Fears of biggest UK outbreak in two decades as 2,793 cases confirmed in first quarter of 2024

The UK may be experiencing its biggest outbreak of whooping cough in two decades, with five deaths reported among infants who developed the disease in England between January and March.

According to the latest data published by the UK Health Security Agency (UKHSA) on Thursday, cases of whooping cough continue to increase, with 1,319 confirmed in March. This brings the total number of confirmed cases during the first quarter of 2024 to 2,793. The true number of cases is likely to be much higher though, because mild cases are easily confused with other respiratory illnesses in the early stages when the infection can be tested for.
