The experience of this county medical society shows that a public health committee can be extremely effective in dealing with many local community needs. The parent committee has been in a position to call on members of the society to help communicate the message of health to people in public meetings, radio broadcasts, newspapers, and programs arranged by nonmedical groups. A plan for periodic health examinations for physicians themselves has been carried out, important legislation has been obtained, a directory of medical and social services is in preparation, and many special health problems have been investigated. Subcommittees have been successful in encouraging immunization against poliomyelitis and in organizing campaigns for mental health. The results of these sometimes laborious efforts have amply justified the expenditure of time and energy.
