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.

Tolerance and Health: Breakthrough in South Africa?

Monday, May 17th, 2010 by

In previous posts we’ve tracked the links between tolerance, happiness and health and asked whether a wide gender gap may be a barometer of a society’s reluctance to commit to tending to basic human needs. Now recent reports strike a hopeful chord, indicating that tolerance is a precondition for combating the HIV/AIDS epidemic.

First, based on twenty years of data from the U.S., researchers at Emory University are reporting findings of an inverse relationship between tolerance and HIV/AIDS infection rates. In other words, the more open and tolerant a community, the more successful education efforts are. It’s no surprise that HIV/AIDS thrives in the shadows of ignorance, prejudice and fear. If it is true in a society as open as America’s, it’s no doubt doubly true in many other countries of the world. Country-level data on the prevalence of HIV/AIDS and other sexually transmitted diseases is spotty, but experienced travelers know that the highest infection rates are reported in sub-Saharan Africa and Southeast Asia.

So it seemed like a breakthrough last week when the President of South Africa, Jacob Zuma, broke with years of silence and denial to openly discuss his personal history with multiple female partners and his commitment to testing and promoting circumcision to help slow the spread of HIV/AIDS. His openness is a dramatic effort to erase a stigma and set very high standard for tolerance for his people to follow. In office for a year, Mr. Zuma is putting his government’s resources behind what the United Nations has called the largest and fastest increase in AIDS testing and treatment ever.

Perhaps South Africa’s entrance onto the world stage—hosting soccer’s World Cup beginning next month—has helped to enlighten its leadership. If we want tolerance to lay the foundation for a healthier planet, let’s put all world leaders on notice: the whole world is watching.

Uzbekistan and Central Asia: Allure carries risks

Wednesday, March 24th, 2010 by

Tourism has exploded in the Central Asia region.  The exquisite mountains, closed for many years to the West, now attract growing numbers of foreign visitors who are drawn by their natural and unspoiled beauty.  Government officials, hungry for the revenue that tourism generates, are fearful of international scandal.  As a result, there is little transparency when it comes to disclosing failures in infrastructure, including health care systems.

The announcement this week by authorities in Uzbekistan that at least 14 children had died and that another 133 are infected with HIV from contaminated medical equipment is a sober reminder that health care in underdeveloped countries remains perilous. Reports of similar incidents in Kazakhstan and Kyrgyzstan, should make anyone travelling to the former Eastern Soviet bloc wary of the medical treatment they might receive.

Complicating matters further, the government of Uzbekistan is widely believed to have covered up reports in 2007 that HIV contaminated needles and syringes were used to immunize toddlers in the city of Namangan.  Indeed, the details only came to light this week when news broke that 12 doctors and nurses at two hospitals in the city were convicted of using contaminated equipment.  Moreover, Uzbek activist Maxim Popov, who distributed brochures saying condoms and disposable syringes could help prevent HIV, was convicted of corrupting minors by promoting homosexuality, prostitution and drug use. He was sentenced to seven years in jail.

The United Nations says Uzbekistan has one of the world’s fastest-rising HIV infection rates. About 16,000 cases of HIV/AIDS were reported in 2009 — more than an eleven-fold increase from 1,400 cases in 2001, a World Health Organization report said.  Not all of the increase can be attributed to transmission through contaminated needles, however, as the rate of illegal drug use and sexually transmitted diseases has skyrocketed in recent years. 

American tourists must prepare before travelling to Central Asia. As in many underdeveloped regions of the world, most health care remains substandard.  However, risks may be minimized with the proper vetting of medical providers – hospitals and doctors – prior to departure. If you are heading for Tashkent, Almaty or Dusanbe, ask your travel health plan or assistance company for a contingency plan.
