Sexually transmitted infections STIalso referred to as sexually transmitted diseases STDare infections that are commonly spread by sexual activityespecially vaginal intercourseanal sex and oral sex. More than 30 different bacteriavirusesand parasites can be transmitted through sexual activity.
The most effective way of preventing STIs is by not having sex. Inabout 1. Until the s, [ citation needed ] STIs were commonly known as venereal diseasesthe word venereal being derived from the Latin word venereus, and meaning relating to sexual intercourse or desire, ultimately derived from Venusthe Roman goddess of love. Not all STIs are symptomaticand symptoms Sexually transmitted disease wikipedia not appear immediately after infection. In some instances a disease can be carried with no symptoms, which leaves a greater risk of passing the disease on to others.
Depending on the disease, some untreated STIs can lead to infertilitychronic pain or death. The presence of an STI in prepubescent children may indicate sexual abuse.
A sexually transmitted infection present a pregnant woman may be passed on to the infant before or after birth. The risks and transmission probabilities of sexually transmitted diseases are summarized by act in the table: Twenty-seven different viruses have been identified in semen.
Information on whether or not transmission occurs or whether the viruses cause disease is uncertain. Some of these microbes are known to be sexually transmitted. Many STIs are more easily transmitted through the mucous membranes of the penisvulvarectumurinary tract and less often—depending on type of infection the mouththroatrespiratory tract and eyes. Mucous membranes differ from skin in that they allow certain pathogens into the body.
The amount of contact with infective sources which causes infection varies with each pathogen but in all cases, a disease may result from Sexually transmitted disease wikipedia light contact from fluid carriers like venereal fluids onto a mucous membrane.
Healthcare professionals suggest safer sexsuch as the use of condomsas a reliable way of decreasing the risk of contracting sexually transmitted diseases during sexual activity, but safer sex cannot be considered to provide complete protection from an STI. The transfer of and exposure to bodily fluids, such as blood transfusions and other blood products, sharing injection needlesneedle-stick injuries when medical staff are inadvertently jabbed or pricked with needles during medical proceduressharing tattoo needles, and childbirth are other avenues of transmission.
These different means put certain groups, such as medical workers, and haemophiliacs and drug users, particularly at risk. It is possible to be an asymptomatic carrier of sexually transmitted diseases. In particular, sexually transmitted diseases in women often cause the serious condition of pelvic inflammatory disease.
The most effective way to prevent sexual transmission of STIs is to avoid contact of body parts or fluids which can lead to transfer with an infected partner. Not all sexual activities involve contact: Proper use of condoms reduces contact and risk. Although a condom is effective in limiting exposure, some Sexually transmitted disease wikipedia transmission may occur even with a condom.
Both partners can get tested for STIs before initiating sexual contact, or before resuming contact if a partner engaged in contact with someone else. Many infections are Sexually transmitted disease wikipedia detectable immediately after exposure, so enough time must be allowed between possible exposures and testing for the tests to be accurate. Certain STIs, particularly certain persistent viruses like HPV, may be impossible to detect with current medical procedures.
Some treatment facilities utilize in-home test kits and have the person return the test for follow-up. Other facilities strongly encourage that those previously infected return to ensure that the infection has been eliminated. Novel strategies to foster re-testing have been the use of text messaging and email as reminders.
These types of reminders are now used in addition to phone calls and letters. Sexually transmitted disease wikipedia counseling is most effective if provided in a nonjudgmental and empathetic manner appropriate to the person's culture, language, gender, sexual orientation, age, and developmental level.
Prevention counseling for STIs is usually offered to all sexually active adolescents and to all adults who have received a diagnosis, have had an STI in the past year, or have multiple sex partners. Such interactive counseling, which
Sexually transmitted disease wikipedia be resource intensive, is directed at a person's risk, the situations in which risk occurs, and the use of personalized goal-setting strategies.
The development of vaccines to protect against gonorrhea is ongoing. Condoms and female condoms only provide protection when used properly as a barrier, and only to and from the area that they cover. Uncovered areas are still susceptible to many STIs.
In the case of HIV, sexual transmission routes almost always involve the penis, as HIV cannot spread through unbroken skin; therefore, properly shielding the penis with a properly "Sexually transmitted disease wikipedia" condom from the vagina or anus effectively stops HIV transmission.
An infected fluid to broken skin borne direct transmission of HIV would not be considered "sexually transmitted", but can still theoretically occur during sexual contact. This can be avoided simply by not engaging in sexual contact when presenting open, bleeding wounds. Other STIs, even viral infections, can be prevented with the use of latex, polyurethane or polyisoprene condoms as a barrier.
Some microorganisms and viruses are small enough to pass through the pores in natural skin condoms, but are still too large to pass through latex or synthetic condoms.
Proper male condom usage entails: In order to best protect oneself and the partner from STIs, the old condom and its contents are be assumed to be infectious. Therefore, the old condom must be properly disposed of. A new condom is used for each act of intercourse, as multiple usage increases the chance of breakage, defeating the effectiveness as a barrier.
Researchers had hoped that nonoxynol-9a vaginal microbicide would help decrease STI risk. Trials, however, have found it ineffective  and it may put women at a Sexually transmitted disease wikipedia risk of HIV infection. Specific age groups, persons who participate in risky sexual behavior, or those have certain health conditions may require screening.
The CDC recommends that sexually active women under the age Sexually transmitted disease wikipedia 25 and those over 25 at risk should be screened for chlamydia and gonorrhea yearly. Appropriate times for screening are during regular pelvic examinations and preconception evaluations. Testing may be for a single infection, or consist of a number of tests for a range of STIs, including tests for syphilistrichomonasgonorrhea, chlamydiaherpeshepatitis and HIV.
No procedure tests for all infectious agents. Early identification and treatment results in less chance to spread disease, and for some conditions may improve the outcomes of treatment. There is often a window period after initial infection during which an STI test will be negative. During this period, the infection may be transmissible. The duration of this period varies depending on the infection and the test.
Diagnosis may also be delayed by reluctance of the infected person to seek a medical professional. One report indicated that people turn to the Internet rather than to a medical professional for information on STIs to a higher degree than for other sexual problems. In the case of rape, the person can be treated prophylacticly with antibiotics. Sexually transmitted disease wikipediait was estimated that million people were infected with either syphilis, gonorrhea, chlamydia or trichomoniasis.
In19 new cases of sexually transmitted infections occurred in women in the United States. The first well-recorded European outbreak of what is now known as syphilis occurred in when it broke out among French troops besieging Naples in the Italian War of — Diamond concludes,"[B]ythe disease had evolved into the disease with the symptoms so well known to us today.
This is where the prostitutes were to be found at that time.
Prior to the invention of modern medicines, sexually transmitted diseases were generally incurable, and treatment was limited to treating the symptoms of the disease. The first voluntary hospital for venereal diseases was founded in at London Lock Hospital.
Ina number of states concluded the Brussels Agreementwhereby states agreed to provide free or low-cost medical treatment at ports for merchant seamen with venereal diseases. The first effective treatment for a sexually transmitted disease was salvarsana treatment for syphilis. With the discovery of antibioticsa large number of sexually transmitted diseases became easily curable, and this, combined with effective public health campaigns against STDs, led to a public perception during the s and s that they have ceased to be a serious medical threat.
During this period, the importance of contact tracing in treating STIs was recognized. By tracing the sexual partners of infected individuals, testing them for infection, treating the infected and tracing their contacts in turn, STI clinics could effectively suppress infections in the general population. In the s, first genital herpes and then AIDS emerged into the public consciousness as sexually transmitted diseases that could not be cured by modern medicine.
AIDS in particular has a long asymptomatic period—during which time HIV the human immunodeficiency virus, which causes AIDS can replicate and the disease can be Sexually transmitted disease wikipedia to others—followed by a symptomatic period, which leads rapidly death unless treated. Contact tracing continues to be an important measure, even when diseases are incurable, as it helps to contain infection.
In sexual harassment case filed against Mitsubishi Motor Manufacturing of America by the Equal Employment Opportunity Commission EEOCa number of male employees referred to sexually transmitted infections as "souvenirs".
