A cross-sectional study of characteristics and risk factors associated with sporadic Campylobacter in Cardiff, the Vale and Bridgend 2017
MetadataShow full item record
Campylobacter is the most common cause of bacterial gastroenteritis in the UK, often attributed to exposure from contaminated poultry. Campylobacter can be acquired through both food-borne and environmental exposures inside and outside the home. This study aims to identify the characteristics and common risk factors associated with Campylobacter in Cardiff, the Vale and Bridgend. All cases in these local authorities are reported to Shared Regulatory Services (SRS) and contacted for an interview/questionnaire asking a series of questions to determine possible exposures during the incubation period. Existing data were gathered using standardised exposure report questionnaires for all cases notified to SRS from January to June 2017. Data from each case questionnaire was extracted and entered, analysed and cleaned using Epi InfoTM 3.5.1. The questionnaire provides information regarding demographic characteristics, travel, food history, domestic poultry preparation, environmental exposures and most likely exposure type. 340 cases met the case definition. Over half of the notified cases were from the Cardiff local authority and over half were male. Campylobacter infection was most common among the 65+ age category. The most common likely exposure type was food from the home, followed by food outside the home. In particular, domestic poultry cosumption was a risk factor for 70.46% of cases. Over half of cases reported animal contact during the incubation period which was the most common environmental risk factor. Several limitations were identified with the study design and methodology which must be considered when interpreting results. The study highlights the importance of thorough investigation into each case to identify common risk factors and target areas for intervention and advice. The study recommends domestic poultry preparation to be the target for improvement in these local authorities. Further research is needed to determine the accurate extent to which these risk factors are an issue.
