who was designed and developed at HSL, is featured in a
BBC2 programme (broadcast January 28) entitled 'Winter Viruses and How to Beat Them'
Larry has become a bit of household name
around the world recently making appearances on the Discovery News Channel, ABC News, Canadian Broadcast Corporation Radio and
even The Late Show with David Letterman as
well as a host of science and technology websites!
Larry was designed, developed and built by Catherine
Makison-Booth, a research scientist at HSL. He was
conceived in response to a large Norovirus outbreak in the UK
during the winter of 2010/11. His purpose is to help HSL
researchers demonstrate and identify the extent of contamination
during projectile vomiting as experienced by a Norovirus
Larry 'stands' just over five feet tall on a specially designed
frame. His head is a standard training aid used by medical students
to practice intubations and other medical procedures.His oesophagus
is attached to a cylinder (his 'stomach') which is filled with a
fluid to represent stomach contents. The fluid contains a
fluorescent dye which becomes visible under ultra violet light.
During a simulated vomiting episode, the fluid is forcibly
ejected from the cylinder with the aid of an air-pressure system.
Using UV lighting, it is then possible to identify the extent of
the spread of the fluid/vomit.
The system graphically demonstrates the full extent of room
contamination post vomiting and shows that small droplets can
spread over three metres from the "Larry" system. HSL studies have
also shown that Norovirus can be isolated from these small droplets
at concentrations capable of causing an infection. This information
might highlight why this robust and highly infectious virus is
transmitted between people so readily.
The outcomes of these studies have contributed to reviews of
healthcare guidance in hospitals and are due to be published in
relevant journals in the near future.
