COVID-19 Update
“Sorry to say, but it may be Covid-19- the virus which caused global lock downs in 2020 and 2021 is still sticking around — we just don’t hear about it as much these days” says one news article.
I am not sure we knocked out COVID. It appears to be mutating into new and improved replication machines every few months.
So, what is going on now?
What’s going on now: the “Stratus” / XFG variant surge
The COVID-19 variant called XFG, commonly nicknamed “Stratus,” is now emerging as a dominant strain in the U.S. and in other parts of the world. (Prevention). Some sources say it already accounts for as much as 78 % of U.S. cases. (Prevention). The variant is thought to be hybrid of two earlier Omicron strains (LF.7 and L. 8.1.2). According to wastewater surveillance, many states currently have “high” or “very high” prevalence of COVID-19 viral levels. (Prevention). Despite its rapid spread, health authorities such as the WHO and CDC currently classify XFG as a “variant under monitoring” (i.e. not yet elevated to “variant of concern”) and assess its public health risk as low. (The Independent). So far, there is no clear evidence that XFG causes more severe disease (hospitalizations, deaths, long COVID) than previous variants. (Stony Brook Medicine Health News)
Symptoms & what’s changing (or not)
Clinically, XFG’s symptoms largely overlap with those of previous SARS-CoV-2 variants. Symptoms include cough, fatigue, sore throat, fever or chills, congestion, headache, muscle aches, and occasionally loss of taste or smell. (Healthline). Another symptoms, hoarseness (a scratchy, raspy voice), is getting attention as a more prominent or early symptom in many cases of Stratus. Some sources argue it may be a sort of “calling card.” (The Independent)
Vaccines, immunity, and effectiveness
Because Stratus carries mutations in its spike protein, it has somewhat improved ability to evade antibodies generated from prior infection or vaccination. Even though antibody protection against mild infection might be reduced, cellular immunity (T-cells) and immune memory are still believed to still offer protection against severe disease, hospitalization, and death. (Healthline). The vaccines currently in use are being updated for the 2025-2026 formulation, which is intended to better match the circulating variants (including those related to XFG). (UCHealth). Some logistical challenges are emerging: not everyone may have access to or be willing to get the updated booster immediately, and in certain states or settings, you might need a prescription or face coverage limits. (UCHealth). A credible research study published in the Lancet showed that “Prior infection does improve immunity, meaning it gives a measurable shield against reinfection, especially in the months following infection.”. However, public health advice often emphasizes that those with lower immunity (elderly, immunocompromised, etc.) should discuss with their family and physician whether or not to get a booster. For lower-risk individuals, healthier individuals with healthy immune systems, a booster may not be of additional benefit especially in those who have had multiple episodes of SARS CoV-2 infections.
Takeaway & what you can do
If you’re experiencing respiratory symptoms now—particularly a hoarse voice included—you should at least test for COVID-19 (e.g. rapid antigen or PCR) and treat it like any recent COVID infection (isolate, rest, fluids, monitor and take vitamins and supplements to support your immune system).
Don’t assume a “cold” is harmless; mild cases can still spread, and vulnerable people around you could be at risk.
Maintain other protections too: good ventilation, masks in crowded indoor settings, hygiene, staying home when sick.
Above all, consult your personal physician or a trusted health professional who understands your risk profile and can help you weigh the benefits vs. downsides for you personally.
