Dengue is an acute viral illness caused by RNA virus of the family Flaviviridae and spread by Aedes mosquitoes. Presenting features may range from asymptomatic fever to dreaded complications such as hemorrhagic fever and shock. A cute-onset high fever, muscle and joint pain, myalgia, cutaneous rash, hemorrhagic episodes, and circulatory shock ...

Immunopathogenesis. Dengue is transmitted from person to person via the bite of an infected mosquito. Of these, the primary vector is Aedes aegypti, which is a highly domestic mosquito, a day biter, breeding in water containers in peri-domestic areas.Its eggs could survive without desiccation in dried condition for months and, with the first opportunity of contact with water, the life cycle ...

Dengue is an important public health problem with a wide clinical spectrum. The World Health Organization classifies dengue into probable dengue, dengue with warning signs, and severe dengue. Severe dengue, characterized by plasma leakage, severe bleeding, or organ impairment, entails significant morbidity and mortality if not treated timely.

Abstract. Dengue is caused by the dengue virus (DENVs) infection and clinical manifestations include dengue fever (DF), dengue hemorrhagic fever (DHF), or dengue shock syndrome (DSS). Due to a lack of antiviral drugs and effective vaccines, several therapeutic and control strategies have been proposed. A systemic literature review was conducted ...

Dengue, or dengue fever, is a disease caused by infection with the dengue virus (DENV), a member of the Flavivirus genus (Flaviviridae) that also includes yellow fever and Japanese encephalitis. Milder cases can range from asymptomatic to clinical manifestations that include high fever, severe headaches, retro-orbital pain, joint and muscle pains, vomiting and rash. DENV is classified into ...

Dengue, caused by four closely related viruses, is a growing global public health concern, with outbreaks capable of overwhelming health-care systems and disrupting economies. Dengue is endemic in more than 100 countries across tropical and subtropical regions worldwide, and the expanding range of the mosquito vector, affected in part by climate change, increases risk in new areas such as ...

Background The World Health Organization (WHO) has ranked dengue as one of the top ten threats to Global health in 2019. Sri Lanka faced a massive dengue epidemic in 2017, the largest outbreak in the country during the last three decades, consisting of 186,101 reported cases, and over 320 deaths. The epidemic was controlled by intense measures taken by the health sector. However, the reported ...

It is caused by any of the 4 serotypes of dengue virus and is transmitted within humans through female Aedes mosquitoes. Dengue disease varies from mild fever to severe conditions of dengue hemorrhagic fever and shock syndrome. Globalization, increased air travel, and unplanned urbanization have led to increase in the rate of infection and ...

Dengue is the disease caused by 1 of 4 distinct, but closely related dengue viruses (DENV-1-4) that are transmitted by Aedes spp. mosquito vectors. It is the most common arboviral disease worldwide, with the greatest burden in tropical and sub-tropical regions. In the absence of effective prevention and control measures, dengue is projected to increase in both disease burden and geographic ...

Dengue fever is a dengue virus infection, emerging rapidly and posing public health threat worldwide, primarily in tropical and subtropical countries. Nearly half of the world's population is now at risk of contracting the dengue virus, including new countries with no previous history-like Ethiopia. However, little is known about the epidemiology and impact of the disease in different countries.

1. Introduction to Dengue (1) Overview.Dengue is an infectious disease caused by any of the four dengue virus serotypes: DENVs 1-4. It is a mosquito-borne disease and is primarily transmitted to humans by the female Aedes mosquito. The disease is mainly concentrated in tropical and subtropical regions, putting nearly a third of the human population, worldwide, at risk of infection [].

Among the respondents, 93.8% had heard about dengue fever (DF) and most of them (61.3%) were aware of dengue outbreak in Bangladesh (Table 2). Most (91.3%) believed that it was transmitted through mosquito bites. A small number (2.1%) opined that this disease is trans-mitted through dirty drinking water.

Dengue fever is a rapidly emerging tropical disease and an important cause of morbidity in its severe form worldwide. A wide spectrum of the pathophysiology is associated with the transition of dengue fever to severe dengue, which is driven by the host immune response and might reflect in patients' proteome profile. This study aims to analyze the plasma from different phases of dengue ...

Clinically, the manifestations of DENV infection can range from mild-acute undifferentiated febrile illness to classical dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) according to WHO 1997 dengue guideline 1 (Fig. 1).DF is an acute febrile illness that presents symptoms such as bone or joint and muscular pains, headaches, leukopenia and rash.

Author summary Dengue fever, an extensively spread mosquito-borne disease, is endemic in more than 100 countries. Information about dengue disease burden, its prevalence and incidence and geographic distribution is necessary to guide in planning appropriate control measures including the dengue vaccine that has recently been licensed in a few countries. We performed a systematic review and ...

Most people with dengue have no symptoms. Approximately one-quarter of people have mild illness that develops 4 to 7 days after being bitten by an infected mosquito. The most common symptom of dengue is fever, which may be accompanied by pain in the eyes, bones, joints, and muscles, as well as nausea, vomiting, and rash.

Dengue is a mosquito-transmitted virus and is the leading cause of arthropod-borne viral disease worldwide, posing a significant global health concern. This disease is also known by various monikers, such as breakbone or 7-day fever, and is characterized by intense muscle spasms, joint pain, and high fever, reflecting both the severity and the duration of symptoms. Although most dengue fever ...

we divided dengue progression into two groups: individuals who progressed to severe disease (defined as dengue haemorrhagic fever according to 1997 guidelines or severe dengue according to 2009 guidelines) and individuals who did not progress to severe disease (dengue fever and non-severe dengue; appendix pp 5-7). Each risk factor was ...

In this image, the autors reinterprate "The Thinker" from Auguste Rodin to transfer knowledge about dengue fever, which can range from flu-like illness to severe hemorrhagic fever. By fostering awareness and understanding of dengue fever, we strive to empower individuals and communities in the ongoing fight against dengue and other infectious threats.

Background: Dengue hemorrhagic fever (DHF) is the most prevalent and fastest-growing vector-borne disease globally, with symptoms ranging from mild to severe and, in some cases, fatal. Quang Nam province in Vietnam can serve as a model for dengue epidemiological study, as it is an endemic region for DHF with a tropical climate, which significantly constrains the health system.

1 Introduction. Flaviviruses are single-stranded, positive-sense RNA viruses that are transmitted by insect vectors, and they belong to one of the four genera within the family Flaviviridae (Gould and Solomon, 2008).Over recent decades, notable flaviviruses such as Dengue virus (DENV), West Nile virus (WNV), Zika virus (ZIKV), and yellow fever virus (YFV) have been responsible for the ...

Dengue outbreaks occur in many countries of the world, including North and South Americas, Africa, the Middle East, Asia, and the Pacific Islands. Almost half of the world's population, about 4 billion people, live in areas where dengue outbreaks could occur. Although dengue is more common in tropical regions, it's not limited to those areas.
