Surveillance: Monitoring the number of reported cases helps in disease surveillance, which is crucial for early detection of outbreaks and pandemics. Resource Allocation: Health authorities can use the data to allocate resources efficiently, ensuring that areas with high reported cases receive adequate medical supplies, healthcare professionals, and interventions. Policy Formulation: Reported cases provide the evidence base for formulating public health policies and preventive measures. Research: They offer valuable data for epidemiological research, helping scientists understand the transmission dynamics, risk factors, and long-term impacts of diseases.
