As of mid-August 2024, several COVID-19 variants are making headlines, notably the FLiRT family of strains and the emerging LB.1 variant. According to recent data from the Centers for Disease Control and Prevention (CDC), the KP.3.1.1 strain from the FLiRT family has become the most prevalent, responsible for approximately 27.8% of all cases. Conversely, LB.1 is currently estimated to account for 16% of infections.
Dr. Tammy Lundstrom, a senior vice president at Trinity Health, noted that while FLiRT variants began to appear prominently in March, they share similar symptoms with previous COVID-19 strains. Symptoms to watch for include a chronic cough, sore throat, runny nose, fever, and fatigue. As the summer continues, experts are observing a resurgence in cases, partly due to increased travel and gatherings associated with the season.
Dr. Nikhil K. Bhayani, an infectious disease specialist, elaborated on the FLiRT variants, which include KP.2, KP.2.3, KP.3, and KP.3.1.1, all classified under the FLiRT umbrella. These variants have outpaced earlier strains but do not appear to cause more severe illness compared to their predecessors. Unfortunately, only 22.5% of American adults had received the latest COVID-19 vaccine by May 2024, raising concerns about vulnerability during this uptick in cases.
In terms of treatment and prevention, experts affirm that COVID-19 vaccines remain effective against severe illness. A new vaccine is expected for the 2024-25 season, specifically targeting the most common circulating variants. Dr. Lundstrom advises that heightened protection measures—such as frequent handwashing, avoiding large crowds, and staying home when sick—should continue to be practiced.
As the CDC’s latest guidelines indicate, while COVID-19 still poses a risk, it is increasingly likened to other respiratory viruses. Individuals, particularly older adults and those with compromised immune systems, are encouraged to remain vigilant in taking precautions to safeguard their health.
This summer surge serves as a reminder of the ongoing challenges posed by COVID-19, highlighting the importance of vaccination and public health measures in combating its spread.
