Laboratory Virology and Serology Reporting Scheme
The Laboratory Virology and Serology Reporting Scheme (LabVISE) is a passive surveillance scheme based on voluntary reports of infectious agents from sentinel virology and serology laboratories around Australia. LabVISE provides data on diagnoses of a number of infectious viruses, parasites and fungi. Interpretation of data from LabVISE is limited by uncertainties regarding its representativeness, lack of denominator data to calculate positivity rates, variable reporting coverage over time and lack of consistent case definitions. LabVISE has an important role in supplementing information of diseases under surveillance in NNDSS and in monitoring infectious agents that are not reported by other surveillance systems.
In 2002, a total of 14 laboratories reported 26,052 infectious agents to LabVISE. This represents a 7 per cent increase from reports received in the previous year (Table 17). The top three reporting laboratories were from South Australia (24%), Western Australia (25%) and Queensland (18%). The two jurisdictions with the largest populations, New South Wales and Victoria, contributed 17 per cent and 12 per cent respectively, to the total reports received by LabVISE (Table 17).

Sixty-six per cent (n=17,251) of all reports received by LabVISE were viral infectious agents, and the remaining 34 per cent (n=8,809) were bacterial or other infectious agents. Among viruses, ortho/paramyxoviruses (influenza, parainfluenza and respiratory syncytial virus) were the most commonly reported (33%; 6,276) followed by herpes viruses (24%; 4,642). Measles, mumps and rubella contributed 11 per cent of reports of viral infections (Figure 64). Among non-viral infectious agents, Chlamydia trachomatis (43%, 3,859), Treponema pallidum (16%, 1,396) and Mycoplasma pneumoniae (13%, 1,232) were the most commonly reported pathogens.
