sexually transmitted diseases (STD) or venereal diseases are becoming more frequent. Most STDs are treatable, but still there is no effective treatment for human immunodeficiency virus (HIV) which causes acquired immunodeficiency syndrome (AIDS) and, eventually, death occurs in most cases.
Although you can get HIV by using contaminated needles or, rarely, blood transfusions, is more likely to be transmitted through sexual contact. The virus is present in semen and vaginal secretions, enters the body through small tears in the vaginal or rectal mucosa during sex. Transmission virus only occurs by intimate contact with blood, semen or vaginal secretions infected. There are reports of HIV transmission to healthcare workers through needle puncture.
sexually transmitted diseases due to chlamydia, gonorrhea, herpes, venereal warts and syphilis are highly contagious. Many of them are spread only through sexual contact. The microorganisms that cause STDs, including HIV, die after a few hours to remain outside the human body. However, none of these infections are spread by casual contact such as shaking hands or sitting on the toilet.
The only sure way to prevent STDs and AIDS is through of sexual abstinence or sexual relations take place exclusively between two uninfected partners. In case of having multiple partners or one of them is infected, l individual is at high risk of contracting a sexually transmitted disease.
CONDOM USE.
The consistent and correct use of latex condoms and avoid sexual practices can decrease the risk of contracting AIDS or other STDs, but condoms do not completely eliminate the risk. Some are made from animal membranes and pores of these condoms "skin" natural can allow the passage of the AIDS virus. We recommend using only latex condoms.
To be effective, the condom must be undamaged, should be applied before genital contact, must remain full until it is removed at the end of sexual activity. Additional lubrication (and this occurs even with condoms lubricated) can work to avoid condom breakage. Should be used only water-based lubricants, the oil-based lubricants can cause the condom to break.
A new female condom can help reduce the risk of contracting an STD. Many forms of contraception in women (such as birth control pills) do not protect against STDs, but the results of studies indicate that use of nonoxynol-9, a spermicide, reduces the frequency of gonorrhea and chlamydia. The joint use of spermicides and diaphragm also helps to kill bacteria.
RISK BEHAVIOR. Different sexual practices
accompany varying degrees of risk for HIV infection. Receptive anal intercourse (passive) is the riskiest, because the damage to the anus and rectum can allow HIV to enter the blood. In this relation, the passive coupler is at much greater risk of contracting HIV than the active coupler, although the latter may acquire gonorrhea and syphilis of the rectum of passive coupler.
The heterosexual vaginal intercourse, especially with multiple partners, carries the risk of contracting HIV. It is thought that the virus spreads more easily from men to women than vice versa.
The sex-oral-genital sex is also a possible means of transmission of HIV, gonorrhea, herpes, syphilis and other STDs.
