Plan, analyze, implement, and evaluate public health monitoring and outbreak investigation. 

In order to identify, analyse and address any issues that may arise in public health monitoring or outbreak investigations, a number of steps must be taken. Planning is the first step, which includes identifying factors that may lead to outbreaks and setting goals for handling them.

Next comes analysis, which includes collecting information from different sources like patient questionnaires and surveys. Understanding the specific dynamics in each case is crucial to determining what application would be best under given conditions. After these data have been collected and analyzed the implementation phase begins where all necessary responses or precautions are implemented whatever may happen ultimately leading to a successful outcome. The evaluation phase is the last step, which involves assessing what progress has been made in public health surveillance and outbreak investigations. This will help to determine whether or not there are any further improvements.
