Syphilis. Syphilis is a bacterial infection that can be easily missed. The first symptom is a painless blister or sore that will disappear on its own, but the infection can be passed on to others for up to eighteen months. Syphilis can be treated with antibiotics. However, if left untreated, the disease can spread throughout your body over the course of many years and cause considerable organ damage.
Chlamydia. Chlamydia trachomatis is often called "the silent epidemic" because infections are common yet many people do not realize that they are infected. Only one in four of infected people have symptoms of a slight discharge and stinging on passing urine. It is the commonest STD in the UK. This bacterial disease is easily cured with antibiotics but can have serious health consequences if left untreated.
Human Immunodeficiency Virus (HIV). HIV is associated with AIDS. This virus attacks and destroys certain white blood cells (T-helper lymphocytes) that are involved in the immune system. As the number of these cells is reduced, the ability of your body to fight off infections also decreases. This eventually results in death. Although there is no cure, early detection allows for treatment with anti-viral therapies that can help to prolong life.
