Scarlet fever cases are now eight times higher than the last infectious season, according to official figures.
While the number of scarlet fever infections has started to fall, the UK Health Security Agency (UKHSA) warns the Strep A bacteria that causes the infection is "still circulating at high levels".
According to a recent report in the Mirror, there were 37,068 notifications of scarlet fever between September and January 8, compared with 4,490 at the same point in the year during the last time instances were comparably high, five years ago, in 2017-2018.
