The lifecycle of tapeworms, or Cestoda, involves multiple hosts and stages, from egg to adult worm. Understanding this cycle is crucial for preventing infections in humans and livestock. Tapeworms can cause symptoms like weight loss and abdominal discomfort, with diagnosis often through stool tests. Proper cooking of meat and hygiene are essential in breaking the infection cycle, highlighting the importance of public health education.
