Diseases caused by arboviruses ‐ dengue haemorrhagic fever and Japanese B encephalitis

Abstract
Dengue haemorrhagic fever is a recent and more serious variant of dengue infection, causing significant mortality in children under 14 years of age in South-East Asia and the Western Pacific regions. Successful treatment depends on early recognition of the disease and careful monitoring of the development of shock. Japanese B encephalitis has a case fatality rate of 10%-30% in these regions, but may be controlled by vaccination.
