Parasitic Infections

Parasitic infections are caused by parasites, organisms that live on or inside a host and rely on it for nourishment and survival. These parasites can include protozoa, helminths (worms), or ectoparasites like ticks and lice. Infections can occur through contaminated food or water, insect bites, or contact with contaminated soil. Common parasitic infections include:

• Malaria: Caused by the Plasmodium parasite and transmitted by infected female Anopheles mosquitoes. Symptoms include fever, chills, and flu-like symptoms, which can be life-threatening without prompt treatment.
• Toxoplasmosis: Caused by the Toxoplasma gondii parasite, commonly found in cat feces. It can be contracted through contaminated food or water and may cause flu-like symptoms or severe complications, especially in pregnant women and immunocompromised individuals.
• Tapeworm Infections: Result from various species of tapeworms, often through undercooked or contaminated meat. Symptoms can include abdominal pain, weight loss, and nutritional deficiencies.

Treatment usually involves specific medications for the parasite, while prevention includes good hygiene practices, proper food handling, avoiding contaminated water, and using insect repellent.
