According to the most recent national tuberculosis (TB) prevalence survey in Myanmar conducted from 2009-2010 and still undergoing analysis, preliminary data show a large proportion of TB cases are going undetected.
In 2010, the World Health Organization (WHO) – working from 2009 estimates not yet confirmed by the latest survey data – estimated 300,000 TB cases out of a total population of 53 million, but that only 64 percent of new cases were being detected.
The latest survey by the government’s national TB program of 51,367 people in 70 geographical areas confirmed the 2009 estimates.
Of the estimated 597 in every 100,000 people nationwide who have TB (316,410 out of 53 million), most are male living in urban areas. The number infected in urban areas is twice as high as in rural areas, as has been the case for years.
“Of the found TB cases in the [2009-2010] national prevalence survey, the majority had not sought health care for TB,” said Eva Nathanson, the TB technical officer in Myanmar’s WHO office.
It may be that patients are ignoring symptoms of their illness, are unaware about TB, live far from health care facilities, are not having their TB detected by health workers, or are being misdiagnosed, she added.
Of those who do start treatment, many abandon it before completion, making them candidates for multi-drug resistant TB, said a government clinic doctor in Mgway Division in central Myanmar who preferred anonymity.
“Many patients do not understand their TB could be resistant if they do not take drugs regularly. It is hard to convince them why they must take their drugs on a regular basis… Some patients stop taking their drugs when their health is getting better. They just come back [to treatment] when their health is bad again.”
