Dengue fever is a painful, weakening mosquito-borne infection brought about by any of four firmly related dengue viruses. These viruses are identified with the infections that cause West Nile contamination and yellow fever.

Mild dengue fever causes a high fever and influenza-like side effects. The extreme type of dengue, likewise called dengue hemorrhagic fever, can cause serious bleeding, an abrupt drop in blood pressure (shock) and death

A huge number of cases of dengue disease happen worldwide every year. Dengue fever is generally normal in

• The Indian subcontinent
• Southeast Asia
• Southern China
• Taiwan
• The Pacific Islands
• The Caribbean (with except and the Cayman Islands)
• Mexico
• Africa
• Focal and South America

Dengue fever is sent by the bite of an Aedes mosquito contaminated with a dengue virus. The mosquito becomes tainted when it bites a person with the dengue infection in their blood. It can’t be spread straight forward with one person then onto the next person.

Scientists are dealing with dengue vaccines. Until further now, in regions where dengue fever is normal, the most ideal ways of preventing disease are to try not to be bitten by mosquitoes and to find ways to reduce the mosquito population.

Many people experience no signs or side effects of dengue fever.

when side effects do happen, they might be confused with other diseases — like seasonal influenza — and for the most part start 4 to 10 days after you are bitten by a tainted mosquito.

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

• Unexpected, high fever
• Extreme migraines
• Agony behind the eyes
• Extreme joint and muscle torment
• Weariness
• Sickness
• Heaving
• Skin rash, which seems two to five days after the beginning of fever
• Mild bleeding (such a nose das rain, draining gums, or simple swelling)

Now and again, symptoms are mild and can be mistaken with those of seasonal influenza or another viral infection. Younger children and people who have never had the contamination before will generally have milder cases than more seasoned kids and adults. In any case, significant issues can create. These include dengue hemorrhagic fever, an uncommon inconvenience described by high fever, harm to lymph and veins, bleeding from the nose and gums, growth of the liver, and sometimes failures of the circulatory system. The symptoms might be indications of massive bleeding, shock, and death. This is called dengue shock disorder (DSS).

A person with debilitated immune systems just as those with a second or subsequent dengue virus are at greater risk for developing dengue hemorrhagic fever.

many people recover within a week in some cases, symptoms worsen and can become life-threatening. This is called serious dengue, dengue hemorrhagic fever or dengue shock disorder.

Serious dengue happens when your blood vessels become harmed and leaky. What’s more, the quantity of clot-forming cells (platelets) in your circulatory system drops. This can prompt shock, internal bleeding, organ failure and even death.

Diagnosing Dengue Fever

A doctor can determine dengue fever to have a blood test to check for the infection or antibodies to it. If you become sick after travelling to a tropical region, let your doctor know. This will allow your doctor to assess the possibility that your symptoms were brought about by a dengue disease.

Risk factors

You have more danger of creating dengue  or a more extreme type of illness if:

You live or travel in tropical regions. Being in tropical and subtropical regions increases the chances of infection that causes dengue .

You have had dengue before. Previous infection with a dengue fever infection increases your danger of serious symptoms if you get dengue fever once more.

Prevention

Dengue fever Vaccines

In spaces of the world where dengue fever is normal, one dengue fever vaccine (Dengvaxia) is approved for people ages 9 to 45 who have as of now had dengue fever once. The antibody is given in three dosages throughout the year.

The antibody is supported uniquely for people who have a history of dengue fever or who have had a blood test that shows the previous infection with one of the dengue infections — called seropositivity. In people who have not had dengue fever previously (seronegative), getting the antibody seems to expand the risk of extreme dengue fever and hospitalization because of dengue fever in future.

To protect yourself:

Use mosquito repellent, even inside.

when you are outside, wear long-sleeved shirts and long jeans tucked into socks.

When inside, use an air conditioner if possible.

Ensure window and doors screens are secure and free from holes. If sleeping regions are not screened or cooled, use mosquito nets.

If you have symptoms of dengue, address your doctor.

To prevent the mosquito population, rid of places where mosquitoes can raise. These include old tires, jars, or window boxes that gather rain. Routinely change the water in open-air water basins and pets’ water dishes.

If somebody in your home gets dengue fever, be particularly watchful with regards to endeavours to shield yourself and other relatives from mosquitoes. Mosquitoes that bite the tainted relative could spread the disease to others in your home.
