 RIO DE JANEIRO (AP) — Brazil is not sharing enough samples and disease data to let researchers determine whether the Zika virus is, as feared, linked to the increased number of babies born with abnormally small heads in the South American country, U.N. and U.S. health officials say. 
  
 The lack of data is forcing laboratories in the United States and Europe to work with samples from previous outbreaks, and is frustrating efforts to develop diagnostic tests, drugs and vaccines. Scientists tell The Associated Press that having so little to work with is hampering their ability to track the virus' evolution. 
  
 One major problem appears to be Brazilian law. At the moment, it is technically illegal for Brazilian researchers and institutes to share genetic material, including blood samples containing Zika and other viruses. 
  
 "It's a very delicate issue, this sharing of samples. Lawyers have to be involved," said Dr. Marcos Espinal, director of communicable diseases in the World Health Organization's regional office in Washington. 
  
 Espinal said he hoped the issue might be resolved after discussions between the U.S. and Brazilian presidents. He said WHO's role was mainly to be a broker to encourage countries to share. When asked whether the estimate of other scientists that Brazil had provided fewer than 20 samples was true, he agreed it probably was. 
  
 "There is no way this should not be solved in the foreseeable future," he said. "Waiting is always risky during an emergency." 
  
 Last May, as the first cases of Zika in Brazil were emerging, President Dilma Rousseff signed a new law to regulate how researchers use the country's genetic resources. But the regulatory framework hasn't yet been drafted, leaving scientists in legal limbo. 
  
 "Until the law is implemented, we're legally prohibited from sending samples abroad," said Paulo Gadelha, president of the Oswaldo Cruz Foundation, Brazil's premier state-run research institute for tropical diseases. "Even if we wanted to send this material abroad, we can't because it's considered a crime." 
  
 The ban does not necessarily mean foreign researchers can't access samples. Some were shared with the United States, including tissue samples from two newborns who died and two fetuses recently examined by the Centers for Disease Control and Prevention. But a U.S. official said that wasn't enough to develop accurate tests for the virus or help determine whether Zika is in fact behind the recent jump in the number of congenital defects. The spike in cases prompted WHO to declare an international emergency Monday. 
  
 Given the drought of Brazilian samples, public health officials across the world are falling back on older viruses — or discreetly taking them from private patients. 
  
 The U.S. official, who shared the information on condition of anonymity as he was not authorized to speak publicly, said the CDC was relying on a strain taken from a 2013 outbreak in French Polynesia to perfect its Zika tests. U.S. researchers trying to sequence Zika's genetic code have been forced to work with virus samples from Puerto Rico for the same reason, he said. 
  
 In England, researchers are using samples drawn from Micronesia, the site of an outbreak in 2007. The French are using samples from Polynesia and Martinique. In Spain, scientists have a Ugandan strain of Zika supplied by the United States. Even Portugal, Brazil's former colonial master, doesn't have the Brazilian strain; the National Health Institute in Lisbon said its tests relied on a U.S. sample from the 1980s, among others. 
  
 Some researchers are bypassing Brazil's bureaucracy by getting samples sent to them for testing by a private lab, said Dr. Jonas Schmidt-Chanasit, an expert on mosquito-borne diseases at the Bernhard Nocht Institute for Tropical Medicine in Hamburg. 
  
 "It's almost impossible to get samples from the country," Schmidt-Chanasit told AP, referring to Brazil. "It's not going via official government channels. Our source is simply the rich people who want a diagnosis." 
  
 In public, health leaders have been eager to boast about their excellent collaboration. WHO's chief, Dr. Margaret Chan, said after Monday's meeting that Brazil and the United States were working "very closely" on studies. When asked about sample sharing, Dr. Anthony Fauci, the director of the U.S. National Institute of Allergy and Infectious Diseases, told AP: "I don't think it's an issue." 
  
 Behind-the-scenes, it was another story. 
  
 Four officials at the World Health Organization told AP that the Brazilians were starving international partners of up-to-date information. 
  
 "WHO has gotten zero from them, no clinical or lab findings," one of the officials said. 
  
 All four spoke on condition of anonymity because they were talking without authorization. 
  
 Ben Neuman, a virologist at Reading University in England, said thousands of samples — or hundreds at a minimum — were needed to track the virus and determine how it's changing. "Science only works when we share," he said. 
  
 The virus sharing problems aren't limited to Brazil, said Gadelha of the Oswaldo Cruz Foundation. 
  
 "This isn't a unilateral issue; it's a global problem," he said. 
  
 More than a decade ago, WHO faced a similar problem when Indonesia refused to hand over bird flu samples, arguing that Western scientists would use them to make drugs and vaccines the country couldn't afford. 
  
 Lawrence Gostin, director of WHO's Collaborating Center on Public Health Law and Human Rights at Georgetown University, said there are no rules that force governments to hand over viruses, tissue samples or other information. 
  
 "If countries don't share, the only repercussions they face are public condemnation," he said.

Rick Scott declared a health emergency Wednesday because of the arrival of at least nine cases of the mosquito-borne Zika virus in four Florida counties, including Miami-Dade. 
  
 Scott signed the emergency order to cover Miami-Dade, Hillsborough (Tampa), Lee (Fort Myers) and Santa Rosa (Panhandle) counties. Within the past two weeks, health officials have confirmed four Zika cases in Miami-Dade, two in Hillsborough, two in Lee and one in Santa Rosa. 
  
 All nine of the cases stemmed from residents who had recently visited Latin America and the Caribbean, were bitten by a mosquito and unwittingly brought the disease back to the state. Three cases were contracted in Haiti, three in Venezuela, two in Colombia and one in El Salvador, according to state health officials. 
  
 The Pan American Health Organization (PAHO) on Monday added Jamaica and Costa Rica to the list of 24 countries in the Western Hemisphere where the Zika virus has been detected. On Wednesday, Dr. Carissa Etienne, the director of PAHO, requested $8.5 million from the international community to help fight Zika.

 “One fact of which we are unequivocally sure is that the Zika virus — like dengue, chikungunya and yellow fever viruses — is transmitted by the Aedes aegypti mosquito,” Etienne said. “The most effective control measures are the prevention of mosquito bites and the reduction of mosquito populations.” 
  
 While health officials are scrambling to contain the spread of the virus, regional tourism officials are worried about the impact it will have on the multibillion-dollar tourism industry during the crucial winter season. 
  
 “It’s a concern of everyone,” said Guadalupe Monge, a travel agent with Miami-based Costamar Travel. “I’d say 100 percent of our customers are asking about Zika. They want to know how bad it is. Is it safe to travel? Can they change their tickets?” 
  
 The Greater Miami Convention & Visitors Bureau did not return phone calls seeking comment. 
  
 Health officials are particularly concerned about how quickly Zika has spread, as the infected Aedes aegypti mosquitoes have transmitted the virus from person to person. Since first being detected in Brazil last May, more than a million people in Brazil have contracted Zika. 
  
 Zika causes relatively minor symptoms — light fever, a rash, muscle pain and conjunctivitis (red eye). It hadn’t represented a significant health issue — until the Brazilian outbreak. Zika has been linked to a rare neurological disorder called microcephaly, associated with babies being born with smaller brains that do not develop fully. The greatest risk appears to stem from an infection that develops during the first trimester of pregnancy, World Health Organization officials have said. To date, Brazil has reported more than 3,000 suspected cases of microcephaly. 
  
 Zika was long thought to be transmitted only when an infected mosquito bites a person. But health officials in Dallas on Tuesday reported a case of the virus being transmitted sexually by a person who had recently returned to Texas from Venezuela, adding to officials’ concerns. 
  
 Monge, the travel agent, estimates that her agency, which organizes trips and tours throughout the Caribbean and Latin America, has lost about 20 percent of its business as news of Zika has increased. 
  
 The timing is terrible, as Carnival season is picking up and spring break season is around the corner. Both draw tens of thousands to the region. 
  
 Caribbean public health officials launched a new public awareness and health campaign last week geared toward protecting the region’s $29 billion industry. 
  
 “We can never let our guard down where infectious diseases are concerned, and that is particularly so in our tourism-dependent Caribbean region,” Dr. C. James Hospedales, executive director of the Caribbean Public Health Agency, said at a news conference in Trinidad and Tobago, another tourist-dependent nation. 
  
 While the Centers for Disease Control and Prevention has advised pregnant women to postpone trips to infected countries, officials in those countries say others shouldn’t be dissuaded. They suggest taking standard precautions to prevent mosquito bites, including using repellant, sleeping inside and wearing long-sleeved shirts, long pants and hats. 
  
 “Don’t let the mosquito ruin your travel,” the Caribbean Public Health Agency says in a fact sheet on its website. 
  
 Zika is also driving fears about the Summer Olympics in Brazil, considered the epicenter of the Zika outbreak. Since the first case was discovered in Brazil last May, Zika has been found in more than 25 countries and territories in the Americas, plus in American Samoa and Samoa in the Pacific and Cape Verde in Africa. There have been cases in at least 11 U.S. states, including Florida. 
  
 On Tuesday, health officials in Texas announced they had identified a patient in Dallas who had contracted Zika through sex. The patient, identified as Patient 1, is the first known recent case of the virus being transmitted in the United States. Patient 1’s partner, identified as Patient 0, had recently returned to Texas from Venezuela. Dallas authorities said Patient 1 had had no other possible exposure to the virus. 
  
 “Now that we know Zika virus can be transmitted through sex, this increases our awareness campaign in educating the public about protecting themselves and others,” said Zachary Thompson, director of Dallas County Health and Human Services. 
  
 Not everyone is convinced that the virus can be transmitted through sexual contact. 
  
 Dr. George Sealy Massingill, chairman of obstetrics and gynecology at John Peter Smith Health Network in Tarrant County, called the Dallas County sexual transmission a “postulated case.” 
  
 “So far, that’s their best guess how this happened,” he told McClatchy’s Fort Worth Star-Telegram on Tuesday. “It’s hard to go back and say that A caused B.” 
  
 But the CDC has endorsed the sexual transmission theory, a possibility that raises new concerns about the potential for rapid spread of a virus that until last May had been virtually unheard-of in the Americas. 
  
 The Dallas County health department added using condoms to its list of recommendations for anyone returning from an infected area. 
  
 The CDC already recommends that U.S. doctors test newborns who show signs of the Zika virus, especially in states such as Florida, where mosquitoes are a daily nuisance. 
  
 After receiving criticism that it was moving too slowly to address the virus, the World Health Organization on Monday declared the virus a public health emergency. The declaration allows for an organized international response to give countries resources and guidelines on what measures they should be taking.

 The Zika virus is linked to brain deformities in babies and is causing concern among public health officials worldwide. The virus is primarily spread through mosquito bites, but investigators had been exploring the possibility it could be sexually transmitted. 
  
 U.S. health officials say a person in Texas became infected with Zika through sex, in the first case of the illness being transmitted within the United States. |||||
A: 
The Zika virus is now officially a public health emergency in Florida, where at least nine cases have been detected in four counties. Gov. Rick Scott signed the emergency order on Wednesday to cover Miami-Dade, Lee, Hillsborough, and Santa Rosa counties, WESH reports. State health officials say all nine cases involve Florida residents who were bitten by mosquitoes in Caribbean or Latin American countries before returning to the state, reports the Miami Herald. Officials say Haiti and Venezuela are involved in three cases each, two cases were contracted in Colombia, and one originated in El Salvador. On Monday, the World Health Organization called the spread of Zika in the Americas an international emergency. The virus has been linked to the birth of babies with abnormally small heads in Brazil, but health officials from the US and the United Nations say they aren't getting enough information from Brazil to examine the link or track the outbreak, the AP reports. Brazilian law bans the sharing of genetic material like blood samples, and researchers in other countries say they are having to use private samples. "It's almost impossible to get samples from the country," says an expert at Germany's Bernhard Nocht Institute for Tropical Medicine. "It's not going via official government channels. Our source is simply the rich people who want a diagnosis." (Health officials in Texas say they're dealing with a sexually transmitted Zika case.)
