Children with tuberculosis are rarely contagious, but their caregivers may be. Only 7 (12%) of 59 children were potentially contagious, and 10 (17%) were accompanied by contagious adults. Screening caregivers was more cost-effective than performing employee contact investigations, with one-sixteenth the cost ($5,470 vs $88,323) and requiring screening of 35 times fewer persons.
儿童结核病患者很少具有传染性，但他们的照护者可能具有传染性。在 59 名儿童中，仅有 7 名（12%）具有潜在传染性，有 10 名（17%）儿童伴有传染性成人。对照护者进行筛查比进行员工接触者调查更具成本效益，成本为 1/16（5470 美元对 88323 美元），需要筛查的人数也少 35 倍。
