CDC Director Tom Frieden has stated that the estimated cost of care for a baby with the severe microcephaly caused by the Zika virus could be as much as $10 million per child. If 100 babies are born with this severe form of microcephaly caused by Zika, their care will cost the U.S. economy approximately $1 billion – roughly the cost of the bipartisan package passed by the Senate. If the inaction in Congress persists, the U.S. and its territories could easily see dozens or even hundreds of infants born with preventable microcephaly, an outcome that would be not only a human tragedy but a significant economic burden.
