The incidence of acute gastroenteritis and self suspected food poisoning in general practice populations was compared with consultation rates in four group practices during a 3-month winter period and a 2-month autumn period. The average monthly consultation rate for acute gastroenteritis and self suspected food poisoning was 0.3% and 0.06% respectively. However, over the same period, on average, an estimated 7% of the practice population per month reported an acute gastroenteritis illness, and 0.7% suspected a food poisoning illness. Only about one in 26 people who suffer an acute episode of gastroenteritis consult their general practitioner (GP). In two practices, faecal samples were sought from all patient cases; the isolation rate for salmonellas was 2% (3/191) and for campylobacters it was 12% (23/191). In the other two practices following routine management, the isolation rate for salmonellas was 9% (6/64) and for campylobacters it was 2% (1/64). Isolation of faecal pathogens was not associated with patients' suspicion of food poisoning. A history of eating out in the week before onset was associated with a significantly increased yield of salmonellas and campylobacters.
在三个月的冬季和两个月的秋季期间，将普通执业人群中急性肠胃炎和自我怀疑食物中毒的发病率与四家联合诊所的咨询率进行了比较。急性肠胃炎和自我怀疑食物中毒的平均每月咨询率分别为0.3%和0.06%。然而，在同一时期，平均每月估计有7%的诊所人群报告患有急性肠胃炎，0.7%怀疑患有食物中毒。每26名患急性肠胃炎的人中只有约1人会咨询他们的全科医生（GP）。在两家诊所，对所有患者病例都采集了粪便样本；沙门氏菌的分离率为2%（3/191），弯曲杆菌的分离率为12%（23/191）。在另外两家诊所进行常规管理后，沙门氏菌的分离率为9%（6/64），弯曲杆菌的分离率为2%（1/64）。粪便病原体的分离与患者对食物中毒的怀疑无关。发病前一周外出就餐史与沙门氏菌和弯曲杆菌的检出率显著增加有关。
