Dengue is a viral infection caused by five types of viruses (DENV) belonging to the Flavivirdae family.
The viruses are transmitted through the bite of infected Aëdes aegypti and Aëdes albopictus female mosquitoes that feed both indoors and outdoors during the daytime (from dawn to dusk).
In 2013, scientists confirmed the existence of a fifth Dengue virus serotype which could pose a further challenge to developing a vaccine against the infection in humans. Dengue vaccination needs to exist soon!
Dengue Awareness Tips For Travelers
If you’re planning a trip to Nepal or already exploring our beautiful country, you might be curious about dengue.
We understand your concerns and are here to provide you with all the necessary information about dengue in Nepal.
So far, 1,544 people have been diagnosed with dengue in 73 districts with kathmandu and Jhapa being the highest.
185 individuals in Kathmandu and 123 individuals in Jhapa had confirmed cases of dengue this year.
Risks of Dengue
The viruses are present in tropical and subtropical areas of Central America, South America, Africa, Asia, and Oceania.
Long-term travelers and aid or missionary workers going to areas where Dengue is endemic are at higher risk. Dengue occurs in urban and suburban settings with higher transmission rates happening during the rainy season.
Let’s Take A Look On Some Symptoms of Dengue
In some cases, Dengue infection is asymptomatic (persons do not exhibit symptoms). Those with symptoms get ill between 4 to 7 days after the bite.
The infection is characterized by:
- A sudden high fever coming in separate waves
- Pain behind the eyes
- Muscle, joint, and bone pain
- Severe headache
- Rashes on the skin characterized by bright red spots
The illness may progress to Dengue Hemorrhagic Fever (DHF). Symptoms include
- Severe abdominal pain
- Vomiting
- Diarrhea
- Convulsion
- Bruising
- Uncontrollable bleeding
High fever can last from 2 to 7 days. Complications can lead to circulatory system failure and shock and can be fatal.
Exposure to one type of Dengue virus does not provide immunity to the other three types. Contracting Dengue more than once increases the risk of developing Dengue Hemorrhagic Fever.
Preventive Measures Of Dengue
Travelers should take these measures to prevent mosquito bites during the daytime:
- Apply DEET-containing repellent to exposed skin.
- Use permethrin spray on clothing and gear.
- Wear long sleeves and pants.
- Remove water containers around dwellings.
- Ensure door and window screens are working properly.
There is currently no preventive medication or vaccine against Dengue. Dengue fever cases have been reported in Nepal (Kathmandu).
