What is a parasitic infection?

Parasites are organisms which thrive off their host to survive. They are known to be common amongst travellers, however they are more common in the general population than people may think.

Common parasitic infections found in Western Countries include:





Parasitic infections can be caused by three types of organisms:




Parasitic infections are more likely to occur in those who:

Have compromised immunity, such as people with HIV/AIDS infection.

Live or travel in tropical or subtropical regions of the world

Swim in lakes, rivers, or ponds where Giardia or other parasites are common

Work with soil regularly

Own an outdoor cat - outdoor cats can come into contact with infected rodents and birds. This makes their owners more likely to contract toxoplasmosis, a type of protozoa.

Different types of parasitic infection

Ectoparasites are multi-celled organisms that live on or feed off your skin. They include some insects and arachnids, such as mosquitos, fleas, ticks, and mites.

Gastroenteritis-causing parasites: Gastroenteritis is a condition characterised by irritation and inflammation of the stomach and intestines; this may cause diarrhoea, vomiting and nausea. Infections of the gastrointestinal tract in the form of gastroenteritis are common for certain intestinal parasites, such as Giardia lamblia (Giardia duodenalis, Giardia intestinalis), Cryptosporidium parvum or Cryptosporidium hominis, and Entamoeba histolytica, among others.

Wash, peel, or cook all raw fruits and vegetables

Wash or reheat any food that falls on the floor
