Answer :
Final answer:
Direct contact involves physical interaction allowing pathogen transmission via body fluids like blood or saliva. Pathogens may require contact with mucous membranes for entry, with examples including mother-to-child transmission and diseases spread through sexual contact or healthcare procedures.
Explanation:
Direct contact involves physical contact between individuals allowing for pathogen transmission through skin or body fluids like blood or saliva. For example, direct contact can occur through kissing, sexual intercourse, or during healthcare procedures.
Many pathogens require contact with mucous membranes to enter the body, potentially leading to infection. Contact transmission may also occur via vertical, horizontal, or droplet transmission, depending on the means of pathogen transfer.
Examples of direct contact transmission include pathogens being passed from mother to child during pregnancy or birth, and diseases transmitted through sexual contact or healthcare procedures involving infected fluids.
