Crying Zika: Virus Material Found in Tears

When an animal is infected with Zika, the virus can spread to the eyes, and genetic material from the virus can find its way into the tears, according to a new study in mice. The finding raises the possibility that people might contract Zika through contact with the tears of an infected person, the researchers said. In the new study, the researchers did not find live Zika virus in the tears of mice.
