For Carnival in Brazil, lots of women don giant feather headdresses and skimpy bikinis.
But for a pre-Carnival event, Elaine Cuoto is dressed as a mosquito — complete with a long proboscis and gossamer wings.
She is part of a group of health workers dancing by a metro station in a working-class neighborhood of Rio's north zone. A few others are wearing mosquito costumes as well. And they're singing a catchy tune:
"If Zika attacks, use this number to report it, 7-4-6. Pay attention!"
