Barmah Forest virus infection
Case defi nition – Barmah Forest virus
infection
Only confirmed cases are reported.
Confirmed case: Requires isolation of
Barmah Forest virus, OR detection of Barmah
Forest virus by nucleic acid testing, OR IgG
seroconversion or a signifi cant increase in
antibody level or a fourfold or greater rise in
titre to Barmah Forest virus, OR detection of
Barmah Forest virus-specifi c IgM.
There were 1,052 notifi cations of Barmah Forest
virus (BFV) infection notifi ed to NNDSS in 2004,
which accounts for 18 per cent of the total mosquitoborne
disease notifi cations for the reporting period.
Eighty-nine per cent of BFV notifi cations were
reported from Queensland (n=535) and New South
Wales (n=402).
The highest rates of BFV notifi cations were reported
by Queensland (13.8 cases per 100,000 population),
the Northern Territory (11 cases per 100,000
population) and New South Wales (6 cases per
100,000 population). The national BFV notifi cation
rate was 5.2 cases per 100,000 population which
was the third highest since 1999. Figure 49 shows
that there was a peak in the BFV notifi cation rate in
Queensland in March 2004 (26.6 cases per 100,000
population). The Northern Territory reported a peak
