Background: To characterize malaria and assist in prevention efforts, we conducted a series of cross-sectional studies in Sundargarh district, India, in 2013-2014, where malaria prevalence among 1307 subjects was found to be 8.3% (Van Eijk et al, Sci Rep 2019; Study: India ICEMR Cross-sectional in ClinEpiDB). Using these data, villages were divided into low (<2%), medium (2-10%) and high (>10%) malaria prevalence, and risk factors assessed by type of village. Children and males were found to be at higher risk of malaria than older people and females. In 2017, we undertook a subsequent behavioral survey among 500 participants in 237 households of four of the medium and high malaria villages.

Objectives: Investigate the behavioral aspects of malaria risk.

Methodology:

Geographic Location/Study Sites: Odisha, India

Dates of Data Collection: February-May 2017

Study Design: Cross-sectional survey

Eligibility Criteria: Participants must have been aged 12 months to 69 years. Pregnant women were excluded.

Data Collection: In a published survey around Rourkela in 2013-2014 (N=1307), malaria prevalence was found to be 8.3%. Using these data, villages were divided into low (<2%), medium (2-10%) and high (>10%) malaria prevalence, and risk factors assessed by type of village. Our analyses showed that the rainy season and male gender were risk factors for malaria; in high malaria villages, young age was an additional risk factor, and indoor and outdoor spraying was protective compared to no spraying. We undertook a subsequent behavioral survey in four of the medium and high malaria villages in 2017 to investigate the behavioral aspects of malaria risk among 500 participants in 237 households. Participants were interviewed using a structured questionnaire with sections on malaria history and use of mosquito protection; blood was collected for microscopy, a rapid malaria test, and PCR testing.

ClinEpiDB Data Integration: Data files were provided to ClinEpiDB as flat csv files. Redundant or administrative columns were dropped from presentation on ClinEpiDB.org. All dates were obfuscated per participant through the application of a random number algorithm that shifted dates no more than seven days to comply with the ethical conduct of human subjects research.
