Symtom Of Dengue

Answer 4

G'day from South Australia, I contracted dengue fever on October 1st , 2013 on the island of Palawan and was discharged 6 days later. Compared to other patients in the ward I got off fairly lightly. I didn't get the bleeding or vomiting (DHF) and was able to eat and drink gallons of liquids while on IV. Now I went down hill whet I left hospital getting candida down the throat , massive fatigue and insomnia just to name a few. After a week I got myself back to Adelaide , South Australia and immediately started trying to juice my way to health. I mainly stuck to the green veggies like cabbage, brocoli and spinach with some carrot. Nystatin tablets got rid of my flush and I started to feel better. Staying off the sugar and junk food helped I think and within 4 weeks I started doing two 40 minute brisk walks a day. A few weeks a go I had a nasty bout of constipation for 4 days and I did some heavy straining on the toilet bowel. My BM returned to normal after taking some physilium husk and I felt this was doing me some good and it was cleaning me out internally. But as soon as my constipation ended I have had a dull ache and discomfort around the belly button Now has anyone had abdominal discomfort during PVF? Even with good BM's it does not make sense that I have abdominal discomfort........Cheers everyone Nick from Adelaide

Answer 6

Symptoms of typical uncomplicated dengue usually start with fever within 5 to 6 days after a person has been bitten by an infected mosquito.


High fever, up to 105 degrees Fahrenheit
Severe headache
Retro-orbital (behind the eye) pain
Severe joint and muscle pain
Nausea and vomiting
Rash
The rash may appear over most of the body 3 to 4 days after the fever begins. A second rash may appear later in the disease.

Interestingly, most children infected with dengue virus never develop typical symptoms.

HOW IS DENGUE FEVER DIAGNOSED?

A doctor or other health care worker can diagnose dengue fever by doing a blood test. The test can show whether the blood sample contains dengue virus or antibodies to the virus. In epidemics, dengue is often clinically diagnosed by typical signs and symptoms.

HOW IS DENGUE FEVER TREATED?

There is no specific treatment for dengue fever, and most people recover completely within 2 weeks. To help with recovery, health care experts recommend

Getting plenty of bed rest.
Drinking lots of fluids.
Taking medicine to reduce fever.
CDC advises people with dengue fever not to take aspirin. Acetaminophen or other over-the-counter pain-reducing medicines are safe for most people.

HOW CAN DENGUE FEVER BE PREVENTED?

The best way to prevent dengue fever is to take special precautions to avoid contact with mosquitoes. Several dengue vaccines are being developed, but none is likely to be licensed by the U.S. Food and Drug Administration in the next few years.

When outdoors in an area where dengue fever has been found,

Use a mosquito repellant containing DEET.
Dress in protective clothing—long-sleeved shirts, long pants, socks, and shoes.
Because Aedes mosquitoes usually bite during the day, be sure to use precautions especially during early morning hours before daybreak and in the late afternoon before dark.

Other precautions include

Keep unscreened windows and doors closed.
Keep window and door screens repaired.
Get rid of areas where mosquitoes breed, such as standing water in flower pots or discarded tires.
CAN DENGUE FEVER LEAD TO OTHER HEALTH PROBLEMS?

Most people who develop dengue fever recover completely within two weeks. Some, however, may go through several weeks of feeling tired and/or depressed.

Others develop severe bleeding problems. This complication, dengue hemorrhagic fever, is a very serious illness which can lead to shock (very low blood pressure) and is sometimes fatal, especially in children and young adults.

NIAID RESEARCH

Scientists supported by the National Institute of Allergy and Infectious Diseases (NIAID) are trying to develop a vaccine against dengue by modifying an existing vaccine for yellow fever. Researchers in NIAID laboratories in Bethesda, Maryland, are using weakened and harmless versions of dengue viruses as potential vaccine candidates against dengue and related viruses.

Other researchers supported by NIAID are investigating ways to prevent dengue viruses from reproducing inside mosquitoes.

Because dengue virus has only recently emerged as a growing global threat, scientists know little about how the virus infects cells and causes disease. New research is beginning to shed light on how the virus interacts with humans — how it damages cells and how the human immune system responds to dengue virus invasion.

Infection with dengue viruses produces a spectrum of clinical illness ranging from a nonspecific viral syndrome to severe and fatal hemorrhagic disease. Important risk factors for DHF include the strain and serotype of the infecting virus, as well as the age, immune status, and genetic predisposition of the patient. (Source: excerpt from CDC Dengue Fever Home Page: DVBID)

The principal symptoms of dengue are high fever, severe headache, backache, joint pains, nausea and vomiting, eye pain, and rash. Generally, younger children have a milder illness than older children and adults. (Source: excerpt from Dengue and Dengue Hemorrhagic Fever: Questions and Answers: DVBID)

Dengue fever may begin suddenly. Symptoms usually include high fever, severe headache, and joint and muscle pain. Nausea, vomiting, and loss of appetite are also common. A rash may appear 3 to 4 days after the fever begins and may spread from the torso to the arms, legs, and face. These early symptoms do not usually last more than 7 days and dengue does not produce long-term health effects. Because of the incubation period, travelers may not become ill until arriving home. (Source: excerpt from Spotlight on: Preventing Dengue and Dengue Hemmorhagic Fever: DVBID)

Classic dengue fever is characterized by acute onset of high fever, frontal headache, retro-orbital pain, myalgias, arthralgias, nausea, vomiting, and often a maculopapular rash. In addition, many patients may notice a change in taste sensation. Symptoms tend to be milder in children than in adults, and the illness may be clinically indistinguishable from influenza, measles, or rubella. The disease manifestations can range in intensity from inapparent illness to the symptoms described.
