Deadly superbug outbreak hits problem-plagued network of Ontario hospitals
A deadly outbreak of a highly contagious superbug has claimed the lives of 15 patients in Southern Ontario, raising questions about whether enough is being done to prevent and control the spread of hospital-acquired infections.
Niagara Health System, a sprawling network of seven hospitals serving 434,000 people in a dozen communities, has declared an outbreak of Clostridium difficile, commonly known as C. difficile, at three of its sites.
Farm Animal Disease to Increase With Climate Change, Scientists Say
Researchers looked at changes in the behaviour of bluetongue — a viral disease of cattle and sheep — from the 1960s to the present day, as well as what could happen to the transmission of the virus 40 years into the future. They found, for the first time, that an outbreak of a disease could be explained by changes to the climate.
In Europe, more than 80,000 outbreaks of bluetongue were reported to the World Animal Health Organisation between 1998 and 2010, and millions of animals died as a result of the disease. Bluetongue was previously restricted to Africa and Asia, but its emergence in Europe is thought to be linked to increased temperatures, which allows the insects that carry the virus to spread to new regions and transmit the virus more effectively.
Researchers produced a mathematical model that explains how Read more…
Long Island Officials Warn Of Rapidly Spreading Whooping Cough Virus

SMITHTOWN, N.Y. (CBSNewYork) — A cluster of whooping cough is growing on Long Island, with dozens of people infected by the virus.
As CBS 2’s Hazel Sanchez reports, a warning was sent out as children begin to head to summer camp – a certain breeding ground for the illness.
Parents in Smithtown are on high alert, as the highly contagious whooping cough is spreading through their community.
“It’s one of those diseases you don’t think you’ll ever hear about again,” parent Rick Vollkommer said.
Donna Wilson said she’s not taking any chances with her daughter, Kayla.
“She has been coughing a little bit here and there, so I’m Read more…
Global diabetes cases double to 347 million in less than 30 years, study shows
The number of adults with diabetes in 2008 doubled to 347 million globally since 1980, a study in the journal Lancet says. That is about 10 percent of the world’s adults, and the prevalence of the disease is rising rapidly.
Researchers from Imperial College London and Harvard University in the U.S. looked at data from 2.7 million people worldwide, using statistical techniques to project a global number, according to BBC News. The study found that found that the diabetes rate had either risen or stayed the same in virtually every country.
Although most of the increase was due to population growth and a larger number of elderly people, increased obesity and inactivity, already strong trends in the U.S. and other wealthy western countries, are contributing to the increase in the disease in developing nations including India and countries in Latin America, the Caribbean and the Middle East, according to the Washington Post.
The study, funded by the Bill & Melinda Gates Foundation and the World Health Organization, is a more comprehensive calculation of diabetes prevalence than some previous estimates, according to Read more…
Hong Kong declares scarlet fever outbreak
Hong Kong has declared an outbreak of scarlet fever after it claimed the life of at least one child while infecting thousands of others in the city and elsewhere in China.
A seven-year-old Hong Kong girl died from the illness late last month while a five-year-old boy in the city died Tuesday morning from what health authorities said was a “very likely” a case of scarlet fever.
Hong Kong authorities have recorded 40 new cases in the past few days, pushing the total number to 459 so far this year, the highest annual total in the city and more than three times the figure for the whole of 2010.
The boy — who also had chicken pox — developed a fever last Wednesday and was admitted to hospital on Sunday with symptoms of the illness.
His condition deteriorated rapidly and he died Tuesday morning, Thomas Tsang, controller of Hong Kong’s Centre for Health Protection, said.
Classes have been suspended at the boy’s kindergarten for a week, a first for Hong Kong following a scarlet fever death.
“The situation is rather serious at the moment,” Tsang said Tuesday.
“We are facing an epidemic because the bacteria that is causing scarlet fever is widely circulating in Read more…
A Microscopic Chytrid Fungus Is Causing Massive Declines In Frog Populations Worldwide
A microscopic chytrid fungus is causing massive declines in frog populations all over the world and even the extinction of certain species. Together with colleagues from Europe and the USA, researchers from the University of Zurich present methods as to how the chytrid fungus can be combated in the journal Frontiers in Zoology: namely with bacteria and fungicides. However, the possibility of vaccinating the frogs is also being considered.

New pathogens are not just a growing problem for humans and livestock, but also wild animals. Along with the destruction of their habitats and the overexploitation of their populations, a disease caused by a chytrid fungus called chytridiomycosis is one of the three Read more…
Locusts Invade Russia and China, Threatening Food Supply
Millions of Locusts Invade Russia
June 9, 2011
MSNBC – Giant swarms of locusts are said to be threatening the food supply for nearly 20 million people in the region.
Locust Plague Ravages NW China
May 5, 2011
Xinhua – Large swarms of locusts have laid waste to vast tracts of Northwest China’s Xinjiang Uygur autonomous region, with authorities expecting the plague to worsen as the weather heats up.
The locust plague began in the pastureland of the Ili River Valley and Read more…
Sprouts to Blame for E. Coli Outbreak
Despite no positive findings of Escherichia coli on sampled produce, German officials have determined that bean sprouts are the source of the deadliest outbreak in recent European history.
“It’s possible to narrow it down. It’s the sprouts. However, it’s not yet been possible to detect the pathogen on this product,” said Reinhard Burger, chief of Germany’s national disease control center, during a press conference in Berlin on Friday.
Burger said that the pattern of the outbreak, which has sickened 3,082 and killed 31, has led them to conclude that the source of E. coli is an organic farm in Bienenbuettel, Germany, which is about 70 miles south of Hamburg, the epicenter of the outbreak.
It is possible that no traces of Shiga toxin-producing E. coli (STEC) will ever be linked to the outbreak, as most of the suspected sprouts have been consumed or thrown into the garbage after spoiling, German officials said. However, the hunt for the bacterium is not over.
“Of the 18 samples taken [from the organic farm], eight Read more…
In U.S., Salmonella Is On the Rise While E. Coli Retreats
TUESDAY, June 7 (HealthDay News) — As a deadly new strain of E. coli in Europe makes headlines, U.S. health officials announced Tuesday that salmonella, not E. coli, remains the biggest foodborne health threat to Americans.
In fact, while rates of several types of foodborne illness — including E. coli — have been falling over the past 15 years, there’s been no progress against salmonella infections, according to the U.S. Centers for Disease Control and Prevention.
While infections from Shiga toxin-producing E. coli O157 (the strain of most concern in the United States) have dropped almost in half and the rates of six other foodborne infections have been cut 23 percent, salmonella infections have risen 10 percent, the agency said.
“There are about 50 million people each year who become sick from food in the U.S. That’s about one in six Americans,” CDC director Dr. Thomas R. Frieden said during a noon press conference Tuesday.
In addition, about 128,000 people are Read more…

HONG KONG | Thu Jun 2, 2011 8:13am EDT
HONG KONG (Reuters) – The E. coli epidemic in Europe is caused by a new, highly infectious and toxic strain of bacteria that carries genes giving it resistance to a few classes of antibiotics, Chinese scientists who analyzed the organism said.
The scientists at the Beijing Genomics Institute, who are collaborating with Germany’s University Medical Center Hamburg-Eppendorf, completed sequencing the genome of the bacterium in three days after receiving its DNA samples.
“This E. coli is a new strain of bacteria that is highly infectious and toxic,” said the scientists at the Beijing Genomics Institute in Shenzhen city in southern China.
They said in a press release on Thursday the bacterium was closely related to Read more…
