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...

Between July 1975 and April 1980, 71 patients were admitted to the Second Attached Hospital of Hubei Provincial Medical College in Wuchang with the diagnosis of epidemic hemorrhagic fever (EHF). The clinical course among these patients was similar to that described for patients with Korean hemorrhagic fever, and hemorrhagic fever with renal syndrome of the U.S.S.R. The overall mortality was 11....

OBJECTIVE Dengue hemorrhagic fever is a public health problem in Mexico since 1994. With four serotypes circulating the risk of epidemic dengue hemorrhagic fever is increasing. MATERIAL AND METHODS We describe the clinical features of confirmed cases in the social security health system (IMSS) from 1995 to 2003. Clinical picture and epidemiological features were compared and a multivariate mo...

conclusions the viral load in patients who suffer from cchf has a direct significant correlation with disease severity. viral load above 8.6 × 105 copies/ml on the first day of admission is a predictor of severe cchf. background crimean-congo hemorrhagic fever (cchf) is an endemic disease in south eastern of iran, especially in sistan and baluchestan province. cchf is a potentially fatal diseas...

We are living with a lot of diseases related to fevers different names like Chikungunya fever, West Nile rheumatic Relapsing Rat-bite fever (sodoku), Haver hill Dengue Typhoid Scarlet Viral hemorrhagic etc.

Crimean-Congo hemorrhagic fever and dengue hemorrhagic fever are endemic in Pakistan. However, the overlap of geographic distribution and early clinical features between the two conditions make a reliable diagnosis difficult in the initial stage of illness. A 16-year-old boy presented with a history of hematemesis and high-grade fever. A preliminary diagnosis of dengue hemorrhagic fever was mad...

Unlike present times, when the major health concerns for Grenada are chronic diseases, the island’s main health problems in the past were infectious diseases. The aim of this review is to examine whether a hemorrhagic fever epidemic precisely occurred in Grenada in the 1700s, and to identify the mostly likely etiologic agents associated with the outbreak. The methods used to collect information...

This paper reviews the epidemiology and distinguishing features of three viral hemorrhagic fevers (dengue hemorrhagic fever, yellow fever and arenaviral hemorrhagic fever) that have emerged as important public health problems in South America. Although the etiology, natural history and control of the three diseases are different, their clinical manifestations and histopathology findings are sim...
