Turns out carrying hard medicines while travelling makes people more prone to pop them against doctor's recommendations. According to a study conducted by the University of Helsinki travellers carrying standby antibiotics take them more often than those travelling without such drugs. Having antibiotics packed in the bags allows their use - against recommendations - also for mild and moderate diarrhoea i.e. cases not requiring medication. Increasing antimicrobial resistance primarily caused by the excessive and uncontrolled use of antibiotics is a globally recognised severe threat to human health. Returning home approximately every third traveller to the tropics carries intestinal multiresistant bacteria.
