"The level of alarm is extremely high, as is the level of uncertainty. Questions abound. We need to get some answers quickly, " Margaret Chan, director general of the WHO, said in Geneva in a briefing for member countries.

Chan said that the situation today is dramatically different from last year because of the multiplying number of cases and the severity of the symptoms.

Health officials said 23 countries are affected by mosquitoes that are spreading the virus locally. The Centers for Disease Control and Prevention said the United States has 31 confirmed cases in 11 states and the District of Columbia. All are travel-related, the CDC's Lyle Petersen said, and "this number is increasing rapidly." The country also has 20 additional cases because of local transmission in U.S. territories — 19 in Puerto Rico and one in the U.S. Virgin Islands.

In a separate briefing with reporters, U.S. officials said all states here are now required to report Zika cases. As a result, they said they expect to see a sharp increase in reports of travel-related cases. But they reiterated that the United States is unlikely to have the kind of widespread local outbreaks that are taking place in other parts of the Americas.

Global health officials have come under criticism from some public health experts for not moving quickly enough to call an emergency meeting on Zika. They accused the WHO of failing to learn its lesson from the Ebola epidemic of 2014, when the agency delayed sounding the alarm for months.

“What you have seen from this administration is a response consistent with the kind of threat that could be out there. At this point, here in the United States, the risk of disease spread by mosquitos are quite low," he said. "The temperatures in North America right now are inhospitable to the mosquito population. Eventually that will change and we have to be mindful any possible risk here in the United States.”	“What you have seen from this administration is a response consistent with the kind of threat that could be out there.

Brazil is the epicenter of Zika, and public health officials are investigating a link between the virus and a rare brain defect called microcephaly in infants, as well as a nervous system syndrome known as Guillain-Barré that can lead to paralysis.

During a briefing to the WHO executive board on Thursday, Brazil’s health minister, Claudio Maierovitch, said the country is investigating 12 confirmed deaths of babies born with microcephaly for potential linkage with Zika virus infection. The country has more than 4,000 suspected cases of microcephaly. Some of those have turned out not to be microcephaly, but many of them have been confirmed through ultrasound, he said. He did not provide a figure. Pregnant women who tested positive for the Zika virus have had a rash and fever during the “first and second parts of their pregnancy,” he said.

Several countries, such as El Salvador, have been so shaken by the reports that they have taken extreme measures by advising women of childbearing age to wait six months to two years before trying to become pregnant. Bruce Aylward, assistant director-general of the WHO, said the group's position is that women who are pregnant should engage in "an abundance of caution" to avoid being bitten by mosquitoes.

Marcos Espinal, director of communicable diseases and health analysis for the Pan American Health Organization, said Zika is likely to spread to the same areas where dengue exists and predicted that “we can expect 3 to 4 million cases of Zika virus disease.”	Marcos Espinal, director of communicable diseases and health analysis for the Pan American Health Organization, said Zika is likely to spread to the same areas where dengue exists and predicted that “we can expect 3 to 4 million cases of Zika virus disease.”

The WHO said the reason Zika appears to be spreading so rapidly is two-fold: One, because it is a new disease to the region, the population does not have immunity, and two, the Zika virus is primarily transmitted by a mosquito species known as A. aegypti, which lives in every country in North and South America except Canada and Chile.

Previous outbreaks of Zika occurred primarily in areas with small populations -- a distinction from the situation in Brazil, where the virus is circulating in densely populated urban areas.

CDC deputy director Anne Schuchat told reporters Thursday that living conditions in the United States, such as better air conditioning and more window screens, are factors that make it much less likely for a widespread outbreak of Zika. But mosquito control is difficult even in this country, and she said state and local authorities need to be vigilant to "jump in" if there are locally transmitted cases.

She said the Food and Drug Administration is also looking into whether any additional guidance is necessary regarding blood donations. Zika virus stays in the blood for only a few days, and "most people have cleared it by about a week," she said.

WHO officials said that this type of mosquito also has been simultaneously carrying a host of other viruses — dengue, Chikungunya, yellow fever, West Nile — to those regions in recent years. Among the hypotheses scientists are looking into are whether the recent severe reactions may be related to co-infection with Zika and another virus, or previous exposure to one.

	There has been one reported case that the virus could have been transmitted through sex, and another case in the medical literature where the virus was found in semen two weeks after symptoms of infection, according to the CDC's Schuchat.
	"But the science is clear that Zika is primarily transmitted to people through the bite of an infected mosquito," she said. "That is really where we are putting our emphasis."
Part of the challenge with Zika is that it is often "silent," with up to 75 percent of infected patients having no symptoms, said Sylvain Aldighieri, who works in epidemic alert and response for the WHO/PAHO. "We have big gaps in terms of confirmation of the real situation."

Representatives from several countries raised concerns about whether we’re seeing a potentially more virulent mutated virus in the Americas, but WHO officials said tests so far show that it’s “very similar” to what was circulating in the Pacific region several years ago.

WHO officials said that better diagnostic tests are in the works, as well as possible antiviral therapies and vaccines, but that any of these could take months to develop. Meanwhile, efforts are focused on controlling the spread of the virus by eliminating mosquito populations. In some countries, health officials have been going door to door to spray for mosquito breeding grounds and have launched public education campaigns to urge people to wear repellent clothing or use sprays. In a controversial experiment, a British company has announced it would release genetically modified mosquitoes whose larvae ~~die~~ to see if they can help stop the spread of the virus.
