Tourists in New York City avoided Chinatown during the SARS outbreak based on the presumption that Asian Americans frequently travel back and forth to Asia and, therefore, posed a SARS threat. Compounding the problem was that the "public face" of the epidemic—i.e., the images featured in round-the-clock news reports—was that of Asians wearing protective masks. Asian-Americans were branded as "outsiders," a category of person long blamed as the origin of disease.
