CRYPTOSPORIDIOSIS ALERT FOR NEW SOUTH WALES

Following a signifcant rise in cryptosporidiosis cases statewide, NSW Health advises the community to refrain from swimming for at least two weeks after experiencing diarrhoea.

Dr. Jeremy McAnulty, Executive Director of Health Protection NSW, revealed that 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 period.

Cryptosporidiosis is a diarrhoeal disease caused by the parasite Cryptosporidium, commonly affecting young children and manifesting symptoms such as nausea, vomiting, fever, headache, and loss of appetite.

Dr. McAnulty emphasized the need for heightened awareness and precautions among parents, as nearly half of the reported cases involve children under ten years old. The parasite is typically contracted by ingesting water contaminated with Cryptosporidium parasites, which can survive for extended periods even in chlorinated pools.

To mitigate the risk of transmission, individuals who have experienced diarrhoea are advised to refrain from swimming and sharing towels for at least two weeks after symptoms resolve, and to avoid handling food for 48 hours thereafter. Children with diarrhoea should be kept home from preschool, childcare, or playgroup until 24 hours after symptoms cease completely.

To prevent cryptosporidiosis, the public is urged to avoid swimming in estuaries, inland waterways, and ocean beaches during and after heavy rainfall, as well as to refrain from swallowing water while swimming. Additionally, thorough handwashing with soap and water, avoiding untreated water sources, and boiling water before consumption are recommended preventive measures.

The surge in cases has also been observed in Queensland, with further information available at https://www. health.qld.gov.au. For additional details on cryptosporidiosis, visit the NSW Health website.
