• Satellites could predict next cholera outbreak

    With cholera making an unlikely resurgence, catching countries like Haiti and Pakistan by surprise, public health officials are exploring the potential for new technology to help stem the spread of future outbreaks; each year the disease affects three to five million people and claims more than 100,000 lives; researchers believe that satellite images of oceans could help forecast when a cholera outbreak is likely to strike

  • Natural antibody brings universal flu vaccine closer

    Annually changing flu vaccines with their hit-and-miss effectiveness may soon give way to a single, near-universal flu vaccine, according to a new report from scientists at the Scripps Research Institute and the Dutch biopharmaceutical company Crucell; they describe an antibody which, in animal tests, can prevent or cure infections with a broad variety of influenza viruses, including seasonal and potentially pandemic strains

  • 100 Utah employees quarantined after measles outbreak

    A measles outbreak has forced a power plant in northern Utah to keep hundreds of its employees at home; last week an employee at the Intermountain Power Agency power plant in Delta, Utah tested positive for measles prompting officials to order an estimated 100 employees and contractors born after 1957 to stay home until they can show that they have been fully vaccinated

  • "Networking" turns up flu virus tied to 2009 pandemic

    Scientists using new mathematical and computational techniques have identified six influenza A viruses that have particularly close genetic relationships to the H1N1 “swine” flu virus that swept through the United States beginning in the spring of 2009; that virus eventually killed almost 18,000 people worldwide

  • Method used in hunting serial killers can be used against killer diseases

    Geographic profiling, a method used in the hunt for serial killers, can help combat infectious diseases; the statistical technique uses the locations of crimes to identify areas in which the serial criminal is most likely to live and work; it was originally developed to help police prioritize suspects, but can now be used to map the locations of diseases to try and identify the source of the disease

  • Fate of last smallpox virus samples to be determined today

    The World Health Organization officially declared in 1979 that smallpox has been eradicated; in the three decades since the WHO declaration, the Centers of Disease Control and Prevention (CDC) in Atlanta, Georgia, and a Russian government laboratory near Novosibirsk have been the last two places to keep samples of the smallpox virus; during this time, there have been many calls by scientists and advocates to destroy these last samples — some of these calls accompanied by dark hints that the two countries wanted to hang on to the samples in order to use them as a basis for a future bio-weapon; the United States opposes the destruction, saying that the live samples are needed to develop vaccine with less adverse side effects as well as two other related drugs; a committee of the World Health Organization is meeting today in Geneva to make a decision

  • Secrets of plague unlocked with stunning new imaging techniques

    Sandia Labs researchers have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell’s defenses fail against some invaders, such as plague, while successfully fending off others like E.coli

  • California schools struggle to vaccinate millions against whooping cough

    After experiencing its worst whooping cough outbreak in more than six decades, California is taking extra precautions to ensure that children are vaccinated against the preventable disease; California lawmakers mandated that all children entering the seventh grade and up must have a whooping cough booster vaccine; but parents and school districts are still scrambling to get children vaccinated before the Fall when students will be prohibited from entering a classroom without it; nearly three million students must be vaccinated making it a logistical nightmare for schools to process paperwork; in 2010, there were than 7,800 cases of whooping cough and the disease claimed the lives of ten children

  • Satellite information helps eradicate mosquitoes

    Louisiana’s St. Tammany Parish is partnering with Colorado-based location intelligence software company aWhere, Inc. to test a new satellite-based surveillance system that can locate and analyze potential mosquito breeding sites with near pinpoint accuracy

  • Superbug sweeps across Los Angeles hospitals

    Last week, public health officials in Los Angeles reported an outbreak of a drug-resistant superbug in several local healthcare facilities; the deadly drug-resistant strain is Klebsiella pneumonia (CRKP) and is estimated to kill 40 percent of those who are infected with it; the LA county health department has identified 356 cases of the bacteria over a six month period; CRKP has primarily been infecting senior citizens; CRKP is part of a larger wave of antibiotic germs that have plagued hospitals in recent years; the bacteria was originally found on the east coast of the United States, and was only first seen last year in the Los Angeles area

  • Canada launches TB website to stem spread of disease

    Researchers at Canada’s McGill University recently launched a free website to help doctors around the world stem the spread of tuberculosis (TB); the website offers detailed information on TB vaccinations in over 180 countries; while TB levels are at all-time lows in Canada and the United States, TB has grown increasingly prevalent around the world particularly in Africa and India; in India, there are nearly two million new cases of TB each year and it is the leading cause of death among people between the ages of fifteen and forty-five; the International Federation of Red Cross and Red Crescent Studies recently warned that up to ten million people could die of TB by 2015; if detected early, TB can be treated with antibiotics

  • Australia battling mosquitoes to stop spread of dengue fever

    Public health officials in Queensland in northern Australia are actively battling dengue fever following an outbreak of the virus; fifty-five people have been infected in Innisfail and its outlying areas; two cases of dengue fever have been detected in Cairns, 56 miles north of Innisfail; to stem the spread of the disease, public health officials are on a campaign to eradicate mosquitos and their breeding grounds; so far the government has wiped out an estimated 50,000 mosquito breeding sites; in one week, fourteen public health field officers searched 1,117 properties in Innisfail and found 13,628 potential breeding sites

  • Controversy of Kansas biosecurity lab continues

    KSU attracted the $650 million National Bio and Agro-Defense Facility for making vaccines and anti-virals to combat the world’s most dangerous animal diseases, beating out the competition during a multi-year screening process; in addition, KSU is planning a 26 April open house for a brand-new “innovation campus” west of Kansas City that will provide graduate level and professional science master’s degree programs (targeted versions of traditional academic programs) as well as industry training in animal health, food safety, and bio-security for more than 120 companies located in the “Kansas City animal health corridor”; critics say that building such a lab in Kansas — one of the largest livestock producing states, and a state which lies at the nation’s transportation crossroads and in the middle of Tornado Alley — is not such a good idea

  • Ticks identified as cause of lethal disease in China

    In 2006 villagers in Anhui Province in central China began dying of an illness characterized by high fever, gastrointestinal distress, and a depressed platelet count; researchers suspected anaplasmosis, an infection spread by ticks caused by the bacterium Anaplasma phagocytophilum – but they found neither bacterial DNA nor antibodies against it; each spring since then the disease has struck with a vengeance, killing up to 30 percent of those infected in six provinces of China; scientists have now identified the enemy

  • Cholera outbreak in Haiti projected to infect twice as many people

    U.S. researchers fear that Haiti’s cholera epidemic could be far worse than initially projected; new models estimate that nearly 800,000 people will be infected with cholera, almost double initial estimates; nine months after the 7.0 magnitude earthquake that shook Haiti last year, cholera cases began to appear for the first time in nearly a hundred years; public health officials are currently debating how to stem the spread of cholera by pursuing vaccination, antibiotics, or sanitation; Harvard researchers are advocating for the use of all three
