The importance of nurses cannot be overstated. Nurses not only offer vital care to patients in need, but they also act as change agents, advocating for patients and supporting health-system improvements. Disease management is a comprehensive method to provide health care services to a person or a group of people who are experiencing the symptoms of a disease. It entails the bringing together and coordinating of numerous systems in order to provide an all-encompassing approach to health-care delivery. During a disease outbreak, nurses in public and community health clinics usually go about their normal business. However, in order to minimise disease, spread and safeguard their own and their patients' health, the way they do so may alter. Nurses in community or public health clinics who have regular and continuous interaction with community members are in a great position to spot new or re-emerging diseases.
