A ‘strange’ new symptom that only occurs at night has been linked to the latest sub-variant of Covid-19.

If you suffer from “night sweats,” it could be due to the BA.5 subvariant of the coronavirus.

Along with BA.4, these subvariants have now become the dominant strain of the virus worldwide.

An estimated 78.7% of confirmed cases in England are now BA.5, which was first identified in April and classified as a variant of concern on 18 May.

And according to at least one expert, night sweats occur as a result.

“An additional symptom of BA.5 that I saw this morning is night sweats,” Luke O’Neill, professor of biochemistry at Trinity College Dublin, told Irish radio station NewsTalk.

‘Isn’t that strange?’

According to Professor O’Neil, the appearance of various symptoms is due to our immune system responding to the genetic changes in the virus when new subvariants appear.

“The disease is a bit different because the virus has changed. There’s some immunity to it — obviously in the T-cells and so on,” O’Neill said.

“And that mix of your immune system and the virus being a little different could lead to a slightly different disease — with oddly enough — night sweats being a trait.”

We don’t yet have a lot of data on how common night sweats are as a symptom for most people.

The most commonly reported Covid-19 symptoms in vaccinated people to date include a runny nose, headache, sneezing, sore throat and persistent cough.

Other symptoms that were previously more prominent, such as loss of smell and fever, are now reported less frequently.

dr Meera Chand, Director of Clinical and Emerging Infections at the UK Health Agency, said: “We continue to monitor the emergence of new variants and assign them variant designations when they are sufficiently prominent to warrant a separate epidemiological and laboratory assessment.

“It is not unexpected to see new lineages and ongoing screening is a normal part of infectious disease surveillance.

“It’s important for everyone to ensure they are up to date with the vaccinations on offer as they remain our best form of defense against serious illness.”
