On the possibility of local outbreaks of tuberculosis during the endemic period

Abstract

Of the group of children who had been in contact with an unknown source of tuberculosis infection for no more than 6 months, 35.1% were infected and 9.4% of children became ill with intra-thoracic tuberculosis. This situation is interpreted as a local outbreak of the disease during the endemic period of tuberculosis caused by an unknown source of infection in children with reduced specific immunity.
