Norovirus: Dozens of staff and patients sickened at Phoenix VA
At least 35 people, including 16 patients and 19 staff members at The Carl T. Hayden Veterans Affairs Medical Center have contracted norovirus. According to a hospital press release, everyone infected was from two inpatient mental health units and to date, all but three have fully recovered.
The Phoenix VA hospital stopped taking new patients at two mental health units with 48 beds on the hospital’s fifth floor. VA officials have embarked on a cleaning regimen to rid the hospital of the highly-contagious virus. Some steps included limiting staff members who are allowed to access the affected floors and using paper trays to deliver food, according to Phoenix VA Health Care spokeswoman Jean M. Schaefer.
Norovirus is a highly contagious viral illness that often goes by other names, such as viral gastroenteritis, stomach flu, and food poisoning.
From Al Jazeera America, deadly outbreaks from an instrument of healing:
Medical scope now tied to Wisconsin superbug outbreak
- Congressman considers bill to force states to notify federal agencies of superbug outbreaks and medical device failures
A medical device called a duodenoscope that’s been linked to recent deadly superbug infections across the country was also connected to a 2013 outbreak at a Wisconsin medical facility that infected five people, America Tonight has learned.
Health officials at the Wisconsin Department of Health Services confirmed the five patients were sickened with NDM1 – a subgroup of an antibiotic-resistant “superbug” known as carbapenem-resistant Enterobacteriaceae, or CRE, that’s responsible for two deaths at UCLA’s Ronald Reagan Medical Center in Los Angeles since October and dozens of serious infections around the country in recent years.
Meanwhile, Cedars-Sinai Medical Center, another Los Angeles hospital, announced Wednesday that four patients there were infected with the deadly superbug due to a dirty duodenoscope and that 64 more patients may have been exposed since August.
From the European Centre for Disease Prevention and Control [PDF], measles numbers on another continent:
A large measles outbreak is ongoing in Berlin. As of 24 February 2015, media report nearly 600 cases. The outbreak that started in October 2014 initially affected asylum seekers from Bosnia and Herzegovina and Serbia but has now spread to the general population. According to media, at least two cases in Berlin have been linked to the United States. One involved a woman who developed symptoms in the United States before travelling to Berlin. A second involved a child who developed the infection after returning from the United States of America. There has been one death in an 18 months old unvaccinated toddler. The child fell ill in the Reinickendorf district of Berlin on 12 February with fever and cough and later rash. The child was hospitalised due to worsening condition on 14 February and died in hospital on 18 February. The child was not vaccinated against measles and had no pre-existing conditions.
Media report two epidemiologically linked cases of measles in children in Copenhagen.
Since November 2014 and as of 13 February 2015, 228 cases of measles have been reported in Serbia in several outbreaks affecting numerous areas of the country. This is an increase of 105 cases since 26 January 2015, the last monthly update.
Kyrgyzstan – update
According to WHO, Kyrgyzstan has reported 7477 cases between May 2014 and February 2015. The first case was identified in Bishkek city on 3 May 2014, but the number increased dramatically in 2015.
From BBC News, causation:
Autism is largely down to genes, twin study suggests
Autism is caused by genetic make-up in 74-98% of cases, a Medical Research Council study of 516 twins indicates.
The King’s College London team said 181 of the teenagers had autism, but the rate was far higher in the identical twins, who share the same DNA. The researchers told JAMA Psychiatry tens if not hundreds of genes were involved, and they do not rule out environmental factors entirely.
Both twins in each pair had been raised by their parents in the same household.
The World Health Organization issues a call:
WHO calls on countries to reduce sugars intake among adults and children
A new WHO guideline recommends adults and children reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (6 teaspoons) per day would provide additional health benefits.
Free sugars refer to monosaccharides (such as glucose, fructose) and disaccharides (such as sucrose or table sugar) added to foods and drinks by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
“We have solid evidence that keeping intake of free sugars to less than 10% of total energy intake reduces the risk of overweight, obesity and tooth decay,” says Dr Francesco Branca, Director of WHO’s Department of Nutrition for Health and Development. “Making policy changes to support this will be key if countries are to live up to their commitments to reduce the burden of noncommunicable diseases.”
The WHO guideline does not refer to the sugars in fresh fruits and vegetables, and sugars naturally present in milk, because there is no reported evidence of adverse effects of consuming these sugars.
Much of the sugars consumed today are “hidden” in processed foods that are not usually seen as sweets. For example, 1 tablespoon of ketchup contains around 4 grams (around 1 teaspoon) of free sugars. A single can of sugar-sweetened soda contains up to 40 grams (around 10 teaspoons) of free sugars.

McDonald’s to phase out serving chicken raised with antibiotics
McDonald’s Corp. will phase out over the next two years the use of chickens raised with antibiotics important to human health in a step to combat resistance to antibiotics.
The Oak Brook, Ill. fast food giant said Wednesday that later this year it will also begin selling only milk from cows that are not treated with the artificial growth hormone rbST.
Farmers in the company’s supply chain can continue to use ionophores, a type of antibiotic not used for humans, on their chickens.
From the Guardian, Aussie bananas threatened:
Queensland banana farm quarantined after testing positive for fungal disease
- Biosecurity experts warn Panama TR4 disease could pose a serious threat to the banana industry in Australia
A north Queensland banana farm has been quarantined after testing positive for a potentially destructive fungal disease.
Biosecurity Queensland has warned that the Panama TR4 disease would have serious consequences for the state’s banana industry if it spread from the plantation near Tully, south of Cairns.
Panama, a soil fungus, was found in the Northern Territory in 1997 and has since spread to a number of areas in the Top End, but this is the first time it has been detected at a Queensland plantation.
Science covers sewer diagnostics:
Pollution, human health tracked with sewage microbes
Microbiologists have a new way to tell whose sh-t is dirtying the waters. A survey of sewage across the United States shows that every city has a distinct microbial character that can reveal signs of health, such as how obese its residents tend to be. Dozens of the microbes identified in the survey are common throughout the United States, and could provide better ways to tell whether bacterial pollution comes from humans.
The human gut is filled with microbes that are proving ever more important to health and disease. To understand the diversity of these bacteria—collectively called the gut microbiome—and how their numbers and types vary through time, microbiologists have isolated and sequenced DNA from stool samples of hundreds of individuals. But Mitchell Sogin, a molecular evolutionist at the Marine Biological Laboratory in Woods Hole, Massachusetts, and Sandra McLellan, a microbiologist at the University of Wisconsin, Milwaukee, wanted to take a much broader view and study the microbiomes of entire human communities. In addition, they were looking for a better indicator of human fecal pollution.
To do that, they needed to figure out how to assess the microbiomes of large numbers of people at once. They recruited wastewater treatment plant operators from 71 U.S. cites to collect more than 200 samples of incoming sewage. They then sequenced DNA in the samples and determined its origin. About 15% of the isolated sewage DNA belonged to microbes found in humans, Sogin and McLellan’s team reported online last week in mBio. Many of the rest are microbes that live in sewer pipes. Using a technique developed by Sogin and his colleagues, which can more precisely determine which bacteria are present in a large sample of feces, the researchers identified about 60 types of bacteria that were common to people in all of the cities. Because they seem to be found wherever humans are, these 60 may be a more reliable way to determine if human feces are contaminating a waterway, McLellan says.
From StarAfrica, African climate change costs:
Africa’s climate adaptation costs to hit $50 billion -UNEP
Africa, the continent with warming deviating most rapidly from “normal” conditions, could see climate change adaptation costs rise to $50 billion per year by 2050, even assuming international efforts keep global warming below 2°C this century, according to a new United Nations Environment Programme (UNEP) report.
Released on Wednesday at the 15th African Ministerial Conference on the Environment (AMCEN), Africa’s Adaptation Gap builds on UNEP’s Emissions Gap Report 2014, which showed that the world is not currently headed in the right direction for holding global warming below 2°C.
This latest Africa Adaptation Gap report also builds on UNEP’s Global Adaptation Gap Report 2014, which found that adaptation costs in all developing countries together could climb as high as $250-500 billion per year by 2050.
Produced in collaboration with Climate Analytics and the African Climate Finance Hub, the report says deep global emissions reductions are the best way to head off Africa’s crippling adaptation costs.
