摘要：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 belowthe number reported in the outbreak years of 1993 and 1994. Rubella notifications furtherdecreased and remained low in 1998. The Measles Control Campaign from August to November1998, 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 in1991, and appeared to have stabilised at a low rate since the introduction of the conjugated vaccin ein 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 innotification 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 sexuallytransmitted diseases and third highest for all notifiable diseases. Notifications of gonococcalinfection also continued to rise and have doubled since 1991, whilst notifications for syphilisincreased slightly after falling steadily over recent years. Arbovirus infections of concern in 199 8were dengue outbreaks in Far North Queensland and the first case of Japanese Encephalitis formainland Australia, highlighting the importance of surveillance of arboviruses and vectors fortheir detection and management
