Epidemiological analysis of hospitalized cases of dengue fever/dengue haemorrhagic fever and extent of breeding of Aedes aegypti in major hospitals in the National Capital Territory of Delhi (NCT Delhi), 2005–2009.
AbstractDengue is a notifiable disease in the National Capital Territory of Delhi (NCT Delhi), India. All hospitals, both in the public and private sectors, are under obligation to report serologically confirmed cases of dengue to local health authorities. During the period 2005 to 2009, a total of 7402 serologically confirmed dengue cases were reported from the National Capital Territory of Delhi. Records of 5603 dengue cases (76%) admitted in hospitals were analysed for severity of disease. The trend of dengue has changed from cyclic to annual occurrence. DHF/DSS accounted for 518 (9.2%) of the admitted hospital cases in all age groups. The proportion of males found positive for dengue infection was 68% while females constituted 32%. The transmission season in NCT Delhi is the rainy season (July to October). Container indices monitored in six major hospitals remained persistently high in all the five years (range 1.5 to 23.9) and carried high potential for spatial spread of dengue infection to other parts of the NCT, Delhi region.

World Health Organization, Regional Office for South-East Asia (1999)In the past 15 years, we have witnessed a dramatic increase in the global incidence of dengue and its severe manifestations such as dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). increasing magnitude. More than 2.5 billion people are at risk of infections in over 200 countries worldwide. There are probably tens of millions of cases of dengue each year, and at least five hundred thousand cases of DHF with a mortality of about five per cent in most countries. The vast majority of cases, nearly 95 per cent, are among children of ...
