vomiting increased slightly and are currently above seasonally expected levels. NHS 111 calls for diarrhoea were stable but remain above expected levels.  Please note that recent updates to

the NHS Pathways clinical tool used by NHS 111 have affected the reported levels of certain syndromic indicators. As a result of these changes all individual respiratory indicators have been

removed from this report and replaced with a generic ‘acute respiratory infections’ calls indicator. Please see the bulletin for further information. Remote health advice syndromic
