Seasonal variation of ovitrap index 誘蚊指數的季節性轉變
Dengue is an infection transmitted by mosquito bites. In Macao this mosquito is Aedes albopictus. Ovitrap Index is a marker for assessing mosquito growth, which in turn supports the evaluation of dengue risk in the population. The map shows the percentage of positive Ovitrap Index in Macao between March and December in 2006. Data for January and February are not shown as they remain the same as that of March.
