    PEAKS AND TROUGHS by Tim Baker The Random Blog

    Quote from andomhouseaustralia.wordpress.com
    The surfing world has been mourning the untimely loss of one of its greatest champions while celebrating the unmatched achievements of his fiercest rival.

    Irons was traveling home to Hawaii from the latest world championship event in Puerto Rico, having withdrawn due to illness. As has been widely reported, he had to stop over in Dallas due to his worsening condition, thought to be dengue fever, and was found dead in his airport hotel room the following morning. Tragically, his heavily pregnant wife Lyndie was awaiting his return and is due to give birth to their first child in December.

    FluTrackers - View Single Post - Puerto Rico: Dengue above epidemic threshold - 30 fatalities

    These numbers are pretty amazing. And, I continue to wonder just what the US is planning to do about those mosquitoes carrying this disease now in Miami, and Key West. This is not going away.

    Successful Experiment in Grand Cayman

    The Great Beyond: GM mosquitoes wipe out dengue fever in trial

    This article makes note that Brazil, where there have been recent cases of Chikungunya another mosquito born virus spread by this same species of mosquito, is interested in this technology.

    Quote from blogs.nature.com
    Traditionally, males are sterilised by exposing them to radiation. But A.aegypti proved to be highly sensitive to the radiation, to the extent that they were unable to compete successfully with their wild counterparts for mates. So instead the researchers decided to tweak the mosquitoes' genes to induce sterility. And it worked. The wild females liked the GM males just as much as their fertile counterparts.

    They released around 3.3 million sterile males over the 6 month study period, and found that the wild populations were reduced by 80% as a result - a level sufficient to effectively wipe out dengue fever in the area. "We saw a significant reduction in the target population", Luke Alphey chief scientific officer and founder of Oxitec said.

    Alphey said a number of other countries have expressed interest in the technology including Brazil, Panama and Malaysia, the latter of which will begin fields trials in the next few months. (SciDev.net; Malaysian government statement here.)

    Quote from www.staradvertiser.com
    The state Health Department is investigating 12 new cases of suspected dengue fever since a medical alert for the mosquito-borne viral illness was issued last week.

    "We tend to think it's not endemic," she said. "For the most part the cases are from elsewhere."

    The last Hawaii outbreak in 2001 sickened 153 people and was centered in Hana, Maui, with a few cases elsewhere on Maui and other islands.

    Four Locally Acquired Cases of Dengue in Oahu, Hawaii


    Quote from www.hawaiireporter.com
    This is a follow up from March 24, 2011, when the DOH confirmed two adults with locally-transmitted dengue fever and two suspected adult cases.
    "Based on a DOH investigation, the four adults appear to be related and were infected near their homes by mosquitoes on Oahu in the Pearl City area. All four individuals have recovered and are no longer ill," said Janice Okubo, spokesperson for the Department of Health.
    Okubo told Hawaii Reporter that the state is still waiting for lab results from the Center for Disease Control or still investigating a total of 23 reports of suspected dengue fever from Oahu physicians.

    I always wanted to go to Rio, but I would think twice about it because of this risk. Over 45,000 since January makes this a significant risk in my mind.

    Take a look at this map for a view of what areas dengue is likely to be found in. There are some surprises.

    East Maui, Hawaii


    Special concerns about those who have been previously infected as they are at greater risk for the more severe disease complications. Dengue can be very painful though not usually fatal however, if a re-infection occurs, it is very real possibility.

    Quote from www.mauinews.com
    Three new cases of dengue fever are suspected in Hana, along with a possible case in Haliimaile and an additional two or three Upcountry, according to health officials.

    In a meeting with Hana residents Tuesday night, Maui District Health Officer Dr. Lorrin Pang said at least one of two cases previously suspected in Keanae had been tentatively confirmed by a laboratory in Hawaii, although he was still waiting for official verification from a Centers for Disease Control and Prevention lab in Puerto Rico.

    ...they were concerned about the community's latest bout with the tropical disease - and were especially worried that people who caught dengue a decade ago would be at a higher risk for serious complications now if they were infected again.

    Visiting Haiti


    It is somewhat surprising that we have not heard of more cases of dengue coming in from Haiti considering the number of travelers coming and going from there. The concern, of course, would be that these cases not be be bitten by mosquitoes on their return to their home towns thus spreading the disease to a new location. This seems not to be a problem in Delaware as the specific mosquito type is not usually in the area.

    Quote from www.delawareonline.com
    Four people from New Castle County -- three adults and one 14-year-old -- who traveled to Haiti on a missionary trip are suspected to have contracted dengue fever, state health officials said.

    The missionaries, part of a group of 12, returned to Delaware July 9. It was unknown whether they were there to help with the relief effort from the January 2010 earthquake.

    The fever is spread through the bite of mosquitoes that are commonly found in tropic and subtropic regions, according to Medline Plus, the National Institutes of Health's patient information website. The specific mosquitoes that can spread dengue fever generally do not reside in Delaware, Patel said.

    Quote from www.cdc.gov

    Q. What is dengue?
    A. Dengue (pronounced den' gee) is a disease caused by any one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4). The viruses are transmitted to humans by the bite of an infected mosquito. In the Western Hemisphere, the Aedes aegypti mosquito is the most important transmitter or vector of dengue viruses, although a 2001 outbreak in Hawaii was transmitted by Aedes albopictus. It is estimated that there are over 100 million cases of dengue worldwide each year.

    Q.What is dengue hemorrhagic fever (DHF)?
    A.DHF is a more severe form of dengue infection. It can be fatal if unrecognized and not properly treated in a timely manner. DHF is caused by infection with the same viruses that cause dengue fever. With good medical management, mortality due to DHF can be less than 1%.

    Q.How are dengue and dengue hemorrhagic fever (DHF) spread?
    A. Dengue is transmitted to people by the bite of an Aedes mosquito that is infected with a dengue virus. The mosquito becomes infected with dengue virus when it bites a person who has dengue virus in their blood. The person can either have symptoms of dengue fever or DHF, or they may have no symptoms. After about one week, the mosquito can then transmit the virus while biting a healthy person. Dengue cannot be spread directly from person to person.

    Quote from www.osac.gov

    U.S. Embassy Nassau released the following Emergency Message for U.S. Citizens on August 9, 2011:

    U.S. citizens should be aware of the recent dengue fever outbreak in The Bahamas. In the past few weeks, over 200 cases have been reported and almost 1,000 cases have been reported of individuals suffering from symptoms that match dengue.

    The Ministry of Health has begun spraying local communities, especially the more densely populated areas, and they have stressed to the public the importance of prevention.

    The local government continues to combat this outbreak through greater public awareness of dengue and the importance of mosquito control.

    Second Locally Acquired Dengue Case in Miami

    Local Man Diagnosed With Dengue Fever | NBC Miami

    No vacation to exotic places required. You can get dengue right at home in Miami.

    Quote from www.nbcmiami.com
    A 44-year-old man is the second person to get Dengue Fever in Miami-Dade County this year, local health officials said Wednesday.

    The man has fully recovered, but laboratory results confirmed he had Dengue Fever.

    It is a viral disease transmitted by a mosquito, and it is not spread from person to person, officials said. Symptoms include fever, severe headache, severe pain behind the eyes, muscle, joint and bone pain.
