• Ebola discussion in U.S. driven by fear, not science: Infectious disease experts

    A significant part of the Ebola debate in the United States has been driven by fear, not science, according to infectious disease experts. Despite assurances from public health officials, the general public continues to be fearful of an Ebola outbreak in the United States. Some states have imposed mandatory quarantines for all healthcare workers returning from Ebola-stricken West Africa, even if they show no symptoms.”The fear is trumping science,” said Dr. Georges Benjamin, executive director of the American Public Health Association.

  • Use of Ebola virus as bioterror weapon highly unlikely: Experts

    Francisco Martinez, Spain’s state secretary for security, claimed that ISIS fighters are planning to carry out “lone wolf” attacks using biological weapons. He cites conversations uncovered from secret chat rooms used by would-be militants. Bioterrorism experts say the use of Ebola for bioterrorism is highly unlikely. “Assuming a terrorist organization manages to capture a suitable Ebola host, extract the virus, weaponize the virus, transport the virus to a populated city and deliver the virus, it is entirely likely that the sub-optimal climatic conditions of a Western city will kill it off relatively quickly,” says one expert.

  • Fast-spreading killers: how Ebola compares with other diseases

    The West African outbreak of Ebola has claimed more than 4,800 lives and this number is sure to rise. There is understandably a lot of fear about Ebola, but how does it actually comp re with other fast-spreading infectious diseases? While bubonic plague is bacterial, all of the other infections mentioned below – influenza, Bird Flu, SARS, Ebola, and HIV/AIDS — are viral. Yellow fever was the first human virus to be discovered in 1901. Since then more than 200 have been recognized. Ebola has all the epidemiological characteristics of a containable infection, but it is only now spreading to developed countries that have no experience of dealing with it. The desirable strategy, from global health and humanitarian perspectives, is to eliminate the epidemic at its source.

  • Funding cuts hamper health agencies’ ability to prepare for, respond to Ebola

    Federal and state funds for local health agencies have been cut over the past few years, so when hospitals and municipal health agencies are asked proactively to respond to possible threats of Ebola, many question how they will fund such activities. Since 2008, at least 51,000 state and local public health jobs (roughly 20 percent) have been lost due to cuts in federal funding.

  • Epidemics do not require long-distance travel by virus carriers to spread

    The current Ebola outbreak shows how quickly diseases can spread with global jet travel. Yet knowing how to predict the spread of these epidemics is still uncertain, because the complicated models used are not fully understood. Using a very simple model of disease spread, UC Berkeley biophysicist Oskar Hallatschek proved that one common assumption is actually wrong. Most models have taken for granted that if disease vectors, such as humans, have any chance of “jumping” outside the initial outbreak area — by plane or train, for example – the outbreak quickly metastasizes into an epidemic. Hallatschek and colleagues found instead that if the chance of long-distance dispersal is low enough, the disease spreads quite slowly, like a wave rippling out from the initial outbreak. This type of spread was common centuries ago when humans rarely traveled. The Black Death spread through fourteenth-century Europe as a wave, for example.

  • U.S. will see between 1 and 130 additional Ebola cases by end of 2014: Experts

    Top U.S. medical experts studying the spread of Ebola predict a few more cases will reach America before year’s end, citing the return of healthcare workers currently working in West Africa as the most likely cause of new cases. Using data models that weigh several variables including daily new infections in West Africa, global airline traffic, and transmission possibilities, top infectious disease experts predict as few as one or two additional infections and as many as 130 by the end of 2014.

  • Rate of infection in West Africa has begun to slow down

    Public health officials monitoring the Ebola epidemic in West Africa say the outbreak may have reached a turning point in which transmissions may have begun to slow down. Dr. Jeremy Farrar, director of the Wellcome Trust, the organization funding a series of fast-tracked trials of Ebola vaccines and drugs, says that although the virus will continue to infect people in the months ahead, “it is finally becoming possible to see some light.”

  • Infection outbreaks, unique diseases on the increase since 1980

    Ebola has a lot of company. In a novel database now made publicly available, researchers found that since 1980 the world has seen an increasing number of infectious disease outbreaks from an increasing number of sources. The good news, however, is that they are affecting a shrinking proportion of the world population. The number of infectious disease outbreaks and the number of unique illnesses causing them appear to be increasing around the globe, with more than 12,000 outbreaks affecting forty-four million people worldwide over the last thirty-three years.

  • Lack of federal authority makes fashioning coherent national Ebola policy difficult

    Earlier this week, the Centers for Disease Control and Prevention(CDC) issued new guidelines on how states should deal with travelers from Ebola-stricken regions, but a lack of federal authority to mandate such guidelines has led to conflicting strategies, varying from state to state, which includes mandatory at-home quarantine for some travelers. Under current U.S. law, the states have the authority to issue quarantine or isolation policies, and they also control the enforcement of these policies within their territories.

  • Legality of mandatory quarantine of asymptomatic individuals questioned

    Roughly three decades ago, patients in New York were forced into isolationafter an outbreak of tuberculosis, and about seventy years before that, an influenza pandemic led to mass quarantine in major American cities. Today, fear of an Ebola outbreak in the United States has led some states to mandate quarantine of individuals suspected of having the Ebola virus, but legal analysts question the legality of such measures.

  • Experts consider implications of Ebola strain being stolen from lab

    As the Ebola virus continues to plague several Americans and Europeans and thousands in Africa, researchers are beginning to examine the outcomes should a strain of Ebola be stolen from a testing laboratory. Many scientists in U.S. labs study the Ebola virus in order to find out how they can fight it. They wonder, however, what set of procedures are in place if a sample of the virus was stolen.

  • Insurance companies now write Ebola exclusions into policies; offer Ebola-related products

    U.S. and British insurance companies have begun to write Ebola exclusions into their policies for hospitals, event organizers, airliners, and other businesses vulnerable to disruption from the disease. As a result, new policies and renewals will become more expensive for firms looking to insure business travel to West Africa or to cover the risk of losses from Ebola-driven business interruptions (BI).The cost of insuring an event against Ebola, for example, would likely be triple the amount of normal cancellation insurance — if the venue was in a region not known to be affected by the virus.

  • Private cleaning firms had to improvise when cleaning apartments of U.S. Ebola patients

    Officials responsible for disinfecting the Ebola-infected homes of Thomas Eric Duncan’s fiancee, and of the two nurses he infected, relied on best decontamination practices, but note that an official manual for responding to a home contaminated with the Ebola virus was nonexistent at the time. OSHA recently announced official guidelines for “Cleaning and Decontamination of Ebola on Surfaces” for workers and employers in non-healthcare/non-laboratory settings.

  • First New York Ebola case confirmed

    Dr. Craig Spencer, who had been working with Doctors without Borders in Guinea and treating Ebola patients before returning to New York City on 14 October, was taken to Bellevue Hospital yesterday (Thursday) and placed in strict isolation. Tests later determined that he had contracted the Ebola virus. Spencer is the first New Yorker diagnosed with Ebola. As if in anticipation of a case like Dr. Spencer’s, more than 5,000 healthcare workers in New York participated in a three-hour session earlier this week to prepare for Ebola should an infected person arrive in the New York City region.

  • RMS develops probabilistic model of West African Ebola outbreak

    Current outbreak has the potential to be the deadliest infectious disease event since the 1918 flu pandemic. The outbreak will worsen and could reach as many as 1,400 new cases per day within a month, according to pandemic risk experts. According to a new model developed by RMS, until a tipping point is reached at which the number of new daily cases declines rather than increases, the severity of the outbreak will continue to multiply, with the total number of new cases approximately doubling each month.
