How the scourge that slaughtered entire continents is now a minor worry:
A second Yosemite National Park campground will be shut down for five days after a pair of dead squirrels were found to be infected with the plague, park and California public health officials said on Friday.
The closure of Tuolumne Meadows Campground comes a week after a child who camped elsewhere in Yosemite, one of America’s top tourist destinations, was taken to hospital with the disease.
The case marked the first time a human was known to be infected with the centuries-old scourge, which is carried by rodents and the fleas that live on them, in California since 2006.
Different explanations abound: we’re all in general healthier. There’s fewer rodents around us in cities. There’s damn few fleas around. Or people and their genes likely to get plague are dead and out of the population.
Dunno myself, any other ideas?
