In 1998 there were 85,096 notifications to the National Notifiable Diseases Surveillance System; slightly lower than in 1997 (89,579). The number of measles cases remained low, and well below the number reported in the outbreak years of 1993 and 1994. Rubella notifications further decreased and remained low in 1998. The Measles Control Campaign from August to November 1998, did not impact significantly on the number of measles or rubella cases reported for 1998. Notifications of Haemophilus influenzae type b reached a record low since surveillance began in 1991, and appeared to have stabilised at a low rate since the introduction of the conjugated vaccine in 1992. The previously reported outbreak of pertussis in 1997 tapered off in early 1998. Food-borne disease, or detection of disease, appeared to be on the rise with an increase in notification rates of campylobacteriosis and salmonellosis. Notifications of hepatitis A decreased, correcting the previous high number of notifications in 1997. Sexually transmissible diseases (STDs) increased. Notifications for chlamydial infection were the highest for all sexually transmitted diseases and third highest for all notifiable diseases. Notifications of gonococcal infection also continued to rise and have doubled since 1991, whilst notifications for syphilis increased slightly after falling steadily over recent years. Arbovirus infections of concern in 1998 were dengue outbreaks in Far North Queensland and the first case of Japanese Encephalitis for mainland Australia, highlighting the importance of surveillance of arboviruses and vectors for their detection and management.

Development of resistance to antibiotics is a major problem worldwide. The normal oropharyngeal flora, the intestinal flora and the skin flora play important roles in this development. Within a few days after the onset of antibiotic therapy, resistant Escherichia coli, Haemophilus influenzae and Staphylococcus epidermidis can be detected in the normal flora of volunteers or patients. Horizontal spread of the resistance genes to other species, e.g. SALMONELLA: spp., Staphylococcus aureus and Streptococcus pneumoniae, occurs by conjugation or transformation. An ecologically sound antibiotic policy favours the use of antibiotics with little or no impact on the normal flora. Prodrug antibiotics which are not active against the bacteria in the mouth and the intestine (before absorption) and which are not excreted to a significant degree via the intestine, saliva or skin are therefore preferred. Prodrugs such as pivampicillin, bacampicillin, pivmecillinam and cefuroxime axetil are favourable from an ecological point of view. Experience from Scandinavia supports this, since resistance to mecillinam after 20 years of use is low (about 5%) and stable.

Trimethoprim-sulfamethoxazole (TMP-SMZ) is widely prescribed as prophylaxis for Pneumocystis carinii pneumonia (PCP) in human immunodeficiency virus (HIV)-infected persons. Its efficacy against other infections has not been thoroughly evaluated. To compare the risk for infectious diseases for persons who were prescribed TMP-SMZ with that for patients who were not prescribed TMP-SMZ, we examined data collected from the medical records of HIV-infected patients (January 1990 through September 1999) who were enrolled in the Adult and Adolescent Spectrum of HIV Disease Project. During intervals when patients had CD4(+) T lymphocyte counts of <200 cells/microL (19,081 persons; 22,801 person-years), prescription of TMP-SMZ was associated with significant protection from toxoplasmosis, salmonellosis, infection with Haemophilus species, invasive or any staphylococcal infection, and PCP, but not from Shigella, pneumococcal or nonpneumococcal Streptococcus, Klebsiella, or Pseudomonas species. We demonstrate that prescription of TMP-SMZ for PCP prophylaxis in persons with HIV infection is associated with significantly decreased risk for several infectious diseases. These findings may be of interest to HIV prevention programs in resource-poor countries.
