Tears, saliva, vomit, urine or stool may be able to transmit Zika, according to an article on the Becker's Infection Control & Clinical Quality website.
The findings come from a case study of a Utah patient — the first death from the Zika virus in the United States.
The patient's son — who was caring for his ill father — contracted the virus in an unknown manner.
The son reportedly hugged and kissed the patient and helped hold his father when his stool was being cleaned by healthcare workers, the article said.
