The mode of transmission of a disease is a critical factor in its spread and control. Common modes include:
Direct Contact: Physical contact with an infected person, such as through touching or sexual contact. Indirect Contact: Contact with contaminated surfaces, objects, or vectors like mosquitoes. Airborne Transmission: Spread through respiratory droplets expelled by coughing or sneezing. Waterborne and Foodborne Transmission: Ingestion of contaminated water or food.
