Dengue fever is an emerging disease occurring in tropical and subtropical areas. Prevention of infection depends on good knowledge, attitudes and practices of communities towards the disease and its control measures.1 The incidence of dengue has grown dramatically around the world in recent decades. The actual numbers of dengue cases are underreported, and many cases are misclassified. One recent estimate indicates 390 million dengue infections per year of which 96 million manifests clinically.2 The World Health Organization (WHO) estimates that 40% of the world’s population lives in areas endemic to dengue virus. The clinical spectrum of the disease varies from asymptomatic infection to severe conditions. Dengue infection is a serious public health problem both because of the spread of the disease, on a worldwide scale, and because of the increase in severe cases and deaths.3 In 2009, the WHO issued the revised dengue classification: dengue without warning signs, dengue with warning signs (abdominal pain, persistent vomiting, fluid accumulation, mucosal bleeding, lethargy, restlessness, liver enlargement, increasing hematocrit with decreasing platelets) and severe dengue (severe plasma leakage, severe bleeding or organ failure.4 The present study was conducted to assess the knowledge, attitude and practices regarding transmission and prevention of dengue fever and to determine the association between knowledge and practice.
