WINSTON-SALEM, N.C. Jan. 31, 2013 Some people with the flu emit more of the air-borne virus than others, suggesting that the current recommendations for infection control among health care providers may not be adequate, according to a new study from researchers at Wake Forest Baptist Medical Center.
The study is published in the Jan. 31 online edition of The Journal of Infectious Disease.
"Our study provides new evidence that infectiousness may vary between influenza patients and questions the current medical understanding of how influenza spreads," said Werner Bischoff, M.D., Ph.D., assistant professor of infectious diseases at Wake Forest Baptist and lead author of the study. "Based on our findings, doctors and nurses may need to wear a fitted respirator even for routine care of flu patients as opposed to just the non-fitted, surgical facemask currently recommended."
In the study, 94 patients at Wake Forest Baptist were screened for flu-like symptoms during the 2010-2011 flu season. Nasal swabs were collected from each patient, and air samples were obtained from within 1 foot, 3 feet and 6 feet of patients during routine care.
Of the 94 patients, 61 tested positive for the flu virus and 26 released influenza into the air. Five of the patients emitted up to 32 times more virus than the others.
"One out of five influenza-emitting individuals released elevated amounts of virus into the environment, pointing to a highly infectious subgroup," Bischoff said. "Additionally, the patients who emitted more virus also reported greater severity of illness."
Medical wisdom is that the flu virus spreads primarily by large particles traveling only 3 to 6 feet from an infected person. Current infection-control recommendations for health care providers have focused on preventing transmission by large particles and have required fitted respirators only during aerosol-generating procedures, such as bronchoscopy, intubation and cardiopulmonary resuscitation.
The Wake Forest Baptist researchers discovered that the majority of influenza virus in the air samples tested was found in small particles during routine care up to 6 feet from the patient's head. These small particles can float in the air for hours and travel relatively long distances, Bischoff said. In addition, the smaller virus particles more readily penetrate the non-fitted protective masks.
Further studies are needed to establish person-to-person transmission of influenza and to determine if "super emitters" actually spread the flu to more people, Bischoff said.

Forget buying software: You can now rent Microsoft Office (cheap!)
2 hrs.
Considering that we can have music, movies, TV shows, Photoshop???even underwear???via some sort of monthly or yearly subscription, it's about time we can finally rent Microsoft Office 365, too.
In exchange for $100 per?year (or $10 per?month), you'll be able to install Office 2013 on up to five PCs, Macs or Windows tablets. You'll have?access to Word, Excel, PowerPoint, OneNote, Outlook, Publisher and Access. Additionally, you'll get an extra?20GB of cloud storage through SkyDrive (on top of the 7GB you already get for free) along with 60 minutes of Skype world calling per month.?
You can still buy Office 2013 the old-school way, though don't expect to see any physical media in the software box; you'll just buy a product code and be sent online to download the actual software. The Home & Student version of that is $140 and is limited to one device (and just Word, Excel, PowerPoint and OneNote); Home & Business is $220 (which includes Outlook as well), and Pro ? with all of the same?apps offered in the subscription ??is $400.
Besides being able to install on up to five devices, there are other benefits to the subscription plan:?Free upgrades to the latest versions of the Office software are included, so you can buy in at any time without worrying about missing the next version. Better still, since the subscription?license covers different types of devices, you don't have to buy a bunch of different versions.?(Besides Mac support, Microsoft has said in the past that this Office 365?license would even?provide you with not-yet-released editions, including a possible iPad version.)
If you have a family with lots going on, it is likely to be a money saver, even when you factor in the deals you get from home/student pricing.?
If you are simply?a power user with a lot of different devices, you'll be able to sync Office 365?documents between them with ease. (And you'll, of course, also be able to share documents quickly, thanks to SkyDrive.)?It doesn't stop with the documents though: Your settings and preferences sync as well. This means that no matter where you sign into Office 365, you'll have the same experience. This is, once again, a great benefit for those who split their time between one too many devices.
Pricing and cloud support aside, the latest Office itself isn't a radical redesign. Everything feels familiar, with some small tweaks. It appears that Microsoft is attempting to reduce the bloat we occasionally experience when it comes to its software suite. Does it succeed? Well, we'll have to use the software for a bit longer to make a solid judgment call in regards to that.
While?the?latest version of the software isn't?lacking anything?from?the?traditional?desktop?view???in fact, our initial impression is that it might be the best version of Office we've used so far???we're still waiting for a finger-friendly tablet version of the?legendary?suite.?Though?it?would?be?a?huge?success?given?the?popularity?of?iPads?and?other?tablets,?Microsoft?isn't?going?to?rush?that?out?in?haste,?because?the?company's?developers?say?they?want?to?get?it?right.
You can snag a free one-month trial of Office 365 through Office.com and we suggest taking advantage of this deal. Odds are that you'll find it feeling comfortable and familiar ? and a little lighter on the checkbook as well.
Want more tech news?or interesting?links? You'll get plenty of both if you keep up with Rosa Golijan, the writer of this post, by following her on?Twitter, subscribing to her?Facebook?posts,?or circling her?on?Google+.

Conservative Hispanic group tells GOP to avoid ?amnesty? label
A conservative pro-immigration reform group has issued talking points to Republican lawmakers, telling them to avoid referring to the U.S. citizen children of illegal immigrants as "anchor babies" or calling for the construction of an "electric fence" on the border, among other things.
The talking points, published by BuzzFeed, went out to Republican lawmakers on the Hill as momentum builds for an immigration bill that would legalize most of the country's 11 million illegal immigrants. The memo urges lawmakers to call them "undocumented immigrants" and to avoid terms such as "aliens" or "illegals," which are seen as offensive and dehumanizing. Another phrase to avoid? "Send them all back."
"Conservatives get a bad rap when it comes to immigration reform because of a few people who say things that can be taken to be offensive," said Jennifer Korn, executive director of the Hispanic Leadership Network, the center-right group that sent the talking points on Monday. "It all means the same thing, but the way you say it matters."
Korn worked in the White House when President George W. Bush attempted to get immigration reform passed in his second term. Two bills?one in 2006, the other in 2007?died after a vocal grass-roots movement emerged in opposition to what it called "amnesty" for illegal immigrants. The amnesty tag stuck, even though both bills would have required any applicant to go through a lengthy legalization process that required him or her to meet certain requirements, like paying back taxes and a fine and learning English. Lawmakers received thousands of phone calls about the bill, Korn remembers, almost all of them strongly against reform.
Korn hopes theses talking points will help avoid the "pitfalls" she saw then.
"Right now what's really giving me heartburn is people saying 'pathway to citizenship,'" she said. "It's not a pathway to citizenship. It's 'earned legal status.' If you want conservative support you have to explain what it is so there's not this knee-jerk reaction of 'No amnesty!'"
Sen. Marco Rubio, a Republican from Florida who's part of a bipartisan group of senators pushing for immigration reform, has used "earned residency" at times in interviews with conservative talk show hosts to describe what immigration reform would provide to qualifying illegal immigrants. Democrats, including Obama, often use "pathway to citizenship" to describe the bill.

MEXICO CITY (AP) ? Two months after President Enrique Pena Nieto took office promising to reduce violent crime, the killings linked to Mexico's drug cartels continue unabated.
Only the government's talk about them has dropped.
Eighteen members of a band and its retinue were kidnapped and apparently slain over the weekend in the northern border state of Nuevo Leon by gunmen who asked them to name their cartel affiliation before they were shot and dumped in a well. Fourteen prisoners and nine guards died in an attempted prison escape in Durango state. Nine men were slain Christmas eve in Sinaloa. In the state of Mexico, which borders the capital, more than a dozen bodies were found last week, some dismembered.
The difference under this administration is that there have been no major press conferences announcing more troops or federal police for drug-plagued hotspots. Gone are the regular parades of newly arrested drug suspects before the media with their weapons, cash or contraband.
Pena Nieto has been mum, instead touting education, fiscal and energy reforms. On Monday, he told a summit of Latin American and Caribbean leaders in Chile that he wants Mexico to focus on being a player in solving world and regional problems.
Some political observers praise him for trying to change the conversation and presenting an alternative face of Mexico. Critics suggest the country's new leaders believe that the best way to solve a security crisis is to create distractions.
"What Pena Nieto is doing is ... sweeping violence under the rug in hopes that no one notices," said security expert Jorge Chabat. "It can be effective in the short term, until the violence becomes so obvious that you can't change the subject."
The Pena Nieto government didn't immediately respond to requests for interviews. Secretary of Interior Jose Osorio Chong had a closed-door meeting with the governors of Mexico's central states about security on Monday. In a press conference afterward, he promised to increase patrols along a highway system already bristling with military and police roadblocks and checkpoints.
The apparent weekend killing of 18 members of Kombo Kolombia, which had played at a private performance late Thursday, was the largest mass kidnapping and killing since 20 tourists disappeared and were later found dead in 2011 near the resort city of Acapulco. Searchers this week were pulling bodies from a well in northern Mexico that they said likely belonged to the band.
An area known as the Laguna, where Coahuila and Durango states meet, has been the scene of numerous battles between factions of the Sinaloa the Zetas cartels.
The State of Mexico has had 70 slayings so far this year, according to Gov. Eruviel Avila. La Familia has moved in from the neighboring state of Michoacan and is fighting for territory with a smaller gang known as the United Warriors. Meanwhile, masked vigilantes patrol towns in the southern state of Guerrero on the Pacific coast, where citizens have grown tired of organized crime usurping local authority.
Communications expert Ruben Aguilar said the Pena Nieto government is right to change the focus from security, which had been the main topic throughout the six-year administration of President Felipe Calderon, who left office on Dec. 1.
"On the subject of security, President Calderon went against all logic and turned it into the country's only issue," said Aguilar, who was spokesman for previous President Vicente Fox. "The theme itself is addictive for the media, and generates a negative social mood."
It's difficult to say if drug violence has risen because the government no longer provides numbers, something that started under Calderon, who last released drug-war death statistics in September 2011.
The newspaper Reforma, one of several media outlets that count murders linked to organized crime, said that in December, the first month of the new government, there were 755 drug-related killings, compared to 699 in November. In Calderon's six-year term, some 70,000 people lost their lives to drug violence, the newspaper reported, with at least 20,000 believed missing.
Pena Nieto's election marked the return to power of the Institutional Revolutionary Party, or PRI, which ran Mexico for 71 years. Under Calderon, violence exploded and cartels splintered. Many Mexicans believed drug violence would start to wane with the return of the PRI, assuming it would negotiate to keep the peace ? something party leaders have consistently denied.
Upon taking office Dec. 1, Pena Nieto announced that he would work to restore peace, saying the government would change its security strategy to reducing murders, kidnappings and extortion more than going after cartel leaders . He released a security plan that was not clearly different from Calderon's. Among the few specifics was a plan to establish a gendarmerie to patrol dangerous areas, a force that will take several years to build. Meanwhile he is keeping the military on the streets, just as Calderon did.
The Pena Nieto government also said that it will only talk about violence in terms of "hard data."
Eduardo S?nchez, the undersecretary for media in the Interior Ministry, told Mexico's official news agency last week that the federal government will no longer present detainees to the media or mention prisoners' aliases ? be it "the Squirrel" or "El Brad Pitt" ? a highly criticized practice under Calderon.
The idea, Sanchez said, is to avoid glorifying violence, which is already celebrated in some circles through music and clothing styles.
"We don't want the youth in this country to feel like crime is attractive or a good place in increase your social economic status," Sanchez told local reporters last week.
He said the government has arrested 854 people for drug-related crimes its first month in office, and said 69 criminals were killed in confrontations with the armed forces. But he would not say to which organized crime groups they belonged or the circumstances of their deaths or capture.
Carlos Reyes, spokesman for the congressional delegation of the opposition Democratic Revolution Party, was critical of the new approach.
"The actions of the government need to be transparent in terms of being precise about the level of the problem and how you're going to address it, not evade or disguise it," he said.
Edna Jaime, director of the policy analysis firm Mexico Evaluates, it's too early to criticize the new government's approach.
"The dynamic of violence is not going to change in a month or a month and half," she said, though she added that the government should have a strategy by now. The narrative will change "when it's accompanied by real change," she added.

>>> and now to our weather, making news again, specifically another huge temperature swing. in the midwest, after a dangerous ice storm yesterday, it felt like spring today. but that's before the coming temperature change of around 50 degrees. weather channel meteorologist chris warren is with us. chris, these numbers are incredible.
>> they really are, brian. an all-time january high in topeka, kansas today. 77 degrees. many southern locations feeling these unusually warm temperature readings, looking at temperatures into the upper 70s in some cases, even 80 degrees in corpus christi . tomorrow potentially even warmer in those spots. and this is why. we have a big area of high pressure , keeping things very warm. but dramatically different by the end of the week. cooler air moving down from canada. this is how it plays out in it chicago. 58 degrees tomorrow, almost 40 degrees cooler by thursday and friday. and brian, this will come at a price. we're looking at the threat for severe weather in the lower midwest and the south, possibly tornadoes tomorrow and wednesday.
