Even Western nations -- where the proliferation of TB detection technology was invented -- are finding it difficult to diagnose the disease.
As Third-world refugees flood into Western nations, the risk of spreading the disease heightens.
According to the Centers for Disease Control:
How is XDR TB spread?
Drug-susceptible TB and XDR TB are spread the same way. TB bacteria are put into the air when a person with TB disease of the lungs or throat coughs, sneezes, shouts, or sings. These bacteria can float in the air for several hours, depending on the environment. Persons who breathe in the air containing these TB bacteria can become infected.
Why is XDR TB so serious?
Because XDR TB is resistant to the most potent TB drugs, the remaining treatment options are less effective, have more side effects, and are more expensive. XDR TB is of special concern for persons with HIV infection or other conditions that can weaken the immune system. These persons are more likely to develop TB disease once they are infected, and they also have a higher risk of death if they develop TB disease.Please report typos...
When a 2-year-old returned sick from a visit to India, U.S. doctors suspected tuberculosis even though standard tests said no. It would take three months to confirm she had an extreme form of the disease — a saga that highlights the desperate need for better ways to fight TB in youngsters in countries that can't afford such creative care.
Drug-resistant tuberculosis is a global health threat, and it's particularly challenging for young children who are harder even to diagnose, much less treat.
Doctors at Johns Hopkins Children's Center are reporting how they successfully treated one of the few tots ever diagnosed in the U.S. with the worst kind — extensively drug-resistant TB, or XDR-TB, that's impervious to a list of medicines.
