ENDEMIOTY OF ZOONOTIC DISEASES OF PORCINE ORIGIN IN LAO PEOPLE'SDEMOCRATIC REPUBLIC: IDENTIFYING SOCIO-CULTURAL RISK FACTORSTHROUGH MULTIPLE CORRESPONDENCE ANALYSIS

摘要

The aim of this study was to identify potential risk factors for human infection with zoonotic diseases of porcine origin in Lao PDR. Multiple correspondence analysis was performed on data collected during a large cross-sectional study regarding pig contact, consumption of pork products, hygiene and sanitation. Cluster analysis was then conducted to aggregate individuals into relatively homogeneous subgroups. The analysis identified three distinct profiles: cluster 1 had low pig contact and good hygiene practices and were used as the baseline category for subsequent risk factor analysis. Individuals' in cluster 2 were more likely to have occupational pig contact (handling and slaughtering pigs) and had increased odds of testing seropositive for hepatitis E and Japanese encephalitis. Cluster 3 had poorer sanitation and hygiene and had increased odds of testing seropositive for hepatitis E and cysticercosis/taeniasis. The results of this study could be used to conduct risk-based surveillance and control activities.
