VA Study Shows Parasite From Vietnam May Be Killing Vets

A half a century after serving in Vietnam, hundreds of veterans have a new reason to believe they may be dying from a silent bullet — test results show some men may have been infected by a slow-killing parasite while fighting in the jungles of Southeast Asia.

The Department of Veterans Affairs this spring commissioned a small pilot study to look into the link between liver flukes ingested through raw or undercooked fish and a rare bile duct cancer. It can take decades for symptoms to appear. By then, patients are often in tremendous pain, with just a few months to live.

Of the 50 blood samples submitted, more than 20 percent came back positive or bordering positive for liver fluke antibodies, said Sung-Tae Hong, the tropical medicine specialist who carried out the tests at Seoul National University in South Korea.
