Tourist and Business Traveler

Travel is one of the main ways AMR spreads and is why this issue has such intense global implications. As a traveler, whether you travel for work, leisure, or any other reason, knowledge of AMR is essential to keep both yourself safe while in your destination country, but also to ensure you minimize the risk of spreading drug-resistant bacteria when you return home.

Food Choices

A Swiss study demonstrated that 75% of 38 tourists travelling to India returned home with antibiotic-resistant bacteria in their guts. In addition, 11% of tourists had bacteria resistant to the last-resort antibiotic colistin (Bernasconi O, et al. 2016). While bacteria can spread via the objects you touch or the people you come into contact with, the food choices you make also have a significant impact on the spread of resistant bacteria. Many countries still use antibiotics indiscriminately in animal husbandry; overuse and unnecessary use of antibiotics in the animals we eat increases the risk that antibiotic-resistant bacteria will develop and be passed on to humans through meat or products such as milk and eggs.

Animal-based products are not the only food sources that may be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance genes; ingredients added during food processing can also be vehicles for resistance spread. These ingredients can range from things such as starter cultures, probiotics, and bioconserving microorganisms. When raw food is mixed with other ingredients, cross contamination increases the likelihood that bacteria will spread. While cooking can often kill resistant bacteria, consumption of raw food products creates a substantial risk of transferring antimicrobial resistance to humans. (Verraes et al., 2013).

Hospital Acquired Infections

If you begin to feel sick while abroad it is important to weigh the pros and cons of checking into a local hospital. Hospitals are major hubs for the development of antimicrobial resistant agents, particularly those critical for human health. Even in countries with advanced healthcare systems, hospital acquired infections or hospital associated infections (HAIs) are still prevalent. HAIs are defined as “an infection acquired in hospital by a patient who was admitted for a reason other than that infection” (WHO, 2002). Worldwide approximately 1.4 million people are suffering from an HAI at any given moment; the highest frequency of HAIs is reported in the Eastern Mediterranean and South-East Asia regions (WHO, 2002).

HAIs are one of the leading causes of death in hospitals; on top of that, survivable infections increase the time spent in the hospital to an average of 8.2 days following an infection acquired after surgery (WHO, 2002). For countries without universal healthcare this can lead to devastating economic costs in addition to the physical suffering endured.

Klebsiella pneumoniae is an opportunistic pathogen that can cause respiratory and bloodstream infections in humans; new research has discovered antibiotic-resistant strains of this bacteria are rapidly spreading throughout hospitals in Europe. Certain strains are already resistant to last-resort carbapenem antibiotics, meaning these strains are considered to be extremely drug resistant (XDR) (Nature Microbiology, 2019).

Colistin is used very sparingly in humans as it can cause kidney failure; however, when no other antibiotics have been effective, colistin is an important last resort (AMR Review, 2016). Widespread use of colistin in animals has led to resistance in animal pathogens which has concerning implications for human health. A recent study in China has shown the discovery of transferable colistin resistance in bacteria in both humans and animals (Yi-Yun Liu et al., 2016).

As standard treatments grow increasingly ineffective, infections are becoming more difficult or even impossible to control. This will only increase the number of infections worldwide and drastically compound the problem. The risk of fatality increases when combined with the fact that illnesses will now be more prolonged and hospital stays will also become longer as resistance spreads (WHO, 2014). Information on over-the-counter antibiotic sales are difficult to obtain in many countries and in those where data is available, information is often inconsistent. In the EU, the European Union Council recommended that antibiotics should be used as prescription-only medicines in member states (2002/77/EC); despite this, Some areas in Southern and Eastern Europe consume between 20% and 30% of antibiotics without a prescription (Morgan et al., 2011) (AMR Review, 2016).

Deciding to go to a hospital

  • Does the hospital use single-use equipment (i.e. thermometers)?
  • Does the hospital properly disinfect common use equipment between patients?
  • Are patients with wound drainage or other conditions that increase the risk of contamination placed in private rooms?
  • Do the staff wash their hands frequently? Do they use gloves?
    • Using gloves may be a warning sign for contamination. A study of a 20-bed neonatal unit found glove use without frequent hand washing or disinfecting did not prevent contamination (Monegro, et al., 2019)
  • Are patients walking barefoot? This can increase the spread of bacteria between rooms
  • Are linens changed daily? Are any beds visibly dirty?
  • Medical devices can be a breeding ground for bacteria if not changed regularly; if you require tracheostomies, endotracheal tubes, intravascular lines, foley catheters, insulin pumps, pacemakers, or defibrillators make sure you are attended to regularly and keep an eye out for symptoms of sepsis. Such warning signs include:
    • Fever and chills
    • Very low body temperature
    • Peeing less than normal
    • Rapid pulse
    • Rapid breathing
    • Nausea and vomiting

Before you travel it may be useful to check the following maps to see if your destination has a high rate of resistance to the bacteria Escherichia coli and Klebsiella pneumoniae. These two bacteria are by no means the only infectious bacteria that can be resistant to antibiotics, but they are a good indicator to determine the risk of encountering antibiotic-resistant bacteria during your travels.

Please note that countries in white have no available data.

How can I stay safe while travelling?

No matter where you travel to, there are several general guidelines you should follow. For more specific advice and information visit our travel advice page.

  • Make sure all vaccines are up to date
  • Ask your health care professional if you could benefit from any vaccines specific to your destination country
  • Always use safe sexual practices
  • Maintain good hygiene; wash your hands often and especially prior to eating
  • Learn about ways to treat and prevent common travel-associated illnesses such as travelers’ diarrhea
  • Drink only bottled water
  • Avoid eating street food, particularly meat; use your judgement; if a restaurant or food vendor looks unclean your safest option is to eat packaged foods or stick to restaurants that have clear health and safety standards
  • Avoid eating meat in countries where antibiotics are still used incorrectly in animal husbandry
  • If you become sick while on vacation or after returning home, make sure you seek medical attention and let your healthcare provider know what countries you have been travelling in

If AMR has already been an emerging issue for a long time, why are governments taking so long to act?

There are a number of reasons why governments are slow to react to AMR. For one, AMR is a very complex issue due to its global and multisectoral nature and simple national policy cannot have a strong effect on it. Furthermore, even if there is political will, the public has yet to seize the AMR issue wholeheartedly and demand concrete action from their governments. (Wellcome Trust Fund, 2019).
