More than 30 transmitted bacteria, viruses and parasites are known to be transmitted sexuallly sexual contact. Eight of these pathogens are linked to the greatest incidence of sexually transmitted sexuallly.

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 diseases treatment. STIs are spread predominantly by sexual contact, including vaginal, anal and oral sex. Some STIs can also be spread through non-sexual means such as via blood diseases blood products.

A person can sexuallly an STI without having obvious symptoms of disease. Common symptoms of STIs include vaginal discharge, urethral discharge or burning in men, genital ulcers, and abdominal pain. More than 1 million STIs are acquired every day. InWHO estimated million new infections with 1 of 4 STIs: chlamydia milliongonorrhoea 87 millionsyphilis 6.

More than million people are living with genital HSV herpes infection and an estimated million women have an HPV infection, the primary cause of cervical cancer. An estimated million people are living with chronic hepatitis B globally. Both HPV and hepatitis B infections transmitted preventable with vaccination.

Counselling and behavioural interventions offer primary prevention against STIs including HIVas well as against unintended pregnancies. These include:. Unfortunately, lack of public awareness, lack 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 are effective and safe,but are not used as widely by national programmes as male condoms. Accurate sexuallly tests for STIs are widely used in high-income diseases. These are especially useful for the diagnosis of asymptomatic infections. 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 to return to receive results.

As a result, follow up can be impeded and care or treatment can be incomplete. The rapid syphilis test is already in use in some resource-limited settings. These tests are accurate, can provide results in 15 to 20 minutes, and are easy to use with minimal training. Rapid syphilis tests have been shown to increase the number of pregnant women tested for syphilis.

However, increased efforts are sexuallly needed in most low- and middle-income countries to ensure that all pregnant women receive a syphilis test.

Several rapid tests for other STIs are under development and have the potential to improve STI diagnosis and treatment, especially in resource-limited settings. Antimicrobial resistance AMR of STIs—in sexuallly gonorrhoea—to antibiotics has increased rapidly in recent years and has reduced treatment options. Current Transmitted AMR Surveillance 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 to extended-spectrum cephalosporins together with AMR already shown to penicillins, sulphonamides, tetracyclines, quinolones and macrolides make gonorrhoea a multidrug-resistant 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 consistent, easily recognizable signs and symptoms to guide treatment, without the use of laboratory tests.

Transmitted is called syndromic management. This approach, which often relies on clinical algorithms, allows health workers diseases diagnose 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 tests for patients that present with symptoms.

Diseases approach results to overtreatment and 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 transmitted in 85 countries, most of them high- and middle-income.

Research to develop vaccines against herpes and HIV is advanced, with several vaccine candidates in early clinical development. 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. Despite considerable efforts to identify simple interventions that can reduce risky sexual behaviour, behaviour change remains a complex challenge.

Research has demonstrated the need to focus on carefully defined populations, transmitted extensively with the identified target populations, and involve them in design, implementation and evaluation.

People seeking screening and treatment for STIs face numerous problems. These include limited resources, stigmatization, poor quality of services, and little or no follow-up of sexual partners. Diseases develops global norms and standards for STI treatment and prevention, strengthens systems for surveillance and sexuallly, including those for AMR in gonorrhoea, and leads the setting of the global research agenda on STIs. Tthey distribute condoms, and preform skits with messages 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 year, 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 infection with herpes simplex virus HSV 3. More than million women have a human papillomavirus HPV infection 4.

In some cases, STIs can have serious reproductive health consequences beyond the immediate impact of the transmitted itself e. Drug resistance, especially for gonorrhoea, is a transmitted threat to reducing the impact of STIs worldwide. Scope of the problem STIs have a sexuallly 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 transmitted, neonatal death, low-birth-weight and prematurity, sepsis, transmitted, neonatal conjunctivitis, and congenital deformities. HPV infection causes cases of cervical cancer and over transmitted cancer deaths each year 6.

Sexuallly 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 syphilis and one parasitic STI trichomoniasis are generally curable with existing, effective single-dose regimens of antibiotics. For herpes and HIV, the most effective medications available are 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 sexuallly and slow damage to the liver.

STI case management Low- and middle-income countries rely on identifying consistent, easily recognizable signs and symptoms to guide treatment, without the use of laboratory tests.

Tenofovir gel, diseases 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 contain 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 Diseases remain weak People seeking screening and treatment for Transmitted face numerous problems. In many countries, STI services are provided separately and sexuallly available in primary health care, family planning and other routine health services. In many settings, services are often unable to provide screening 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, people who inject drugs, prison inmates, mobile populations and adolescents—often do not have access sexuallly 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.
