The Existence of Mosquito Vectors in the Hospital Environment

Background: Indonesia has a tropical climate favorable for insect populations. Vector-borne diseases pose a significant threat. Mosquitoes are a major vector in the transmission of dengue fever, malaria, and Zika through their bites. This study aims to determine the presence of mosquito larvae in the hospital environment, considering physical factors and breeding characteristics as a preventive measure against the spread of vector-borne diseases. Methods: A descriptive cross-sectional design was chosen for this study. A purposive sample was taken at a hospital in Klaten Regency, Central Java Province. The observations were conducted from July to August 2025. Data obtained through observation, interviews, and laboratory tests are used to identify mosquito larvae. Results: The existence of mosquito larvae in the hospital was 28.6% of the observation sites, with adult mosquitoes found at all observation points. Physical and chemical vector control measures were implemented at all sites, while biological control measures were only implemented at one observation site. Conclusion: The existence of mosquito larvae in hospitals is high, more frequently found in locations with substandard temperature and lighting conditions, in cement containers, made from cement, with dark gray interior walls, and in containers without lids.
