Infection is caused by, for example, swimming in a contaminated pool and accidentally swallowing water, or through contact with infected animals. An infected person may spread the parasites to food or surfaces if they don’t wash their hands after going to the toilet; Giardiasis – parasite infection of the bowel. Infection is caused by, for example, drinking contaminated water, handling infected animals or changing the nappy of an infected baby and not washing your hands afterwards; Salmonellosis – bacteria are found in animal faeces.

  Infectious gastroenteritis is caused by viruses, bacteria or parasites. In each case, infection occurs when the agent is ingested, usually by eating or drinking. Some of the common types of infectious gastroenteritis include: Escherichia coli infection – this is a common problem for travellers to countries with poor sanitation. Infection is caused by drinking contaminated water or eating contaminated raw fruits and vegetables; Campylobacter infection – the bacteria are found in animal faeces (poo) and uncooked meat, particularly poultry. Infection is caused by, for example, consuming contaminated food or water, eating undercooked meat (especially chicken), and not washing your hands after handling infected animals; Cryptosporidium infection – parasites are found in the bowels of humans and animals. Infection is caused by, for example, swimming in a contaminated pool and accidentally swallowing water, or through contact with infected animals. An infected person may spread the parasites to food or surfaces if they don’t wash their hands after going to the toilet; Giardiasis – parasite infection of the bowel. Infection is caused by, for example, drinking contaminated water, handling infected animals or changing the nappy of an infected baby and not washing your hands afterwards; Salmonellosis – bacteria are found in animal faeces. Infection is caused by eating contaminated food or handling infected animals. An infected person may also spread the bacteria to other people or surfaces by not washing their hands properly; Shigellosis – bacteria are found in human faeces.

  Infectious causes of diarrhoea […] Viral infections that cause gastroenteritis include rotavirus or norovirus. Viral infections commonly cause vomiting and nausea, along with diarrhoea. Diarrhoea can be caused by viral gastroenteritis, which commonly clears up without needing special treatment after a few days. Bacterial infections that can cause diarrhoea include salmonella, E. coli, and campylobacter. These infections are mostly due to food poisoning. Some bacteria cause food poisoning because of the toxins (poisons) they produce. Vomiting, nausea and abdominal pain may come on within hours if you have food poisoning. Diarrhoea symptoms can take longer to appear. Antibiotics may be prescribed if a specific infection caused by bacteria (such as shigella) has been diagnosed. Parasites, such as those which cause cryptosporidiosis and giardia, are found in streams and lakes. Waterborne parasites can also contaminate swimming pools.

  https://www.cdc.gov/yellow-book/hcp/preparing-international-travelers/travelers-diarrhea.html

  Travelers’ diarrhea (TD) is the most predictable travel-related illness. Attack rates range from 30% to 70% of travelers during a 2-week period, depending on the destination and season of travel. Poor hygiene practices in local restaurants and underlying hygiene and sanitation infrastructure deficiencies are likely the largest contributors to the risk for TD. […] TD is a clinical syndrome that can result from a variety of intestinal pathogens. Bacteria are the predominant enteropathogens and are thought to account for 75%90% of cases. Intestinal viruses account for at least 10%25% of illnesses and are more commonly associated with vomiting. The use of multiplex molecular diagnostic assays has suggested that the contribution of viruses to the overall burden of TD disease is underestimated. Infections with protozoal pathogens are slower to manifest symptoms and collectively account for approximately 10% of diagnoses, predominantly in longer-term travelers.
