During week 12 (ending 25 March 2018), influenza continues to circulate but decreases are noted across most indicators. Influenza A and B are co-circulating. The Department of Health has issued an alert on the prescription of antiviral medicines by GPs.

1.3 Syndromic surveillance

GP consultations for scarlet fever continue to increase and are above seasonally expected levels.

1.4 Norovirus

Since week 27, 2017 there have been 4,807 laboratory reports of norovirus in England and Wales. This is comparable to the average number for the same period in the previous 5 seasons from season 2012 to 2013 to season 2016 to 2017 (4,872).

Reports of suspected and confirmed outbreaks of norovirus in hospitals in England are currently at lower levels than in previous years (2012 to 2017).

1.5 Rotavirus

Since week 27, 2017, there have been 939 laboratory reports of rotavirus in England and Wales. This is 54% lower than the average for 2013 to 2014, to 2016 to 2017 (2,046) (the period after vaccine was introduced).

Following the introduction of the rotavirus vaccine into the routine childhood immunisation schedule in July 2013, the total number of laboratory-confirmed rotavirus infections each season has remained low compared to the pre-vaccine period.

1.6 All-cause mortality

During week 12, 2018, no statistically significant excess all-cause mortality by week of death was seen overall and by age group in England, through the EuroMOMO algorithm.
