International travel and sexually transmitted disease

The provision of sexual and reproductive health information and services to travellers: an exploratory survey of Australian travel medicine clinicians

BACKGROUND

International travel can increase the risk of exposure to infectious diseases including sexually transmissible infections (STI). Pre-travel medical consultation provides an opportunity for travel-related health risk assessments and advice. This study explored how travel medicine clinicians integrate sexual and reproductive health (SRH) services into clinical practice.

METHODS

A convenience sample of travel medicine clinicians completed a cross-sectional survey online or via hard-copy disseminated at an annual national Australian travel medicine conference.

RESULTS

Of the 67 respondents, most (n , 51; 76.1%) had a postgraduate qualification relevant to travel medicine and 55.2% (n , 37) had worked in travel medicine for over 10years. Only 22.4% (n , 15) reported conducting a SRH history/STI risk assessment for all travel patients. STI testing pre-departure was conducted on patient request (48, 71.6%), if symptomatic (32, 47.8%) or based on risk history (28, 41.8%). SRH information pre-departure was most frequently provided if prompted by patient questions (n , 42; 62.7%), or based on the patient's history (n , 37; 55.2%). Over half the sample (n , 40; 59.7%) expressed interest in further training in SRH.

CONCLUSION

Providing and engaging with additional training may assist travel medicine clinicians to take a more proactive approach to SRH consultations and STI testing. Additional research is needed to explore models of care that will allow comprehensive SRH and STI services to be integrated into standard pre- and post-travel care.

Epidemiological, behavioural, and clinical factors associated with antimicrobial-resistant gonorrhoea: a review

Antimicrobial-resistant Neisseria gonorrhoeae is a global public health problem in the 21st century. N. gonorrhoeae has developed resistance to all classes of antibiotics used for empirical treatment, and clinical treatment failure caused by extensively resistant strains has been reported. Identifying specific factors associated with an increased risk of antimicrobial-resistant N. gonorrhoeae might help to develop strategies to improve antimicrobial stewardship. In this review, we describe the findings of 24 studies, published between 1989 and 2017, that examined epidemiological, behavioural, and clinical factors and their associations with a range of antimicrobial agents used to treat gonorrhoea. Antimicrobial-resistant N. gonorrhoeae is more common in older than younger adults and in men who have sex with men compared with heterosexual men and women. Antimicrobial-resistant N. gonorrhoeae is less common in some black minority and Aboriginal ethnic groups than in the majority white population in high-income countries. The factors associated with antimicrobial-resistant gonorrhoea are not necessarily those associated with a higher risk of gonorrhoea.

International travel and sexually transmitted diseases

Despite concerted efforts to control sexually transmitted diseases (STDs) worldwide, they still remain a major public health problem. Out of the 25 organisms known to be transmitted sexually, travelers are at greater risk of acquiring HIV and other STDs in developing countries in view of the high prevalence rates in these countries, particularly after sexual exposure to local commercial sex workers (CSWs). Some of the STDs acquired during international travel are more likely to be resistant to standard antimicrobial regimens for the STDs. HIV, gonorrhoea, syphilis, non-specific urethritis, hepatitis B, hepatitis C, and other STDs are a significant risk for travelers who engage in unprotected sex, especially with overseas CSWs. It is recognized that barrier contraceptives provide considerable protection against STDs, but they are not regarded as 100% protective. Sexual abstinence and sexual monogamy with a 'known' partner carry a much lower risk than the safest of 'safer sex' practices. However, in the event of a sexual exposure to a new partner in the country being visited, prior hepatitis B immunization and the consistent and proper use of a latex condom are strongly advised, followed by proper medical investigations and physical examination on returning home, before sexual activity is resumed.

Health Risks Associated with Visiting Friends and Relatives in Developing Countries

An increasingly large proportion of immigrants to developed countries is arriving from less developed countries in Africa, Asia, and Latin America. When these immigrants return to their country of origin to visit friends and relatives, they are at high risk of acquiring tropical infections, compared with other travelers. Immigrants who return to their country of origin to visit friends and relatives (VFRs) are more likely to travel to rural areas for long periods of time, to consume contaminated food and beverages, and to have more prolonged, intimate contact with local populations. As a group, they are less likely to seek pretravel advice or take antimalarial chemoprophylaxis. This article discusses the increased risk of tuberculosis, malaria, food- and waterborne illnesses, hepatitis A, and HIV and other sexually transmitted infections in VFRs.
