The value 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. Nurses are on the front lines of healthcare. They're in a great position to spot pathogenic diseases and identify communicable diseases quickly. During a disease outbreak, nurses in public and community health clinics usually continue to work as usual. However, they do so in order to prevent disease spread and safeguard their own as well as their patient’s health. Nurses who work in community or public health clinics and have regular and ongoing contact with community members are in a perfect position to spot symptoms of emerging or reemerging infectious diseases.
