WASHINGTON — President Barack Obama is asking Congress for more than $1.8 billion in emergency funding to help fight the Zika virus. In an announcement Monday, the White House said the money would be used to expand mosquito control programs, speed development of a vaccine, develop diagnostic tests and improve support for low-income pregnant women.
Zika virus disease is mainly spread by mosquitoes. Most people who catch it experience mild or no symptoms. But mounting evidence from Brazil suggests that infection in pregnant women is linked to abnormally small heads in their babies — a birth defect called microcephaly.
