Water: Is it safe to drink?

Last updated: 22 March 2015


Water is vital for all our lives and drinking adequate amounts of safe water will contribute to good health. Every day, every person needs access to water not only to drink but also for personal hygiene.


People are travelling more often and more widely than ever before, both for work and for pleasure. This means they are often faced with environments that they are unfamiliar with. According to the World Health Organization (WHO), more than 840,000 people are estimated to die each year from diarrhoea as a result of unsafe drinking water, sanitation and hand hygiene.

  • Diarrheal diseases, such as amoebic dysentery
  • Schistosomiasis, a parasitic infection you can get by swimming or bathing in fresh water contaminated with parasites
  • Malaria, dengue and other diseases are spread by mosquitoes that breed in stagnant water
  • Diseases such as legionella, where bacteria are spread by contaminated water droplets.
