Practice Guidelines and Algorithm: Infant Born to A Mother with A Positive TST
Journal of Pediatric Health Care
Tuberculosis (TB) is caused by Mycobacterium tuberculosis. It is transmitted when a person with active pulmonary TB coughs or sneezes and expels droplet nuclei into the air. Infants infected within the first year of life have a 43% chance of getting the disease. Infants have a very high mortality rate if their condition is not diagnosed and treated early. The presence of congenitally acquired TB in newborns is extremely rare; only 300 cases have been documented worldwide.
