From shrieks in bucket to laughter, Brazil Zika baby improves

BONITO, Brazil - It's 3:30 am, and Jose Wesley Campos giggles nonstop as his mother plays with the toddler's thick glasses while preparing to take him to a doctor's appointment three hours away.

"Sometimes, it is as if he swallowed a clown," said his mother, Solange Ferreira.

That is a stark contrast from a few years ago, when Jose, who was born with an abnormally small head amid an outbreak of the Zika virus in northeast Brazil, would shriek uncontrollably. Desperate, Ferreira would calm the boy by putting him in a bucket of water.
