A large proportion of tuberculosis patients in the US are Asians, most of them Filipinos, a San-Francisco based medical expert has disclosed.

Dr. L. Masae Kawamura, former president of the North American Region of the International Union against Tuberculosis and Lung Disease, told reporters last week about the rising statistics of Filipino patients suffering from TB who are migrating to the United States.

She said Thursday in a press forum that TB is an “outcome of poor public health.” She appealed to the local government and health offices to prioritize early TB screening and bolster treatment in the country.

“The Philippines exports more tuberculosis patients than import at this point… TB is a disease of poverty and migration, and urbanization [because] people are moving from the rural countryside to the big cities like Manila,” said Kawamura.

Ranking second in Asia, the Philippines recorded high TB mortality rate next to Cambodia based on the World Health Organization (WHO) tuberculosis report. Among tuberculosis-afflicted persons, 59 percent came from Asia, the report said.

Kawamura said that tuberculosis can be latent, a condition where the infected does not experience any symptoms.

“To minimize the spread of tuberculosis and an outbreak risk, the government should work on providing a screening for people in congregate settings such as dialysis units, schools, hospitals, jails, prisons, homeless shelters and nursing homes,” she said.

The medical expert claimed that Filipinos living in crowded places, especially those in shanty communities, are more likely to develop and transmit TB.

“Having latent TB even though no one’s at fault carries a lot of stigma especially among Filipinos. The Philippines has a lot of people coming in from other parts of Asia that have high rates of TB as well,” she said.

According to Kawamura, the Philippine government detects only the full-blown TB cases rather than the latent ones.

“It easily evades our immune system and you may carry it as a child but be diagnosed with the disease 50 years later,” she said.

She added that accurate identification of latent TB bacteria is required since these persist in our body for years and decades; they are only inactive.

Kawamura also stressed that contributors could increase an individual’s chance of getting TB.

“Because it affects most of the children, just dealing with malnutrition will help beat tuberculosis. Preventing HIV and diabetes will help reduce TB cases as well. This is how it all interacts,” she said.

The TB control advocate also claimed that “because we breathe, we are all susceptible. Tuberculosis is an equal-opportunity disease. We can all get infected.”

I’m sure most if not all Forum members will know that TB is still a serious disease and testing is a requirement of the visa application process for certain countries, including the Philippines ( since the end of February this year ).


The San Francisco – based medical expert makes valid points, then loses credibility by claiming that " tuberculosis is an equal-opportunity disease. We can all get infected ".


It’s actually a classic disease affecting SUSCEPTIBLE people. We are not all equally at risk. While it’s an extra financial burden and inconvenience for those who need to be tested at the only approved clinic ( in Manila ), I have tried to reassure members that if they are in good general health they are likely to pass their " test " . Overall state of health, poor living conditions, substance and alcohol abuse, and other health conditions such as HIV/AIDS, heighten the risk of active TB.



" Latent " ( hidden ) TB is a difficult concept. It basically means a person has no symptoms and is NOT infectious, but there is evidence of infection ( positive skin / blood tests ). Active TB may ( or may not ) then develop, perhaps years later, and require treatment. Only a specialist clinician can exclude active disease.


Our immune system may react in three ways – it kills the TB bugs ; forms a defensive barrier ( scarring ) round the bugs, known as latent TB ; or fails to kill the bugs which infect lungs and/or other organs. Spread to others is usually because of lung infection with coughing.


Drug-resistant TB is a major worry now. " Multidrug resistance " may affect 4% of new cases and 20% of previously treated cases worldwide. In many countries in Eastern Europe ( especially Romania ) and China, India and the Philippines, these figures are far higher ( up to a third of new patients and at least half of previously treated patients ). There are fewer, but also increasing numbers, of " extensively drug-resistant " TB. Of course EEA nationals don’t need a visa ; they should, but are not obliged to, have pre-entry TB screening . Treating even " normal " TB takes 6 months ; drug resistant types may be 1-2 years; they all require patient " compliance " ( taking the drugs as prescribed ).
