• EpidemicsBolstering international response capabilities to infectious disease threats

    To make the world safer against future infectious disease threats, national health systems should be strengthened, the World Health Organization’s emergency and outbreak response activities should be consolidated and bolstered, and research and development should be enhanced, experts say

  • EpidemicsHow will the next leader of WHO tackle future health emergencies?

    In light of heavy criticism of the World Health Organization’s handling of the Ebola outbreak, the election process for the next director general will be under intense scrutiny. Experts outline the key questions on epidemic preparedness for prospective candidates.

  • EpidemicsYellow fever epidemic threatens new global health emergency

    Evidence is mounting that the current outbreak of yellow fever is becoming the latest global health emergency, two experts say, calling on the World Health Organization (WHO) to convene an emergency committee under the International Health Regulations. In addition, with frequent emerging epidemics, they call for the creation of a “standing emergency committee” to be prepared for future health emergencies. The add that vaccine “supply shortages could spark a health security crisis.”

  • EbolaCellphone-sized device detects the Ebola virus quickly

    The worst of the recent Ebola epidemic is over, but the threat of future outbreaks lingers. Monitoring the virus requires laboratories with trained personnel, which limits how rapidly tests can be done. Now scientists report in ACS’ journal Analytical Chemistry a handheld instrument that detects Ebola quickly and could be used in remote locations.

  • CholeraHaiti’s cholera epidemic could have been prevented with low-cost approaches

    Haiti’s cholera epidemic killed close to 9,000 people and hospitalized hundreds of thousands more. The epidemic also spread to several neighboring countries. Cholera remains a critical risk for UN peacekeeping operations, years after Nepalese troops inadvertently introduced the disease to Haiti in fall of 2010 and triggered one of the worst epidemics in recent years. Researchers have found that simple and inexpensive interventions — which the United Nations has yet to implement — would be effective in preventing future outbreaks of the bacterial infection.

  • EbolaEfficient alternative for Ebola screening program for travelers

    As of 31 January 2016, a total of 28,639 cases and 11,316 deaths have been attributed to Ebola, figures that are assumed to significantly underestimate the actual scope of the 2014 Ebola Hemorrhagic Fever outbreak in West Africa. In the United States, there were also two imported cases and two locally acquired cases reported in September-October 2014. Researchers offer an alternative policy for Ebola entry screening at airports in the United States. “Security measures implemented after 9/11 taught us a lot about what not to do,” one of the researchers say. “We learned that finding the one person who intends to do harm out of several million passengers is akin to finding a needle in a haystack.”

  • EbolaEbola no longer a “Public Health Emergency of International Concern”: WHO

    On Tuesday the WHO officials met to consider the Ebola virus disease (EVD) outbreak in West Africa, and to decide whether the event continues to constitute a Public Health Emergency of International Concern (PHEIC) and whether the current Temporary Recommendations should be extended, rescinded, or revised. WHOconcluded that Ebola transmission in West Africa no longer constitutes an extraordinary event, that the risk of international spread is now low, and that countries currently have the capacity to respond rapidly to new virus emergences. Accordingly, the Ebola situation in West Africa no longer constitutes a Public Health Emergency of International Concern, and the temporary recommendations adopted in response should now be terminated.

  • Health emergenciesSharing of research data, findings should be the norm in public health emergencies

    Opting in to data sharing should be the default practice during public health emergencies, such as the recent Ebola epidemic, and barriers to sharing data and findings should be removed to ensure those responding to the emergency have the best available evidence at hand, experts say.

  • PlagueIdentifying areas of plague risk in Western U.S.

    Plague was first introduced into the United States in 1900, by rat–infested steamships which had sailed from affected areas. Epidemics occurred in port cities, with the last urban plague epidemic in the United States occurring in Los Angeles from 1924 through 1925. Researchers have identified and mapped areas of high probability of plague bacteria in the western United States. The findings may be used by public health agencies to aid in plague surveillance.

  • Pubic healthFlu season likely to peak in February

    According to the CDC, seasonal influenza affects up to 20 percent of people in the United States and causes major economic impacts resulting from hospitalization and absenteeism. The flu season will likely peak in February in most parts of the United States, according to a model developed by scientists at Los Alamos National Laboratory. Using historical data, a mathematical representation of how flu spreads through a population, and data for the current flu season provided by the Centers for Disease Control and Prevention (CDC), the scientists were able to create a probabilistic model forecasting the flu season.

  • EbolaU.S. capability for treating Ebola outbreak sufficient but limited

    The United States has sufficient capacity for treating another outbreak of the Ebola virus, but financial, staffing and resource challenges remain a hurdle for many hospitals and health systems attempting to maintain dedicated treatment centers for highly infectious diseases, according to new study.

  • EbolaPlant virus to make Ebola detection more accurate

    In the past, Ebola diagnostic tests, or assays, have been considered reliable only up to a point. The Ebola virus does not use DNA to store its genetic code. It uses a chemical cousin, called RNA, and extracted RNA degrades easily; one little mistake at the start of a test can ruin the whole thing. Novel process uses a plant virus and may ultimately make Ebola testing more accurate.

  • SuperbugsRise of drug-resistant infections to cost millions of lives, trillions of dollars

    Drug-resistant infections could kill an extra ten million people across the world every year by 2050 if these infections are not tackled. By this date they could also cost the world around $100 trillion in lost output: more than the size of the current world economy, and roughly equivalent to the world losing the output of the U.K. economy every year, for thirty-five years.

  • EbolaStudy finds that Ebola vaccine is safe, stimulating strong immune responses

    A clinical trial of a new Ebola vaccine that resulted from an unprecedented global consortium assembled at the behest of the World Health Organization (WHO) has found that it is well tolerated and stimulates strong immune responses in adults in Mali, West Africa and in the United States. If the vaccine is ultimately found to be safe and effective, it could offer crucial protection for contacts (family members, neighbors, etc.) of patients with confirmed Ebola disease in future epidemics, thereby helping to interrupt transmission. Larger trials of the vaccine sponsored, by GSK Biologicals, have already begun.
