omicron to the “Fast & Furious” franchise, with new sequels appearing periodically. Despite the ongoing evolution of the virus, health officials remind the public to continue following safety measures such as wearing masks and practicing social distancing.
