Several factors can contribute to Denial of Service in epidemiology: - Resource Limitations: Insufficient staff, medical supplies, and hospital beds can limit the ability to provide care. - High Demand: Sudden surges in patient numbers during outbreaks or emergencies can overwhelm the system. - Logistical Issues: Delays in the supply chain or transportation can hinder the delivery of essential services. - Policy and Planning Failures: Inadequate preparation and poor policy decisions can exacerbate the problem.
