Monsters Inside Me, Series 1

Not all monsters are big. In fact, some of the world’s most deadly organisms are invisible to the naked eye. They are microscopic parasites and they quietly invade their hosts and wait for months or years before striking. A life or death battle between medicine and evolution follows as patients fight off the Monsters Inside Me. A 10-year-old boy mysteriously spikes a high fever after swimming in a warm freshwater lake. An 11-month-old becomes lethargic and unresponsive as something methodically destroys his brain. A group of medical students return from holiday with terrible headaches and meningitis-like symptoms. Family and friends are shocked and worried. Doctors are puzzled, racing to unlock the mysteries before it is too late. What do all these cases have in common? The causes of these mysterious illnesses are not viruses or bacteria but stealthy, cunning creatures that have taken up residence in their unsuspecting hosts — parasites!
