On Wednesday, Brazil said the number of babies born with suspected microcephaly or abnormally small heads since October had reached nearly 4,000.
The Brazilian authorities believe the increase is caused by an outbreak of the mosquito-borne Zika virus.
Warnings by US health officials now cover parts of Africa and Oceania.
One leading virologist in Brazil told the BBC the country was in an "emergency situation".
Brazil's health ministry says there have been 3,893 suspected cases of microcephaly since October, when the authorities first noticed a surge, up from 3,500 in last week's report.
