• Zika virusObama urges Americans not to panic, asks Congress for emergency funding

    President Barack Obama has urged the American public not to panic about the Zika virus, and has asked Congress for more than $1.8 billion emergency funding to combat further infections. Speaking in an interview on CBS This Morning, Obama said: “The good news is this is not like Ebola, people don’t die of Zika — a lot of people get it and don’t even know that they have it.”

  • Public healthToxic lead can stay in the body for years after exposure

    By Stuart Shalat

    The ongoing water crisis in Flint, Michigan has highlighted just how harmful lead contamination is. What you may not realize, however, is that lead exposure is a problem throughout the United States. The Centers for Disease Control and Prevention estimates that over four million households with children in the United States are exposed to elevated levels of lead. At least half a million children have blood lead levels above five micrograms per deciliter, the threshold that prompts a public health response. Because lead causes irreversible damage, making sure that people are not exposed to lead is especially important. Lead exposure in the United States has been minimized by two government actions – in 1973 and 1977 — but there is still plenty of lead out there. And those who are poor or live in the shadow of abandoned industrial sites are often at greatest risk.

  • Emerging threatsSevere drought no longer caused just by nature

    Scientists are calling on drought researchers and managers around the world to consider both human activity and natural phenomena in their battle to preserve increasingly scarce global water supplies. The experts say that severe droughts experienced recently in countries such as China, Brazil and the United States can no longer be seen as purely natural hazards. Changes to the way people use the water and the landscape contribute to extreme water shortages.

  • Zika virusPlanes arriving from Zika-infected regions to be sprayed with insecticides

    The U.K. government announced that planes landing in the United Kingdom  from areas affected by the Zika virus will be sprayed with insecticide as part of the government’s response to the outbreak. So far there have been no Zika cases reported in the United Kingdom, but two adults in Ireland were confirmed to have been infected. Both have since fully recovered.

  • Zika virusFlorida declares state of emergency in four counties with Zika virus

    Florida Governor Rick Scott has declared a state of emergency in four counties where nine residents have been diagnosed with the Zika virus. Miami-Dade in south Florida, Hillsborough in Tampa Bay, Lee County in southwest Florida, and Santa Rosa County in Florida Panhandle have all been affected under the executive order. Health officials believe, however, that the residents became sick outside the United States.

  • Public healthFBI launches investigation of lead poisoning of Flint’s drinking water

    The FBI has launched an investigation into the contamination of drinking water in Flint, Michigan, which has left Flint children and other residents poisoned by lead. In a hearings on the Hill yesterday, lawmakers from both parties described what is happening in Flint as a “a man-made public health catastrophe.” Flint’s drinking water became contaminated with lead in April 2014 after a state-appointed emergency manager ordered city officials temporarily to switch the city’s water source from Lake Huron water treated by the Detroit Water and Sewerage Department to water from the Flint River, treated at the Flint water treatment plant. The order by the state-appointed emergency manager was part of the state’s cost-cutting measures.

  • Public healthIn kids, even low lead levels can cause lasting harm

    By Robert L. Fischer and Elizabeth Anthony

    Until a few years ago, the federal standard for action was 10 micrograms per deciliter of blood, and in 2012 it was lowered by half in recognition of evidence showing a lower threshold of concern. But the truth is there is no known safe level of blood lead for children, and the American Academy of Pediatrics and the Centers for Disease Control and Prevention have said as much. The medical research community has documented negative impacts on children with even lower levels of lead exposure than the current 5 micrograms per deciliters standard. With that view, we might consider every child with a confirmed nonzero lead test as at-risk. Testing lead blood levels in children is simply too late. This is akin to the TSA searching for lethal weapons after the passengers have boarded the flight and the plan has taken off. Once the lead is in the bloodstream, the damage is real and lasting for these children, and the options for response are far fewer and less effective. Children living in low-income neighborhoods, children of color, and children whose families live in rental housing are statistically at the greatest risk of exposure to lead. That means the children most at risk of lead exposure also disproportionately face the effects of poverty, low-resource communities, and trauma.

    New study finds that the United States, despite having only half the population of the other twenty-two high-income nations combined, accounted for 82 percent of all firearm deaths. In addition, the United State accounted for 90 percent of all women, 91 percent of children aged 0 to 14 years, and 92 percent of youth aged 15 to 24 years who are killed by firearms.

    Criminal charges were filed on Tuesday against Southern California Gas, the utility company whose blown-out natural gas well forced thousands of people in the Los Angeles area to evacuate their homes. The charges claim that the company failed to report the massive leak to the authorities, as it operating license requires.Papers filed in court yesterday claim that the company allowed the release of 80,000 metric tons of methane into the atmosphere.

  • Zika virusWHO calls Zika virus “Public Health Emergency of International Concern”

    The Emergency Committee of the World Health Organization (WHO), after considering the health threat associated with the continuing spread of Zika virus disease in Latin America and the Caribbean, agreed that the situation meets the conditions for a Public Health Emergency of International Concern. WHO called for a coordinated international response to minimize the threat in affected countries and reduce the risk of further international spread.

  • Public healthMost vaccine-related posts on Pinterest are anti-vaccine: Study

    About 75 percent of the vaccine-related posts on Pinterest are negative toward vaccination, according to new research. Messages ranged from simple posts questioning the safety of vaccines to more radical claims that vaccines are being created to kill people. Twenty percent of the posts talked about conspiracy theories, such as pharmaceutical companies out to make money at the expense of children and governments trying to harm children for the purposes of population control. The authors are calling for better communication about vaccination.

    The Blue Ribbon Study Panel on Biodefense responded last week with what it described as “serious concerns” over two emerging infectious diseases that now threaten the United States — Zika virus and avian influenza.

  • E-medicine securityNIST seeks vendors to help secure wireless medical devices

    Medical devices such as the infusion pumps that deliver medication intravenously were once standalone instruments that interacted only with the patient. Today, they have operating systems and communications hardware that allow them to connect to other devices and networks. While this technology has created more powerful tools and the potential for improved patient care, it also creates new safety and security risks.

  • Zika virusMosquito species carrying Zika virus found in Washington, D.C.

    On Monday (25 January), the World Health Organization (WHO) announced that Zika virus, a mosquito-borne illness that in the past year has swept quickly throughout equatorial countries, is expected to spread across the Americas and into the United States. Zika virus is transmitted by the mosquito species Aedes aegypti, also a carrier of dengue fever and chikungunya, two other tropical diseases. Though Aedes aegypti is not native to North America, researchers who study the species have reported a discovery of a population of the mosquitoes in a Capitol Hill neighborhood in Washington, D.C.
