Dengue reappears in the United States

A study released Tuesday by the Centers for Disease Control and the Florida Department of Health finds dengue virus is showing up in the Florida Keys.  According to the report,  approximately 5 percent of Key West residents, or about 1,000 people, were exposed to it in 2009.  So far this year, there have been 12 confirmed cases of dengue in the Key West area.  The last time there was a dengue outbreak in Florida was 1934.

""These people had not traveled outside of Florida, so we need to determine if these cases are an isolated occurrence or if dengue has once again become endemic in the continental United States," said Harold Margolis, chief of the dengue branch of CDC in a press release.  "We are concerned that if dengue gains a foothold in Key West, it will travel to other Southern cities ... like Miami."

Dengue is the most common virus transmitted by mosquitoes in the world.  It causes up to 100 million infections and kills 25,000 people every year.  Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas, according to the World Health Organization.

Symptoms include high fever, severe headache, severe pain behind the eyes, joint pain, muscle and bone pain.  There is no vaccine to prevent dengue, but early detection and treatment can reduce the risk of severe illness. Locally acquired dengue outbreaks in the United States are rare.  There have been a few confirmed cases along the Texas-Mexico border in recent years.

    this may be the best thing to ever happen to those who live in areas affected by dengue. we might actually see a vaccine or the like now. not that having people sick is ever good...and it is s*** timing eh. i dont really know what my point is anymore

      So, since it's been seen in the Florida Keys a vaccine will now magically appear?

      HAHAHAHAHA!!! Funny.

      This has been killing people all over the world for eons, but now that it's been seen in mainland USA it's important enough for a vaccine.

      The USA has been experiencing this all along. Or rather, it's tropical territories have: Puerto Rico, Virgin Islands, Guam... but I guess the people living there are not important enough for you.

      wow mr bo you sound like a total d***. well if you look into it you will see that much, much less is spent on flaviviruses than others. the reason they are underfunded is because they tend to afflict hot, equitorial regions (meaning poor). mentioning aids is redundant because it is an ungodly bastard of a virus that has only been well known for 30 years. basically i wasnt trying to say its a good thing but it may result in treatment.

      It is not that we can not make a vaccine... it is the problem with Dengue itself. There are 4 variants of Dengue and it is normally ok to get afflicted with one of them (typical flu-like symptoms). However, the real problem becomes when you are afflicted by a 2nd or 3rd different version at a later date in life. This causes a massive immune memory response which can potentially cause death. Therefore, many people throughout the world have been working on a safe tetra-variant vaccine. Otherwise, you would just be setting people up for a dangerous situation if you used only 1, 2, or 3 of the variants in a vaccine.

      1. There are three serotypes of Dengue virus.
      2. While an immune reaction does develope from infection it does not protect against the other strains.
      3. Unique feature of Dengue is that if you have been exposed to one strain and subsequently are exposed to a different strain you will most likely develop a hemorrhagic form of the disease, think EBOLA. This is most often fatal.
      4. It was wiped out in the US but is epidemic in other parts of the World. If it becomes wide spread here it will have very deadly impacts on the population and dramatic impacts on the health care system.
      5. We need to secure our borders, re-institute Quarantine of persons entering the US to prevent the entry of novel diseases, think West Nile Virus. We used to have Malaria endemic to the US as well, heaven help us if it gets reintroduced. We can not afford to allow open entry and travel into this country in the face of diseases for which we have no treatment or immunity. "Read the Coming Plague"

      You can get 4 strains of dengue, I suffered 3 of them, one I caught overseas but got sick while in Miami. Dengue used to be "common" as high as Georgia, it was called "breakbone fever". It's very debilitating, you bleed easily and could actually kill you.

      To play Devil's Advocate, just think what it would be like if Malaria were cured and those 2M people DIDN'T die each year? They would die from war and starvtion as they fought over vanished resources. Plagues should be controlled only when the human population has demonstrated control over itself. The sad thing is the technology is readily available and cheap but cultural factors in many regions still promote constant birthing. I would donate large sums to Feed The Children and other agencies if they also mandated 5 year birth control for the women in receiving families. Feeding their kids allows them to birth even more, who also become dependant.

    The movement of dengue north is a consequence of global warming.

    Get ready, America. As the US warms, other disease carrying mosquitoes will survive and thrive in new places farther north.

      Years ago, scientists predicted a moving northward of tropical diseases, such as malaria and dengue fever, due to global warming. We're now living that reality.

      As the climate warms, these tropical diseases will spread even further northward.

      There will be more most definitely. Mexico is full of it and it abounds during hurricane season, which is now. Better start checkin' California now too. Americans are not familiar with it and neither are many of its doctors, making diagnosis harder as it normally wouldn't come to mind as a possibility. Mexico has health care, a socialized form, they fumigate against it (I don't want to know with what, they were still using DDT last I knew of), and they also provide public service messages on how to try and curb it – by getting rid of any standing water.

I couldn't hold down solid food at all. 17 days straight without being able to eat, and I dropped from 165 to 120 pounds. And the thought that it could become hemorrhagic if another another variety infects me? This disease bites.

    I had dengue in 2007 when I was living in Kiribati. I woke up in the middle of the night and felt like I'd had the crap kicked out of me. Every bone in my body hurt and I was freezing cold (it was at least 85 F). When I called a dr. I was told to drink plenty of fluids, rest, and take Tylenol if I had any. If I started noticing blood pockets under my skin to call again because I was probably hemorrhaging internally. I felt like crap for about a week and was pretty weak, but then it passed. The only people I knew who died were elderly, babies, and people who refused to stay hydrated. Put on your bug spray or stay inside at dusk the mosquitoes are at their worst. People in CA have to deal with earthquakes, the Midwest has tornadoes, the price you pay for living close to water is mosquitoes.

    Listen up newbies: Dengue is a VIRAL fever...no vaccination exists for prevention. The vactor (carrier) is Aedes aegypti, a mosquito. Signs and symptoms include: (7 days post bite) sudden high fever and intense headache, rash, severe joint and muscle pain (break bone fever), apparent recovery then perhaps return of signs and symptoms leading to recovery. Approximately 1 wk in duration. Painful, but mild and rarely life threatening BUT may progress to lungs: hemmorrhage,shock,death.. May be disruption of clotting factors leading to uncontrolled bleeding and shock. Severe vomitting, dermal capillary hemorrhage=rash, possible death within hours (mostly in SE Asia)...possibly due to hypersensitivity reaction when memory cells encounter the virus a 2nd time.

      Small correction, VECTOR, not vactor. Sorry, a bit anal retentive on professional discourse...
      Another thing dengue fever is called is "Break bone fever", due to the intense pain caused by the illness.
      As far as considering it being downplayed in your writing, remember that it IS considered as a potential biological weapon for a reason. While it usually doesn't cause many deaths, the disability caused by the illness can disable an economy in a region where it becomes epidemic.
      Personally, I'll take another infection with west nile.
      And I'm being trite with that, millions have already been infected with west nile virus and never realized that the "summer flu" they had was WNV (I'm sero-positive for exposure).

    Dengue is awful. I have never felt so sick in my life as I did when I contracted dengue fever (in Thailand). The muscle pain was so severe that I felt like my bones were breaking (hence the old name for dengue–bone break fever), and it took me weeks to fully recover my strength. I pray that I never contract another strain and encounter dengue's evil twin–dengue hemorrhagic fever. I had a friend get seriously ill (to the point of near death) after contracting a second strain of dengue after a previous infection months earlier.

    Pay special not to the last line in the article,
    "There have been a few confirmed cases along the Texas-Mexico border in recent years."

    A disturbing coincidence was an article I read a few days ago detailing how the Taliban are assisting the drug smugglers along the Texmex border. You suppose they brought some of that crap with them?

    One of the biggest fears regarding swine flu was that it might cripple the nations economy by knocking out too many related industries at one time. Example, truckers who deliver our food frequent a great many truck stops along the way. If too many truckers got sick at the same time, it could disrupt the food supply system. Or gasoline shipments. Or the people who monitor the electric grid. That is just a few examples.

    This is just the U.S. government's plot to finally put down the Conch Republic. Long live the C.R.

    nursehope, are you saying that a vaccine can't be made because dengue is VIRAL??? Isn't the flu viral, something we get vaccinated for each and every year? That's how you made it sound anyway...

    Dengue fever is serious but preventable. Mesquito control, netting, replellants all can minimize the chances of getting dengue. We should be more concerned about TB. TB has developed a resistance to most drugs in 3rd world countries. The USA is screening immigrants very thoroughly to prevent its introduction into the US. The real issue is that illegals circumvent the health dept screeing for legal immigrants. A school in Orlando, Fl had a TB scare when one of the illegals was found to have TB and needed treatment. How many other students were exposed to the anti-biotic strain of TB by this illegal student and his family?

    Dengue fever appears to have a mortality rate of 0.025%. That is better than the flu. So while it makes folk really sick, I am not going to panic about this.

    Nursehope – yes vaccines do exist for viruses – flu, measels, mumps, rubella, chickenpox – all viruses, all with vaccines.

    I have been in a fellowship for the past few years working specifically on the Dengue virus and its 4 serotypes. There has not been a lack of scientific progress on the virus as well as potential vaccines or treatments, but the virus itself is a huge hurdle. Anytime someone gets infected with one serotype of the virus it ellicits an antibody response. If a person is then subsequently infected with another serotype, the body's antibody response from the first infection is not only useless against the second, but aids in its proliferation in a phenomenon known as antibody dependent enhancement (ADE). With the development of a vaccine, it would be impossible to give all 4 serotypes of the virus since there are different substrains of each serotype. So instead of a fever and muscle aches, the first infection of a vaccinated person would cause the severe form of dengue hemorrhagic fever or dengue shock syndrome, both are potentially fatal. There are research teams throughout the country and the world that have been scrambling for years upon years to understand the virus as well as find a cure or vaccine. This is not a political issue, but a scientific one.

    I hate mosquitoes! I've been taking bite-amins this past month and hardly had a single bite (www.bite-amins.com).

    I live in Key West. My mother, who just turned 50 contracted dengue in May. In May she was in the ICU for a week and suffered a secondary infection that also affected her brain. She says she now has trouble coming up with words–she is the family Scrabble Pro...so I am worried of long lasting damage that may have been done. The doctors did not confirm the dengue infection until last week, which still baffles me.!
    For the record: I do not blame immigrants, I blame tourists from cruise ships!

      I'm so sorry to hear about your mother. I research dengue and the Ae. aegypti mosquito that carries the virus. I've been able to meet with many of the patients who've contracted dengue this year since April throughout Old Town, and I know mosquito control as well as the Monroe County Dept. of Health are doing every they can to contain the situation. Unfortunately, despite abatement efforts those mosquitoes can reproduce fairly quickly and very little water is necessary (and during the rainy season, it's easy to come by). It's imperative that every effort be made by home owners/renters to assess their property for water holding containers, dump any standing water to prevent breeding, and if they come down with a fever to see their primary care physician for confirmed blood test diagnosis.

      My best to your mother for a continued recovery.

    There is a solution to this problem, its called DDT. But society has deemed birds more important than people, so this is what we get. It seems like there should be a way to reconfigure the molecule to still be effective, and not effect egg shells. If we can spend billions on global warming, couldn't we spend a little on this?

      I'm afraid you are incorrect. Yes, the impact of DDT had caused a stir among environmental groups back in the 1960s with the release of Rachel Carson's Silent Spring. However, the discontinued use of DDT was NOT because of those effects on non-target organisms, but rather because the organochloride was ineffective as an insecticide; the mosquitoes were becoming resistant to it. Insecticide resistance is one of the main hazards that come with attempts at mosquito control. It is necessary for those abatement operations to cycle different chemicals in order to avoid such events. Many countries still use DDT, and many countries in Africa are looking to use it again, sparingly, as indoor residual spray to combat the vector, but resistance is still a factor in its prolonged use.
