SARS-CoV-2 (a.k.a. COVID-19) is still a workplace illness risk thanks to summer-like temperatures predicted to carry well into the fall season.
While the colds and flu are more seasonal, the threat of COVID-19 remains in warm to hot climates. Here's why.
COVID-19 Resurgence in Summer-Like Climates: What the Data Shows
COVID-19 Resurgence in Summer-Like Climates: What the Data Shows
Recent data from the Centers for Disease Control and Prevention (CDC) indicates that COVID-19 cases are rising again in 44 states. This uptick in cases isn't just a seasonal blip—emergency room visits and hospitalizations related to COVID-19 have also seen an increase despite remaining lower than the pandemic's peak.
Even deaths, which had dropped to their lowest levels since the pandemic began, are starting to inch upward again. This resurgence is an immediate reminder that COVID-19, though less dominant in the headlines, is still very much with us.
Meet the FLiRT Variants: The Drivers of COVID-19 Cases in Summer-Like Temperatures
Unlike the flu, which tends to disappear during the warm months of summer-like climates, COVID-19 has shown a tendency to linger. The latest culprit behind this persistence? A new set of variants collectively known as FLiRT. These variants—KP.3, KP.2, and KP.1.1—make up a significant portion of current COVID-19 cases in the U.S., with LB.1, another related strain, contributing to the case numbers. The FLiRT variants belong to the Omicron family, known for its high transmissibility. This means they spread easily, even among populations that might have some immunity from previous infections or vaccinations.
Why FLiRT Variants Matter
One of the concerning aspects of the FLiRT variants is their genetic makeup. These strains are more "distant" from their predecessors, meaning the immunity people gained from earlier infections or vaccines might not fully protect against them. While vaccination remains an essential tool in preventing severe disease, the evolving nature of these variants means staying up to date with vaccines is crucial.
The U.S. Food and Drug Administration (FDA) has already recommended that the next round of COVID-19 vaccines target the KP.2 FLiRT strain. The CDC advises that everyone aged six months and older receive the updated vaccine once it becomes available to help ward off severe illness.
Advice for Older Adults and Vulnerable Populations
Although experts don't anticipate a dramatic surge like the early days of the pandemic, even smaller spikes in COVID-19 cases can have significant impacts, especially on vulnerable populations. Older adults and those with underlying health conditions remain at higher risk for severe outcomes if they contract the virus.
Health officials strongly recommend that individuals in these groups get an additional dose of the COVID-19 vaccine if they haven't done so already. This booster will provide the best protection until the vaccines are updated again in the fall. If you also catch COVID-19, consult your doctor about available treatment options. Some prescription medications can help mitigate the severity of symptoms if taken early.
Summer-Like Temperatures and COVID-19: A Mixed Bag
Many people assume summer-like climates are safer for COVID-19 because of outdoor activities. However, summer-like temperatures also bring unique risks. Travel increases and sweltering temperatures often drive people indoors, where air-conditioning can create environments conducive to viral spread.
It's important to remain vigilant and remember that COVID-19 isn't going away. It’s now a part of our environment, and we need to continue taking it seriously to protect ourselves and those around us.
If you’re managing disease spread in the workplace based on symptoms, it’s too late. People are contagious whether or not they appear ill. Don't let one sick employee infect ten more. Minimize disease spread with the New Wello Protocol from Wello AI.
