Are children with active TB contagious?
• Children under the age of 12 rarely have contagious TB. This is because they have TB in a different area in the lung and do not aerosolize or cough up their germs into the air. It is for this reason that the Los Angeles County Department of Health Services has been instructed to check the immunization record on these children as being free of communicable TB on the day that the X-ray is taken.
