Increasing ventilation within aircraft cabins can reduce the spread of infectious diseases in-flight, suggests a review published in this week’s issue of The Lancet.
Mark Gendreau (Lahey Clinic Medical Centre, MA, USA) and colleagues reviewed data from studies looking at the transmission of diseases during commercial air travel. They found that while commercial airlines are a suitable environment for the spread of pathogens carried by passengers or crew, the environmental control systems used in commercial aircraft seem to restrict the spread of airborne pathogens. Proper ventilation within any confined space reduces the concentration of airborne organisms, with one air exchange removing 63% of airborne organisms suspended in that particular space. Computer models of data from an in-flight tuberculosis investigation reveal that doubling ventilation rate in the cabin reduced infection risk by half.
Investigations of in-flight transmission of tuberculosis suggest that the risk of disease transmission to other symptom-free passengers within the aircraft cabin is associated with sitting within two rows of a contagious passenger for a flight time of more than 8 h. This is believed to be relevant to other airborne infectious diseases. However, in one outbreak of SARS, passengers as far as seven rows away from the source passenger were affected.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
