Covid infections are rising as colder weather arrives, with data from the UK Health Security Agency showing a 60% rise in the hospitalisation rate since the end of August. The new XFG variant is now dominant in the UK, although health chiefs have stressed there is no evidence it causes more severe disease. Millions of people are being urged to come forward for free Covid and flu vaccinations before winter.
But colder months also bring a surge in other respiratory viruses, so how can you tell the difference? Dr Hana Patel, a GP working with Superdrug Online Doctor, told the Express: “Telling the difference between flu and Covid can be really tricky, because many of the symptoms overlap. The only way to know for certain is, of course, by taking a test. That being said, there are some subtle differences to watch out for.”
A sudden loss or change in sense of taste and smell is much more common with Covid than flu or a cold, Dr Patel said.
Covid “can also cause shortness of breath, lingering fatigue, and muscle aches that last longer than you’d expect”, she added.
Flu also typically comes on very suddenly, she said. “One day you feel fine, the next you’re hit with a high temperature, chills, headaches, and body aches. People often describe it as being ‘wiped out’ almost instantly.
“Colds, on the other hand, are generally milder. They tend to stay ‘above the neck’ with a runny or blocked nose, sneezing, and a sore throat, but you don’t usually get the extreme fatigue, fever, or body aches you’d expect from flu or Covid.”
Dr Patel said both flu and Covid can make you “very unwell” and pose a more serious risk to vulnerable groups including elderly people.
She added: “This winter we’re likely to see both viruses circulating at the same time, which increases the risk of pressure on healthcare and of catching one while you’re still recovering from the other.
“The good news is that vaccines, good hygiene, and sensible precautions can go a long way in reducing risk.”
The GP urged people to take simple steps that can make a big difference. She said: “Keeping up to date with flu and Covid vaccines is one of the most effective ways to protect yourself.
“Washing your hands regularly, covering coughs and sneezes, and staying home if you feel unwell all help to reduce the spread.
“If you’re in busy indoor spaces, wearing a mask can add an extra layer of protection. These small habits not only protect you but also help keep vulnerable people safe.”
