Support networks are vital for several reasons: 1. Resource Allocation: They help in the efficient distribution of resources such as vaccines, medications, and educational materials. 2. Information Dissemination: They ensure timely and accurate information reaches the public, which is critical for disease prevention and control. 3. Emotional Support: They provide much-needed emotional and psychological support to affected individuals, reducing the stigma and isolation often associated with diseases. 4. Community Engagement: They engage communities in public health initiatives, making interventions more effective and sustainable.
