E. coli Detective Work Produces No Answers

Tuesday, June 7th, 2011 by

Although it has been over a month since the first case of enterohemorrhagic E. coli was reported in Germany, officials in that country have yet to identify the source of the outbreak.  Although both Spanish cucumbers and sprouts grown by German farmers have been implicated, further tests have failed to substantiate initial claims.  The inability to positively identify the source of the bacteria is rapidly becoming a source of embarrassment for the country.

German officials acknowledge that time is not on their side, as the number of new cases appears to be on the decline, and testing produce several weeks after the initial outbreak may no longer be helpful.  Dr. Guenael Rodier, an epidemiologist at the World Health Organization, told the Associated Press on Tuesday that the contaminated vegetables have likely disappeared from the market and it will be difficult to link patients to produce so long after they first became infected. He added, “If we don’t know the likely culprit in a week’s time, we may never know the cause.”

Despite the fact that the source remains elusive, there is little question that vegetables are the culprit and that washing and peeling all fruits and vegetables is the only sure way to prevent food-borne illness.

E. coli: Search for the Source Continues

Monday, June 6th, 2011 by

Scientists continue to work to identify the source of the new deadly strain of E. coli bacteria that has infected over 2,200 people in 12 European countries. “This is a unique strain that has never been isolated from patients before,” Hilde Kruse, a food safety expert at WHO, told The Associated Press.  The new strain has “various characteristics that make it more virulent and toxin-producing” than the many E. coli strains people naturally carry in their intestines.

Despite speculation over the weekend that the outbreak could be traced to a German bean sprout farm, the search for the source continues.  German authorities on Sunday issued a warning against eating any sprouts and repeated earlier warnings against eating tomatoes, cucumbers and lettuce.  The WHO is recommending the usual precautions to avoid illnesses that are transmitted by raw food — wash hands before eating or cooking and wash and peel all fruits and vegetables, especially if eaten raw.

HTB will continue to monitor what is turning out to be the worst outbreak of E. coli-related illness in eleven years, and already the third-largest involving E. coli in recent world history.

Rare Bacterial Infection Hits Europe

Wednesday, June 1st, 2011 by

An unusually toxic version of the “Montezuma’s revenge” bacteria known as enterohemorrhagic E. coli, or EHEC,  is sweeping Europe this week and is now thought to be responsible for at least 17 deaths and over 1,500 cases of severe illness known as “hemolytic uremic syndrome.”  The World Health Organization (WHO) said cases of the E. coli illness have been reported in nine European countries: Austria, Denmark, Germany, the Netherlands, Norway, Spain, Sweden, Switzerland and the U.K. All but two cases are either people in Germany, or people who had recently traveled to northern Germany, the organization said.  The source of the food borne bacteria, generally found on vegetables, has thus far evaded health officials. Scientists are working hard to find the source of the contaminated vegetables.

Benign strains of the E. coli inhabit the human intestinal tract, while other strains are responsible for much of the diarrhea experienced by travelers to underdeveloped countries with poor water sanitation.  But EHEC, causes more severe symptoms, ranging from bloody diarrhea to the rare hemolytic uremic syndrome (HUS), in which E. coli infection attacks the kidneys, sometimes causing seizures, strokes, comas and death.

“The idea of an outbreak of over 300 hemolytic uremic syndrome cases is absolutely extraordinary,” said Dr. Robert Tauxe, deputy director of foodborne, waterborne and environmental diseases at the U.S. Centers for Disease Control.  “There has not been such an outbreak before that we know of in the history of public health,” Tauxe said, adding that the German strain of E. coli has not been seen in the United States.

Anyone traveling to Europe should be aware of the situation and avoid the consumption of raw vegetables until the situation is resolved.

If you want to track the situation, The Guardian has created an interactive map to track the E. coli spread across Europe.

WHO Reports Cell Phone Use May Cause Cancer

Wednesday, June 1st, 2011 by

In yesterday’s press release on radiofrequency electromagnetic fields, the World Health Organization’s International Agency for Research on Cancer (IARC) announced it has classified the exposure to radiation from cell phones and other similar radiation-emitting devices (radar, microwaves, radio, television) as a Group 2B carcinogenic risk.  To put that into perspective, the IARC has five classifications:

  • Group 1 – carcinogenic to humans
  • Group 2A – probably carcinogenic to humans
  • Group 2B – possibly carcinogenic to humans
  • Group 3 – not classifiable as to its carcinogenicity to humans
  • Group 4 – probably not carcinogenic to humans

There are several hundred items classified as Group 2B, ranging from talc-based body powder to surgical implants made from nickel to titanium dioxide (used in paint, sunscreens and food coloring). Coffee is also a 2B item even though recent studies show that coffee drinking lowers the rate of prostate cancer.

While this news may be scary, I still believe in the old adage of “moderation in everything” — try to limit your cell phone use and use a headset if possible, but don’t let this news make you go back to smoke signals and the telegraph.

Travel Bulletin Syria: Regime Kills Hundreds

Monday, April 25th, 2011 by

Human rights groups say the Assad regime has killed more than 350 civilians since unrest began, and more than 100 over the last three days. Security forces using tanks have launched pre-emptive strikes against the most restive cities, among them Daraa, Nassib, Jablah and the Damascus suburb of Douma in what protest leaders call “a war to annihiliate the pro-democracy movement.” Today’s raids appear to show the regime’s determination to crush dissent.  Reports are reaching the outside world via the Internet as Syria has banned all foreign media coverage of the clashes.

A World Working to Diminish Measles, Malaria and Other Preventable Diseases

Saturday, April 23rd, 2011 by

Earlier this week the World Health Organization (WHO) reported that 6,500 measles cases have been reported in Europe.  As noted in our earlier post, France is reporting much higher numbers than other countries, but Spain and the former Yugoslav Republic of Macedonia are in a distant second and third.

As with so many infectious diseases, there is a vaccine available to minimize the risk of contracting or spreading the infection.  This is one of the many reasons that 180 countries will be recognizing World Immunization Week starting on April 23rd under the auspices of the World Health Organization. Some of the WHO regions will be focusing on general messaging, such as Europe’s focus on “shared solutions to common threats”, while some will be more specific — Africa will focus on vaccinating for polio.  

Another commemorative day on the global health calendar is World Malaria Day, Monday, April 25th. The event serves as an opportunity for the Roll Back Malaria (RMB) Partnership to check progress and renew efforts towards their aggressive goal to eliminate malarial deaths by 2015.

Do you follow or support any of these (or other) disease elimination campaigns? We’d like to hear about them.

Earth Day: A Truly Healthy International Event

Friday, April 22nd, 2011 by

At its founding in the U.S. in 1970 as the National Environmental Teach-In, Earth Day inspired an estimated 20 million participants, most of them students and teachers, to address local environmental issues. Springing from college campuses, environmental awareness marched steadily around the globe so that in 1990 the first International Earth Day was celebrated by 200 million people in 141 countries.  Today the United Nations and 175 countries recognize April 22nd as International Mother Earth Day. It’s estimated that anywhere from 500 million to a billion people will celebrate Earth Day this year by learning about opportunities to improve their local environment. Given the magnitude of environmental stress the planet is already facing, it’s encouraging to know that Mother Earth—Pachamama if you are in Bolivia–has so many people on her side.

Arab Unrest: Doctors, Nurses Arrested for Treating Protesters

Friday, April 15th, 2011 by

A recent report in the New York Times, based in part on research by Human Rights Watch, paints an alarming picture in Bahrain.  Security forces are invading hospitals and clinics or stopping ambulances to find wounded protesters and then taking their care-givers into custody.

Presuming sympathy with the protests, the Bahraini government has announced that 30 doctors and nurses had been suspended from practicing and that 150 more are being investigated. Outside observers say at least a dozen doctors and nurses have been arrested and held prisoner during the last month. Human Rights Watch has characterized these developments as “an assault on the health care system.”

Designed to instill fear, this crackdown is apparently having the additional effect of depriving people, protesters or not, of the care they need. This scenario is likely playing out in other cities rocked by Arab protests, particularly in Libya. Clearly, travelers witnessing Arab unrest should add a shortage of doctors and nurses to the list of risks they face.

UK Epidemiologists Disclose Spread of Superbug: WHO Rings Alarm

Friday, April 8th, 2011 by

New research published this week in the prestigious medical journal The Lancet has disclosed the presence of super bacterium NDM-1 in the drinking and ground water in Delhi, India. NDM-1 resists treatment by the most powerful antibiotics available and could spark a worldwide spread of untreatable infections. NDM-1 has already been carried from India to Europe by “medical tourists” who contracted the infection during a hospital stay.

Upon learning this news, the World Health Organization (WHO) sounded an alarm asking medical researchers around the globe to take up an urgent collective effort to combat NDM-1. The WHO is particularly concerned because

  • The population density of India suggests that millions of people may already be carriers
  • The NDM-1 gene has spread to bacteria that cause dysentery and cholera, which are easily passed among humans who drink sewage-contaminated water
  • 650 million people in India do not have access to toilets served by sewers

WHO Regional Director Zsuzsanna Jakab said “Given the growth of travel and trade in Europe and across the world, people should be aware that until all countries tackle this, no country alone can be safe.”
