Question

Considering the transmission routes of diphtheria, which combined preventive strategy would be most comprehensive?

Options

• Only face masks without vaccination

• Vaccination, wearing face masks, and maintaining proper sanitation

• Vaccination alone is sufficient

• Sanitation without any other measures

Answer 1

A comprehensive preventive strategy against diphtheria requires vaccination (to provide individual immunity), wearing face masks (to prevent droplet transmission), and maintaining proper sanitation (to prevent contact transmission via contaminated objects). This multi-pronged approach addresses both the biological aspects of immunity and the epidemiological routes of transmission, providing the most effective protection against diphtheria.
