Breathing Easier? New Stricter Air Pollution Standards for Beijing

Thursday, January 12th, 2012 by

In response to international criticism, with much of it coming from the United States, the Chinese government announced on Friday that it would initiate stricter air pollution standards for Beijing by the end of the month.  Residents of Beijing, foreigners and natives alike, have long complained that the Chinese government routinely understates the severity of the problem, with many relying on the United States embassy’s official figures instead. 

Under the more “U.S. like” standards, Beijing officials will begin reporting on the level of tiny floating particles — 2.5 micrometers in diameter or less, known as PM 2.5 — that doctors warn can more easily settle in the lungs and cause respiratory problems and other illnesses.  As we reported earlier, China has only reported on the levels of much larger particles—10 micrometers or more. 

Liu Xianshu, the director of the city’s equivalent of the Environmental Protection Agency, said that they would start reporting the readings of the PM 2.5 at the start of the Chinese New Year, which falls on January 23rd.  This appears to be a reversal from a statement last month made by Environment Minister Zhou Shengxian that the government agency would not begin using stricter standards until 2016. 

HTH Worldwide, sponsor of Healthy Travel Blog, processes dozens of allergy and respiratory related claims from travelers to Beijing, many of whom had no prior history of either type of illness.  Ear, nose and throat specialists in Beijing appear to do a very brisk business removing nasal polyps and expanding sinus cavities of those afflicted with conditions aggravated by heavy pollutants, while pulmonologists are quite busy taking care of asthmatics and those with chronic lung disease who struggle with frequent exacerbations.  HTH consultants in China routinely advise those with severe seasonal allergies and lung conditions to have adequate medications for their trip to Beijing.

Travel Bulletin China: High-speed Train Crash Raises Fears

Thursday, July 28th, 2011 by

A signal failure on the high-speed line between Beijing and Shanghai precipitated a rear end collision that has taken 39 lives and exposed the possibility of deeper, wider problems with the highly touted railway. Critics inside China, including the government itself, cite reckless pursuit of economic growth as a factor in the tragedy. China is the first and only country to have trains hit 220 mph on conventional rail lines. Travelers to China should monitor the government response for signs of increased vigilance to ensure safety along the 6,000 miles of high-speed track.

Travel Bulletin China: Severe Drought Threatens Drinking Water and Power Production

Wednesday, June 1st, 2011 by

The worst drought in fifty years is threatening to severely disrupt life in Hubei, Jiangxi and three other southern Chinese provinces, which traditionally have abundant water resources. Emergency rationing of drinking water is in place for over four million people. At the same time, reduced river flow has hampered hydroelectric power production resulting in rolling blackouts and brownouts. High demand for power during the summer months will likely exacerbate this situation. The drought is also pushing up prices of food, raising the specter of social unrest.

China’s leading environmentalist, Ma Jun, has suggested that China’s poor water management policies are at the root of the problem as much as a lack of rainfall.  The massive Three Gorges Dam is draining downstream lakes, and China is planning to divert huge amounts of water to the arid north via an even larger engineering project over the next four decades.

Road Safety Targeted in Ten Countries Over Five Years

Thursday, January 27th, 2011 by

What’s on track to become a bigger killer than malaria? Vehicular traffic. Unless trends are reversed, cars and trucks will kill 1.9 million people worldwide annually by 2020. To combat this deadly threat, Bloomberg Philanthropies has funded a five-year initiative in Brazil, Cambodia, China, Egypt, India, Kenya, Mexico, Russia, Turkey and Viet Nam where statistics are increasingly grim. A consortium that includes the World Health Organization, Johns Hopkins University and the Association for Safe International Road Travel (ASIRT) is charged with engaging governments and NGOs to promote more responsible driver behavior, trauma care and data collection in each of these countries. Efforts are just getting underway and will continue through 2014. We’ll dig deeper into this topic by  taking a closer look at ASIRT and its activities in one of our next posts.

Buyers Beware: Patients Can Face Sky-high Costs outside the U.S.

Tuesday, January 25th, 2011 by

In sharp contrast to conventional wisdom, there are a number of places outside the U.S. where the cost of medical care can be higher than for the same care at home.  In my role as Medical Director for HTH Worldwide, I see proposed treatment plans and cost estimates that would cause patients without travel health insurance serious financial pain. For example,

  • Surgeon’s fee to remove a thyroid gland in China at $9,000.  The same procedure would cost approximately $1,000 in the U.S., with insurance discounts.
  • Laparoscopic pelvic surgery in South America in the amount of $13,000. Cost is around $7,000 in the U.S. with insurance discounts.
  • Psychotherapy in England may cost as much as $200 per hour.  The average therapist in the U.S. would be happy with half that amount.

In addition, many foreign practitioners generate supplemental income by selling prescription medications directly to patients, and think nothing of recommending more expensive alternatives over older, proven therapies.  Examples include new antibiotics and tumor necrosis factor blocker medications such as Humira and Enbrel.

Unless travelers protect themselves by purchasing travel health insurance, they will be faced with paying the quoted rate or footing the bill for evacuation to the U.S. for tens of thousands of dollars. Most major U.S. insurers provide spotty coverage for healthcare services obtained while visiting foreign lands—and sometimes none at all.  Travel health insurance provides not only coverage, but also a watchful eye to insure that patients receive only effective, evidence-based treatment.

Cholera: Still a big killer, no effective vaccine

Thursday, September 16th, 2010 by

On the quiet London street corner of Broadwick and Lexington stands the John Snow pub with a commemorative plaque honoring the medical detective work of Mr. Snow, who identified the Broad Street water pump as being responsible for an outbreak of cholera that ravaged thousands in 1855.  Today, all patrons of the John Snow can enjoy a pint of local ale, and even more importantly, a refreshing glass of crystal clear, pathogen-free water. It was John Snow who first discovered that cholera, the most feared diarrhea-associated illness in the world, was conveyed by water.

Cholera is caused by the bacteria Vibrio cholera, a powerful pathogen. Untreated cases can lead to dehydration and death within hours of infection.  Cholera is most commonly acquired from drinking water in which the bacteria is found naturally or into which it has been introduced from the feces of an infected person.  The disease can also be acquired from contaminated fish, shellfish or vegetables that have been rinsed with contaminated water.

Cholera outbreaks occur yearly in developing countries.  In 2007, 53 countries reported 177,963 cholera cases and over 4,000 deaths to the World Health Organization Last month, the worst cholera epidemic in almost twenty years broke out in Nigeria.  Nearly 800 people have died, and the epidemic is now spreading to the neighboring countries of Cameroon, Chad and Niger where hundreds of others have succumbed to the illness.

Further east, monsoon flooding that has displaced 18 million people in Pakistan has raised fears of a massive cholera outbreak. Next door, India reports almost seven hundred patients from the state of Orissa have been treated for cholera. Thirty nine patients have been reported dead, and local official N.B. Jawala reports that over 50 new patients are being seen daily with severe symptoms.  ‘We are struggling to prevent the disease from spreading,” he added, “but the patients do not come to the hospital for treatment.”  Indeed, since cholera infection is most often asymptomatic or results in only mild symptoms, the management of a cholera outbreak can be an epidemiologist’s nightmare.  

Travelers who follow tourist itineraries and who observe food safety recommendations are at very low risk. The risk, however, is real for those who drink untreated water or eat poorly cooked or raw seafood in cholera-endemic areas, primarily sub-Saharan Africa, India and China.  Those travelling to developing countries where access to good medical care (intravenous fluid and electrolytes) is limited are at the greatest risk of acquiring and succumbing to the illness. There is no vaccine for cholera available in the United States, and the CDC does not recommend either of the two vaccines available outside the United States because of the low risk of cholera to U.S. travelers and the brief and incomplete immunity that the vaccines confer. Without any medical silver bullets at hand, it appears that this ancient illness is not going away anytime in the near future.

Traveling to India? Be Careful on the Roadways

Wednesday, June 30th, 2010 by

Last summer we analyzed the World Health Organizations (WHO) comprehensive study of road hazards across the world.   The report showed that the differences in fatalities in the analyzed countries were a result of road safety laws and the resources necessary to support them.  Some countries don’t have the road and traffic patterns necessary to manage the large volume of travelers.  The New York Times shows that the road death statistics in India are increasing dramatically while other countries, such as China, are seeing their numbers decline.

Improvements can be made in the form of more strictly enforced safety laws, better roadways, and paths for pedestrians and bikers that will keep them from having to share the already congested roads with careless drivers in unsafe vehicles. 

Before you hit the road this summer, find out what to expect on the roads in your host country.

The World’s Blood Supply — How Safe Is It?

Thursday, June 17th, 2010 by

While most were unaware of it, June 14th was “World Blood Donor Day”, celebrated internationally to encourage those eligible to donate blood at least once a year.  Indeed, although 95% of Americans either receive blood during their lifetime, or know someone who has, only about 8% of Americans currently donate blood.  The requirements are fairly simple: be 16 or older, weigh at least 110 pounds, and enjoy good health.  Apart from doing the right thing, donating blood includes free screening for infectious diseases such as HIV and hepatitis.

The need for “good” blood around the world is critical.  The World Health Organization (WHO) makes a strong statement on blood transfusion safety and places the responsibility for enforcing it on the health administrators around the globe to “galvanize entire communities towards regular and non-remunerated blood donations.”  Just yesterday, one of our clients in China inquired about the reliability of blood in that country.  In fact, some of the blood collected in China may still be contaminated with the HIV virus.  Over the past twenty years, hundreds of cases with dozens of deaths have been traced to blood collected from those in China willing to sell their blood.  Following a government ban on imported blood products in the mid 1980s, literally thousands of blood and plasma collection stations popped up in China offering remuneration for donors. 

These unregulated centers used an unusual method of collecting blood and then reinfusing donors with pooled red blood cells after the plasma had been removed.  The technique was practiced in order to speed recovery following donation but is thought to have infected hundreds of thousands of donors and those who received blood transfusions.  Although Chinese authorities have endeavored to ban this practice and close illegal blood donation stations, the problem has not gone away.  A report published in 2007 claimed that China’s blood supply is still not being properly monitored for HIV.  The demand for blood products is growing, and the supply is short which “creates an economic incentive for hospitals to rely on illegal, untested blood donations.”

China is not alone.  The World Health Organization estimates that 5 – 10% of all HIV infections in Africa occur as a result of unsafe blood transfusions.  In addition, countless thousands are infected with hepatitis and/or malaria due to the lack of proper screening.  The organization “Safe Blood for Africa” is attempting to correct the problem by encouraging voluntary blood donations from adequately screened applicants and discouraging facilities from using untested blood.

The United States, Canada, Japan, France and a host of other developed countries experienced similar problems with contaminated blood from for-profit centers in the late 1970s and early 1980s before adequate screening for HIV and hepatitis was available.  We can only hope that emerging countries learn quickly from the experience of others.  In the meantime, the international traveler must be aware that significant risks still exist from getting blood products in many parts of the world.

New Japanese Encephalitis Vaccine Reduces Side Effects

Wednesday, May 19th, 2010 by

Good news for travelers throughout Asia.  There is a new vaccine against Japanese encephalitis that significantly reduces typical side effects.

We all know that mosquitoes transmit some very serious viruses to humans. In addition to malaria and dengue fever, another mosquito-driven disease is Japanese encephalitis virus (JEV).  As reported by the World Health Organization (WHO) JEV is endemic in parts of China, India, the Republic of Korea, Japan, the Russian Federation, islands in the Torres Strait of Australia, Nepal, Thailand, Viet Nam, Cambodia, the Lao People’s Democratic Republic, the Philippines, Taiwan, Indonesia, Malaysia, and Sri Lanka. Its breakouts are generally most prevalent during the summer and fall.

There is no treatment available for this disease which can lead to permanent damage to the nervous system or death. Though many vacationers or expats will not find themselves in high-risk areas during peak times, it is recommended by the Centers for Disease Control (CDC) that anyone travelling to an endemic area during a possible transmission season or those who are headed toward a potentially dangerous area should be vaccinated for JEV.

Historically, the vaccine was toxic to some people — especially those with a history of allergy to wasp/bee stings.  Many doctors were hesitant to give the traditional vaccine and if they did, they would advise recipients to stay in a country with decent medical facilities in case they were one of the rare cases to develop an allergic reaction within 10 days of receiving the vaccine.  Fortunately for those over 18 years of age, there is now a new vaccine that does not cause those side-effects and can be given as safely as any of our other vaccines.

In summary: If you are over 18 years old and travelling to one of the high risk areas mentioned above, ask your doctor for the new non-allergic Japanese encephalitis vaccine.
