During week 32, GP out-of-hours daily contacts for gastroenteritis and diarrhoea increased. Daily contacts for fever also increased.
Please note: trends for week 32 should be interpreted with caution. We are investigating a potential change in coding practice by one GP out-of-hours service provider during week 32 which may have impacted on national trends, causing small increases in some syndromic indicators.
