105 Mass. Reg. 300.150
In addition to the diseases and conditions listed in 105 CMR 300.000, the Commissioner, as necessary to reduce morbidity and mortality in the Commonwealth, shall require the reporting, authorize the surveillance and/or establish isolation and quarantine requirements, on a time-limited basis, of confirmed and suspect cases of diseases or conditions which are newly recognized or recently identified or suspected to be a public health concern. Such declarations shall be initially authorized for a period of time not to exceed 12 months, at which point the declaration shall be reviewed to determine whether an extension of time, not to exceed 12 months, is necessary. If such additional time is necessary, the Department shall, during that time, determine whether the requirements should be continued pursuant to a revised regulation under 105 CMR 300.000. Specific requirements of a declaration issued under 105 CMR 300.150 may be updated to reflect changing conditions and understanding of the disease or condition as new data becomes available.
