“Please provide evidence that EV-D68 is any more prevalent in Central America than anywhere else.”

Only a fool would NOT be suspicious of disease crossing the border illegally. Our government can always be trusted to lie about the problems their border policy causes. Disease is one of them, along with bedbugs and other creepy critters.
