US Adds Two Countries to Zika Virus Travel Warning List - CDC
One out the Zika-positive women gave birth to a baby with severe microcephaly, abnormally small heads and limited brain development that have yet to be confirmed as linked to the virus.

Two others pregnant women were tested positive for brain abnormalities and at least one terminated her pregnancy while two of the other pregnancies ended unexpectedly in the first trimester.

Two women gave birth to apparently healthy infants, and two remain pregnant with no known complications, the CDC said.

Health officials worldwide are still cautious to claim there is a link between infant birth defects and the Zika virus as increases in microcephaly have been reported so far only in Brazil and French Polynesia.

Though the link between Zika and microcephaly is questionable, "the evidence for this is getting stronger by the day," CDC Director Tom Frieden told reporters on a conference call.

The Zika virus may be transmissible through sex long after the carrier was infected, as it remains in the semen. The CDC also said that six women acquired Zika through sex with infected men.

"We did not… anticipate that we would see this many sexually transmitted cases of Zika," Frieden said.

CDC has added more than two dozen countries throughout the Americas, Caribbean and the Pacific to the travel warning list, specifically cautioning pregnant woman to avoid visiting Zika-affected areas.

The Zika virus is known to be transmitted by mosquitos. The current outbreak originated in Brazil in 2015 and later spread across Latin America. At present, several countries including the United States are working to produce a vaccine for the Zika virus.

Zika did a number to tourism in the region as the World Bank has estimated that in 2016, Zika-affected countries would lose $3.5 billion, in other words 0.06 percent of the GDP of Latin America and the Caribbean, as well as due to increased medical costs from the virus.

If the virus proves to cause the birth defects, a microcephaly outbreak is expected to hit Colombia by June, according to estimations of the virus spreading from Brazil.

Scientists claim that it's almost impossible to prove the link as it's a relatively common event. Miscarriages occur during the first trimester of 9 percent  to 20 percent of pregnancies, according to the CDC.

The CDC suspects 10 other cases of Zika in pregnant women that have already took medical tests and await the results.
