Abstract


Background: Socio-demographic and environmental factors are associated with the malaria prevalence. Hence assessment of these factors would potentially help in identification of the possible risk factors among households with their health seeking behavior and would help to adopt the most suitable and appropriate malaria control strategies.

Methods: A baseline household survey was carried out in the study site Lingappayakadu, Mulki, Manglore involving all study population (n=4954) from July to September 2017. Total 1043 households were interviewed with predesigned semi- structured questionnaire with informed written consent. Blood samples were collected from fever cases and results were confirmed for malaria within 24 hours. Anti-malarial drugs including the Primiaquine were given to all the positive cases. Data regarding socio-demographic characteristics and health seeking behavior were also collected from study population.

Results: The prevalence of malaria in the study was 1.41% and slide positivity was 51.09%. The presence of malaria cases was statistically significant with number of members present in the family (p=0.00001, X2=199.37), age group (p=0.0168, X2=8.17) type of working status (p=0.0293, X2=7.06). Environmental factors like type of housing (p=0.3366, OR=1.3854), peri-domestic sanitation (p=0.1646, OR=0.554), Mosquito breeding (p=0.4504, OR=0.6757), indoor mosquitoes (p=1.000, OR=0.6173) and mosquito bite prevention methods were (p=0.1910, OR=1.7316) not showing any significant difference. Out of 137 fever cases, 70 cases were diagnosed with malaria amongst which 94.3% cases completed anti-malaria drug treatment.

Conclusions: A survey provides data regarding socio-demographic, environmental and health seeking behavior of population. The study did not show any statistically significant association of malaria with many environmental parameters. Health seeking behavior could be analyzed and improved with frequent surveillance methods.
