A fundamental role of public health agencies is the collection and analysis of data that facilitate the identification, control, and further prevention of the spread of infectious diseases. All states require the reporting of certain diseases to either the local or state health department. Physicians are required to report all notifiable diseases. In some states laboratories, hospitals, and others are also required to report. The method and timing of the report may range from a weekly card via mail to an immediate phone call. The data from the states are then forwarded to the Centers for Disease Control and Prevention. There are a few disease conditions that are then reported to the World Health Organization.
