New COVID-19 Variants BA.2.86 and RF.5 Emerge
Scientists have found two new types of COVID-19 called BA.2.86 and RF.5.
RF.5 is special because it's made when two different types of the virus mix together.
Doctors are watching these new types closely because they might spread differently or be harder to fight with vaccines.
But don't worry, these new types are still part of the Omicron family, which usually causes milder sickness than the earlier types of COVID-19.
New COVID-19 variants BA.2.86 and RF.5 have emerged.
RF.5 is a recombinant variant formed by genetic material exchange.
Doctors monitor recombinant variants closely for potential changes in transmission or immune escape.
Both variants are part of the Omicron family, associated with milder disease.
The behavior of these variants is still being studied.
