"longer rainy seasons some blame on climate change"
Ah, yes, it's global warming. If there's a drought, it's global warming. If there's too much rain, it's global warming. If a disease is spreading, it's global warming. No, wait, it's "climate change". And everyone is supposed to know, without saying it, that man has caused it.
I like the way the writer has both migrants and tourists from the U.S. being equally responsible for bringing the disease to Mexico.
Migrants and tourists — including the many thousands of Americans expected for spring break this year — carry new strains of the virus across national borders, where mosquitoes can spread the disease.
