The number of people falling ill with group A streptococcal infections, which include scarlet fever, is higher than normal and the rise in the number of cases has come earlier in the year than is usual.
The trend mirrors that of the UK during the same time, but the reason for the outbreaks remains unclear.
According to consultant microbiologist Dr Ivan Muscat, most Jersey cases have involved children aged under ten, and this year’s outbreak also began slightly earlier than in 2014 and 2015.
