Dengue & Dengue Haemorrhagic Fever in Bangladesh

Dengue (pronounced as 'Dhen Gey') is a mosquito borne febrile viral illness. Since its first recognition during the last quarter of eighteenth century, periodic outbreak has been reported from both developed and developing countries with Asia always remaining the area of highest endemicity Until the middle of 20th century dengue was regarded as self-limited, non-fatal febrile illness with occasional hemorrhagic manifestations that only rarely resulted in severe or fatal outcome. Epidemic dengue with severe hemorrhagic manifestations was first reported in the Philippines in 1956 Since then epidemics which came to be known as dengue hemorrhagic fever (DHF) have occurred periodically in other Southeast Asian countries and term dengue shock syndrome(DSS) was subsequently coined to describe cases of dengue associated with increased vascular permeability leading to intravascular hypovolemia and shock.
