Study suggests new approach to dengue fever

Dengue fever may be more than three times more prevalent than current estimates, according to a new report. 

The study, led by researchers at the University of Oxford in England, estimates there are 390 million dengue infections around the world each year. Currently, the World Health Organization puts the number between 50 and 100 million infections each year. Researchers hope their findings will help pinpoint parts of the world most vulnerable to dengue fever and develop strategies to treat it.

Dengue fever is passed from person to person by mosquitos. Unlike malaria, there are no drugs you can take to avoid getting it. It also is difficult to treat and thus far, attempts to develop a vaccine have been unsuccessful. 

Map: Areas in red indicate high risk for dengue occurrence, while green areas indicate low risk.

It is most common in Asia and India, but more cases have been popping up in the Caribbean and Latin America in recent years. In mild cases, dengue fever causes a high fever, rash and joint and muscle pain. In extreme cases, it can cause death. According to the World Health Organization, about 12,000 people die of dengue fever each year. Many of them are children.

For this research,  a team of international experts developed a statistical model based on things like temperature, humidity and even newspaper reports, to figure out where dengue was most likely to show up. Then, they combined that information to develop a map, down to precise 5-by-5 kilometer regions where outbreaks were most likely to occur.

"This helps us make a decision on where we prioritize efforts to reduce the burden of disease," says Tom Scott, a researcher at the University of California, Davis, and one of the authors of the report. By 2015, the WHO wants to reduce deaths from dengue fever by 50%. 

"It's really doable," says Scott.  "These maps could help direct that."

But some experts take issue with the study's numbers and say the estimate is too high. 

"Dengue is extremely complicated," says Dr. Scott Halstead, who has been studying the disease for over 50 years and is the senior scientific advisor to the Dengue Vaccine initiative at the Bill & Melinda Gates Foundation. 

He points out the numbers for Africa.  "A disease resistance gene in Africa has been well established, which suggests the disease burden in Africa  is overestimated," says Halstead.

The study is published in the current edition of the journal Nature.

    If you receive one, you can check for the information of the girl and decide
    to what to reply by sending an email according to your likes and dislikes.
    Any kind of information can personify searched very fast, often in an prompt.
    Except you can pay for a authentic pony for your youngsters, then that's the time to private an individual.

    Now they have live shows and also have branched out to pay per scene
    which is a big money maker these days for customers that don't want to sign up
    for a monthly subscription. Many years ago when online dating websites were launched, the majority if not all the online
    dating websites were based on pay to use. The
    video games extensively use the 'drag' feature to permit gamers to just drag and drop or drag and use
    the available play instruments on the game website.
    Even so, in the case that your sister (or sisters)
    had been mean to other players and you, you and other gaming fans weren't
    so fortunate, or were other gamers and you? When the ponies are dressed-up,
    performed with makeup, the gamers can click on on the 'go to show' button so they can participate in the styling

    We couldn't be happier to offer you an experience like this, as full featured as
    this, with as much variety as this, completely free of
    charge. You've never seen anything like this, trust us.
    Sites like Chaturbate (often mistakingly
    written as Chaterbait) are great for having fun with other adults on free cams.
    It should just be an emoji of two people having sex or an automatic
    geo-locator, because the only texting that’s not sexually-based on this app is "Where are you? It takes some clout to make up words and expect people to use them, but if you’re big enough, anything is possible. There’s a SEND TIP button, so if you’re not freeloading, you can show the talent some appreciation. The show hasn’t even started! This is the place where you can realize your every fantasy and even create new ones. Free servers are often slower, and since most are ad-supported, they place adverts on the online pages you access.

    That's not an experience I know, but as an Australian living in America at the
    time, it spoke to me. The experience can be awesome and is truly amazing.

    The second installment in Disney's Frozen juggernaut proves that animated movies - and sequels - can still make best-of lists.

    But Captain Marvel isn't one of my 2019 favorite films just because it gets girls and women right, showing you can be
    strong and emotional and still kick butt. Even looking back at this trip, I still get this feeling.
    Right now I’m thinking I’ll tell her a few days ahead of
    time that I’m going on a trip to see the doctor and that
    I’ll have a Band-Aid on my neck when I get back.
    When she had suffered concussion previously, her doctor's advice was to take
    it easy for a few weeks before returning to play. For anyone who has suffered through
    endless fad diets with zero results - this movie will change your life for the
    better. Read on to find out how an appreciation for the water
    can positively impact a child's life in all so many ways.
    It's a film that lingers in the corner of your mind
    as you find yourself wondering how the hell they shot certain parts,
    replaying monologues and drunken arguments in your head, resurfacing shots that perfectly pair the repulsive and beautiful.

    Other sites have restriction for models, they can’t be
    nude in front of camera, and they can only do that in a
    private show. The Customer Support Team can be contacted only via the feedback form.

    The website demands that the models must meet
    specific qualifications before they are admitted to
    the team. If you are maybe experienced chaturbate cam girl and you think I
    forgot something to mention, please let me know in the comments.

    In order to understand how to best support webcam workers, we have
    taken a detailed glimpse at how such a sex service looks like from the perspective of
    cam sex models. Around your bra, girls fingering
    on webcam handle it, imagined. Try to differentiate yourself from other Chaturbate
    cam girls. Try to offer something new to your visitors from time to time.
    Over 50 000 visitors are on this site every moment, and chance for someone to visit your chat room is huge.
