Clinical Features of Dengue
About 1 in 4 dengue virus infections are symptomatic. Approximately 1 in 20 patients with dengue progress to develop severe, life-threatening disease called severe dengue. ... people can be infected with DENV multiple times in their life. Clinical presentation. Dengue begins abruptly after a typical incubation period of 5-7 days, and the ...

Vital Signs: BP: 110/80 HR: 104 RR: 18 T: 100.4°F (38 °C) Choose the TRUE statement. Patients with dengue do not present with respiratory symptoms, therefore this patient does not have dengue. It is more likely that this patient has malaria than dengue. This patient is in the febrile phase, given her temperature.

Dengue virus infection: Clinical manifestations and diagnosis
Dengue fever — DF (also known as "break-bone fever") is an acute febrile illness defined by the presence of fever and two or more of the following but not meeting the case definition of DHF [ 4] (see 'Dengue hemorrhagic fever' below): Headache. Retro-orbital or ocular pain. Myalgia and/or bone pain. Arthralgia.
Dengue and severe dengue
Dengue and severe dengue. Dengue is a mosquito-borne viral infection that is common in warm, tropical climates. Infection is caused by any one of four closely related dengue viruses (called serotypes) and these can lead to a wide spectrum of symptoms, including some which are extremely mild (unnoticeable) to those that may require medical ...
Dengue Fever
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.
Dengue fever
You have had dengue fever in the past. Previous infection with a dengue fever virus increases your risk of severe symptoms if you get dengue fever again. Complications. Severe dengue fever can cause internal bleeding and organ damage. Blood pressure can drop to dangerous levels, causing shock. In some cases, severe dengue fever can lead to death.
PDF Fact sheet Dengue and severe dengue
nd adults, but seldom causes death.Dengue should be suspected when a high fever (40°C/ 104°F) is accompanied by two of the following symptoms: severe headache, pain behind the eyes, muscle and joint pains, nause. , vomiting, swollen glands or rash. Symptoms usually last for 2-7 days, after an incubation period of 4-10 days after.
Dengue
Dengue, an acute febrile illness, is caused by infection with any of 4 related single-stranded RNA viruses of the genus Flavivirus, dengue virus 1, 2, 3, or 4 (DENV1-4). Infection with one DENV confers long-term immunity to that virus but conveys only short-lived protection against the other dengue viruses. The risk for severe dengue is ...
Dengue
Dengue is a mosquito-borne viral disease caused by the dengue virus, with the potential to cause a serious public health impact. Dengue infections are the most common vector-borne viral infections worldwide, particularly impacting tropical and subtropical countries. DENV has the potential to cause epidemics resulting in high morbidity and ...
Dengue Viruses
The dengue virus is a tiny structure that can only replicate inside a host organism. The four closely related dengue viruses — DEN-1, DEN-2, DEN-3, and DEN-4 — are found in the same regions of ...
Dengue
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 ...
Dengue virus: epidemiology, biology, and disease aetiology
Dengue is a vector-borne viral disease caused by the flavivirus dengue virus (DENV). Approximately 400 million cases and 22 000 deaths occur due to dengue worldwide each year. It has been reported in more than 100 countries in tropical and subtropical regions. A positive-stranded enveloped RNA virus (DENV) is principally transmitted by Aedes mosquitoes. It has four antigenically distinct ...

Several important features of dengue disease • Dengue virus infection causes diverse disease spectrum from mild DF to severe DHF/DSS. • Dengue disease can occur in infant, children, and adult. • Severe DHF/DSS is more prevalent in secondary infection with different serotype of dengue virus. • Antibody-dependent enhancement is ...
DENGUE FEVER.pptx
Dengue fever (DF) has symptoms similar to other viral illnesses. High grade fever with severe body aches and headache are most common symptoms. Virus attacks the white blood cells. It also attacks platelets and lining cells of blood vessels. Mild bleeding tendency can occur.

Increased Oropouche Virus Activity and Associated Risk to Travelers
The incubation period is typically 3-10 days. Initial clinical presentation is similar to diseases caused by dengue, Zika, and chikungunya viruses, with acute onset of fever, chills, headache, myalgia, and arthralgia. Other symptoms can include retroorbital (eye) pain, photophobia (light sensitivity), nausea, vomiting, diarrhea, fatigue ...
Oropouche virus disease
Given its clinical presentation and considering that this is the ongoing season for dengue in Central America and the Caribbean and for other vector-borne diseases in the Region of the Americas, laboratory diagnosis is essential to confirm cases, characterize the outbreak, and monitor disease trends.
