AIDS has been a
controlled notifiable disease in South Australia since
1983. Cases of AIDS were reported to the Communicable
disease Control Unit until November 1995 when
responsibility for AIDS surveillance was transferred to
the STD Control Branch
(STDCB). AIDS represents the late stage of HIV infection
and consequently surveillance of AIDS does not provide
information on the current epidemiology of HIV infection.A more complete surveillance of HIV
infection was possible in June 1985 when laboratory
testing became available at the IMVS. The IMVS became the
reference laboratory for South Australia and was able to
perform screening EIA and confirmatory Western Blot
assays. Statistics on the number of tests performed and
presumed new diagnoses of HIV infection were compiled by
the Virology Department of the IMVS with assistance from
STD Services. However, The laboratory data had
limited information about risk markers for infection.
HIV infection was proclaimed a
controlled notifiable infection in September 1991 with a
legal requirement on medical practitioners to notifiy
cases of HIV infection. HIV infection is now reported
directly to the STDCB by the State Reference Laboratory
for HIV (IMVS) and a clinical notification is made by the
attending medical practitioner. This notification system
uses a name code and seeks information on demographics,
testing history, risk factors and client preference for
follow up procedures. The attending doctor may
investigate to determine the likely risk factors and
undertake contact tracing; alternatively the client may
be referred to the STDCB. When the clinical notification
indicates the latter option the HIV epidemiologist
contacts the attending doctor to ensure the client is
aware of the referral to the STDCB. The surveillance data
from the laboratory and clinical notifications are
supplemented with information obtained from client
interviews for contact tracing conducted by the HIV
epidemiologist.
The objectives of HIV surveillance
in South Australia are as follows;
- to define the epidemiology of
HIV infection in relation to risk behaviour
- to facilitate contact
tracing/partner notification.
A sound knowledge of the local
epidemiology of HIV provides important information for
education, prevention and treatment programmes.
Understanding current transmission dynamics is especially
important for education and prevention programmes and
depends on identifying incident cases and the risk
behaviours involved. An incident case is defined by the
following;
- Evidence of a prior negative
HIV antibody test in the 12 months prior to
diagnosis of infection,
or
- Diagnosed seroconversion
illness within 12 months of diagnosis of HIV
infection
.Notification forms and reply paid
envelopes are sent to the attending medical practitioner
and additional forms may be obtained from:

Incident cases of
HIV infection in Males in South Australia for the period
01/01/92 - 30/06/96
There have been 175 individuals
diagnosed with HIV infection between January 1992 and
June 1996, 163 (93%) males 12 (7%) females (Table 1.1). Of the 175
reported cases, 53 were classified as incident infections
(50 males, 3 females). The STDCB were able to interview
67% (117/175) of cases including 49/50 of the incident
cases in males. Incident cases represented 31% (50/163)
of reported infections in males and represents the
minimum estimate of incident cases. Some incident cases
will not be detected because of the lack of a sero-conversion illness or prior negative testing. The
median age of incident male cases is 30 years compared to
a median age for all new diagnoses in men of 33.9 years.
The majority (86%) of incident cases were aged between 20
-39 years (Table 1.1).
A high proportion (41/50) of men
who were incident cases reported male to male sexual
contact as their risk factor, 4 men reported sex with
both male and female sexual contacts, 2 men reported
heterosexual contact in a country where HIV infection is
primarily heterosexually transmitted, 2 men reported male
to male sexual contact and injecting drug use as their
risk factors. One male moved interstate shortly after
diagnosis and could not be interviewed to determine his
risk exposure.
Incident cases are interviewed to
determine risk markers for infection and to identify
other potentially infected individuals. The interview is
not designed to determine whether individuals identify as
gay. However, during the interview knowledge of the gay
scene and association with other gay men is assessed. It
is apparent from the interviews that the majority of
incident cases are in gay identifying males. Information
is collected on the knowledge of their partners' HIV
status and where they meet sexual partners. Knowledge of
sexual partners is assessed and recorded in a
hierarchical fashion. Those who know their partners or
their partners' HIV status are recorded as having sex
with known partners, even though they may on occasions
engage in sexual activity with anonymous partners. Those
classified as having anonymous sex reported no sexual
activity with known partners during the time period in
which they were likely to have been infected.
Twenty men (40%) reported anonymous
sexual activity following attendance at a gay venue
and/or the beats. Of those who knew their sexual
partners, 10 reported sexual contact with a known HIV
antibody positive partner and 17 did not know their
partners HIV status (Table
1.2).

There have been 620 individuals
diagnosed with HIV infection, 576 (93%) in males and 44
(7%) in females. Of the males diagnosed, 75% (433)
reported male to male sexual contact, 10% (52) reported
injecting drug use and 5% (27) reported both risk
factors. Injecting drug use was reported by 51% (22) of
the women diagnosed with HIV infection and 37% (17)
reported heterosexual transmission
HIV Infection 01/04/96 -
30/06/96
During the first six months of 1996
no infections in females were reported. Seven men have
been reported with HIV infection during the second
quarter of this year, and all reported male to male
sexual contact as their risk factor (Table 2.1). Between
01/01/96 and 30/06/96 six men (reporting male to male
sexual contact) had acquired their infection in the
preceding 12 months (Table
2.2)

HEPATITIS
C SURVEILLANCE IN SOUTH AUSTRALIA
Hepatitis C Medical Notification 1 April 1996 - 30 June
1996
Laboratories reported 530
individuals who tested positive for Hepatitis C infection
in the second quarter of 1996, 423 (80%) individuals were
notified by medical practitioners. Of the 423 medical
notifications received, 139 (32%) individuals reported
never having a test, 174 (41%) had previously tested
positive for Hepatitis C antibody, 19 (5%) individuals
reported a previous negative test result and information
on testing history was unavailable for 91 (22%)
individuals. Of the 19 individuals with a previous
negative test 6 were incident cases (defined by a
negative test or acute clinical illness in the preceding
12 months).
Of the 249 individuals who tested
positive for Hepatitis C infection for the first time in
1996, 157 individuals (63%) reported past and present
history of injecting drug use, 20 (8%) reported blood
transfusion/blood products as their only risk factor,
tattoos accounted for 2% (4) and unknown exposure
category accounted for 20% (50) of the infections
reported (Table 3.1).
A high proportion of individuals
were aged between 30 - 39 years (48% of men, 42% of
women) (Table 3.2).
Table
3.3 shows the reported race of individuals who tested
positive for hepatitis C infection for the first time in
1996.
There have been 6
individuals who acquired the infection in the preceding
12 months (defined by a negative hepatitis C antibody
test in the 12 months prior to diagnosis or diagnosed
acute illness) (Table 3.4).
None of the incident cases reported an acute illness
involving jaundice within the last 12 months.
During the second
quarter of 1996 there were 13,859 screening tests
performed, 6,763 (49%) on males, 7,008 (50%) on females
and 88 tests were performed on individuals whose sex was
not documented (Table 3.5).

HEPATITIS B SURVEILLANCE IN SOUTH
AUSTRALIA
Hepatitis B medical notification 01/04/96 - 30/06/96
During the second
quarter of 1996, 90 Hepatitis B medical notifications
were received. Of these, 6 were acute cases of Hepatitis
B infection (Tables 4.1,
4.2).
18 were carriers of
greater than twelve months duration who had been
previously diagnosed but not notified. There were 66
individuals who tested surface antigen positive for the
first time in this quarter.
Of the 66 individuals
who tested surface antigen positive for the first time
but were not acute cases, the racial origin of a high
proportion (46%) was reported as being Asian (Table 4.3).
Table 4.4 shows the
number of Hepatitis B surface antigen tests performed by
laboratories for this quarter.
