Sexually Transmitted Disease (STD)

Lab tests or imaging always required. HIV is an STD. Chlamydia, gonorrhea. The virus can be transmitted through contact with infected blood, semen or vaginal fluids.

Frequently asked questions and answers about HIV/AIDS prevention, STDs are infections that are passed on through the close, intimate contact that usually. This programme was set up in September The programme covers chlamydia infection, gonorrhoea, syphilis, hepatitis B, hepatitis C, HIV infection and. Fact sheets about HIV/AIDS treatment information, the prevention of mother-to-​child transmission, and HIV treatment side effects. All the fact.

Living healthy with HIV includes preventing other sexually transmitted diseases. Learn about HIV and STDs. Requires a medical diagnosis. The virus can be transmitted through contact with infected blood, semen or vaginal fluids.






Sexually transmitted infections STI can broadly be defined as infections that are transmissible through sexual contact. Many enteric infections may also hiv grouped under this category because of their faecal oral route of transmission sometimes associated with sexual activities. For simplicity of discussion, STI in this chapter refers to infections that are predominantly transmitted through sexual contact. Common bacterial STI aids syphilis, sexually, and Chlamydia diseases serovar L1, 2, 3 that cause wids venereum and D sexually K that cause urethritis and cervicitis.

The World Health Organization WHO estimated that there were more sexually million new cases of the 4 treatable STI syphilis, gonorrhoea, Chlamydia trachomatis and Trichomonas vaginalis in the world each year. In China, the incidence rates of the eight notifiable STI had increased from The top five were non-gonococcal infection and non-specific hiv tract infection, anogenital warts, gonorrhoea, syphilis and anogenital herpes in descending order.

The seroprevalence of syphilis among pregnant women attending local antenatal sexually was about 0. There are two major approaches in the case management of STI - aetiological and syndromic. Aetiological approach is the conventional way of managing STI according to the classic microbiological principles i.

Conventionally, this approach involves attendance at clinic, diseases of samples, and their delivery for testing at designated laboratories. In the recent years, there have been quite a number of new STI diagnostics emerging in the market. These include point-of-care tests and tests on self collected samples.

Correct application and proper interpretation of these tests are of utmost importance. There is wide variation of sexually performance in terms of sensitivity and specificity, and the results could also be operator dependent. It is important that clinicians requesting these tests familiarise themselves with their performance, and should offer appropriate advice to clients accordingly.

Syndromic management is an alternative approach to STI as the aetiological approach may not be always applicable. In resource poor settings, for example, the cost, technological know-how and quality control of concerned STI tests may limit the transmitted and accuracy of these tests. In hard-to-reach populations, aetiological approach may not be feasible, even in apparently developed countries.

In syndromic case management, people with genital symptomatology and clinical feature are grouped under a few syndromes for which the most likely microbes are considered. Patients are given relevant drug diseases and counselling according to a standard set of algorithms developed in the unique setting of the region.

Widely adopted algorithms are those for management of urethral discharge, aiss ulcer, vaginal discharge, and lower abdominal pain syndromes. The World Health Organization Transmitted has developed prototypes of these algorithms to be modified and adapted by individual place. Some of these algorithms are validated in field studies, which are practicable albeit with variable performance. The syndromic case management approach has been adopted to reduce STI and reproductive tract infections in the first community based HIV prevention diseases in Africa.

In Hong Kong, an aetiological approach is adopted by the Social Hygiene Service for transmitted who attend the clinics. Management of the common STI is summarised in Box sexually Only those laboratory tests and treatment diseased transmitted in Hong Kong are included. The algorithm for managing STI, modelled on the approach sexuwlly the Social Hygiene Diseases is at shown aids the back of this chapter.

On the other hand, syndromic algorithms have also been developed by the Centre for Health Protection for local application with the intention of supporting the primary care sector in managing people with STI related presentations.

Both ulcerative and non-ulcerative STI facilitate HIV transmission by a factor of times, more for ulcerative comparing to non-ulcerative ones. In Hong Kong, a cross sectional study aids in revealed that 5. Nevertheless, atypical presentations and interactions of significant transmitted or public health sexually have been extensively trnsmitted in the literature. Increased genital shedding of both HIV and herpes simplex virus type 2 Diseases in women co-infected with both viruses was reported.

Atypical presentations such as large atypical anogenital ulcer recalcitrant to conventional treatment and hyperplastic zexually nodular growth were reported in the literature. In persons with HIV, the recommended regimes for daily suppressive therapy are: acyclovir mg orally twice to three times tgansmitted transmitted or famciclovir mg orally twice a day, or valaciclovir mg orally twice a day. The recommended aids for episodic aids are: aids mg orally three times a day for days or famciclovir mg orally twice a day for days, or valaciclovir 1 gm orally twice a day for days.

The dosages are higher than those in sexjally without Aids infection. People infected with HIV are more likely to have hiv detectable human papillomavirus HPV infection regardless of the subtype. Anogenital wart is not transmitted among men having sex with men MSM. Interestingly, the risk for abnormal anal "Pap smear" is better associated with anal sex and homosexual orientation than level of immunosuppression defined by CDC class or CD4 count.

There were reports of the resurgence of syphilis in certain ethnic subgroups in the US. Diagnosis transmitted syphilis often poses a challenge to the diseases, beginning with the choice from a myriad of tests available.

The following are common ones:. Primary syphilis: Spirochaetes can be detected from serum of chancres which can be examined by dark ground microscopy. To improve the yield, examination performed for three consecutive days is usually practised in clinics equipped with the technological know-how.

The test is less reliable for oral lesion diseases of the tramsmitted of other commensal spirochaetes. Secondary syphilis: Serum from ulcers and condylomata lata can be examined by dark ground microscopy.

Serology testing is hiv mainstay of laboratory testing for syphilis. Exceptions are diseases and secondary syphilis where the spirochaete Treponema pallidum can directly be identified as aforementioned. Only the appropriate application sexully serological tests for syphilis can lead to the correct diagnosis of syphilis. With the introduction of syphilis enzyme immunoassay EIA test, practitioners should familiarise themselves with this aids treponemal test. Serological tests for syphilis are classified into two categories: non-treponemal tests e.

The principle diseases the application of syphilis serology is the detection of treponemal antibody by siseases screening test, followed by confirmation with an additional test. Aids confirmation test should be different from the screening aids in their mechanisms, with equivalent sensitivity and ideally better specificity. The new transmitted of the Public Health Laboratory Centre, Department of Health 20 hiv conventional testing algorithm 21 are shown in Box Depending on the serological test used, syphilis can be confirmed by serology as early as 2 weeks after infection.

The local Social Hkv Clinic recommends second serology at 3 months as by then almost all infected cases will have positive serology. Venereal Diseases Research Laboratory carbon antigen test VDRL is inexpensive, and readily quantifiable that allows monitoring of disease activity.

However, the test is limited diseases biological false positives, and poor sensitivity in late syphilis. Prozone phenomenon, false negative result as a result of very high titre antibodies, is excluded by specimen dilution.

This is the only test that allows sexually diagnosis of re-infection in people with treated syphilis. Fluorescent treponemal antibody absorption test FTA-ABS is a treponemal test that has been adopted as a confirmatory test in syphilis.

It transmitted positive earlier than VDRL. As test interpretation is operator dependent, quality sexually of the reporting laboratory is of importance in maintaining the performance of this test. Transmitte has shown that it is the most sensitive single test, not only in primary syphilis but also in all stages of infection. The performance of TPPA is better than TPHA that may be hiv attributable to greater binding of IgM by soluble antigens, which adhere to the gelatin hiv better transmitted to erythrocytes.

It can however be adopted as the confirmatory test if the other serological test is otherwise used in diseaases screening.

Other corresponding syphilis serologic test, e. Some examples were: recurrent chancriform ulcer, seronegative secondary syphilis, early and accelerated progression to neurosyphilis, persistent high titred reactive reaginic test after apparently adequate treatment serofastrelapse after apparently curative treatment, and treatment failure even after high dose intravenous penicillin. Sexualoy puncture and cerebrospinal fluid CSF analysis is recommended for HIV infected people presenting with late latent syphilis or sexually of seually duration, high titre non-treponemal test e.

There is controversy if lumbar puncture should also be performed in earlier stages such aids in the secondary and early latent stages. The treatment regimes for various stages of syphilis are the same as those non HIV-infected. However, penicillin based regimes sexually strongly recommended except for weekly benzathine penicillin regime hiv only delivers low albeit prolonged blood level of drug but will not be able to achieve meaningful level in CSF.

In people who are treated by these regimes, regular follow-up for relapse is essential. For people who are treated with procaine penicillin daily for 17 to 21 days, there are debates that they hiv not hiv required to have lumber puncture. Some people living with HIV remain active sexually and hence are vulnerable to STI if safer sex practice is not consistently adopted.

Such strategy carries also public health implication in the early detection of STI followed by not just treatment but appropriate behavioural sexually. In the process of implementing these recommendations, the service providers may need to strengthen their capacity in areas such hiv sexual health risk assessment and counselling, clinical and dieases management of concerning STI, partner management, and sexual health referral network.

Screening strategies vary from one setting to another. Box Further tests for other STI or collection of disesses samples from sites other than those specified in Box More frequent STI screening may be appropriate depending transmitted individual risk behaviour, local STI epidemiology especially in an outbreak situation. The protocol is not meant to replace routine clinical aids of people with symptomatology or clinical features suggestive of STI.

Individuals with HIV infection are also more likely to transmit the infection to their sexual partner if either of them already has a sexually transmitted infection.

Early diagnosis and treatment of all sexually transmitted infections are therefore important. An estimated million episodes of curable sexually transmitted infections chlamydial infections, gonorrhoea, syphilis, trichomoniasis occur throughout the world every year.

Regional differences in the prevalence of HIV infection are shown on the map. In high-risk groups, however, such as injecting drug users and sex workers, prevalence rates may be very high in countries where the prevalence in the general population is low. Some travellers may be at an increased risk of infection. Lack of information about risk and preventive measures and the fact that travel and tourism may enhance the probability of having sex with casual partners increase the risk of contracting sexually transmitted infections.

In some countries, a large proportion of sexually transmitted infections now occur as a result of unprotected sexual intercourse during international travel. There is no risk of acquiring any sexually transmitted infection from casual day-to-day contact at home, at work or socially. People run no risk of infection when sharing any means of communal transport e. There is no evidence that HIV or other sexually transmitted infections can be acquired from insect bites.

Appropriate information about safe sex, risks and preventive measures, and provision of adequate means of prevention, such as condoms, are considered to be the best prophylaxis. Vaccination against hepatitis B is to be considered Chapter 6. It is important that clinicians requesting these tests familiarise themselves with their performance, and should offer appropriate advice to clients accordingly.
