New concerns about spread of Zika virus

ATLANTA - The Georgia case, a woman likely infected on a recent trip to Colombia, could be the first of more Zika virus cases in the state. But another case, this one in Dallas, Texas, is raising even more questions, about whether Zika virus can be sexually transmitted, and what that means.

The CDC is already urging pregnant women to postpone travel to 30 destinations in Latin America and the Caribbean where Zika virus is actively spreading.  But now their partners may need to take precautions, too.

This as the CDC confirms a patient in Texas -- who'd recently traveled to Venezuela -- passed the virus to a partner through sexual contact.

Until more is known, the CDC says men who have traveled to or live in an area with active Zika virus transmission, should abstain from sex or use condoms during any form of sex for the duration of their partner's pregnancy.

The concern -- is Zika virus -- which is typically so mild most people don't know they're infect -- may be linked to thousands of babies in Brazil born with severe birth defects -- that include brain damage.

Here in Atlanta, there are reports Delta Air Lines is offering to reassign pregnant flight crew members -- and those trying to conceive -- from routes into Zika-affected areas. The airlines says a small number of crew members have requested the switch.

And virus may be able to live in the blood for 28 days; The American Red Cross is now asking donors returning from Latin American or Caribbean to wait 28-days before giving blood.

If they develop symptoms within two weeks of donating, the Red Cross is asking donors to notify the agency so their blood can be pulled and quarantined.

Mosquitoes remain the main transmitter of Zika virus. So, the CDC is urging people traveling to Central and South America and the Caribbean to wear protection to avoid getting bitten by mosquitoes.
