Cryptosporidiosis alert for NSW

After a steep recent increase in cryptosporidiosis cases across the state, NSW Health is advising the community not to swim for at least two weeks after they’ve had diarrhoea.​ 

498 cases of cryptosporidiosis have been reported in NSW so far in 2024, compared to the 5-year average of 95 cases for the same time period. 

Cryptosporidiosis is caused by the parasite, Cryptosporidium, which infects the intestine and is a common cause of acute diarrhoea in young children. Other symptoms can include nausea, vomiting, fever, headache, and loss of appetite. 

People who have had diarrhoea should: 

  • avoid swimming for at least two weeks after your symptoms resolve 
  • avoid sharing towels for at least two weeks after your symptoms resolve
  • avoid handling food for at least 48 hours after your symptoms resolve 
  • children who have diarrhoea should be kept home from preschool, childcare or playgroup until 24 hours after the diarrhoea has completely stopped.
