Dengue as a cause of acute undifferentiated fever in Vietnam

Abstract

Background: Dengue is a common cause of fever in the tropics but its contribution to the total burden of febrile illnesses that is presented to primary health facilities in endemic regions such as Vietnam, is largely unknown. We aimed to report the frequency of dengue as a cause of fever in Binh Thuan Province, to describe the characteristics of dengue patients, and analyze the diagnostic accuracy of the health care workers and the determinants of the diagnostic process.

Biological, Physical, Social, and Environmental Factors Associated with Dengue Hemorrhagic Fever in Nganjuk, East Java

“…The result of this study supported a study conducted in Vietnam in 2008 by Phuong et al (2008) which stated that from the five variables, the presence of numerous plants near the house was the factor that affect the incidence of DHF (RR 2,22;95% CI 1,17). In addition, a study by Winarsih (2011) in Semarang stated that there was a relationship between the existence of plants and the incidence of DHF.…”

A study of Etiological Pattern in an Epidemic of Acute Febrile Illness During Monsoon in a Tertiary Health Care Institute of Uttarakhand, India

“…Male female ratio was 1:2 [ [8][9][10][11][12]. One third of all cases of acute undifferentiated non-malarial fever in Vietnam are caused by dengue [13]. In a similar study from Karnataka, 100 patients of acute febrile illness were diagnosed with: scrub typhus (33%); dengue (25%); enteric fever (14%); malaria (8.0%) [14].…”

Dengue in Southeast Asia: epidemiological characteristics and strategic challenges in disease prevention

“…This group of patients represents a large proportion of those with symptomatic dengue infection, depending on the age of the patient and the strain of infecting virus 28 . Since it is difficult to differentiate mild dengue from other causes of undifferentiated fever clinically, it would be impossible to carry out passive surveillance on such dengue cases.…”
