Researchers Find Key Factors to Fighting the Dengue Virus

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.

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.

#47: Ending Dengue

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.

Are you letting the bedbugs bite?

Dread Skeeter fights the Mosquito and Tick bites

“Night, night sleep tight, don’t let the bed bugs bite”. The sweet, innocent bedtime saying many of us say to our children when it is bedtime. The elusive bedbug however is not so innocent. During the 1990’s the bedbug made a comeback.  The resurgence of the bedbug can be attributed to several reasons. Shifts in pest management play a role as well as resistance to certain pesticides. During the last ten to twenty years international travel has become commonplace allowing the bedbugs to hitch a ride so to speak on our clothing and luggage. We, as a society have also let our guard down to these resilient little bugs by thinking that bedbugs are a thing of the past.

Common bedbugs , their proper name being  cimex lectularius, were thought to have originated in the Middle east in caves inhabited by bats and humans. Bedbugs were mentioned as far back as 400 BC in ancient Greece. Bedbugs were a serious problem during World War II, General MacArthur actually commented that bedbugs were the “greatest nuisance insect problem….at bases in the U.S.”

With the introduction of more effective pesticides during the 1940’s the bedbugs nearly disappeared completely in Western countries. Bedbugs are parasites that are usually no more than 1/5 of an inch in length. Bedbugs feed on blood of humans and other animals. Bedbugs are nocturnal and most often feed when people are asleep. An adult female bedbug can lay up to 500 eggs during her lifetime. When a bedbug feeds it injects a salivary secretion to the bite to discourage coagulation, the secretion can cause itching and swelling. Although bedbug bites are not known to carry any human blood-borne pathogens, the bites can be painful, and can cause distress. Scratching the bites can lead to secondary infections and some people have been shown to have allergic reactions to the bites. Bedbugs reside and lay their eggs in your furniture, the box springs and folds of your mattress, they can hide in the cracks of your hardwood floors, in your carpet, behind pictures, in your luggage and even behind baseboards and other places in your home.

There are many ways to pick up bedbugs. One way is travel. Hotels, motels and resorts have a constant turnover of guests. You can bring them home unknowingly on and in your luggage and clothing. It is a common misconception that bedbugs thrive in filth, this is not true. Bedbugs can infest any type of dwelling. They can show up in luxury resorts as well as the cheaper “chain” hotels and motels. Bedbugs can also come into your home by way of infested furniture. Make sure any “second hand” furniture purchases from garage sales, consignment shops, antique shops and thrift store purchases are cleaned thoroughly before entering the home. Pets can bring the parasites into your home. People visiting from a source of infestation can also bring them into your home. People who live in nearby dwellings such as apartments and town homes can have the bedbugs come into their home by way of duct work if there are easy routes. Bedbugs are common with wild animals too, especially bats, rodents and birds. Bedbugs will often nest near animals that have also nested in a dwelling. A well fed bedbug can live anywhere from four to six months. A dormant bedbug can live without feeding for as much as 18 months. With the long span and capability of a dormant bedbug to lie dormant for that amount of time and emerge and begin to feed it is a good idea to make sure any items that you bring into your home and are unsure of their history should be inspected and thoroughly cleaned. An infestation of bed bugs can get out of control quickly with the number of eggs a female is capable of laying in her lifetime.

Now that you’re fully “grossed out” and probably itching just reading this article, you can fight the bedbug war. Detection of bedbugs is not as difficult as you may think. Even though these parasites are tiny, they still can be seen with the naked eye. They are experts at hiding however and are nocturnal and usually only come out at night. You can look for signs that you have an infestation by examining your mattress and bedding for any blood spots or brownish or reddish spots. These are called fecal spots. You can also sometimes identify an infestation by checking for evidence of their skins that have sloughed off during moulting. In severe cases sometimes a pungent odor is prevalent. This is a result of the oily liquid they emit. The most obvious of all the signs that you may have a bedbug infestation is the bite itself. The bites can be red and blotchy or welt like. Early detection is always a plus in helping control an infestation.

Knowledge is always power with the treatment of bedbugs. The best course of action once you have determined you have an infestation is to contact a professional. Remember that the bed is usually ground zero (hence the name), but it is not the only place they reside. It is a good idea to eliminate clutter around your home. Anything you deem is infected and decide to discard should be sealed and labeled so no one else will become infected. Mattresses and box springs that are being disposed of should also be labeled and sealed in the same manner for safe disposal.  Treatment will depend on how serious the infestation is and the range of action taken by the  professional could range from industrial vacuuming to heat treatments , encasement of  mattresses in plastic cover and /or the application of pesticides . Follow up visits may be necessary by your professional to ensure the problem is taken care of.

Like mosquito and tick bites, it’s good to be vigilant and take some time to inspect your bites. While bed bug bites are annoying and cause frustration and concern, at least they aren’t known to carry disease like mosquito and tick bites.

Remember, mosquito and tick bites can be prevented before they happen and in that case, prevention is the best cure. Have your yard sprayed on a regular basis during the spring, summer and early fall season. You can also take extra precautions against ticks by having an expert lay a product called tick tubes which animals will take back to their breeding and sleeping grounds.

Dengue Fever in Ocala and Miami – tips for travelers plus signs and symptoms

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.
