Clinical spectrum during dengue haemorrhagic fever epidemics in Tirupur (India)

摘要

Dengue is an acute viral disease caused by any of four dengue virus serotypes (DEN 1-4). A small proportion of infected persons may develop the severe form of disease, dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). All over 99% of the cases of viral haemorrhagic fever reported worldwide are related to DHF1. Dengue fever (DF) has great variability of clinical features, which depends on many factors such as person, place and time2"3. It may be confused clinically with other infections, viz. influenza, measles, typhoid, leptospirosis and any non-specific viral syndromes.
