Giardiasis parasite causing diarrhoea sees England cases rise

Giardiasis is spread primarily through contact with infected people or animals, but you can also contract it if you eat or drink contaminated items, including water.

Hanna Yusuf, prescribing pharmacist at Chemist4U, has also warned that giardiasis can be passed on through touching contaminated surfaces and by having sex with someone who is infected with the parasite.

The pharmacist said: “The latest figures from the UKHSA showing an 11.4% increase in the number of infections across England show that you need to also be aware of the risks at home.”

Parasite with ‘unpleasant’ symptoms sees cases rise

Symptoms of the parasite “can be very unpleasant” and can last several weeks, Yusuf adds.

Most people experience diarrhoea, stomach cramps, bloating and unexplained weight loss while infected.

You can expect symptoms to last for weeks, which can result in the infected person becoming dehydrated.

Yusuf advises “drinking plenty of fluids” to keep yourself hydrated while ill and you could also add oral rehydration sachets or solutions to replace electrolytes you might have lost while experiencing vomiting and diarrhoea.

How to reduce your risk of contracting giardiasis

Doing some simple things can help you avoid getting giardiasis.

To reduce your risk, you should:

• Wash your hands thoroughly after using the toilet and before preparing food
• Avoid swallowing water when swimming
• Be careful about food and water hygiene when travelling

The pharmacist added: “So, whether you are travelling abroad or in the UK, it is important to be aware of the risks of giardiasis.

“If you suspect you may have giardiasis, seek medical advice.

“Treatment may include medication prescribed by a doctor, particularly if symptoms are persistent or severe, alongside measures to maintain hydration.”
