Introduction
In general, the risk of transmitting HIV through casual contact with an HIV carrier—such as sharing meals, shaking hands, hugging, kissing, or using the same toilet or bathroom—is very low. However, the virus can be efficiently transmitted through unprotected sexual intercourse with an HIV carrier or by sharing needles, syringes, or other medical equipment.
HIV, or acquired immunodeficiency syndrome (AIDS), is primarily transmitted through bodily fluids such as blood, semen, vaginal secretions, and breast milk. The transmission efficiency of acquired immunodeficiency syndrome is generally low. If any abnormalities occur, it is recommended to seek medical attention promptly. Specific analysis is as follows:
Under normal circumstances, simply having daily contact with a person carrying the human immunodeficiency virus (HIV), including sharing meals, handshakes, hugs, kisses, or using the same toilet or bathroom, carries a very low probability of transmitting AIDS. Especially given today's advanced medical technologies, such as antiretroviral prophylaxis, the efficiency of viral transmission can be significantly reduced.
However, engaging in unprotected sexual intercourse with an HIV carrier or sharing needles, syringes, or other medical instruments greatly increases the risk of virus transmission. Additionally, if a mother infected with HIV does not receive treatment, there is a high likelihood of transmitting the virus to her infant during pregnancy, childbirth, or breastfeeding.
It is recommended to take preventive measures in daily life. In public settings, extra attention should be paid to maintaining hygiene and cleanliness to reduce the risk of infection.
