During week 44, across syndromic surveillance systems acute respiratory infection indicators were in general stable and in line with expected seasonal levels, but with increased activity noted in children aged 1 to 4 years. Influenza-like illness (ILI) indicators remained above seasonally expected levels, with emergency department ILI attendances continuing to increase in the 1 to 4 and 15 to 44 years age groups, with smaller increases observed in adults aged 45 years and over.
Remote health advice syndromic surveillance system
During week 44, NHS 111 triaged calls for acute respiratory infections (ARI) remained stable overall and within expected levels for the time of year. ARI calls decreased slightly in children aged 5 to 14 years while there was a small increase in children aged under 1 year; other age groups remained stable.
Note: NHS 111 online assessment data were not available for 29 October due to a technical issue. We are working with the data provider to restore data in the next future bulletin. Consequently, recent trends for NHS 111 online assessments should be interpreted with caution.
