Flu May Be Spread By Just Breathing

Posted 2 days 9 hours ago by Drugs.com

FRIDAY, Jan. 19, 2018 – In the midst of an especially tough flu season, here's more bad news: Researchers say it may be possible to spread the virus simply by breathing. Until now, it was thought that people picked up a flu virus when they touched contaminated surfaces or inhaled droplets in the air ejected by an infected person's coughs or sneezes. But the new study finds coughs and sneezes may not be necessary to saturate the air with flu virus. In the study, researchers analyzed air around the exhaled breath of 142 people with the flu. "We found that flu cases contaminated the air around them with infectious virus just by breathing, without coughing or sneezing," said study author Dr. Donald Milton, a professor of environmental health at the University of Maryland. "People with flu generate infectious aerosols [tiny droplets that stay suspended in the air for a long time] even when ... Read more

Severe Flu Season Slams All But One State: CDC

Posted 9 days ago by Drugs.com

FRIDAY, Jan. 12, 2018 – The worst flu season in years is only getting worse, with 49 states now seeing widespread misery, U.S. health officials report. "Flu is everywhere in the U.S. right now," Dr. Daniel Jernigan, director of the U.S. Centers for Disease Control and Prevention's influenza division, said during a media briefing Friday. On a map of the United States tracking flu activity, "this is the first year that we have had the entire continental U.S. be the same color," he noted. Only Hawaii and the District of Columbia have been spared widespread flu infection so far, according to the CDC. "There has been a very rapid increase in the numbers of people coming in to see their doctors. The season has started early, and it is probably peaking right about now," Jernigan added. Not only that, but "there is also a rapid rise in the number of people being hospitalized for ... Read more

Severe Flu Season Tightens Its Grip on U.S.

Posted 12 days ago by Drugs.com

TUESDAY, Jan. 9, 2018 – Americans are being hit with one of the worst flu seasons in years, with misery now widespread across 46 states, health officials say. In the West, emergency rooms in California and Arizona are packed with people struck by the flu, and drugs that ease the illness are in short supply as doctors struggle with a sharp spike in cases. Further complicating matters, many hospitals nationwide are struggling with a shortage of bags that contain fluids that deliver medicine to treat dehydrated patients, including flu patients. The reason: many of the bags are produced by factories in Puerto Rico, which is still dealing with power problems caused by Hurricane Maria in mid-November. Meanwhile, flu cases are also widespread across the Northeast, and in Florida health workers are reporting a January surge in severe cases. Virtually no region of the country has been spared, ...

Annual Flu Shots Help Keep Seniors Out of the Hospital

Posted 13 days ago by Drugs.com

MONDAY, Jan. 8, 2018 – The current flu season is shaping up to be a nasty one, but there's good news for American seniors who've gotten their flu shot. New research shows that for older adults, faithfully getting the vaccine each year greatly reduces the odds of catching a flu so severe that it lands you in the hospital. Researchers found that repeated influenza vaccination offers a double benefit in older adults, proving 74 percent effective in preventing intensive-care (ICU) admissions and 70 percent effective in preventing deaths. The findings bolster the notion that although getting a flu shot doesn't always prevent the flu, it can make it milder for those who do catch it, said study author Dr. Jesus Castilla. He's a researcher at the Navarra Institute for Health Research in Pamplona, Spain. "We were surprised by the big magnitude of the vaccine effect in preventing severe ... Read more

Health Tip: Things to Know About This Year's Flu Shot

Posted 22 Dec 2017 by Drugs.com

-- The American Academy of Pediatrics recommends that all kids get the annual flu shot. Each year, up to 20 percent of the U.S. population gets the flu and more than 200,000 people are hospitalized, the academy says. Here's the group's list of things to know about the flu shot: The flu vaccine is recommended for all children. The shot should be given during autumn. This year's vaccine should be obtained only in the form of a shot. The inhaled mist is not recommended this year. You cannot get the flu from the flu shot. You may still get the flu if you were vaccinated, but it will be milder than if you hadn't been given the shot. There are more than 165 million doses of the flu vaccine available this year. The flu vaccine does not cause autism. You can get the flu vaccine at the same time as other vaccines. Read more

Flu Shot Safe Even With an Egg Allergy

Posted 19 Dec 2017 by Drugs.com

TUESDAY, Dec. 19, 2017 – It's safe for people with an egg allergy to get a flu shot, says a leading U.S. allergists' group. Doctors no longer need to question patients about egg allergy before giving the vaccine, according to an updated guideline from the American College of Allergy, Asthma and Immunology. "When someone gets a flu shot, health care providers often ask if they are allergic to eggs," said guideline lead author Dr. Matthew Greenhawt. "We want health care providers and people with egg allergy to know there is no need to ask this question anymore, and no need to take any special precautions," said Greenhawt, chair of the college's food allergy committee. The guideline is consistent with recommendations from the U.S. Centers for Disease Control and Prevention and the American Academy of Pediatrics. The "overwhelming evidence" since 2011 has shown that a flu shot poses no ... Read more

Flu Vaccine Could Work as Well as Last Year's Shot: Study

Posted 19 Dec 2017 by Drugs.com

MONDAY, Dec. 18, 2017 – As the flu barrels across the United States, the good news is that this year's vaccine may work better than many expected. The flu has reached epidemic proportions in seven of the 10 regions in the country, according to Lynnette Brammer, an epidemiologist in the U.S. Centers for Disease Control and Prevention's influenza division. Even more troubling, the same, more severe H3N2 flu strain that was around last year is circulating again this year, she said. That concerned flu experts who had watched the vaccine show only 10 percent effectiveness against the H3N2 strain that circulated in Australia, where the flu season has just ended. But a recent report in the journal F1000 Research found the Australian strain of H3N2 is not identical to the predominant virus circulating in the United States. "The majority of the viruses are well-covered by the vaccine," said ... Read more

Are Men Just 'Babies' When They Get the Flu? Maybe Not

Posted 12 Dec 2017 by Drugs.com

MONDAY, Dec. 11, 2017 – As winter rolls into town, so does the flu and all its miserable symptoms. Yet, doctors and women alike have long noticed that men tend to bemoan those symptoms more than women. The phenomenon even has a name: the "man flu." So, are men just whiny wimps? No, a new analysis out of Canada suggests, because respiratory illnesses may indeed hit men harder than women. According to study author Dr. Kyle Sue, "there are already many physiologic differences between men and women, so it makes sense that we could differ in our responses to cold and flu viruses as well." Sue is a clinical assistant professor in family medicine with the Health Sciences Centre at Memorial University of Newfoundland. "The evidence in current studies points towards men having weaker immune systems than women, especially when it comes to common viral respiratory infections," Sue explained. "Men ... Read more

Tough Flu Season Ahead: Vaccine May Only Be 10% Effective

Posted 7 Dec 2017 by Drugs.com

WEDNESDAY, Dec. 6, 2017 – There's bad news about this year's flu vaccine. The most common type of flu being seen in the United States is influenza A H3N2, the same severe strain that dominated last flu season. And in Australia, where the winter flu season has just wrapped up, this season's vaccine was only about 10 percent effective against the H3N2 strain. "Our vaccine is the same as the one used in Australia," said Lynnette Brammer, an epidemiologist in the influenza division of the U.S. Centers for Disease Control and Prevention. "The vaccine doesn't work as well for H3N2 viruses in general." But she added that a 10 percent effectiveness rate still seems a bit low. Last year, a similar vaccine was 43 percent effective against the H3N2 virus and 48 percent effective overall, according to the CDC. And Brammer added that other types of flu are circulating, including influenza A H1N1 ... Read more

Flu Can Have Dangerous Domino Effect on Older Adults

Posted 3 Dec 2017 by Drugs.com

SUNDAY, Dec. 3, 2017 – Even months after recovering from the flu, older people remain at increased risk for a heart attack, stroke or disability, a doctor who specializes in infectious diseases warns. "We all know about the illness influenza causes – obviously fever and making you feel poorly, aches and pains – and that is because it sets up a systemic inflammatory response," said Dr. William Schaffner. He's a professor of preventive medicine and infectious disease at Vanderbilt University School of Medicine in Nashville. "Not as well known: In the two weeks to a month after you recover from influenza, you have a three to five times increased risk of having a heart attack," Schaffner said in a university news release. "You have a two to three times increased risk of having a stroke. "Nobody wants a heart attack or a stroke, so by preventing flu, you prevent this inflammatory response ... Read more

Getting Annual Flu Shot Won't Weaken Your Immune System

Posted 21 Nov 2017 by Drugs.com

TUESDAY, Nov. 21, 2017 – There's no evidence to support the notion that people who get the flu vaccine every year somehow "weaken" their immune system over time, researchers say. In fact, annual vaccination seemed tied to stronger immune cell activity, according to the Norwegian research team. That's even true for years where the flu shot is a poor match for flu viruses actually circulating, as happened in the 2016-2017 season, the findings suggest. The study was led by Rebecca Cox of the University of Bergen's department of clinical science. Her group tracked the immune system health of 250 health care workers. Some of the participants got the flu shot beginning in 2009 and then every year thereafter, while others only got the shot in 2009, but then no shot between 2010 and 2013. Immune system antibodies that showed activity against the flu "persisted above the protective levels in ... Read more

Flu Shot Could Help Your Kid Avoid Hospital

Posted 18 Nov 2017 by Drugs.com

FRIDAY, Nov. 17, 2017 – There's an easy way for parents to help cut their child's chances of ending up in the hospital with the flu – get them vaccinated, researchers say. For the new study, the Canadian researchers analyzed the medical records of nearly 10,000 children, aged 6 months to under 5 years, over the four flu seasons between 2010 and 2014. All lived in the province of Ontario. Among children fully vaccinated against the flu, those aged 2 to 4 years had a 67 percent reduced risk of hospitalization due to the flu. Those 6 months to 23 months old had a 48 percent reduced risk, the study found. Even those who were partially vaccinated (one dose of flu vaccine during their first flu season) had a 39 percent reduced risk of flu-related hospitalization, according to the study. "Influenza can cause serious illness, especially in young children, but there hasn't been a lot of ... Read more

Will This Year's Flu Shot Be as Weak as Last Season's?

Posted 8 Nov 2017 by Drugs.com

WEDNESDAY, Nov. 8, 2017 – Lots of people came down with influenza last year despite getting a flu shot – and researchers can't promise this season's vaccine will be any more effective. Last year's shot was only 20 percent to 30 percent effective because it was grown in eggs, according to the authors of a new report. The egg process is not unusual. But a mutation in the predominant flu virus, called influenza A H3N2, limited the vaccine's potency, said study co-author Dr. John Treanor. When H3N2 comes in contact with eggs, it changes, making it different from the virus that's circulating, he and his colleagues explained. So last year, when H3N2 was the most common flu virus around, the shot was pretty lousy. And what about the 2017-2018 flu season? "It's too early to say which strain of flu will be predominant this year," said Dr. Daniel Jernigan, director of the influenza division at ... Read more

With Severe Flu Season Lurking, Shots a Must

Posted 27 Oct 2017 by Drugs.com

FRIDAY, Oct. 27, 2017 – Early signs suggest that the United States will see a severe flu season, so it's especially important for Americans to get their shots, health experts say. Australia had its worst flu season on record, and what happens in the southern hemisphere typically predicts what happens in the northern hemisphere, said Kevin Harrod. He is a professor in the University of Alabama at Birmingham's department of anesthesiology and perioperative medicine. "These data tell us that we should see a worse-than-average flu season," Harrod said. This year's vaccines are combating the H3N2 strain and B strains of influenza, according to Harrod. H3N2 viruses cause more severe disease in the elderly and young children, and they are associated with a high hospitalization rate, he noted. The best protection against the flu is vaccination, Harrod said in a university news release. "While ... Read more
