In Japan, limitations on work, recommendation to enter a hospital for infectious diseases and the disinfecting of one’s home is decided by law depending on the type of infectious disease.

Tuberculosis
Though the number of people infected with tuberculosis is fewer than in the past, the disease is the greatest infectious disease in Japan today.
If the discovery of the disease is late, the possibility of infecting one’s family members and others around the infected individual is high.
Receiving tuberculosis health examinations is important. You should receive a tuberculosis health examination at your place of work, school, or at a public health office of the city, ward, town or village where you live.

Venereal disease
Venereal disease does not only affect the infected person but their family and descendents. To prevent the spread of venereal disease, syphilis serum reaction examinations are provided at public health offices and some medical facilities.

AIDS
AIDS (acquired immune deficiency syndrome) is a disease that develops after being infected with HIV. The 3 routes are (1) blood, (2) sexual activity, (3) mother ? child infection.
Privacy will be protected at public health offices. Free consultation on AIDS and anonymous examinations are available here.
Those who think they might be infected are recommended to receive an examination.
