No person having any form of tuberculosis in a transmissible stage shall be a pupil, teacher, janitor or any other employe in any school except in a special school carried on under the regulations made for such schools by the Secretary of Health. The board of directors of any school district or joint school board may appropriate the necessary funds to pay for X-ray or other medical examinations to determine the presence or absence of tuberculosis in any teacher, janitor or other employe of the district.
