Explanation:
Transmissible infectious diseases are those caused by pathogenic biological agents and can be prevented by preventive measures.
Three forms of contagion are direct contact, indirect contact and vector transmission.
Transmission by direct contact can be prevented or blocked by immunization or vaccination. Properly washing food prevents the spread of disease through indirect contact. The use of insect repellent prevents the vector of a disease from spreading it through its bite.
