Answer:
<em><u>Mode of transmission Method of blocking</u></em>
Indirect Contact -----------→ washing food (A)
Direct Contact -------------→ getting vaccinated (B)
Animal Vector --------------→ using insect repellent (C)
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.
- <em><u>Direct contact</u></em><em>: occurs with direct exposure to a sick person, their breathing or their secretions.
</em>
- <em><u>Indirect contact</u></em><em>: a sick person contaminates an object or food, which is then handled or consumed by another person, acquiring the disease.
</em>
- <em><u>Vector transmission</u></em><em>: Some insects, such as mosquitoes, carry diseases that can be transmitted through their bite to a healthy person.
</em>
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.
