Answer:
Option 3, unprotected sexual contact and direct blood contact
Explanation:
Human immunodeficiency virus (HIV) is a viral infection transmitted through bodily fluids, primarily direct contact with infected blood, semen, and vaginal fluids. Simply touching infected surfaces is not enough to contract HIV, nor is kissing a person living with HIV (unless a HIV-positive person with open mouth sores kisses another uninfected person that happens to have open mouth sores). HIV is not commonly spread through saliva or fomites.
Sexual contact with a person living with HIV without the use of reliable barrier contraceptives is typically the most well understood mode of transmission by the general public. Less commonly referenced, HIV can spread through direct contact with the blood of an infected person. Such can occur with the sharing of intravenous illicit-drug needles or receiving a blood transfusion from a person with HIV-positive status.
For this reason, option 3 is the most common ways of passing HIV, unprotected sexual contact and direction blood contact.
The most common ways of passing HIV are unprotected sexual contact and direct blood contact. Sexual transmission is the primary route, and myths about casual contact spreading HIV are unfounded. Hence the correct answer is unprotected sexual contact and direct blood contact
The most common ways of passing HIV are by unprotected sexual contact and direct blood contact. HIV transmission occurs through direct contact of mucous membranes or the bloodstream with a body fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. Activities like sexual contact or sharing contaminated hypodermic needles are common transmission routes, and mother-to-child transmission can happen during pregnancy, childbirth, or breastfeeding. It is important to debunk myths such as HIV transmission through kissing, sharing glasses, spitting, or touching dirty toilet seats, as these do not allow for the virus to enter the bloodstream or mucous membranes.
