Other opportunitiesThe Australian Rotavirus Surveillance Program relies heavily on collaborating pathology laboratories and hospitals, which routinely test faecal specimens for rotavirus. We are continuously looking to expand this network, so that we could have greater access to rotavirus positive samples, thereby …
Our collaborators are asked to store rotavirus positive samples, which we then organise to have sent to our laboratory at the Murdoch Children's Research Institute, in Melbourne, Victoria. If you would like to help our group by sending rotavirus positive stool specimens, please contact us. Your help is much appreciated.

Susie Roczo-Farkas coordinates the Australian Rotavirus Surveillance Program (ARSP), which conducts a nationwide study on the rotavirus types circulating in children around Australia. This program undertakes molecular epidemiological studies on the rotavirus strains prevalent in Australia, which allows us to track seasonal changes in rotavirus strains causing severe disease. In addition, the laboratory is also the WHO regional rotavirus reference laboratory and a WHO Collaborating Centre, and is involved with a range of molecular epidemiological studies to characterise the wildtype rotavirus strain population in several countries throughout the Western Pacific Region.
The introduction and implementation of the national rotavirus vaccine program across Australia will increase the selective pressures on circulating wildtype strains, and may result in the emergence of new rotavirus strains. If this happens, these strains will likely impact vaccination programs. Understanding how vaccine introduction has impacted the circulating rotavirus population by altering the prevalence of common genotypes, selection of antigenic variants and emergence of new or novel types causing disease is the focus of the group’s research. The genetic and biological mechanisms underlying vaccine escape will be studied, providing critical information about the circulating rotavirus population that will help maintain a successful ongoing rotavirus vaccine program. The ARSP have published surveillance data as annual reports in CDI since 1999.
