Despite their benefits, phone calls in epidemiology come with specific challenges:
1. Privacy Concerns: Ensuring confidentiality during phone calls can be challenging, especially when discussing sensitive health information. 2. Resource Intensive: Conducting large-scale phone surveys or contact tracing requires significant manpower and financial resources. 3. Accessibility: While many have access to telephones, certain populations, such as those in remote areas or with hearing impairments, may not be reachable through this medium.
