Neonatal tuberculosis: neonatal intensive care unit considerations in the United States.

According to the World Health Organization, more than 2 billion people, equal to one third of the world's population, are infected with Mycobacterium tuberculosis (TB) bacilli, the microbes that cause TB. In addition, over the past decade, the incidence of postnatal TB in infants has shown an escalating trend in response to the global increase in TB. In providing the best possible care for infants in newborn nurseries and NICU, providers must recognize the trends of TB and multidrug resistant TB in infants globally and consider the possible effects on health care in the United States. The potential risk factors, clinical manifestations, diagnostic strategies, and management plans, specific to the care of infants in the neonatal intensive care unit, is vastly important in maintaining a high index of suspicion for neonatal TB.
