Monsters Inside Me - Season 6 Episode 1 There's Something Living In My Knee

A 4-year-old boy literally drowns in his own mucus, being a victim of an outbreak of the Enterovirus D68 virus; a 7-year old scrapes his knee on a rock at the beach, but when his father puts a liquid bandage on it, it causes it to swell the size of an orange – then, his mother squeezes the wound and finds a sea snail (Littorina scutulata) inside; a college student experiences loss of appetite, fatigue, fever, jaundice, and repetitive nightmares that turn into a reality from getting infected with malaria caused by the Plasmodium falciparum parasite after returning from a trip to Ghana.
