assistant
The latest news on the Zika virus is that it has been declared a global health emergency by the World Health Organization. Scientists believe that the Zika virus may be linked to an increase in cases of microcephaly, which is a birth defect that results in babies being born with small heads and incomplete brain development. There is currently no vaccine or treatment for the virus, but researchers are working on developing a vaccine.
