Reporting week 3: 13 January to 19 January
During week 3, the previous decreasing trend in patient contacts for acute respiratory infections and respiratory indicators stabilised, broadly due to increases in contacts for children aged 1 to 14 years. The previously decreasing trend in emergency department (ED) attendances for influenza-like illness ended, with the all-age, overall trend stabilising across the week, driven by increases in child age groups, particularly school aged children 5 to 14 years.
Remote health advice syndromic surveillance system
During week 3, the previous decrease in NHS 111-triaged calls and online assessments for acute respiratory infections stabilised, due to increases in calls for children (1 to 14 years for calls, 5 to 14 years online). NHS 111-triaged calls and online assessments for vomiting also increased, with increased calls for child age groups (0 to 14 years) and increased online assessments for adult age groups (45 years and over).

There was also a decrease in the rate of influenza-like illness nationally, however consultation rates for children 1 to 14 years were stable, rather than a decreasing trend. GP in-hours consultations for pneumonia decreased.

Emergency department syndromic surveillance system
During week 3 the previously decreasing trend in ED attendances for acute respiratory infections and influenza-like illness ended, with now stable attendance numbers across the week due to increases in child age groups, particularly school aged children 5 to 14 years. Attendances for acute bronchiolitis or bronchitis increased, primarily in children under 5 years of age, and asthma attendances increased, particularly in children 1 to 14 years.
