175.(1) If the Health Officer or the medical officer in charge of a hospital or dispensary maintained or aided under section 171 has reason to believe that any person living in the cantonment is suffering from an infectious or contagious disease, he may, by notice in writing, call upon such person to attend for examination at any such hospital or dispensary at such time as may be specified in the notice and not to quit it without the permission of the medical officer in charge; and on the arrival of such person at the hospital or dispensary, the medical officer in charge thereof may examine him for the purpose of satisfying himself whether or not such person is suffering from an infectious or contagious disease: Provided that, if, having regard to the nature of the disease or the condition of the person suffering therefrom, or the general environment and circumstances of such person, the Health Officer or medical officer, as the case may be, considers that the attendance of such person at a hospital or dispensary is likely to prove unnecessary or inexpedient, he shall examine such person at such person's own residence. (2) If any person on examination under sub-section (1), is found to be suffering from an infectious or contagious disease, the Health Officer or medical officer, as the case my be, may cause him to be detained in hospital until he is free from the infection or contagion: Provided that, if having regard to the nature of the disease or the condition of the person suffering therefrom, or the general environment and circumstances of such person, he considers that the detention of such person at a hospital or dispensary is unnecessary or inexpedient, he shall discharge such person and take such measures or give such directions in the matter as he thinks necessary.
