GENEVA (AP) – The Latest on the Zika virus that is spreading through Latin America (all times local):

2:05 p.m.

A U.S. health official says he doubts the United States is vulnerable to a widespread outbreak of a virus linked to a wave of birth defects in Brazil.

Dr. Anthony Fauci says the Zika virus – suspected of being connected to microcephaly – hopefully can be kept at bay with “mosquito vector control.”

Fauci, who heads the National Institute of Allergy and Infectious Disease, appeared on “CBS This Morning.” He said administration officials do not believe there are major ways of spreading the virus “other than by mosquito bites.”

Health officials suspect that Zika is linked to a wave of birth defects in Brazil in which babies have small heads.

President Barack Obama hosted a meeting of federal health specialists on the issue earlier this week.

The World Health Organization says it is convening an emergency committee on Monday to decide if the Zika virus outbreak should be declared an international health emergency.

At a special meeting on Thursday, WHO Director-General Dr. Margaret Chan said the virus – which has been linked to birth defects and neurological problems – was “spreading explosively.” Chan said although there was no definitive proof that Zika was responsible for a spike in the number of babies being born with abnormally small heads in Brazil, “the level of alarm is extremely high.”

WHO last declared an international emergency over the devastating 2014 Ebola outbreak in West Africa, which ended up killing more than 11,000 people.
