what is stds

STDs, or sexually transmitted diseases, are infections that are transmitted during vaginal, anal, and oral sex. There are more than 20 types of STDs, caused by bacteria, viruses, and parasites. Some common STDs include chlamydia, gonorrhea, genital herpes, HIV, HPV, syphilis, and trichomoniasis. Many people who have STDs dont show any symptoms, so its important to get tested regularly if you are sexually active. Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading STDs. Antibiotics can treat STDs caused by bacteria or parasites, but there is no cure for STDs caused by viruses. However, medicines can often help with the symptoms and lower your risk of spreading the infection. The most reliable way to avoid infection is to not have anal, vaginal, or oral sex. There are vaccines available to prevent some STDs, such as HPV and hepatitis B.
