    How do people get infected with bilharzia?
    Folks get infected by swimming, bathing, or wading in freshwater sources like rivers or lakes that are infested with the snails carrying the parasite. When they're in the water, the worm's larvae can penetrate the skin and start their journey inside the human body.
    Can bilharzia be cured?
    Yes, indeed! Bilharzia can be treated with a medication called praziquantel, which kills the worms. However, catching the infection early on makes treatment more effective, so staying alert to symptoms is key.
    What are the symptoms of bilharzia?
    Symptoms can vary but often include a rash or itchy skin shortly after being in contaminated water. Weeks or months later, fever, chills, cough, and muscle aches can kick in. If not treated, it can lead to more serious issues like liver damage or kidney failure.
    Is bilharzia common worldwide?
    Bilharzia is most common in tropical and subtropical areas, especially in Africa, South America, and some parts of Asia. Millions of people are affected globally, making it a major public health concern in certain regions.
    How can one prevent getting bilharzia?
    Avoiding contact with potentially contaminated freshwater is the best bet. If you must enter such waters, wearing waterproof clothing or boots can help. Also, drinking safe or treated water ensures those pesky parasites don't get a chance to make you their host.
    Are children more at risk of getting bilharzia?
    Kids tend to be at higher risk because they're more likely to play in or near contaminated water. Teaching them about the risks and ensuring they avoid unsafe water activities are crucial steps in prevention.
