Just wonderful - flu season

From Time magazine:

The Flu May Be Spread Just By Breathing, Study Says
For years, you’ve been told to cover your mouth when you cough or sneeze, especially when you’re sick. But a new study finds that it may be possible to spread the flu just by breathing—no coughing or sneezing required.

“People shed a lot of virus all the time, even when they don’t cough,” says Donald Milton, author of the study published in PNAS and a professor of environmental health at the University of Maryland School of Public Health. “As a result, it’s important to realize you can be infectious at any time.”

During the 2012-2013 flu season, Milton and his colleagues studied 142 University of Maryland students with active influenza, attempting to track how and when they expelled virus particles. During a total of 218 30-minute observation sessions, the students sat in a machine that could measure the droplets they shed while breathing, talking, coughing or sneezing. While coughing did expel some flu particles, the researchers discovered that almost half of the aerosol particles collected in the absence of coughing also contained flu matter, suggesting that simply inhaling germ-ridden air could get you sick.

Joyful news - especially since I am summoned for jury duty this coming week. I'll see how I feel and then give them a call on Monday morning to see if I can get out of it.

Warning: A Flu Pandemic Today Could Kill As Many As 80 Million People
If the 1918 flu pandemic broke out today, it would likely kill at least 62 million people, or slightly more than the number that die in a single year from all other causes combined. The estimate stems from a new tally of flu deaths from 1918 to 1920 in different countries, which varied widely. Based on their findings, authors of the study say that 96 percent of the victims of a present-day pandemic would be in the developing world.

The report comes on the heels of fears that the H5N1 flu virus currently circulating among birds in Southeast Asia and Africa may be the precursor to a deadly global outbreak or pandemic. To gauge the potential threat, researchers reviewed the toll of the most severe previous case, which occurred in 1918 when a flu swept the world, claiming at least 20 million lives. "It's the benchmark against which we worry about future flu pandemics," says population health researcher Christopher Murray of the Harvard Initiative for Global Health.

Just great - we have another - and worse strain - waiting to cross over to humans.
