The Sickness

The Animorphs' alien friend Ax is in trouble. He's come down with a virus called "yamphut", and it's making him very sick. The Animorphs discover the virus could be deadly — but they can't take an "alien" to the hospital. They need to come up with a plan — or lose their friend forever.
