NEW YORK -- The upcoming Olympic games are not likely to have a major impact on the spread of Zika virus, although four developing countries could face a substantially higher risk, according to a new government estimate.U.S. researchers tried to calculate whether the Olympics in Rio de Janeiro, which is in the midst of a Zika epidemic, will lead to outbreaks that wouldnt have happened otherwise. The danger is that infected travelers might be bitten by mosquitoes after return to their home nations, which would potentially spread Zika to other people and spark an outbreak.The Centers for Disease Control and Prevention estimated that 19 countries that currently do not have Zika have the right conditions for outbreaks if it is imported by people returning from the Olympics. But in only four of the 19 countries is the issue considered substantial: Yemen, at the southern tip of the Arabian peninsula, and Chad, Djibouti and Eritrea in Africa.CDC researchers made their predictions based on a range of factors, including air travel patterns between Brazil and other countries and the presence of a tropical mosquito that is the main way Zika spreads to people.The four nations at greatest risk from the Olympics generally have no or very few travelers to Zika outbreak countries. Only a dozen to several dozen people are expected to travel to the Rio games from each of these countries, but those small numbers represent a notable jump from regular traffic volume to outbreak countries, said the CDCs Dr. Martin Cetron, one of the authors of the report.That doesnt mean health officials are predicting outbreaks in those four countries, Cetron added.The Olympics are happening at a colder time of year in Rio, when mosquito activity is at a minimum. If people take precautions against mosquito bites, these four countries could be spared Olympics-related outbreaks, he said.The Olympic and Paralympic games are expected to draw an estimated 350,000 to 500,000 international visitors and athletes from 207 countries. But health officials say that travel this year will account for less than 1 percent of international travel to Zika outbreak countries.Last month, the World Health Organization rejected calls by some to cancel the summer Olympics, saying there is a very low risk the Olympics will accelerate the spread of Zika around the world.The new CDC report seems to confirm that assessment, said Justin Lessler, a Johns Hopkins University epidemiologist who focuses on computational approaches to predict the spread of disease.I think the most important result highlighted in this paper is how insignificant the additional risk of global Zika transmission caused by the Olympics is, Lessler said, in an email.Earlier this year, the WHO declared Zika a global emergency after seeing an epidemic spreading through Latin America and the Caribbean.In most cases, Zika infections cause, at worst, mild symptoms that disappear within a week. But the WHO declaration was driven by a link between infections in pregnant women and the development of severe brain-related birth defects in their fetuses.Health officials have advised pregnant women to avoid travel to Zika outbreak countries, including Brazil while the Olympics are taking place.Zika can also be spread through sex, and health officials are advising condom use and other precautions for travelers.---Online:CDC report: http://www.cdc.gov/mmwrCheap Jerseys Wholesale .

Miller reached right to deflect Mikhail Grabovskis attempt with just over 2 minutes remaining in regulation, and then made two more saves in the shootout Sunday to give the Sabres a 2-1 win over the Washington Capitals. LAS VEGAS -- She became the first American woman boxer to win a gold medal in the London Olympics, then did it again a few months ago in Rio.Nice trinkets, but Claressa Shields has bigger things in mind. Way bigger.A one-in-a-century fighter, Shields said.The brash middleweight from Flint, Michigan, makes her pro debut Saturday night on the undercard of the Andre Ward-Sergey Kovalev light heavyweight title clash. Shell do it without headgear but with the same two-minute rounds as in the amateurs.And she will do it against a familiar opponent in Baltimore boxer Franchon Crews, a top amateur she beat on her way to earning a spot on the 2012 Olympic team.Very seldom do you see someone making their pro debut with this level of fight, said Mark Taffet, who is Shields co-manager. The idea is to use the first year and make it impactful in a way that hasnt been done for a female fighter.Theres no shortage of big plans for Shields, and seemingly no lack of confidence that the 21-year-old can succeed where other women boxers havent. But theres also no guarantee Shields can be a breakout fighter who can bring the kind of interest to the fractured world of womens boxing that Ronda Rousey has to the UFC.It may be a longshot, but thats not stopping Shields from envisioning womens boxing having a different future. She believes she can someday headline pay-per-view cards of her own like Ward-Kovalev at the glittering new T-Mobile Arena on the Las Vegas Strip.I consider myself a pay-per-view attraction now, Shields said. The more you see me box, the more youll like me. I want to fight 12 rounds. If a girl could withstand me for 12 rounds, that would be a good fight.Shields will make her debut in a four-rounder that wont be on the pay-per-view portion of the card. Taffett said her bout, expected to take place with few people in the arena, will be streamed online and put on specialty channels in an effort to get people to buy the Kovalev-Ward card.ddddddddddddCrews also will make her pro debut in the fight. She is an eight-time USA Boxing national champion and a silver medalist at the 2012 world championships.Shields, whose story of rising out of poverty with her fists was the subject of a documentary film after her first gold medal win, said she wants to fight 10 times in the next year to build her resume and get more people interested in her.I believe 150 percent in my boxing ability, she said. I know Im a great fighter. I fight better than 90 percent of the men who box now. I just know that, and Im not at my best yet.Shields was miffed after winning her gold medal in London that she didnt receive the kind of endorsements and attention given gymnast Gabby Douglas. Things were a bit better in Rio, where she became the first American boxer to defend an Olympic title and won the Val Barker Trophy as the tournaments top overall fighter.Instead of continuing to draw a $5,000 monthly stipend from USA Boxing to go for a third gold in Tokyo four years from now, though, she decided to turn pro. Despite womens boxing receiving little attention in recent years and her bout not on pay-per-view, Shields isnt deterred.Taffet, who used to be head of pay-per-view for HBO, said he signed on to help manage her because he is a big believer.Shes going to make her mark not just on womens boxing, but all of boxing like the way weve seen recently in MMA, he said. Its a new world, and theres a new sheriff in town. ' ' '
