Events Leading to an Outbreak Report Type A Outbreak

communication between ill persons must be sufficiently frequent that at least a few individuals recognize that there is a problem. Type A outbreaks often involve wedding receptions, socials or holiday parties. These individuals must have enough concern to contact health authorities and be in a position to do so. People rarely report outbreaks arising in their homes. They oftentimes do not know who to contact regarding an outbreak or feel that authorities would not be interested or take any action. Health authorities must have adequate cause and resources to conduct an investigation. Criteria and ability to respond to complaints vary from department to department and may be pre-empted by more emergent situations. Results of the investigation must be sufficient to generate a report. Investigations for which no cause or agent is identified often go unreported.
