$\huge{\underbrace{\overbrace{\mathbb{\pink{ANSWER}}}}}$

what is dengue ?

A mosquito-borne viral disease occurring in tropical and subtropical areas.

Those who become infected with the virus a second time are at a significantly greater risk of developing severe disease.

Symptoms include high fever, headache, rash and muscle and joint pain. In severe cases there is serious bleeding and shock, which can be life threatening.

Treatment includes fluids and pain relievers. Severe cases require hospital care.

health talk of dengue

An estimated 400 million dengue infections occur worldwide each year, with about 96 million resulting in illness. Most cases occur in tropical areas of the world, with the greatest risk occurring in:

• The Indian subcontinent

• Southeast Asia

• Southern China

• Taiwan

• The Pacific Islands

• The Caribbean (except Cuba and the Cayman Islands)

• Mexico

• Africa

Central and South America (except Chile, Paraguay, and Argentina)

Most cases in the United States occur in people who contracted the infection while traveling abroad. But the risk is increasing for people living along the Texas-Mexico border and in other parts of the southern United States. In 2014, an outbreak of dengue fever was identified in Hawaii with other outbreaks in 2013 in Brownsville, Texas and Key West, Fla.

Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in their blood. It can’t be spread directly from one person to another person.

Symptoms of Dengue Fever

Symptoms, which usually begin four to six days after infection and last for up to 10 days, may include

• Sudden, high fever

• Severe headaches

• Pain behind the eyes

• Severe joint and muscle pain

• Fatigue

• Nausea

• Vomiting

Skin rash, which appears two to five days after the onset of fever

Mild bleeding (such a nose bleed, bleeding gums, or easy bruising)

Sometimes, symptoms are mild and can be mistaken for those of the flu or another viral infection. Younger children and people who have never had the infection before tend to have milder cases than older children and adults. However, serious problems can develop. These include dengue hemorrhagic fever, a rare complication characterized by high fever, damage to lymph and blood vessels, bleeding from the nose and gums, enlargement of the liver, and failure of the circulatory system. The symptoms may progress to massive bleeding, shock, and death. This is called dengue shock syndrome (DSS).

People with weakened immune systems as well as those with a second or subsequent dengue infection are believed to be at greater risk for developing dengue hemorrhagic fever.

Answer 2

Answer:

Dengue (pronounced DENgee) fever is a painful, debilitating mosquito-borne disease caused by any one of four closely related dengue viruses. These viruses are related to the viruses that cause West Nile infection and yellow fever.
