Many people are currently experiencing coughs, colds and flu-like symptoms, with viruses spreading rapidly as temperatures drop. But how can you tell whether it’s a common cold, Covid‑19, or the so-called “super flu” — a term used to describe a particularly severe or long-lasting influenza, rather than an official virus?
Medical doctor Dr Oscar Duke, a regular TV presenter including on BBC’s Morning Live, explains how to recognise the differences and reduce the risk of severe illness.
Why Are Viruses More Common in Winter?
The link between cold weather and immune function remains unclear. However, darker, colder days tend to push people indoors, where viruses can circulate more easily.
Schools and nurseries are hotspots for viral transmission, particularly after the summer holidays, as children bring germs home. University halls can have a similar effect, with close living conditions, social gatherings, and heavy drinking all contributing to weakened immune systems.
What Is “Super Flu”?
NHS officials have warned that the UK is facing an unusually early and severe flu season. This year, the influenza A(H3N2) strain has emerged earlier than normal and is considered more intense than usual, leading some to refer to it as “super flu.”
Despite the severity, current vaccines remain effective against this drifted strain. Public health advice continues to recommend vaccination, along with standard hygiene measures such as regular handwashing, covering coughs, and staying home when unwell.
