HIV in the blood, there is no risk of transmission to others through sexual contact.495) This is a fact that has been proven through numerous studies conducted around the world, and the ‘U=U Campaign’496) is currently underway in the international communities. As of Oct. 2022, 1,099 organizations in 105 countries are participating in the U=U campaign. However, the Korean society still has erroneous knowledge and prejudices about HIV that need correction. According to the ‘2021 Report on the Survey of Knowledge, Attitude, Belief, and Behavioral on AIDS’ among the general public, released by the Korea Centers for Disease Control and Prevention and the Korea AIDS Prevention Association in Nov. 2021, there are a lot of wrong knowledge about AIDS. For example, to the questions, including ‘the probability of sexually transmitted infection is lower than that of other sexually transmitted diseases (AIDS)’ (Answer: O), ‘even an infected person whose HIV is not detected in a blood test can infect a sexual partner’ (Answer: X), ‘ it is unlikely that a person receiving AIDS treatment will transmit AIDS through sexual intercourse’ (Answer: O), less than 15% answered correctly. Only 26.5% of the answers were correct to the question ‘if you are bitten by a mosquito that had bitten a person with AIDS before, you can get infected with AIDS’ (Answer: X). On the other hand, there were also results that could confirm irrational prejudices and rejections in the same survey. In the case of a question about the fact that AIDS is not transmitted through handshakes and hugs, the ratio of correct answer was high at approx. 85%, but about 50% of the respondents answered “yes (somewhat + very much)” to the statement, “I am afraid to shake hands or hug someone with AIDS.” 66.2% of respondents said that they were afraid of eating with a person with AIDS-infected person.497) People living with HIV in Korea experience a very high level of internal stigma.498) According to the 2017 Korean HIV stigma index survey, 75% of the respondents answered 495) Since the possibility of transmission is not 0, the possibility of transmission is sometimes expressed as 'very low' or 'negligible', but this is only a theoretical discussion, and there are no cases of HIV transmission through sexual intercourse between people who are HIV-positive and the virus is undetectable, including a major study of 135,000 cases. Therefore, it seems reasonable to express that there is no possibility of transmission from a medical point of view. 496) Undetectable= Untransmittable. 497) However, it was found that the higher the level of knowledge on all items, the less negative views on the infected person. 498) ‘Internal stigma’ refers to negative evaluations and emotions that people feel about their infection. 205
