Hand, foot, and mouth disease (HFMD). The dreaded scourge of daycares, kindergartens, even occasionally college campuses, and the topic of this week’s episode. From the multiple viruses that cause HFMD to the wide array of symptoms (bye bye, fingernails), from the relatively recent discovery of this disease to the ancient origins of all viruses (deep time, y’all), from the changing nature of outbreaks to the development of potential vaccines (fingers crossed) - in this episode we’re going way beyond the basics of hand, foot, and mouth disease. Whether or not you’ve had the pleasure of being up close and personal with this disease, this episode is sure to leave you slightly horrified/mildly impressed by the infectiousness, longevity, resilience, and deep roots of the HFMD viruses.
