New COVID Strain or Lingering Cold? Key Differences Every Brit Should Know
As coughs echo through workplaces and sneezes punctuate train commutes, Brits are grappling with a pressing question: Is this lingering misery just a stubborn cold or something more concerning?
Health experts warn the latest COVID-19 variant—JN.1—is circulating alongside typical seasonal illnesses, creating what epidemiologists call a "dual-demic." Unlike common colds that primarily affect the upper airways, this coronavirus strain tends to dig deeper into the respiratory system, often causing prolonged fatigue and persistent coughs.
"Patients describe COVID as settling like a heavy weight in their chest," says Dr. Fiona Harper, a London-based GP. "We're seeing it typically lasting 10-14 days, compared to the 5-7 day trajectory of most winter colds."
Why This Matters Now
With NHS waiting rooms filling up, understanding the difference could help families:
- Protect vulnerable loved ones (early COVID detection prevents spread to elderly relatives)
- Access appropriate treatment (antivirals like Paxlovid work best when taken early)
- Plan work/school absences realistically
The Telltale Clues
While symptoms overlap considerably, three biomarkers help distinguish the viruses:
- Loss of taste/smell remains more common with COVID (reported in 65% of JN.1 cases vs. <10% of colds)
- Temperature spikes (over 38°C) occur in 78% of COVID cases versus 35% of colds
- Body aches feel more intense and widespread with COVID (according to symptom-tracking ZOE app data)
Staying Protected
Free booster shots remain available at pharmacies through December for:
- Over 50s
- Frontline health workers
- Immunocompromised individuals
"Don't write off that tickle in your throat," advises Dr. Harper. "Testing remains crucial—especially before visiting grandparents or attending holiday gatherings." With home test kits available at most pharmacies (£9.50 for pack of 5), experts emphasize early detection as key to limiting spread.
