DAVID GREENE, HOST:
The state of Alaska has one of the highest rates of tuberculosis in the U.S., more than twice the national average. Many of the cases pop up in rural areas of the state where treating the disease is especially difficult. Alaska Public Radio Network's Annie Feidt reports on a small team of health care workers who are trying to bring the TB rate down.
ANNIE FEIDT, BYLINE: Three years ago, Dr. Michael Cooper was a family practice doctor, working in Kotzebue, Alaska. The remote arctic community on a narrow sand spit in the Chukchi Sea is home to about 3,000 people, mostly Inupiat Eskimos. At the clinic there, Cooper occasionally saw patients complaining of a persistent cough. They may have also been experiencing night sweats or weight loss. Classic signs of tuberculosis, but...
DR. MICHAEL COOPER: TB was rarely on my list of diagnoses when I would see a patient. I hate to admit that.
FEIDT: Last July, Cooper came to Anchorage for a position with Alaska's Department of Health. The job: lower the state's high rate of tuberculosis.
COOPER: And as I look back now, I go through these patients some nights and I think, that patient could've had TB and why didn't I at least do this? Why wasn't I even aware of it?
FEIDT: So Cooper is learning from his mistakes. He's focusing part of his efforts on educating other doctors and nurses in Alaska about tuberculosis. That starts with explaining why the TB rate is so high in the state. The answer goes back to the beginning of the last century.
COOPER: We experienced probably the highest rates of TB back in the early 20th century found anywhere in the world at the time.
FEIDT: That's because many Alaska natives were living in crowded conditions that allowed TB to spread easily.
COOPER: So if you just imagine a nice cold winter and a packed house full of people and one person having picked up this brand new disease that they have no immunity against and then spreading it - it just can spread like wildfire.
FEIDT: Until 1950, TB was the number one cause of death in Alaska. And that legacy means a large number of Alaskans still carry the bacteria that can cause the disease. They have no symptoms. They aren't contagious. But full-blown TB can flare up at anytime and then spread.
One of the nurses Dr. Cooper works with is Karen Martinek. She's part of a team that responds quickly when a new case pops up.
KAREN MARTINEK: If we see a small, isolated village, you know, usually they are accessible only by air or snow machine in the winter, and we have a case or two of active tuberculosis identified in that village, we can be quite confident that there's transmission going on.
FEIDT: The treatment for active TB is a long course of powerful drugs. For people with inactive TB there's a new, relatively short regimen of drugs that's much less complicated, which eliminates TB. Cooper hopes that will encourage more people with inactive disease to complete the treatment, which would eventually help bring down the high rate of active TB in Alaska. But until then, Dr. Cooper will worry about the potential for epidemics in the state.
COOPER: The impact today is not nearly the scale as it was 50 and 60 and 70 years ago in Alaska, but it's still being felt. And the threat is always there, that this little cluster and this little village, which we rush out and we contain and we get people on drugs and we do the investigation, if that doesn't happen quickly enough, if it doesn't happen thoroughly enough, it still has the potential to turn into a big infection very quickly.
FEIDT: Cooper and others are also worried about strains of TB that are resistant to many of the available drugs. But so far so-called multidrug-resistant TB is not widespread here. And the overall rate of TB in Alaska over the past 20 years has been on a slow decline. Cooper hopes he can keep that trend going.
With a sheepish smile, he says that will involve making sure more doctors in Alaska think about the possibility of TB when each new patient walks through their clinic door.
