Covid Variants Stratus (XFB) and Nimbus (NB.1.8.1): What You Need to Know
New Covid-19 variants—Stratus and Nimbus—are spreading across the UK and US, causing a rise in infections. Common symptoms include a sore, croaky voice and a “razor blade” sore throat, alongside headaches, fatigue, cough, and nasal congestion. While these variants spread more easily due to genetic mutations, health experts confirm they are no more dangerous than earlier strains.
Current Situation:
-
UK: Covid positivity rates increased from 7.6% to 8.4% in one week. Hospital admissions also rose slightly. The government has launched a winter vaccination campaign promoting Covid and flu shots.
-
US: Covid levels in wastewater, a key indicator of spread, are moderate overall, but four states—mainly in the Northeast—report very high levels.
Symptoms to Watch For:
-
Sore, croaky throat (sometimes described as feeling like razor blades)
-
Headaches
-
Fatigue
-
Coughing
-
Runny or blocked nose
Public Health Guidance:
-
Stay home if you feel unwell or have a fever.
-
Avoid contact with vulnerable groups like the elderly or immunocompromised.
-
Wear a mask if you must go out.
-
Covid tests are no longer free on the NHS but available for purchase.
Vaccination Updates:
-
Boosters recommended for over-75s, care home residents, and immunocompromised individuals.
-
Pregnant women, children, and toddlers (for flu nasal spray) are also eligible.
-
Some pharmacies offer private Covid vaccines.
Regarding Vaccine and Cancer Concerns:
A recent South Korean study suggesting vaccines might raise cancer risk has been widely criticized by experts as misleading and unsupported by evidence.
Bottom Line:
The new variants are more contagious but not more severe. Staying informed, following health guidelines, and keeping vaccinations up to date remain the best defenses. Awareness—not alarm—is key.
