Three-quarters of all pediatrics tuberculosis patients in the United States have at least one parent who was born outside the country or has lived outside the U.S., according to a new study published in the journal Pediatrics. The findings suggest that sources of potential TB exposure are not being thoroughly explored by pediatricians, and researchers urge doctors to ask about any potential elevated risk factors.
The study found that among US-born pediatric patients, 66 percent had at least one foreign-born parent, which is more than three times the proportion in the general population. Mexico was the most common country the foreign-born parent was from.
Only 25 percent of pediatric patients with TB diagnosed in the United States had no known international connection through family or residence history.
