Infectious: Stay Away

An interactive exhibition in Ireland gives visitors a front row seat to the science behind epidemics

By | June 12, 2009

An imposing hazard sign greets visitors approaching the east entrance to Trinity College Dublin (TCD) in Ireland: "__INFECTIOUS: STAY AWAY__." The warning does not appear to be working. In its first month on view, more than 20,000 people visited the linkurl:Science Gallery; in TCD to see linkurl:Cliona O'Farrelly; and linkurl:Luke O'Neill's; free immunology exhibition -- an interactive collection of all things infectious, alarming and down right icky. On a summer day, I visit the exhibit, and I'm accompanied by about 20-30 other visitors, mainly adults with a handful of school kids. "__Infectious__ is more an experience than an education," explains Professor O'Farrelly, a TCD immunologist and co-creator of __Infectious__. "The exhibition allows the public to explore important mechanisms in immunology such as pathogen detection, replication, transmission, resistance and clearing." "People feel alienated by science because the vocabulary has become increasingly complex, but many things can be explained simply," says O'Farrelly. These concepts are represented by a carefully constructed sequence of exhibits that blend complex science with visual art. "We want the public to leave __Infectious__ with a basic understanding of important immunological concepts".

__Photos by Patrick Bolger__ At the entrance, I'm greeted by a team in outbreak gear -- full overalls and face masks -- who insist that I proceed into the decontamination zone. Here, I'm screened and electronically tagged to monitor my infection status throughout my visit. This jarring introduction is perhaps one of the most innovative ideas in __Infectious__ -- the world's first simulation of a live epidemic. The electronic sensor around my neck can communicate and infect other sensors when in close proximity, and by periodically infecting a random visitor with an "electronic virus," the exhibition curators can monitor the spread of that virus as it infects the influx of visitors. As I navigate through __Infectious__, I find a lab bench with several microscopes inviting me to get up close and personal with parasites, bacteria and the bioterrorist's favourite, anthrax. Nearby, a mosaic of Petri dishes lines the wall, each having being kissed by a visitor over the weeks since __Infectious__ opened. A multitude of microorganisms grow in the dishes, some conforming to the outline of lips. I admit, this particular part of the exhibition makes me think twice about being amorous ever again. Suddenly the red light on my electronic tag begins flashing. I have become infected. I give a suspicious glance to the person next to me and make my way to the disinfection station, where an animation representing each visitor and their role in the spread of the virus plays. I stare at this real-time visualisation of the infection kinetics as the ease with which viruses can spread through a crowd hits home. "The tags also simulate resistance," as some people will notice they remain uninfected throughout their whole visit, says O'Farrelly. "This links directly with one of the exhibits where visitors are encouraged to give a DNA sample, which they extract themselves." The samples, which visitors harvest from their saliva, are screened for polymorphisms in Mal, an adaptor protein which binds to TLR4, the receptor for Gram-negative bacterial cell wall component lipopolysaccharide (LPS). Following recognition of LPS, TLR4 recruits Mal and an intracellular signalling cascade is activated resulting in the production of important proinflammatory cytokines. Polymorphisms in the Mal gene are known to be associated with increased susceptibility to diseases such as malaria. TCD researchers will compile the results from the __Infectious__ volunteers for a publication on the ratios of these polymorphisms in the Irish population. Other installations in __Infectious__ allow the visitor to simulate their own epidemic and view the spread through a population or even create a new strain of influenza to infect the world. The similarities to the current swine flu situation are hard to ignore but are entirely coincidental, according to Don Pohlman, the Science Gallery Exhibition Manager. "The ideas were developed before the outbreak of swine flu, but the media attention has probably resulted in increased interest in the exhibition," says Pohlman. The warning banner and the mock decontamination process at the entrance to __Infectious__ is akin to what might be expected were a viral epidemic to become a reality, he explains. "With the hazard signs and intimidating screening process, we are trying to create an atmosphere of confusion and paranoia, because not everything is fully explained to the visitor at the entrance." One of the more abstract themes that the creators of __Infectious__ explore is the concept that mechanisms involved in the detection, transmission, and clearing of viruses parallel human behaviour. Viral transmission can mirror the spread of panic or information through a population, for example. Quirky ideas, gossip and fashion trends mutate, replicate and eventually disperse in much the same way as a viral epidemic. Indeed, on reading this article, you can now become a part of this process. Spread the word. __Rowan Higgs has a BSc in Pharmacology and a PhD in Molecular Immunology from University College Dublin, Ireland. He is currently working as a postdoctoral researcher in the Royal College of Surgeons in Ireland, where his research focus is on the regulation of innate immune pathways that contribute to autoimmunity.__ linkurl:__Infectious: Stay Away__;; will be on view at the Science Gallery, TCD until July 17th.

It appears that the severity of epidemics/pandemics of the past, and their impact/mortality, can be correlated with the S&P 500 index. Epidemics that occurred while the S&P index was above its inflation-adjusted trend line (since the late 1800s), the impact was limited. Those that took place while the index was below the trend line, the mortality was very high. \n\nThe currently announced swine flu pandemic is still quite mild and the S&P index is still way above its trend line. If the S&P500, however, goes below its trend line, the impact of the US population could be dramatic.\n\n

I congratulate the people who have started this.Creating this awareness in India would save many lives especially ofchildren.I was prompted to write this because of what I had seen once a child do here.He was hardly four years old.He was standing in a rubbish dump and picking and eating what he could find edible.The tragic partis that there were adults around who said nothing.Child and adult mortality is therefore very high and a programme like this one would go a long way to prevent infections and death.

This exhibition sounds great and I wish I had the opportunity to visit and take part in the virus infection simulation. Just over a year ago we opened an exhibition called Disease Detectives which is also about infectious diseases. It will be at the Science Museum of Minnesota through the summer and then travel to other institutions around the US. Please checkout for more information!

Rowan Higgs' article has made me want to see the 'STAY AWAY' exhibition in Trinity College Dublin. I'll definately get there before the close in July. \nI like the way the article informs the reader of serious science, in a very readable way. I'm not an expert in this area of science, but picked up several important messages. Thus the article is useful even for those readers who won't be able to get to the exhibition themselves. \nMany thanks to the author.
