1) to vaccinate or provide precautionary prophylaxis to individuals as protection against communicable disease and to prevent the spread of communicable or possibly communicable disease, provided that any vaccine to be administered must not be such as is reasonably likely to lead to serious harm to the affected individual; and
(2) to treat individuals exposed to or infected with disease, provided that treatment must not be such as is reasonably likely to lead to serious harm to the affected individual.
An individual who is unable or unwilling to submit to vaccination or treatment shall not be required to submit to such procedures but may be isolated or quarantined pursuant to section 96 of chapter 111 if his or her refusal poses a serious danger to public health or results in uncertainty whether he or she has been exposed to or is infected with a disease or condition that poses a serious danger to public health, as determined by the commissioner, or a local public health authority operating within its jurisdiction.

(1) to decontaminate or cause to be decontaminated any individual; provided that decontamination measures must be by the least restrictive means necessary to protect the public health and must be such as are not reasonably likely to lead to serious harm to the affected individual; and
(2) to perform physical examinations, tests, and specimen collection necessary to diagnose a disease or condition and ascertain whether an individual presents a risk to public health.
If an individual is unable or unwilling to submit to decontamination or procedures necessary for diagnosis, the decontamination or diagnosis procedures may proceed only pursuant to an order of the superior court. During the time necessary to obtain such court order, such individual may be isolated or quarantined pursuant to section 96 of chapter 111 if his or her refusal to submit to decontamination or diagnosis procedures poses a serious danger to public health or results in uncertainty whether he or she has been exposed to or is infected with a disease or condition that poses a serious danger to public health.

(d) An officer authorized to serve criminal process may arrest without a warrant any person whom the officer has probable cause to believe has violated an order for isolation or quarantine and shall use reasonable diligence to enforce such order.
(e) Any person who knowingly violates an order for isolation or quarantine shall be punished by imprisonment for not more than 30 days and may be subject to a civil fine of not more than one thousand dollars per day that the violation continues.
