Characteristics of a PHE include suddenness and unpredictability [9] . For most hospitals, medicine storage may be in great demand when faced with a sudden increase in patients. Therefore, hospitals must have programs to ensure appropriate levels of emergency supplies including drugs, medical equipment, electricity, water and oxygen, disinfectant, etc. Our survey suggested that most of the hospitals could establish an emergency-drug-supply system for most of the infectious diseases we addressed in the questionnaire except anthrax, brucellosis, botulism toxin poisoning and tetramine poisoning. For most of surveyed hospitals possessed emergency resource reserves, but less than half of them had corresponding drug distribution programs. In addition, hospital capacity was affected by economic level and classification of the hospital, suggesting that the importance of local economic development strengthens hospital ability to provide PHE.
