Transmission of dengue hemorrhagic fever in an age structured population

A realistic age structured transmission model for dengue hemorrhagic fever in Thailand.

The influence of age structure in the susceptible class of the Susceptible-Infected Recovered (SIR) model used to describe the transmission of dengue hemorrhagic fever (DHF) was studied. This was done by first dividing all of the population classes into cohorts and then writing a set of coupled SIR equations for each cohort. The consequences of assuming different behavior of the transmission ra...

Dengue and dengue hemorrhagic fever.

Continued geographic expansion of dengue viruses and their mosquito vectors has seen the magnitude and frequency of epidemic dengue/dengue hemorrhagic fever (DF/DHF) increase dramatically. More than 200,000,000 infections and over 2 million cases of DHF occur annually, and dengue is one of the most important emerging tropical diseases in the world. Its dramatically increased incidence and geogr...

Dengue and Dengue Hemorrhagic Fever

Dengue and dengue hemorrhagic fever.

Dengue fever, a very old disease, has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors, increased epidemic activity, the development of hyperendemicity (the cocirculation of multiple serotypes), and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tro...

Recent Shift in Age Pattern of Dengue Hemorrhagic Fever, Brazil

To the Editor: Brazil is responsible for >60% of reported cases of dengue fever (DF) in the American region (a designation of the Pan American Health Organization, which includes all of North, Central, and South America) (1). The epidemiologic characteristics of dengue diseases in Brazil differ from those described in Southeast Asia. In Brazil, the incidence of DF and dengue hemorrhagic fever (...
