Cryptosporidiosis surge Prompts Health Warning: Avoid public Pools After Diarrhoea
victoria is grappling with a sharp rise in cases of cryptosporidiosis, a parasitic infection that causes severe diarrhoea and stomach cramps. The Department of Health has issued a stark warning: individuals who have experienced diarrhoea should avoid public swimming pools for at least two weeks to prevent the spread of the disease.
So far this year, 87 cases of cryptosporidiosis have been reported in Victoria, surpassing the five-year average. This follows a record-breaking 2349 cases in 2024, marking a staggering 233% increase compared to the previous year. While cases typically spike during warmer months, the current figures have raised critically important public health concerns.
Cryptosporidiosis, commonly known as ‘crypto,’ is caused by the parasite Cryptosporidium. It can lead to prolonged illness, particularly in individuals with weakened immune systems. Chief Health Officer Tarun Weeramanthri emphasised that while chlorine effectively kills most germs in treated pools, Cryptosporidium is highly resistant to normal chlorine concentrations.
“It’s important to remember that you remain infectious for several weeks after your diarrhoea stops,” weeramanthri saeid. “So don’t swim until two weeks after your symptoms have stopped. It’s the simple steps that are most effective – showering with soap before swimming will help keep germs out of the water.And of course, avoid swallowing the pool water if you can.”
The Department of Health has outlined five key steps to minimise the risk of spreading cryptosporidiosis:
- Avoid swimming for two weeks after diarrhoea stops if you’ve had cryptosporidiosis or diarrhoea of unknown cause.
- Shower and wash with soap, especially your bottom, before swimming.
- Wash your hands with soap after using the toilet or changing a nappy.
- Change nappies only in designated areas.
- Avoid swallowing pool water.
These measures are crucial to protecting public health, particularly as the warmer months approach and pool usage increases.| Key Recommendations to Prevent Cryptosporidiosis |

For those suspecting they or their child may have cryptosporidiosis, Weeramanthri advises contacting a doctor for testing. Early detection and adherence to these guidelines can help curb the spread of this resilient parasite.
As Victoria faces this growing health challenge, the message is clear: vigilance and hygiene are essential to keeping our pools safe and our communities healthy.
Cryptosporidiosis Surge in Victoria: Expert Insights on Prevention and Public Health Risks

Victoria is facing a notable rise in cryptosporidiosis cases, a parasitic infection causing severe diarrhoea and stomach cramps. With 87 cases reported this year alone—surpassing the five-year average—public health officials have issued urgent warnings to avoid public swimming pools after experiencing diarrhoea. To shed light on this growing health concern, Senior editor Sarah Thompson sits down with dr. Laura Bennett, a leading infectious disease specialist, to discuss the causes, risks, and preventive measures for cryptosporidiosis.
Understanding Cryptosporidiosis: Causes and Symptoms
Sarah Thompson: Dr. Bennett,can you explain what cryptosporidiosis is and what causes it?
Dr. Laura Bennett: certainly, Sarah.Cryptosporidiosis, often referred to as “crypto,” is an infection caused by the parasite Cryptosporidium. This parasite is highly resilient and can survive in various environments, including chlorinated swimming pools. The primary symptoms include watery diarrhoea, stomach cramps, nausea, and sometimes fever. For healthy individuals, the illness may resolve on its own, but for those with weakened immune systems, it can lead to prolonged and severe health complications.
Why Swimming Pools Pose a Risk
sarah Thompson: The Department of Health has warned against swimming for two weeks after diarrhoea stops. Why is this so crucial?
Dr. Laura Bennett: This is critical as Cryptosporidium is highly resistant to normal chlorine levels used in pools. Even after symptoms like diarrhoea subside, individuals remain infectious for several weeks. Swimming during this period can contaminate the water, putting others at risk. Chlorine effectively kills most germs, but cryptosporidium has a protective outer shell that shields it from disinfection, making it especially challenging to eliminate.
Key Steps to prevent the Spread of Crypto
Sarah Thompson: The Department of Health has outlined five key recommendations to prevent the spread of cryptosporidiosis. Can you elaborate on these?
Dr. Laura Bennett: Absolutely. The first and most crucial step is to avoid swimming for at least two weeks after diarrhoea stops. This includes cases of cryptosporidiosis or diarrhoea of unknown cause.Secondly, showering with soap before swimming is essential to reduce the risk of introducing germs into the pool. Third, washing hands thoroughly with soap after using the toilet or changing nappies is crucial to prevent contamination. fourth, nappies should only be changed in designated areas to avoid spreading pathogens. avoiding swallowing pool water is a simple yet effective way to reduce infection risk.
The Role of Public Awareness
Sarah Thompson: Public awareness seems to be a significant factor in controlling the spread. How can individuals and communities contribute?
Dr. Laura Bennett: Awareness is key. Many people aren’t aware that they can remain infectious for weeks after symptoms subside. By following the guidelines and educating others, individuals can play a vital role in protecting public health. Parents, for instance, should be extra cautious with young children, who are more likely to swallow pool water. pool operators can also help by posting clear guidelines and ensuring proper hygiene facilities are available.
What to Do If You Suspect an Infection
Sarah Thompson: What advice would you give to someone who suspects they or their child might have cryptosporidiosis?
dr. Laura Bennett: If you suspect an infection, the first step is to consult a healthcare professional for testing. Early detection is crucial to managing the illness and preventing its spread. While waiting for test results, it’s critically important to stay hydrated, especially if diarrhoea is severe. Most importantly, avoid swimming or allowing your child to swim until at least two weeks after symptoms have resolved.
Conclusion
As Victoria grapples with this surge in cryptosporidiosis cases, the need for vigilance and adherence to hygiene practices has never been more urgent. By staying informed and following preventive measures, individuals can definitely help curb the spread of this resilient parasite and ensure safer swimming environments for everyone.
