Upon being informed by a health officer of any contagious, infectious, or communicable disease the department may take measures as are necessary to ascertain the nature of the disease and prevent its spread. To that end, the department may, if it considers it proper, take possession or control of the body of any living person, or the corpse of any deceased person.
