Communicable Diseases Act, B.E. 2558 (2015) · Chapter VI Prevention and Control of Communicable Diseases

Section 34

For the purpose of prevention and control of communicable diseases, when a dangerous communicable disease or an epidemic has occurred or is suspected of having occurred in any area, a communicable disease control officer in such area shall have the power to carry out, or issue a written order instructing any person to carry out the following:

(1) to require persons who are infected or reasonably suspected of being infected with the dangerous communicable disease or epidemic, or who are contacts or carriers to have a check-up or treatment or medical examination and, for the purpose of safety, such persons may be isolated, quarantined or controlled for observation at places specified by the communicable disease control officer until such persons have had a check-up and medical examination and it is confirmed that the period of communicability has passed or such suspicion has been dispelled. In the case of an animal, an owner or occupier of the animal shall take the animal to have a check-up or treatment or medical examination;

(2) to require persons at risk of being infected with the disease to receive immunisation on the date, time and place as prescribed by the communicable disease control officer in order to prevent the transmission of the dangerous communicable disease or epidemic. In the case of an animal, an owner or occupier of the animal shall take the animal to receive the protection against the disease;

(3) to take corpses or carcasses of the persons or animals which are dead or are suspected of being dead of the dangerous communicable disease or epidemic to have an examination or medical management or to be dealt with by any other means in order to prevent the transmission of the disease;

(4) to require owners, occupiers or residents in the houses, tenements, places or conveyances where the dangerous communicable disease or epidemic occurs to conduct a disinfection and destroy anything contaminated, or reasonably suspected of being contaminated with pathogens of the communicable disease or to improve sanitation to ensure hygienic conditions in order to control and prevent the transmission of the disease. The persons receiving the order of instruction shall comply with it until the communicable disease control officer has ordered to cancel the same;

(5) to require owners, occupiers or residents in the houses, tenements, places or conveyances where the dangerous communicable disease or epidemic occurs to prevent the transmission of the disease by eliminating the animals, insects or immature insects which are a cause of the occurrence of the dangerous communicable disease or epidemic;

(6) to prohibit any person from carrying out or performing any act which may cause unhygienic conditions that may result in the transmission of the dangerous communicable disease or epidemic;

(7) to prohibit any person from entering or exiting isolated places, unless permission from the communicable disease control officer has been obtained;

(8) to enter the houses, tenements, places or conveyances where the dangerous communicable disease or epidemic has occurred or is suspected of having occurred for the purpose of surveillance, prevention and control to prevent the transmission of the disease.

In carrying out the actions under paragraph one, the communicable disease control officer shall conduct a disease investigation and if it is found that a dangerous communicable disease or an epidemic has occurred in any area, the communicable disease control officer shall notify the Provincial Communicable Disease Committee or the Bangkok Communicable Disease Committee, as the case may be, and report that information to the Department of Disease Control at prompt.

The criteria, procedures and conditions for carrying out an action or issuing a written order under paragraph one and for conducting a disease investigation under paragraph two, shall be as prescribed in the Notifications by the Minister with the approval of the Committee.
