Though the seven-month-old boy made a full recovery, health researchers were concerned because of evidence that the virus spread to other members of the multi-family community, who, fortunately, all demonstrated mild or no apparent illness. It has been known for a long time that avian and swine strains of flu can spread to humans, with avian strains appearing to be more dangerous than swine strains; as of late 2007, the avian flu had killed 194 people in 321 cases reported worldwide.
Of the 90 people on the farm tested by the University of Alberta and a team of other researchers with provincial and federal health agencies, 54 were tested for positivity to the flu strain, thought to be of swine origin. Besides the baby boy, four of seven other household members and four of 46 other people living on the farm tested positive. The strain of flu was also detected in one of 10 young pigs on the farm. The child apparently had no direct contact with the swine.
“The concern is that swine viral strains could adapt into a form that results in efficient human-to-human transmission,” said Dr. Joan L. Robinson, a professor at the University of Alberta in Edmonton, Canada, a pediatrician at the Stollery Children’s Hospital, and lead author of the study, which was published recently in the journal Emerging Infectious Diseases. Swine flu in humans is “under-recognized in Canada, but it has the capacity to become a problem,” she added. “Early recognition that swine strains are becoming more virulent might expedite both implementation of ideal infection control precautions for symptomatic cases and vaccine development.”
Rather than workers on livestock farms being responsible for recognizing their own flu symptoms, there should be a public health program in place that leads to specific measures if an unexpected number or severity of cases of flu-like illness occur in swine workers. No health program targeting swine workers currently exists, Robinson notes.

For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material chromium triiodide. In addition, they found a long-sought explanation for the unusual magnetic properties of the material. The journal Science has published the findings.
The use of atomically thin, two-dimensional van der Waals materials promises innovations in numerous fields in science and technology. Scientists around the...
Flexible, organic and printed electronics conquer everyday life. The forecasts for growth promise increasing markets and opportunities for the industry. In Europe, top institutions and companies are engaged in research and further development of these technologies for tomorrow's markets and applications. However, access by SMEs is difficult. The European project SmartEEs - Smart Emerging Electronics Servicing works on the establishment of a European innovation network, which supports both the access to competences as well as the support of the enterprises with the assumption of innovations and the progress up to the commercialization.
It surrounds us and almost unconsciously accompanies us through everyday life - printed electronics. It starts with smart labels or RFID tags in clothing, we...
The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.
Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.
Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...
