Is this jungle parasite killing hundreds of Vietnam vets?

(Chicago Tribune) A half century after serving in Vietnam, hundreds of veterans are learning they may have been infected by a slow-killing parasite while fighting in the jungles of Southeast Asia.

They survived Agent Orange, Two-Step Charlie, and tiger traps. Now a long-dormant jungle parasite is taking them down, one by one.

The Department of Veterans Affairs commissioned a 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 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.

Northport VA Medical Center spokesman Christopher Goodman confirmed the New York facility collected the samples and sent them to the lab. He would not comment on the findings, but said everyone who tested positive was notified.

Gerry Wiggins, who served in Vietnam from 1968 to 1969, has already lost friends to the disease. He was among those who got the call.

“I was in a state of shock,” he said. “I didn’t think it would be me.”

The 69-year-old didn’t have any symptoms when he agreed to take part in the study, but hoped his participation could help save lives.

He immediately scheduled further tests, discovering he had two cysts on his bile duct, which had the potential to develop into the cancer, known as cholangiocarcinoma.

They have since been removed and — for now — he’s doing well.

Endemic in the rivers of Vietnam, the worms can easily be wiped out with a handful of pills early on, but left untreated they can live for decades without making their hosts sick.

Over time, swelling and inflammation of the bile duct can lead to cancer. Read the full story at Chicago Tribune. Also of interest: How Trump Is Fixing Veterans’ Healthcare
