Prevalence and Incidence of Dengue fever


advertisement

About prevalence and incidence statistics: The term 'prevalence' of Dengue fever usually refers to the estimated population of people who are managing Dengue fever at any given time. The term 'incidence' of Dengue fever refers to the annual diagnosis rate, or the number of new cases of Dengue fever diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Incidence (annual) of Dengue fever: about 100 to 200 cases annually in USA (NIAID)
Incidence Rate: approx 1 in 2,720,000 or 0.00% or 100 people in USA [about data]
Worldwide incidence of Dengue fever:50 million worldwide cases
Prevalance of Dengue fever: 100 to 200 cases reported annually to the U.S. Centers for Disease Control and Prevention (CDC), mostly in people who have recently traveled abroad.1 ... In 1995, 250,000 cases of DF and 7,000 cases of DHF reported in Americas 2
Worldwide prevalence of Dengue fever:Each year, tens of millions of cases of dengue fever occur and, depending on the year, up to hundreds of thousands of cases of DHF.3

Prevelance of Dengue fever discussion: The World Health Organization estimates 50 million cases of dengue infection occur each year. This includes 100 to 200 cases reported annually to the U.S. Centers for Disease Control and Prevention (CDC), mostly in people who have recently traveled abroad. From 1977 to 1994, U.S. health care workers reported to CDC 2,248 cases of dengue that had been imported into this country. Many more cases probably go unreported because some doctors do not recognize the disease. 1

In 1997, dengue is the most important mosquito-borne viral disease affecting humans; its global distribution is comparable to that of malaria, and an estimated 2.5 billion people live in areas at risk for epidemic transmission (Figure 3). Each year, tens of millions of cases of dengue fever occur and, depending on the year, up to hundreds of thousands of cases of DHF. The case-fatality rate of DHF in most countries is about 5%; most fatal cases are among children and young adults. 3
