Reporting week 14: 30 March to 5 April 2026
During week 14, most syndromic surveillance indicators showed largely stable or improving patterns, with some expected variation in healthcare seeking behaviour associated with the 2 national Bank Holidays at Easter. Most respiratory indicators were stable or decreasing, although GP in-hours consultations for acute bronchitis continued to increase slowly.
Note: some of the observed increases in syndromic indicators reported during week 12 may reflect changes in healthcare seeking behaviour linked with public health messaging during the invasive meningococcal disease outbreak in South East England. During week 14, healthcare seeking behaviour patterns may have changed due to different availability during the National Bank Holidays during Easter, so trends should be interpreted with caution.
Remote health advice syndromic surveillance system
During week 14, total NHS 111 triaged calls and online assessments increased over the Easter bank holiday weekend (Friday 3 to Monday 6 April), in line with the expected increase in activity during a public holiday. Activity and trends during this period should therefore be interpreted with caution.
NHS 111 acute respiratory infection triaged calls and online assessments both remained stable and were below or similar to seasonally expected levels respectively. Diarrhoea and vomiting indicators showed no overall trend. Triaged calls for eye problems increased, particularly among those aged 5 years and over, and remained above expected levels.

GP in-hours syndromic surveillance system
During week 14, GP in-hours consultation rates across a number of acute respiratory infection indicators decreased, although acute bronchitis continued to increase slowly. Gastroenteritis indicators (including diarrhoea and vomiting) decreased but remained above expected levels. Allergic rhinitis consultations decreased and were just above expected levels associated with seasonal tree pollen activity.
