After the H1N1 "swine flu" virus jumped from pigs to human in 2009, more than 18,000 people died and the Centers for Disease Control and Prevention called it the first global pandemic in more than 40 years.

Today, biomedical engineers out of Brown University and Memorial Hospital in Rhode Island hope that their prototype flu detector biochip will help contain the next major flu outbreak by enabling the quickest, most accurate, and most affordable diagnosis possible.

The team's assay, which they call SMART (short for A Simple Method for Amplifying RNA Targets), consists of a series … Read more

Only about half of kids ages 6 months to 17 years received the flu shot in the 2010-2011 season, which may be one reason influenza remains one of the most common causes of hospitalization among kids today, according to a study in this week's issue of the Journal of the American Medical Association.

So researchers from Columbia University and beyond tested an intervention program on a randomized control trial of more than 9,000 kids of that same age range at four community-based clinics in the United States, where more than 7,500 kids had not received the vaccine … Read more

During the H1N1 flu pandemic of 2009, which spread across more than 200 countries and killed more than 18,000 people, it became clear that flu diagnosis was often taking too long and resulting in frequent false negatives.

Today, researchers from Boston University, Harvard, and the Beth Israel Deaconess Medical Center are reporting in the journal PLoS ONE that they have built a microfluidic chip that rivals in accuracy the gold-standard diagnostic test known as RT-PCR but is faster, cheaper, and disposable.

For their four-year study, which involved 146 patients with flu-like symptoms and was funded by the National Institutes … Read more

Poor mail carriers. Not only do they have to put up with threatening dogs and foul weather, but they spend their days touching what may be one of our dirtiest everyday objects: mailbox handles.

The only worse offender? Gas pump handles.

So says a new study by researchers at hygiene solutions firm Kimberly-Clark Professional, who took more than 350 swabs from a variety of everyday objects in Atlanta, Chicago, Dallas, Los Angeles, Miami, and Philadelphia to measure ATP (Adenosine Triphosphate) levels commonly used to detect contamination.

While they did not distinguish between contamination types (i.e. molds versus bacteria), they … Read more

The explosion of social media has given researchers a lot of data to mine and trends to identify, but two computer scientists at Johns Hopkins University say they've developed sophisticated filtering software that is attracting particular attention from public health officials.

Twitter, which launched five years ago, has already been used by computer scientists to try to track the flu.

But when Johns Hopkins University computer scientists Mark Dredze and Michael Paul devised a method to filter and categorize health-related tweets, they weren't sure what they might find. So they decided to sort the tweets (they filtered 1.… Read more

Scientists at the National Institutes of Health said yesterday they have come up with a computer model they say can predict infection rates of the influenza virus, and it could help people gird up for flu season in the future.

It has been well established in the scientific community that the extent to which a flu virus spreads in a given year is related to how much it has mutated from previous seasons. But these scientists set out to translate that knowledge into something more concrete.

The group looked specifically at data on virus genetics and infection rates from 16 … Read more

Let's face it: the typical tweet in the Twitosphere (if you need help with the vernacular, consult the Twictionary) is about as revelatory as the words going into the cell phone of the girl sitting behind me on the bus last night. The vast majority are meaningless to strangers--and probably even to close friends.

But the sheer volume of Twitter activity (the site is "over capacity" as I type this) turns otherwise banal tweets into telling trends, when scrutinized in the aggregate, and health trends are no exception.

"A microblogging service such as Twitter is a … Read more

When compared to the Centers for Disease Control's national surveillance of influenza lab tests, data from Google Flu Trends is 25 percent less accurate at estimating rates of lab-confirmed influenza infections, according to a new study out of the University of Washington.

The findings are being reported at the American Thoracic Society 2010 International Conference in New Orleans this week.

Google Flu Trends estimates national rates of flu-like activity by monitoring the popularity of certain Google search queries in real time. This method is precisely the problem, because the influenza virus does not always cause influenza-like illnesses. (The researchers … Read more

Google on Tuesday announced a new Maps feature to help make it easier to determine the availability of flu vaccine.

According to the company, users can now visit Google's new flu shot Google Maps page to find out if there is any vaccine available in their area. It partnered with "the U.S. Department for Health and Human Services, their Flu.gov collaborators, and the American Lung Association on the flu shot finder," the company wrote in a blog post.

On the flu shot page, users can input their Zip code or town and find all the … Read more
