We propose a new mathematical model for the spread of Zika virus. Special
attention is paid to the transmission of microcephaly. Numerical simulations
show the accuracy of the model with respect to the Zika outbreak occurred in
Brazil.Comment: This is a preprint of a paper whose final and definite form is with
