The United States Centre for Disease Control says the Marshall Islands has the highest rate of tuberculosis among United States-affiliated islands in the Pacific.
With 66 identified cases in 2005, the Marshalls had a rate of 111.7 per 100,000 population.
That is double the rate for U.S.-affiliated islands in the Pacific that average 55.8 cases per 100,000 people.
The Federated States of Micronesia and the Commonwealth of the Northern Mariana Islands have the next highest rate of slightly over 69 cases per 100,000 people.
Palau has 49, Guam has 38 and American Samoa has just over eight.
A total of 275 TB cases have been identified in the six U.S.-affiliated islands
