Answer 1

Answer:

Infectious diseases are commonly transmitted through direct person-to-person contact. Transmission occurs when an infected person touches or exchanges body fluids with someone else. This can happen before an infected person is aware of the illness. Sexually transmitted diseases (STDs) can be transmitted this way.

Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.

Indirect contact transmission occurs when there is no direct human-to-human contact.

Many STIs are spread through contact with infected body fluids such as blood, vaginal fluids, or semen. They can also be spread through contact with infected skin or mucous membranes, such as sores in the mouth. You may be exposed to infected body fluids and skin through vaginal, anal or oral sex.
