Physical environments of water containers and Aedes sp larvae in dengue endemic areas of Tanjungpinang Timur District

Purpose: This study aimed to determine the relationship of container environment's type and condition existence Aedes sp larvae in Tanjungpinang Timur District. Methods: An observational with a cross-sectional approach involved 401 houses containers District, City. Data on was performed using single method. environmental conditions (water pH, water temperature, air humidity) larvae's presence were collected by observing measuring. Results: 863 observed, 138 them (15.99%) found sp, inside house (65.57%), not closed (88.53%). The types controllable sites (95.13%), disposable (3.36%), under (1.51%). measurement pH (76.13%) temperature (82.73%) categorized as good. Container 98.38% showed results range unfavorable (<200C &> 300C) humidity 99.07% (<81.5% 89.5%). Type, location, closure, related District (p-value <0.05), while variable larvae. Conclusion: Physical factors strongly support reproduction DHF vectors East It is necessary increase public knowledge routine home eradication mosquito nests (PSN), especially site widely used reservoirs.
