摘要：Aim: To examine trends in the inci-dence of typhoid fever in NSW to inform thedevelopment of prevention strategies. Methods:Typhoid fever case notification data for the period2005–2011 were extracted from the NSW Notifi-able Conditions Information Management System.Population incidence rates were calculated andanalysed by demographic variables.Results: Therewere 250 case notifications of typhoid fever inNSW from 2005 to 2011, of which 240 are likelyto have been acquired overseas. Case notificationsremained relatively stable over the review periodwith the highest rates in Western Sydney LocalHealth District(10.9per 100 000population). Two-thirds (66.4%) of all case notifications are likely tohave been acquired in South Asia, and about half ofoverseas-acquired case notifications were mostlikely to have been associated with travel to visitfriends and relatives. Hospitalisation was requiredfor 79.6% of cases where hospitalisation status wasknown. Prior typhoid vaccination was reported in7% of cases in 2010 and 2011 where vaccinationstatus was known. Conclusion: While typhoidfever rates remain low in NSW, case notifica-tions of this preventable infection continue to bereported, particularly in travellers visiting friendsand relatives in South Asia. Further research tobetter understand barriers to the use of preventivemeasures may be useful in targeting typhoid feverprevention messages in high-risk groups, particu-larly South Asian communities in NSW
