Background: The increase of gonococcal infection cases in Europe and rises in Neisseria gonorrhoeae antibiotic resistance (AMR) have become an urgent concern globally. In the last few years international tourism has increased, which might contribute to the spread of different strains of multiresistant gonococcal infections. This study aimed at assessing the effect of international travel on the transmission of multidrug resistant N. gonorrhoeae in the European Union and associated European countries.
Method: We conducted a systematic review and searched PubMed, Scopus, Embase and CENTRAL between January 1, 2010 and June 30, 2021 for gonococcal infection, antibiotic resistance and international travel. Articles were screened in title, abstract and keywords. The quality of the articles was assessed using a pre-designed tool. Individual, travel related and susceptibility to antimicrobials data were collected.
Results: A total of 18 studies met our criteria, of which 88.9% concluded that international travel directly influences the transmission of multidrug resistant N. gonorrhoeae from the country of travel to the country of return. Travelers mainly visited South East Asian countries (66.7%) and returned to the UK (38.9%). Half of the included studies reported ciprofloxacin resistant strains and the most frequently prescribed drug used for treatment was ceftriaxone.
Conclusions: International travels might be an important factor in the spread of multi-resistant sexually transmitted infections (STIs). There is a need to strengthen AMR surveillance in international travelers for prompt investigation and notification of drug resistance in STIs.
