The number of children who have died from invasive Strep A illness in the UK has risen to 15, health officials have confirmed.
The UK Health Security Agency (UKHSA) has recorded 13 fatalities linked to the bacterial infection in England, while one child has died in Northern Ireland and another in Wales.
Group A strep bacteria can cause many different infections, ranging from minor illnesses to deadly diseases.
Illnesses caused by Strep A include skin infection impetigo, scarlet fever and strep throat.
While the majority of infections are relatively mild, sometimes the bacteria cause a life-threatening illness called invasive Group A Streptococcal disease.
The UKHSA has said there was no evidence that a new strain is circulating and the rise in cases is most likely due to high amounts of circulating bacteria and increased social mixing.
It comes as pharmacists continue to use Twitter to complain of shortages in access to antibiotics, including the liquid version of penicillin, which is given to children.
It comes as health authorities last night confirmed the death of a four-year-old with Strep A from Ireland just hours after news broke that two children were admitted to hospital following a scarlet fever outbreak at a primary school in Wales.
It follows official data published yesterday that revealed scarlet fever cases have surged by tenfold in a year.
UKHSA figures showed a huge rise in scarlet fever cases in England and Wales from last year, with 23,000 cases in the year to date, compared to just 2,300 for the same period in 2021.
Infections for the final half of the year were also more than three times higher than the average for the previous five years.
Scarlet fever usually only causes mild illness with symptoms such as a fever and rash. Early treatment with antibiotics is important to reduce the risk of complications such as pneumonia or a bloodstream infection.
