The impact of anthrax attacks on the American public.

CONTEXT: Incidents involving anthrax (Bacillus anthracis) through the mail in 4 metropolitan areas have raised concerns about the public's response nationally and locally.

OBJECTIVE

To examine public response to these incidents and what it reveals about the demand placed on health professionals and public health officials nationally, in affected areas, and by affected people.

DESIGN

Random-digit-dialed telephone surveys of samples of households nationally and in 3 specific metropolitan areas where cases of anthrax were reported: the District of Columbia; Trenton/Princeton, New Jersey; and Boca Raton, Florida.

OUTCOME MEASURE: Respondents were asked a series of questions measuring their level of concern and their behavior in response to threats of anthrax and potential bioterrorist acts.

RESULTS

The lives of a large share of people were affected in 3 metropolitan areas where anthrax incidents occurred. Residents of those 3 areas and people there who were affected by the incidents expressed a higher level of concern and took more precautions handling their mail. However, these incidents did not lead to great demands on the health system.

CONCLUSIONS

The incidents of anthrax created anxieties, especially in areas where incidents occurred. There was some increased demand on the health system, but the demands were not large-scale. In the event of a major outbreak of disease, most Americans will rely heavily on their own physician for advice. Both national and local systems of population-based information gathering about the public's response to bioterrorist attacks are needed.
