Scientists discover Zika virus in saliva, urine

- Now Brazilian officials are saying that pregnant women should think twice before giving a kiss — especially to strangers.

The president of Brazil's top health research agency says the discovery of active Zika virus in saliva merits special precaution with pregnant women because of suspected links between Zika and birth defects.

Paulo Gadelha suggested pregnant women avoid kissing people other than a regular partner or sharing cutlery, glasses and plates with people who have symptoms of the virus.

He adds, though: "This is not a generalized public health measure, for the love of God."

Scientists at the Fiocruz institute say they're trying to determine if the body fluids can spread Zika to new patients.
