FLiRT COVID-19 Strains Spread Widely, CDC Finds

FLiRT COVID-19 variants surge in the US

United States: According to the most recent statistics from the Centers for Disease Control and Prevention, several FLiRT COVID-19 variations are becoming more prevalent in the United States and this could lead to another outbreak as this seems very dangerous.

However, information made public by health officials thus far points to no cause for concern.

Rising Prevalence

Based on CDC estimates provided on Friday, almost 28% of new infections in the past two weeks were caused by KP.2, the most common variant circulating in the United States. That is an increase from almost 20% the previous two weeks.

About 13% of new coronavirus cases were caused by KP.3, another FLiRT variant and JN.1 descendant. This is a significant increase from the earlier estimate of about 8%.

When combined, KP.2 and KP.3 were thought to be in charge of over 2 out of every 5 new infections in the preceding weeks. It doesn’t currently appear that the FLiRT COVID-19 strains cause any novel or distinctive symptoms. Runny nose, sore throat, fever, and cough are typical COVID-19 symptoms.


Vaccine Hesitancy

COVID-19According to CDC data, less than 23% of adults rolled up their sleeves for the most recent updated shot, which was not as widely anticipated as the 19 vaccines that are projected to be effective against the strains.

FLiRT Classification

The precise nomenclature for these mutations gave rise to the moniker FLiRT for this set of COVID-19 strains. This month, the World Health Organization classified KP.2 and KP.3 as “variants under monitoring.” The term “variants under monitoring” indicates to public health officials that a variant of SARS-CoV-2 would need special attention and observation.



The World Health Organization states that the primary goal of this category is to determine whether this variant and those that are closely related to it “may pose an additional threat to global public health as compared to other circulating variants.”

Global Concerns


Globally, KP.2 and KP.3 are also rising, a WHO report states.

Thus far, it doesn’t seem that the strains are responsible for a rise in COVID-19 health indicators in the United States, such as hospitalizations or fatalities. Hospitalizations for COVID-19 have lately fallen to their lowest point since the pandemic started. Additionally, the CDC reports that nationwide wastewater virus activity is currently “minimal,” which can be used to track both symptomatic and asymptomatic infections.

Future Vaccination Strategy


According to the CDC, “KP.2 is the predominant variant in the U.S. but isn’t causing an increase in COVID-19 infections or more severe illness than other variants.”

The next wave of COVID-19 vaccinations and the strain or strains that should be targeted will be discussed at a meeting in June by CDC vaccine advisers.
