The FLiRT variants, which also include KP.2's "parental" lineage JN.1, have three key mutations on their spike protein that could help them evade antibodies, according to Johns Hopkins University.
Feline coronavirus is typically shed in feces by healthy cats, and transmitted by the fecal-oral route to other cats. [3] In environments with multiple cats, the transmission rate is much higher compared to single-cat environments. [2] The virus is insignificant until mutations cause it to be transformed from FECV to FIPV. [2]
The new "FLiRT" COVID-19 variants, including KP.3 and KP.2, are spreading in the United States. ... During a two-week period ending on June 8, KP.3 made up an estimated 25% of cases in the U.S ...
The previous COVID variant to watch was JN.1, which surged over the winter months and currently makes up 22% of COVID cases in the same two-week period. Other JN variants added up to 41% of all U ...
The most successful FLiRT variant so far is known as KP.2 and is starting to be seen more frequently as a cause of COVID-19. These mutations have been seen before, in different variants, they are ...
In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host. While latent or latency period may be synonymous, a distinction is sometimes made whereby the latent period is defined as the time from infection to infectiousness. Which ...
The JN.1 variant, which spread globally over the winter, made up 22% of COVID-19 cases in the U.S. in the same two-week span. KP.1.1, another FLiRT variant that is circulating, made up about 7.5% ...
FCoV is a virus of the gastrointestinal tract. Most infections are either asymptomatic or cause diarrhea, especially in kittens, as maternally derived antibody wanes at between 5 and 7 weeks of age. The virus is a mutation of feline enteric coronavirus (FECV).
