Introduction: Scrub typhus is one of the most underreported and fatal illnesses accounting for 23% of all febrile illness. Rajasthan reported cases during 2018-2019 in state reporting system but did not report any case to central Integrated Disease Surveillance Programme (IDSP) unit. We evaluated the Scrub typhus surveillance system in Alwar district, Rajasthan, with the objective of describing and evaluating the system and providing evidence-based recommendations to identify gaps.
Material and methods: In cross-sectional study, we reviewed records and conducted key informant interviews at district- and block-level health facilities. Using US Centers for Disease Control guidelines, we evaluated the system by framing indicators for selected attributes for a defined reference period. Overall performance was ranked as outstanding (90-100%), excellent (80-89%), very good (70-79%), good (60-69%), and poor (<60%).
Results: Line list of confirmed cases was sent from district to block level for additional active case search (ACS) to implement control measures. We conducted 26 key informant interviews and reviewed records and calculated simplicity as 79%, flexibility 100%, data quality 46%, acceptability 92%, representativeness 48%, timeliness 43%, and stability 79%.
Conclusions: Epidemiological surveillance (active and passive) is a core intervention under scrub typhus surveillance system. Lab reports were incompletely uploaded on IDSP portal. Surveillance reports should be updated after each ACS. Reporting format under IDSP should be uploaded timely, and lab reports from state should be sent within 48 hours of diagnosis so that case investigation is not delayed.
