ISTM podcast director Dr. Aisha Khatib and digital communications lead Dr. Sarah McGuinness discuss a strange medical case drawn from the pages of the Journal of Travel Medicine. Approximately two billion people around the world are afflicted with toxoplasmosis, a parasitic disease that typically results from exposure to cat feces. Most of those infected don't have any symptoms, but in some cases, the disease can cause muscle aches, fever and swollen glands. So is it possible that the Brazilian traveller contracted toxoplasmosis from the pink dolphins of the Amazon river? (A mini episode.)
