Is giardia contagious?

Page last updated 07 July 2020

Yes, giardia is highly contagious and spreads easily from an infected person (who shed billions of parasites in their faeces). People who do not follow proper hygiene or food preparation procedures may accidently contaminate their hands and other surfaces as they battle the diarrhoea giardia causes and inadvertently infect fellow travellers. But it’s not just people who are the problem. It can also be contracted by drinking from untreated water sources where infected animals may have contaminated them, so avoid drinking from untreated water sources such as lakes and streams.

If you have giardia, one important thing you can do is avoid the temptation to use the swimming pool and spa. People who are infected should avoid entering swimming pools or spas for at least one week after their symptoms have stopped.
