An immunologist warned about a new strain Corona virus infection covid can be the cause of a variety of symptoms – including those that appear at night.
Omicron BA.5 is a highly contagious subvariant that is causing concern as it is contributing to a new wave of infections around the world, including in the UK.
Scientists find differences with previous strains, including with the ability to re-infect people within weeks of contracting Covid.
A leading immunologist has now suggested that this may be the cause of the new symptom in patients.
“One additional BA.5 symptom I saw this morning is night sweats,” Professor Luke O’Neill of Trinity College Dublin told an Irish radio station earlier this week.
“Isn’t that amazing?” he added.
BA.5 is causing a surge in cases in a number of countries along with BA.4, including Europe and Australia. This too became the dominant option in the US this week.
“The disease is slightly different because the virus has changed,” Professor O’Neill said Novostalek on Thursday.
He added: “There’s a certain immunity to it – obviously with T cells and so on – and that combination of your immune system and the virus being slightly different can cause a slightly different disease, oddly enough, night sweats is a feature.
“But it’s very important that if you’re vaccinated and you get rehabilitated, it doesn’t go into severe disease, that’s a message that people should be reminded of.”
BA.5 was first found in South Africa in February, one month after the identification of BA.4 in the same country. Both have since spread around the world and raised concerns about a resurgence of Covid infections.
Growth continued to be driven by Omicron’s BA.4 and BA.5 sub-variants, the spokesman said Office of National Statisticswhose latest figures show that 1 in 25 people in the England had Covid for the week ending June 29.
That equates to 2.7 million infections – an 18 percent increase from 2.3 million the previous week.
That’s the highest estimate since late April, but still below the record high of 4.9 million reached in late March.
