Dengue Fever Transmission Source Has High Risk of Outbreak

Dengue fever is a mosquito-borne viral infection that can cause a range of symptoms, from mild fever to severe hemorrhagic fever. The virus is transmitted to humans through the bite of an infected mosquito, and there is no specific treatment for dengue fever. The best way to prevent dengue fever is to avoid mosquito bites.

Transmission of Dengue Fever

Dengue fever is transmitted through the bite of an infected Aedes mosquito. These mosquitoes are found in tropical and subtropical regions around the world, and they typically bite during the day. The virus is present in the saliva of infected mosquitoes, and when they bite a human, the virus is transmitted through the saliva.

Symptoms of Dengue Fever

The symptoms of dengue fever typically appear 4-10 days after being bitten by an infected mosquito. The most common symptoms of dengue fever include:

Fever

Headache

Muscle and joint pain

Nausea and vomiting

Rash

Fatigue

In severe cases, dengue fever can lead to hemorrhagic fever, which can be fatal. Hemorrhagic fever is characterized by bleeding from the nose, gums, or gastrointestinal tract.

Treatment of Dengue Fever

There is no specific treatment for dengue fever. Treatment is supportive and includes:

Rest

Fluids

Pain relievers

Anti-nausea medications

In severe cases, hospitalization may be necessary.

Prevention of Dengue Fever

The best way to prevent dengue fever is to avoid mosquito bites. To avoid mosquito bites, you should:

Wear long sleeves and pants when you are in areas where mosquitoes are present.

Use insect repellent containing DEET, picaridin, or IR3535.

Cover your windows and doors with screens.

Empty standing water from around your home, as this is where mosquitoes breed.

Outbreak Risk

Dengue fever is a major public health concern in tropical and subtropical regions around the world. The World Health Organization (WHO) estimates that there are approximately 390 million cases of dengue fever each year, and that approximately 20,000 people die from the disease.

The risk of a dengue fever outbreak is highest in areas where the Aedes mosquito is present and where there is a high population density. Outbreaks are also more likely to occur during the rainy season, when mosquitoes are more active.

Current Outbreak

There is currently a dengue fever outbreak in the Philippines. The outbreak began in February 2019, and as of April 2019, there have been over 100,000 cases of dengue fever reported. The outbreak has caused over 600 deaths.

The Philippine government has declared a national emergency in response to the outbreak. The government is working to control the outbreak by spraying insecticides, distributing mosquito nets, and educating the public about dengue fever prevention.

Conclusion

Dengue fever is a serious public health concern in tropical and subtropical regions around the world. The best way to prevent dengue fever is to avoid mosquito bites. If you are traveling to an area where there is a risk of dengue fever, be sure to take precautions to avoid mosquito bites.
