Where the local authority within whose district a common lodging-house is situate are not a local health authority, the medical officer of health of the district shall, on the day on which he receives a notice under section 242 of the Public Health Act 1936 (duty of keeper of common lodging-house to notify cases of infectious disease) from the keeper of such a lodging house (if possible) and in any case within forty-eight hours after the receipt of the notice, send a copy thereof to the local health authority within whose area that lodging-house is situate.
In this section " local authority " and " district" have the same meanings as in the said Act of 1936, and " local health authority " means an authority that is a local health authority for the purposes of Part III of the National Health Service Act 1946.
This section does not apply to Scotland.
