Cryptosporidium Outbreak (Crypto)
At Thomastown Recreation & Aquatic Centre, the well-being of our patrons is our top priority. We are taking every precaution to address this situation promptly and comprehensively to maintain a safe swimming environment for all. Thank you for your understanding and cooperation during this time.
What is Crypto?
Cryptosporidium (Crypto) is a germ that poses a risk to swimmers. When an individual infected with Crypto swims in a pool, the water can become contaminated with this germ. Subsequently, other swimmers may ingest the contaminated water, leading to potential infection. Symptoms of Crypto infection typically include watery diarrhea, stomach cramps, bloating, vomiting, and fever.
Thomastown Recreation & Aquatic Centre always maintains water treatment measures to protect pool users from germs and debris. However, Crypto germs are known to survive normal levels of pool chlorine and can persist in pool water despite regular disinfection measures.

Why is the pool closed?
Thomastown Recreation & Aquatic Centre is working with City of Whittlesea and the Department of Health and Human Services to manage the presence of Cryptosporidium in the pool.
Even tiny amounts of Cryptosporidium in the water can make you sick, so the facility is closed to clean the pool.
Thomastown Recreation & Aquatic Centre has taken this action to protect your health and to stop the spread of germs.
What is Cryptosporidium?
Cryptosporidium is a tough germ that can be spread when recently infected swimmers contaminate the water with tiny amounts of the germ present on their body.
Cryptosporidium lives in the bowel and is found in the faeces (poo) of infected people. The germ is normally spread through poor hygiene (such as not washing), usually ingesting contaminated foods or water.
Cryptosporidium is highly contagious. One person infected with Cryptosporidium can pass enough germs in a single visit to contaminate a large swimming pool. The germs are highly resistant to chlorine, the usual form of pool disinfection. Up to 50,000,000 of the germ can be found in a single millilitre of faeces. Swallowing as few as two of the germs can lead to infection.

Have I / has my family been exposed to germs while swimming at your pool?
When someone has a confirmed case of Cryptosporidiosis, the person’s doctor must notify the Department of Health. A departmental or local government health officer may contact the patient to find out where they may have picked up the bug. If cases can be linked to a swimming pool, the facility management are notified immediately and begin to take action to prevent the further spread of germs.
Cryptosporidium is a tough germ that can be spread when recently infected swimmers contaminate the water with tiny amounts of the germ present on their body. One person infected with Crypto can pass enough germs in a single visit to contaminate a large swimming pool. That is why we are taking action to close the pool and to treat the water – to ensure no one else gets sick.

I feel unwell after swimming, what should I do?
If you think you or your child may have Cryptosporidiosis, contact your doctor. The doctor will ask you for a stool (faeces or poo) sample for testing. If the results of the tests show that you have cryptosporidiosis, the doctor will be able to provide you with advice and will also notify the Department of Health and Human Services.
Please let our aquatics management know if you become aware of faeces in our pool or if you become ill after swimming at our facility.

How long should I avoid swimming if I have had crypto infection?
Unfortunately, people with Crypto infection can remain infectious for up to 14 days after their symptoms finish. The normal rule of not to swim if you have diarrhoea does not fully protect our pools from Crypto infection, you have to stay away from swimming in pools for 14 days after symptoms finish if you have had Crypto.
We advise all pool users that if you have any symptoms of gastro, this could be a sign of Crypto infection and you should consider seeing your doctor for a simple stool test. If you recently had diarrhoea, you should not swim until 14 days have passed since your last symptoms, because you might have Crypto and not realise.
Is the water safe to swim in once you reopen the pools?
Yes, the pools are safe for swimming in once the process has been completed. The hyperchlorination process is proven to inactivate Cryptosporidium germs. As a precaution Thomastown Recreation & Aquatic Centre is treating these pools to ensure if any germs are present that they are destroyed so visitors are safe to swim in our facility.
We are all responsible for keeping our pools clean and free from germs that can cause illness and pool closures. Go to the Better Health Channel to find out more about healthy swimming actions you can take to help keep the pool clean.

I thought you used chlorine to kill germs in the pool. Why doesn’t chlorine kill the germs?
Germs such as bacteria, viruses and parasites may enter swimming pools when contaminants are brought into the water. You share the pool water with others, and practicing good hygiene before going swimming can prevent germs on swimmers’ bodies from contaminating pool water.
Most pools have treatment systems in place to kill germs. Depending on the type of germ and how long it takes for the germ to be killed, sometimes visitors can get sick when they come in contact or swallow small amounts of contaminated water.
Chlorine is able to kill most germs, but it doesn’t happen straight away. Some germs such as Cryptosporidium can live in pool water for days. Without your help, even the best maintained pools can spread germs.
