Every summer since West Nile virus’s first U.S. appearance in 1999, Americans have listened to warnings about the mosquito-borne disease and its potentially deadly effects, a severe flu-like fever sometimes accompanied by an even more dangerous brain inflammation. Because the disease—and its attendant worries—recur every year, it’s easy to tune out West Nile coverage. But the Center for Disease Control has announced that this year’s outbreak is shaping up to be one of America’s worst, with the current count at 1,118 cases and 41 deaths.

What’s the News: Global health officials are expected to decide whether to destroy the world’s last caches of smallpox at the 64th World Health Assembly this week. The disease was declared eradicated by the World Health Organization in 1979, but two small stores of the virus remain: one at the Centers for Disease Control and Prevention in Atlanta and one in a Russian government lab.

Now, public health officials are divided on how to ensure that the disease stays eradicated.
