Reading Time: <1 minute"Sexually transmitted diseases Sexually transmitted diseases"It is a disease that is transmitted between the same sex and the opposite sex by physical sexual contact such as kissing and sex. There are also blood-borne and mother-to-child infections. Needlestick injuries of medical workers, viral hepatitis, and mother-to-child transmission from AIDS mothers to their children. Most of these infections are caused by sexual contact, and the number of STIs increases rapidly from the age when sexual activity increases. Sexual contact does not only refer to contact between genitals, but also oral sex and anal sex. In rare cases, STIs can be transmitted by contact with bodily fluids such as secretions from an infected person in a bathhouse. In the past, STIs were called "sexually transmitted diseases," but now that the law has been revised, they are called "sexually transmitted diseases" or "STDs (Sexually Transmitted Diseases)" or "STIs (Sexually Transmitted Infections)." There are more than 20 types, with various incubation periods, characteristics, symptoms, and routes of infection, but not all STIs have subjective symptoms. Some STIs have no subjective symptoms, so some people do not realize they are infected. By the time you find out you are infected, you may have already infected many people, so you cannot be at ease just because you have no symptoms. If you have had sex, you need to be careful. The scary thing about sexually transmitted diseases is that they can spread throughout the body without you even noticing any symptoms, and in women, they can cause infertility, damage the nerves, and even put your life at risk. Not only can it destroy the trust between you and your partner, but it also puts your family at risk of breaking up. If you have the opportunity to be infected, we recommend that you be tested for sexually transmitted diseases regularly. However, sexually transmitted diseases can be false negatives during their respective incubation periods, immediately after infection, or for a certain period of time, so it is important to consider how long it has been since the date of possible infection when deciding on the date of testing. Just because the test result is negative does not mean that you are not infected. In particular, with regard to syphilis and HIV antibodies, even if the test is negative in the early stages of infection, you may actually be infected, so caution is required.https://sakae-clinic.com/body-care/std/
