RESUMEN
Acute undifferentiated febrile illness (AUFI) constitutes the predominant cause of healthcare seeking in Odisha. This prospective study was conducted to analyse the clinical, epidemiological and laboratory profile of scrub typhus patients presenting with AUFI from January to December 2017. Four hundred and thirty-two samples were tested for dengue, malaria, scrub typhus and enteric fever. Scrub typhus was overall the most common cause of AUFI (26.3%, 114/432) followed by dengue (19.2%, 83/432). Eschar was seen in 6.1% of cases. Aetiologies of 38.6% of AUFI remained unidentified. In the present study, there was no mortality attributed to scrub typhus.
RESUMEN
The surveillance in Chennai identified 134 children and 443 adults clinically suspected for leptospirosis. Of these, 35 (26.1%) children and 118 (26.6%) adults had laboratory confirmed diagnosis for leptospirosis. The paediatric leptospirosis exhibited a higher frequency of classic features of Weil’s disease. The prevalent serovar encountered was Icterohaemorrhagiae with no difference in the pattern of infecting serovars between the two groups. Further, confirmation of diagnosis was achieved by polymerase chain reaction (PCR) with a positivity of 28.4% (specificity 96%). Univariate analysis showed significant association of paediatric leptospirosis with rat infestation (odds ratio 87.4). Thus, PCR facilitates early diagnosis of febrile illness among paediatric cases.
