Infectious Diseases, Mayo Clinic, DEAR MAYO CLINIC: How is tapeworm infection contracted and treated? Is it very common today? ANSWER: Tapeworms are flat, ribbonlike worms that can live in human gastrointestinal tracts. Worldwide, an estimated 50 million people have a tapeworm infection. But that number may be low, as the disease often goes unreported.
