Abstract

Widal test is one of the diagnostic tools used to establish typhoid fever. However, the test may show false positive particularly among healthy individuals living in a poor sanitation environment. The aim of this study is to compare the titer of Widal test among healthy individuals living with good or poor sanitation. A total of 180 healthy individuals resided in Langsa City were enrolled in the study between March and May 2018. Sanitation status of each individual was recorded, assessed and classified into good or poor sanitation. Of these, 90 and 90 individuals were defined as having good and poor sanitation, respectively. The proportion of positive Widal titer on Salmonella typhi O was 66.7% (60/90) in individuals with good sanitation and 61.1% (55/90) among individuals with poor sanitation (P>0.05). However, conversion of S. Typhi H was more frequent among healthy individuals living with poor sanitation (OR 3.348, 95 % CI = 1.754-6.390). We conclude that the sanitation level increased the antibody titers in the Widal test, and therefore Widal test has limited use to diagnose typhoid fever. Further study is needed to evaluate behavioral risk factors associated with increased Widal titer and the cut-off level for Widal titer in population in Langsa City.
