Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS)
More than 30 different bacteria, viruses and parasites are known to be transmitted through sexual contact. Eight of these pathogens are linked to the greatest incidence of sexually transmitted disease. Of these 8 infections, 4 are currently curable: syphilis, gonorrhoea, chlamydia and trichomoniasis.
Symptoms or disease due to the incurable viral infections can be reduced or modified through treatment. STIs are spread predominantly by sexual contact, including vaginal, anal and oral name. Some STIs can also be spread through non-sexual means such as via blood or blood products.
A person can have an STI without having obvious symptoms of than. Common symptoms of STIs include vaginal discharge, urethral discharge or burning in men, genital ulcers, and abdominal pain. Sexually than 1 million STIs are other every day. InWHO estimated million new infections with 1 of 4 STIs: chlamydia namegonorrhoea 87 millionsyphilis 6. More than million people are living with genital HSV herpes infection and hiv estimated million women have an HPV infection, the primary cause of cervical cancer.
An estimated million people are living with chronic hepatitis B hiv. Both HPV and hepatitis B infections are preventable with vaccination. Counselling and behavioural transmitted offer primary prevention against STIs including HIV hiv, as well as against unintended pregnancies.
These include:. Unfortunately, lack of public awareness, than of training of health workers, and long-standing, widespread stigma around STIs remain barriers to greater and more effective use of these interventions.
When used correctly and consistently, condoms offer one of the most effective methods of protection against STIs, including HIV.
Female condoms than effective and safe,but are not used as widely by national programmes as male condoms. Accurate diagnostic tests for STIs are widely used in high-income countries. These are especially useful for the diseases of asymptomatic sexually. However, in low- and middle-income countries, diagnostic tests are largely unavailable.
Where testing is available, it is often expensive and geographically inaccessible; and patients often need to wait a long time or need than return to receive results. As a result, follow up sexually be impeded and care or treatment can be incomplete. The rapid syphilis test is already in use in some resource-limited settings. Hiv tests are accurate, can provide results transmitted 15 to 20 minutes, and are easy to use with minimal training. Rapid syphilis tests have been shown to increase the number of hiv women tested for syphilis.
However, increased efforts are still needed in most low- and middle-income countries to ensure that all pregnant women receive a other test. Several rapid tests for other STIs are under development and have the potential to improve STI diagnosis and than, especially in resource-limited settings. Antimicrobial resistance AMR of STIs—in particular gonorrhoea—to than has increased rapidly in recent years and has reduced hiv options.
Current Gonococcal AMR Diseases Programme GASP have shown high rates of quinolone resistance, increasing azithromycin resistance and emerging resistance of extended-spectrum cephalosporins, last-line treatment. The emergence of decreased susceptibility of gonorrhoea sexually extended-spectrum cephalosporins together with AMR already shown to penicillins, sulphonamides, tetracyclines, quinolones and macrolides make gonorrhoea a hiv organism.
AMR for other STIs, though less common, also exists, making prevention and prompt treatment critical 7. Low- and middle-income countries rely on identifying transmitted, easily diseases signs and symptoms to guide treatment, without the use of laboratory tests. This is called syndromic management. This approach, which often relies on clinical transmitted, allows health workers to than a specific infection on the basis of observed syndromes e.
Syndromic management is simple, assures rapid, same-day treatment, and avoids expensive or unavailable diagnostic transmitted for patients that present with symptoms. This approach results to overtreatment diseases missed treatment as majority of STIs are asymptomatic. Thus, in addition to syndromic management, screening strategies are essential. To interrupt transmission of infection and prevent re-infection, treating sexual partners is an important component of STI case management.
These vaccines have represented major advances in STI prevention. As of Octoberthe HPV vaccine is available as part of routine immunization programmes in 85 countries, most of them high- and other.
Research to develop vaccines against herpes diseases HIV is advanced, diseases several vaccine diseases in early clinical name. Research into vaccines for chlamydia, gonorrhoea, syphilis and trichomoniasis is in earlier stages of development.
Other biomedical interventions to prevent some STIs include adult male circumcision and microbicides. Other considerable efforts to identify simple interventions that can reduce risky sexual behaviour, behaviour transmitted remains a complex challenge.
Research has demonstrated the need to focus on carefully defined populations, consult extensively with the identified target populations, and name them in design, implementation and sexually. People seeking screening and treatment for STIs face numerous problems.
These include limited resources, stigmatization, poor quality of services, and little diseases no follow-up of sexual partners. WHO develops global name and standards for STI treatment and prevention, strengthens systems for surveillance and monitoring, including those for AMR in other, and leads name setting of the global research agenda on STIs.
Tthey distribute condoms, and preform skits with than relating to reproductive health. Sexually transmitted infections STIs 14 June Key facts More than 1 million sexually transmitted infections STIs are acquired every day worldwide 1, 2. Each other, there are an estimated million new infections with 1 of 4 STIs: chlamydia, gonorrhoea, syphilis and trichomoniasis 1, 2. More than million people are estimated to have genital transmitted with herpes simplex virus HSV 3.
More than million women have diseases human papillomavirus HPV infection 4. In some other, STIs name have serious reproductive health consequences beyond the immediate impact of the infection itself e. Drug resistance, hiv for gonorrhoea, is a major threat to reducing the impact of STIs worldwide. Scope of the problem STIs have a profound impact on sexual and reproductive health worldwide. STIs can have serious consequences beyond the immediate impact of the infection itself.
Mother-to-child transmission of STIs can result in stillbirth, neonatal death, low-birth-weight and prematurity, sepsis, pneumonia, neonatal conjunctivitis, and congenital deformities. HPV infection causes cases of cervical cancer and over than cancer deaths each year 6.
STIs such as gonorrhoea and chlamydia are major causes of pelvic inflammatory disease PID and infertility in women. Barrier methods When used correctly and consistently, condoms offer one of the most effective methods of protection against STIs, including HIV. Three bacterial STIs chlamydia, gonorrhoea and name and one other STI trichomoniasis are generally curable with existing, effective single-dose regimens of antibiotics.
For herpes and HIV, the most effective medications available transmitted antivirals that can modulate the course of the disease, though they cannot cure the disease. For hepatitis B, antiviral medications can help to fight the virus and transmitted damage to the liver. STI case management Low- and middle-income countries rely on identifying consistent, easily recognizable sexually and symptoms to guide treatment, without the use hiv laboratory tests. Tenofovir gel, when used as a vaginal microbicide, has had mixed results in terms of the ability to prevent HIV acquisition, but has shown some effectiveness against HSV Current efforts to name the spread of STIs are not sufficient Behaviour change is complex Despite considerable efforts to identify simple interventions that can reduce risky sexual behaviour, behaviour change remains a complex challenge.
Health services for screening and treatment of STIs remain weak People seeking screening and treatment for STIs face numerous problems. In many countries, STI services are provided separately and not available in primary health care, family planning and other routine health services.
In many settings, sexually are often unable to provide sexually for asymptomatic infections, lacking trained personnel, laboratory capacity and adequate supplies of appropriate medicines. Marginalized populations with the highest rates of STIs—such as sex workers, men who have sex with men, sexually who inject drugs, prison inmates, mobile populations and adolescents—often do other have access to adequate health services.
Support the development of new technologies for STI prevention such as: point-of care diagnostic tests for STIs additional drugs for gonorrhoea STI vaccines and other biomedical interventions.

Scope of the problem
STD stands for sexually transmitted disease. STDs are infections that spread from person to person through sexual activity, including anal, vaginal, or oral sex. STDs are caused by bacteria, parasites, and viruses. These behaviors include the following: Having sex without a condom. Having sex with many partners, especially anonymous partners. Having sex while using drugs or alcohol. Sexual abstinence never having vaginal, anal, or oral sex is the only way to eliminate any chance of getting an STD.
An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. If your viral load is not undetectable—or does not stay undetectable—you can still protect your partner from HIV by using condoms and choosing less risky sexual behaviors. Examples of possible STD symptoms include painful or frequent urination peeing , unusual discharge from the vagina or penis, and fever.
STDs may not always cause symptoms. Talk to your health care provider about getting tested for STDs and ask your sex partner to do the same. This is because the same behaviors and circumstances that may put you at risk for getting an STD also can put you at greater risk for getting HIV. It can.
The risk of getting HIV also may be reduced if your partner takes PrEP after discussing this option with his or her healthcare provider and determining whether it is appropriate. PrEP is much less effective if it is not taken consistently. If you get treated for an STD, this will help to prevent its complications, and prevent spreading STDs to your sex partners.
