    Scientists are scrambling to make sense of a sharp increase in reported infections with the deadly Middle East respiratory syndrome (MERS) virus. In April alone, Saudi Arabia and the United Arab Emirates have reported over 200 new cases—more than all MERS-affected countries combined in the preceding 2 years. That has sparked fresh fears that the virus may be about to go on a global rampage. The World Health Organization expressed alarm at the new numbers, and the European Centre for Disease Prevention and Control (ECDC) published an updated risk assessment on 25 April warning European countries to expect more imported...

    Over a one-year period, five children in California developed a polio-like illness that caused severe weakness or paralysis in their arms and legs, a new case study reports. In two of the children, their symptoms have now been linked with an extremely rare virus called enterovirus-68. Like the poliovirus, which has been eradicated in the U.S. since 1979 thanks to the polio vaccine, strains of enterovirus in rare cases can invade and injure the spine. These are the first reported cases of polio-like symptoms being caused by enterovirus in the United States. During the last decade, outbreaks of polio-like symptoms...

The studies suggest that the viruses—one of which also widely circulates in animals in Vietnam—could be involved in brain inflammation and paraplegia, but further studies are needed to confirm a causative link. The discovery in Vietnam grew out of a frustrating lack of information about the causes of some central nervous system (CNS) infections such as encephalitis and meningitis, which...

But these protein nanoparticles are science's latest weapon against influenza: a new breed of flu vaccine that provides better and broader protection than commercially available ones — at least in animal tests. Current flu vaccines use inactivated whole viruses and must be regularly remade to target the strains most likely to cause illness in the coming year. But the new nanoparticles would require fewer updates because they induce the production of antibodies that neutralize a...

    Northwestern Medicine scientists have identified a component of the herpesvirus that "hijacks" machinery inside human cells, allowing the virus to rapidly and successfully invade the nervous system upon initial exposure. Led by Gregory Smith, associate professor in immunology and microbiology at Northwestern University Feinberg School of Medicine, researchers found that viral protein 1-2, or VP1/2, allows the herpesvirus to interact with cellular motors, known as dynein. Once the protein has overtaken this motor, the virus can speed along intercellular highways, or microtubules, to move unobstructed from the tips of nerves in skin to the nuclei of neurons within the nervous...

    First of the parasitic parasites to be discovered in a natural environment points to hidden diversity. A genomic survey of the microbial life in an Antarctic lake has revealed a new virophage — a virus that attacks viruses. The discovery suggests that these life forms are more common, and have a larger role in the environment, than was once thought. An Australian research team found the virophage while surveying the extremely salty Organic Lake in eastern Antarctica. While sequencing the collective genome of microbes living in the surface waters, they discovered the virus, which they dubbed the Organic Lake Virophage...

    TRANSITIONAL ORIENTATION The last days had dwindled down to a final few. Evil was moving and extremely confident while Good was leaderless. The Middle East was in turmoil and Evil was now in position to finally achieve its only goal - the destruction of mankind. That destruction was to start, to no one's surprise, with the annihilation of Israel. Annihilation was now portable. A few travelers to whom death was an honor would deliver suitcases filled with devices of ultimate horror. Those suitcases had been gathered and assembled from around the world by a cabal that transcended race, religion, culture...

    THE THIRD WAVE Sympatric Speciation In 2003 a retired biologist took the lead position in sounding the alarm about SARS. Her work would include redefining how information is exchanged in the digital age, educating professionals and laymen alike and creating the new media phenomena now known as the “Flu Blog”. She would later go on to accurately describe the natural host of the Ebola Virus – five years before confirmation of her hypothesis was published. I was fortunate enough to interview her on a wide variety of topics. That conversation has lasted several years. The first four discussions are linked...

    U.K. Study Overturns Previous Research Citing Virus as Cause of CFS Reviewed by Rob Hicks, MD Chronic fatigue syndrome is not caused by the virus XMRV, according to new research. A team from University College London, the Wellcome Trust Sanger Institute, and University of Oxford, all in England, says previous research linking the virus to chronic fatigue syndrome (CFS) was flawed because of contamination of mouse cell DNA samples in the laboratory. CFS is a disorder characterized by chronic fatigue lasting six months or longer, with several additional symptoms that may include impaired memory, unrefreshing sleep, muscle pain, sore throat,...

    There has been much discussion by national security experts inside and outside of government as to how Congress and the President should ensure that the United States is safe from a terrorist attack.  But there has been relatively little discussion in comparison as to how we would respond if an attack did occur.  Are we ready for a biological attack on our military or citizenry?  Has the federal government planned for a medical response to an attack?  Are we spending money on the right therapies or vaccines?  Do we even know how to respond to a widespread biological or chemical...

    A new kind of compound to treat hepatitis C is showing promise in early clinical trials. The treatment, being developed by Bristol-Myers Squibb (BMS), was found to be very effective at lowering viral load, both in a Phase I trial published this week in Nature, and in early results of a Phase IIa trial presented at the European Association for the Study of the Liver's annual meeting in Vienna last week.Current HCV therapy is not ideal. The standard treatment is with an interferon and the antiviral agent ribavirin, but is only effective in around half of all patients and is plagued with...

    Cell-culture and animal tests show antiviral could provide protection against HIV, Ebola, hepatitis C, herpes and moreGALVESTON, Texas — The development of antibiotics gave physicians seemingly miraculous weapons against infectious disease. Effective cures for terrible afflictions like pneumonia, syphilis and tuberculosis were suddenly at hand. Moreover, many of the drugs that made them possible were versatile enough to knock out a wide range of deadly bacterial threats. Unfortunately, antibiotics have a fundamental limitation: They're useless against viruses, which cause most infectious diseases. Antiviral drugs have proven far more difficult to create, and almost all are specifically directed at a few...

    By AP Medical Writer ATLANTA (AP) - Scientists have identified a lethal new virus in Africa that causes bleeding like the dreaded Ebola virus. The so-called "Lujo" virus infected five people in Zambia and South Africa last fall. Four of them died, but a fifth survived, perhaps helped by a medicine recommended by the scientists. It's not clear how the first person became infected, but the bug comes from a family of viruses found in rodents, ... "This one is really, really aggressive" he said of the virus. ... A paramedic in Lusaka who treated her also became sick, was...

    Lab results could explain why young patients are hardest hit by current H1N1 strain. Antibodies against some seasonal flu strains from prior years may be active against the new H1N1 swine flu currently circulating the globe, a recent study reports. The findings suggest an explanation for why swine flu appears to infect the young more often than the elderly, who are normally more susceptible to seasonal flu viruses.Only 1% of swine flu cases in the United States are in people over the age of 65.CDC The study, published today in the Morbidity and Mortality Weekly Report, analyzed blood samples taken...

    Components have existed for years but are combined in a new way Components of the H1N1 swine flu virus have been circulating undetected for years, but the virus combines the bits and pieces in a way never before seen, a detailed genetic analysis reveals. The analysis, published online May 22 in Science, pinpoints the origins of each of the virus’s components. It suggests that current influenza vaccines probably won’t provide protection from the virus, but that the virus is susceptible to some antiviral drugs and will be amenable to new vaccine development. A separate study of the virus’s neuraminidase protein...
