Dengue cases surge in the Americas in potentially worst-ever outbreak -PAHO

Dengue cases in the Americas spiked in the first three months of this year, or by three times the number of infections reported in the same period last year, the Pan American Health Organization said on Thursday.

Brazil, Argentina and Paraguay are the countries most affected by dengue, in what PAHO officials described at a press conference as probably the worst season to date observed in the Americas for the often deadly mosquito-borne illness.
