A TWO-YEAR EPIDEMIOLOGICAL STUDY ON ENTERIC FEVER CAUSED BY SALMONELLA SP FROM TAMIL NADU, SOUTH INDIAK. RAVIKUMAR., M. MANI, K. RAJADURAIPANDI, K. PANNEER SELVAM, ANJALI SUSAN PHILIP, AND IW. RAJASREE
This study analyses the prevalence, demography and seasonal variation of enteric fever caused by Salmonella sp. A retrospective review of all cases reported for diagnosis with suspected enteric fever at a diagnostic center was carried out for screening patients with confirmed enteric fever. All the patients' records were further analyzed for microbiological and serological details. Cases with culture proven and significant serum titer upon WIDAL test were included for epidemiological analysis. Of the 1023 patients, who attended the diagnostic center, 373 (36.4%) patients were found to be positive for enteric fever. 228 and 145 cases were male and female respectively. Salmonella lyphi was found to be the predominant (290) causative agent. Peak period of disease spread was noticed, as the number of cases was not uniform throughout the year. This study emphasizes the importance of adequate surveillance for this pathogen by the epidemiologists as well as on the need for creating awareness among public to adopt proper sanitary measures by the health care providers so as to lessen transmission of this pathogen.
