Case Study

As a Park Ranger Assistant, 16-year old Alliyah-Mariette works in the forests and lakes in the Philippines. The area in which she works at is infested with mosquitoes and trees housing ticks. What Alliyah-Mariette doesn’t know is that this particular forest is a hot spot for Dengue, and she not knowing this resulted in a life changing experience. Her parents are on yet another business trip, this time, they are half way around the world and there is no way to contact them.

Alliyah-Mariette was used to the mosquito bites, so she decided to wear her cargo shorts and her Park Ranger Assistant t-shirt, but this time, it would be different. 3 days after she was bit by the infected mosquito Alliyah-Mariette came down with a fever and headache. She thought it was just a cold, but then later, she had muscle and joint pains and a rash that looked like measles, going from her shoulder down to her hip. That is when she decided to seek medical health. While in the hospital they ran a few tests and it turned out that she had DENV1. Alliyah-Mariette didn’t know what to do, she didn’t know how this could’ve happened, and then the doctors explained it was caused by infected mosquitoes.

The doctors gave her some aspirin and corticosteroids and sent her on her way. The doctors said that there was no cure and had a fifty percent chance of living. They said that the next time she is goes to work, to make sure that she wears clothes that cover her whole body and wear some type of bug protector. Alliyah-Mariette decided that she would wait to see how the infection turns out.

After a few weeks, the symptoms disappeared and she decided to go check if the Dengue infection left her system. The tests came back and there was no Dengue in her system. The doctors told her the same thing as before, that when she went back to work, she had to wear clothes that covered her whole body and to wear a bug deflector, like OFF!, because since she was infected with one, that doesn’t mean she has immunity to any other of the strains. There were no long lasting side effects, just soreness in her back and a small rash on her upper arm.

What are the CDC and WHO doing to prevent the spread of Denuge?

The WHO and CDC are two different organizations, but they are both working on the same thing, preventing Dengue from spreading. It doesn't stop there though, there is another organization, The Integrated Vector Control is also working on ways to prevent Dengue from spreading, but they are working on preventing the spread of Dengue vectors.The WHO is working on an effective and safe vaccination. The CDC has a DF and DHF surveillance system to watch where Dengue has shown up and who got it. The Integrated Vector Control is working on eliminating mosquitoes habits, emptying containers of water, adding insecticides and reducing open collections of water.

Where Will Dengue Occur Next?

Dengue occurs every year in the tropics and subtropics due to the amount of rainfall and humidity. Those are the perfect conditions for the population of mosquitoes to spread. There is no question about it, the tropics have the perfect conditions for a population to grow and a growing population means a growing number of cases of Dengue. 

Symptoms & Treatment

Dengue can either be asymptomatic or have mild symptoms it all depends. Those symptoms include; fever, headache, muscle and joint pains and a characteristic rash. Dengue Fever can develop Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome. Symptoms usually start 4-7 days after the mosquito bite and last 3-10 days. There is no initial treatment, though doctors recommend acetaminophen for the symptomatic fever and aspirin and corticosteriods should be advised for mild side effects. On top of there being no initial treatment, there is no cure, so you have a 50% chance of living and a 50% chance of dying. 

Description, History, and Causes:

Dengue Fever is a very common disease that first appeared around the 1950s, in the Philippines. The main cause of Dengue is from a mosquito bite of the Aedes mosquito. That isn't the only cause, there are rare possibilities of catching it like; Organ transplants, blood transfusions and from an infected mother to her fetus. There has been a dramatic increase in cases because of people not being aware of what Dengue is. There are four strains, they all cause the same symptoms and they all have the possibility of developing full spectrum of disease.

6.)Dengue can develop into Dengue Hemorrhagic Fever.
5.) Dengue's symptoms usually last 3-10 days.
4.) There is not vaccination for Dengue Fever, although if there were, the vaccination would have to fight all four strains.
3.) The fatality rate of Dengue Fever can reach 80%-90%.
2.) There is no treatment.
1.) If you contract one strain of Dengue Fever and fight it off and catch another strain, you don't have immunity to that strain.
