This study reports observations on dengue cases from a virus diagnostic laboratory of a north Indian tertiary care hospital catering to areas in and around Lucknow, Uttar Pradesh. Zika vs. Dengue: symptoms and diagnosis. Dengue virus (DENV), the etiological agent of dengue fever (DF) is a single, positive-stranded RNA virus of the genus Flavivirus under family Flaviviridae. Dengue fever (also known as break-bone fever) is a severe flu-like illness caused by a viral infection spread by Aedes mosquitoes. Dengue is endemic throughout the tropics and subtropics and is a leading cause of febrile illness among travelers returning from Latin America, the Caribbean, and Southeast Asia. [Medline] .

As the global shipping industry expanded in the 18th and 19th centuries, port cities grew and became more urbanized, creating ideal conditions for the pr … While most infections result in little or no symptoms, occasional inflammation of the brain occurs. Significant outbreaks of dengue fever tend to occur every five or six years. The viruses are transmitted to humans by the bite of an infected mosquito. Annually, 100 million cases of dengue fever and half a million cases of DHF occur worldwide. G. Period of Communicability All body fluids and excreta are infected from Ebola symptom onset. PPT. The majority of dengue viral infections are self-limiting, but complications may cause high morbidity and mortality. Tropical Medicine : Dengue Fever PPT Presentation Summary : Dengue Fever. Dengue can become severe within a few hours. The five year average cases of dengue is 185,008; five year average deaths is 732; and five year average Case Fatality Rate is 0.39 (2012-2016 data). References. They are RNA viruses that belong to the Flavivirus genus/Flaviviridae family, which also includes yellow fever virus, West Nile virus, Japanese encephalitis virus, Zika virus, and the St Louis encephalitis virus. Dengue fever and dengue hemorrhagic fever (DHF) are acute febrile diseases transmitted by mosquitoes, which occur in the tropics.

These guidelines were developed based on the best available evidence at the Dengue has been known to be endemic in the Central Highlands region, Vietnam for over 30 years. • Severe dengue: dengue with any or more of the following scenarios: o Severe plasma leakage evidenced by hypovolemic shock and/or extravascular fluid accumulation with respiratory distress possibly with a abnormally high hematocrit value. This document includes the new concepts on fluid management of Dengue Haemorrhagic Fever patients and replaces the existing national guidelines on clinical management of Dengue Fever / Dengue Haemorrhagic Fever published by Epidemiology Unit Ministry of Health in 2005. in: Gubler D.J. Dengue fever is an endemic disease in some districts of Tamil Nadu and State Public Health Department is tracking the dengue scenario carefully. • There are four distinct serotypes, DEN-1, 2, 3 and 4. There are four dengue virus (DENV) types (DENV-1, DENV-2, DENV-3, and DENV-4), all of which are capable of inducing severe disease (dengue hemorrhagic fever [DHF]/dengue shock syndrome [DSS]).

Dengue is a viral disease transmitted by mosquitoes (especially Aedes aegypti) and is widely distributed throughout the tropics and subtropics.Dengue classically presents with high fever, headache, body aches, exanthem, and generalized lymphadenopathy.Symptoms usually subside within one week. The Epidemiology Unit was established in 1959 with assistance from World Health Organization (WHO) to strengthen surveillance of communicable diseases. In this brief article, I … This acute febrile illness can be a deadly infection in cases of severe manifestation, causing dengue hemorrhagic shock. • Dengue-like illness: illness defined by fever as reported by the patient or healthcare provider. Ninety percent of DHF subjects are children less than 15 years of age. I. Dengue fever is a mosquito-borne viral disease caused by 1 of 4 closely related but antigenically distinct serotypes of dengue virus, serotypes DENV-1 through DEN-4. Epidemiology. Dengue is a mosquito-borne viral infection. Dengue occurs in >100 countries worldwide ( Maps 4-01 through 4-03 ), including Puerto Rico, the US Virgin Islands, and US-affiliated Pacific Islands. This occurs about 5 to 15 days after infection. • Dengue haemorrhagic fever is a leading cause of serious illness and death among children in some Asian countries. Background . Records of dengue-like illness date back more than 200 years; the viral etiology of dengue virus was established in the 1940s [ 1,2 ]. Approximately half of the world's population is at risk, especially people residing in tropical and subtropical climates such as in Bangladesh. Virus, Vector and Epidemiology. INTRODUCTION. Summary. The clinical manifestations range from asymptomatic infection to undifferentiated fever, dengue fever and dengue hemorrhagic fever (DHF). Dengue hemorrhagic fever (severe): leaking blood vessels, destruction of platelets result in blood clotting abnormalities and cause patient to go into potentially fatal shock because of fluid loss. 3. They may range from subclinical infection to dengue fever, dengue hemorrhagic fever (DHF), and eventually dengue shock syndrome (DSS). The survey findings will be useful in making informed decisions about introduction of upcoming dengue vaccines in India. Four dengue viruses (DENVs) are transmitted by urban cycle mosquitoes causing diseases whose nature and severity are influenced by interacting factors such as virus, age, immune status of the host, and human genetic variability. The incidence and geographical distribution of dengue have greatly increased in recent years. This acute febrile illness can be a deadly infection in cases of severe manifestation, causing dengue hemorrhagic shock. Health effects from dengue include fever, headache, nausea, vomiting, rash, muscle and joint pain, and minor bleeding. Complications can lead to circulatory system failure and shock, and can be fatal (also known as Dengue Shock Syndrome). Dengue fever is a common mosquito-borne illness in many tropical and subtropical countries. The burden is increasing and considered driven by population densities, human mobility, vector proliferation, and climate variability.
