Dengue Symptoms Philippines
Four kinds of viruses that belong to the Flaviviridae family cause dengue, a form of viral infection. These viruses then get transmitted through bites of infected Aedes albopictus and Aedes aegypti female mosquitoes feeding both outdoors and indoors during the daytime. These mosquitoes grow well in places with stagnant water such as water tanks, old tires, containers, and puddles.
Lack of regular trash collection and reliable sanitation can also contribute to the quick increase of mosquito population.
Risk of Dengue
Dengue risks are present in subtropical and tropical areas of Asia, Africa, South America, Oceania, and Central America. All travelers are at high risks when there are outbreaks. Humanitarian workers and long-term travelers who visit areas with endemic dengue cases are at a much higher risk. Dengue can occur in both suburban and urban settings and higher rates of transmission happen during the rainy season.
Symptoms of Dengue
There are instances when dengue infection can be asymptomatic. This means that the patient doesn’t exhibit any symptoms at all. Meanwhile, those who have symptoms can get ill within 4 to 7 days after being bitten by the infected mosquito.
Dengue infection is best characterized by symptoms that resemble those of flu. These include a sudden high fever that comes in separate waves, pain in the bones, joints, and muscles, severe headache, a rash on the skin with red spots, and pain at the back of the eyes. Treatment will include supportive care of these symptoms. No antiviral treatment is available yet that can fight off dengue.
The illness may also progress to DHF or Dengue Hemorrhagic Fever. The symptoms can include vomiting, severe pain in the abdomen, convulsions, diarrhea, uncontrolled bleeding, and bruising. High fever can also last from 2 to 7 days. The complications may result in shock and failure of the circulatory system and can even be fatal or what is called the Dengue Shock Syndrome.
In the event that you get infected with a similar serotype of the Dengue virus, you will become immune to infections in the future. But, if you get infected afterward with another serotype, your immunity will wane over time and this will increase the risks of developing the Dengue Hemorrhagic Fever.
Dengue infection is also related to the West Nile Virus, Japanese Encephalitis, Yellow Fever, and Zika Virus. It can also get misdiagnosed for Yellow Fever, Zika Virus, or Chikungunya.
Tips to Prevent Dengue
It is important for travelers to practice meticulous measures in order to prevent getting bitten by mosquitoes during the daytime. Here are a few helpful tips:
- Wear clothes with neutral colors such as light grey or beige. If possible, it is best to wear breathable and long-sleeved garments.
- Use repellents that contain 20% Picaridin or 20% to 30% DEET on your exposed skin. You can re-apply as recommended by the manufacturer.
- If available, you can spray or pre-soak outer gear and layer clothing with permethrin.
- Apply sunscreen then follow this by your chosen repellent possibly after 20 minutes.
- Get rid of all water containers in your premises and make sure that window and door screens are all working properly.
