Unsafe drinking water is one of the leading sources of health problems when travelling and the ruin of many a holiday. Most travellers have experienced or heard of what is sometimes called Bali Belly, Montezuma’s Revenge or Delhi Belly.
The symptoms are usually diarrhoea, nausea, cramps and bloating.
Escherichia coli (E .coli), Salmonella and Cholera are the most common water-borne bacteria and account for around 80% of these cases.
Protozoa such as Giardia and Cryptosporidium can also be responsible for these symptoms and are usually associated with poor hygiene and sanitation.
In more severe cases viruses like hepatitis, rotavirus and polio can also be a concern.
