Stamina is no problem either: an oriental rat flea was once clocked jumping once a second for three days non-stop.
In the past the disease caused the deaths of millions, particularly during the Middle Ages when it is estimated that three-quarters of the population of Europe was wiped out in one epidemic It was caused by the Bacillus pestis, which is transmitted by the rat flea.
