Researchers Find Key Factors to Fighting the Dengue Virus
Posted by janegwalker in Dengue Fever, Uncategorized on April 12, 2012
Recent research by University of North Carolina and Vanderbilt University professors have brought the medical world one step closer to creating a vaccine to prevent Dengue Fever.
Although it is believed that humans have been fighting the dengue virus for hundreds of years, it wasn’t documented until the 1950s when it reached epidemic levels in the Philippines and Thailand. Sixty years later and it is estimated that 40% of the world’s population is at risk of dengue. Almost all the cases that were diagnosed in the United States had been contracted elsewhere while traveling. Contact between the mosquitoes that carry dengue is very uncommon in the U.S.

Mosquitoes can be dangerous when carrying certain illnesses like Dengue Fever
The dengue virus is transmitted through the bites of several types of mosquitoes under the genus Aedes which primarily live in tropical and subtropical environments. Symptoms of dengue can start 4-7 days after infection and include fever, headache, muscle and joint pain and rashes. In a small number of cases, the fever can reach a critical phase. There are four closely related strands of the virus and severe cases are more common when a person is infected with two different strands of dengue.
Until now, how the human immune system fights the dengue virus has always been somewhat of a mystery because tests had only been conducted with mice. For this study, Aravinda M. de Silva, PHD. Of UNC School of Medicine, was able to study blood cells from people that were infected with dengue while traveling abroad. De Silva and her team were able to locate what part of the virus the immune system attacked.
“’This is a huge issue for vaccine development,’ said lead study author Ruklanthi de Alwis, a graduate student in de Silva’s lab. ‘We have to figure out a way to develop dengue vaccines that induce the good response that protects against infection, at the same time avoiding the bad response that enhances disease.’” – source.
With nearly half of the world’s population at risk of contracting this vector-borne disease, it’s great news to see a better understanding of how the virus works in the human body and how our immune systems respond. Until then it is important for residents to decrease the probability of being bitten by a mosquito buy getting rid of breeding sites and proper use of mosquito control.
More information on this study will be published online in the Proceedings of the National Academy of Sciences.
2011 Brought Advances in the Fight Against Vector-Borne Illnesses

Happy New Year!
One interesting part of starting a new year is always to look over the “best of” lists: Best celebrity weddings, best technology improvements, most fascinating people, etc. Discover Magazine annually puts out the “Top 100 Stories” of the year before. This year, several of Dread Skeeter’s nemeses made the list.
#90: Chronic Lyme Patients Validated
Diagnosing Lyme disease can often be difficult as its symptoms are very similar to other ailments, and in the case of post-treatment Lyme disease syndrome, some patients have been told they either have chronic fatigue syndrome or are perfectly fine. Well, in 2011 immunologist Steven Schutzer was able to prove that there is a difference between patients with chronic fatigue and post-treatment Lyme patients, proving the syndrome does exist.
According to the Center for Disease Control, 2.5 billion people live in areas where Dengue Fever is present in mosquitoes, resulting in severe headaches, joint, muscle and bone pain and in some cases death. Australian scientists believe they may have the answer. When they injected mosquitoes with the Wolbachia bacterium, the insect was unable to transmit Dengue. 2011 tests proved optimistic when the bacteria was proved to be passed on through reproduction.
#28: Hepatitis B Boosts Malaria Vaccine
Past malaria vaccines haven’t shown great promise in trial, but a new GlaxoSmithKline test is showing a 50% success rate. The vaccine tricks the body into protecting against malaria by heightening the immune system via hepatitis proteins. With the trial running through 2014, we at Mosquito Squad are interested to see how it can help against Africa’s fight against malaria.
#13 Can Gut Bacteria Stop the Spread of Malaria
George Dimopoulos of Johns Hopkins University has found that the Enterobacter bacterium, when ingested by a mosquito, renders that mosquito unable to transmit malaria by killing a parasite that causes malaria. It was a happy mistake that hopefully leads to a cut in the number of malaria cases in future years.
2011 was a big year in the mosquito and tick world. Here’s hoping that 2012 brings the same, but as long as you are bothered by mosquitoes and ticks, Dread Skeeter and Mosquito Squad are here to protect you, your family and your friends.
Dengue Fever in Ocala and Miami – tips for travelers plus signs and symptoms
Posted by Robin Steele in Dengue Fever on July 27, 2010
Once thought to be a disease that had disappeared from the United States, as of July 2010, some cases are popping up in Ocala and Miami. The bad news is that the Aedes Aegypti mosquito is in the area of Southern Florida. More bad news is that due to how quickly mosquitoes breed, there are likely to be a lot more, very soon. But, there is good news. By watching out for symptoms of Dengue Fever, you can catch it and treat it before it becomes a danger to your long-term health.
Symptoms:
- severe headache
- joint, muscle and bone pain
- High fever
- severe pain behind the eyes
- rash
If these symptoms persist and you experience new symptoms like vomiting with severe stomach pain and possibly difficulty breathing you could be entering the next phase of the disease which is more serious. While there is no specific treatment for Dengue Fever, the symptoms can be treated effectively so they do not precipitate other health problems such as dehydration or uncontrolled high fever. If you think you may have Dengue Fever, contact a doctor for the next steps in treatment.
Prevention:
The only way to prevent Dengue Fever is to prevent mosquito bites. When stationary in such places such as a hotel or resort, try to find a hotel that treats their grounds for mosquitoes. In your home, have your yard sprayed by a professional which can eliminate most of the mosquitoes in your yard. When going out, use a topical mosquito lotion or spray. Be sure to check the safety of sprays before applying them to young children.
How does the yard spray program work? They spray your yard approximately every 3 weeks. The spray treatment is effective for that 3 week period. You don’t have to do anything. You don’t have to pick up the phone to schedule. You just sign up for the season and they take care of the rest. For commercial properties such as resorts and for special events such as weddings, they have seasonal and one-time event products to get rid of the nasty critters for your vacation or special day.
If you’re getting married at a coastline venue or at a water-location in their area, they can spray the area a couple days before to keep the pests away from you and your guests during the events. Mosquitoes breed in standing water so it’s a great idea to spray for your beach wedding, your lake wedding or other events near the water.
