Measles has been eliminated in NSW for more than a decade; however outbreaks associated with international travel do occur. This EpiReview describes the epidemiology of measles in NSW from [2002][2003][2004][2005][2006][2007][2008][2009][2010][2011]. A total of 281 cases of measles were notified during the period, an average annual notification rate of 0.41 notifications per 100 000 population (range: 0.06-1.25). There were 139 hospitalisations recorded with a measles diagnosis in the 10-year reporting period, corresponding to a rate of 0.20 hospitalisations per 100 000 population. Of the 80 measles virus specimens genotyped, five genotypes were identified: D9 (38%), D8 (24%), D4 (16%), D5 (14%) with H1 identified less frequently (9%). No single genotype was associated with local transmission across successive years. To sustain good measles control, children should be vaccinated against measles on time through routine childhood immunisation, and all young adults who travel internationally should be vaccinated. Clinician awareness remains important in the early identification and control of measles to avoid further transmission during outbreaks and to enable the timely implementation of public health measures.Measles is an acute and highly contagious viral disease that is currently the most important cause of vaccinepreventable death globally. 1 Measles is rare in Australia with low rates of hospitalisation and death. 2 Measles is transmitted by airborne particles, droplets or fomites and humans are the only host of the measles virus. Common symptoms of measles include fever, rash, cough, coryza, conjunctivitis, diarrhoea and loss of appetite. Complications include ear infections, pneumonia, convulsions, croup, encephalitis and death. A milder illness is sometimes seen in vaccinated individuals, 3 and severe disease tends to occur in infants and malnourished persons. 1 Sub-acute sclerosing panencephalitis is a rare, delayed, fatal complication of measles virus infection.In Australia, measles-mumps-rubella (MMR) vaccines are scheduled as two doses for all children: the first at 12 months and the second at 4 years of age. 4 In 2013, the inclusion of measles-mumps-rubella-varicella vaccine (MMR-V) on the childhood immunisation schedule will bring forward the second measles dose to 18 months from 4 years. 5 In addition, documented immunity to measles has been a mandatory requirement for new health care workers in New South Wales (NSW) since 2007. In NSW, the percentage of children immunised with at least one dose of MMR at 2 years of age is 93.9%, 6 with some variation across local health districts (LHDs) and Aboriginal communities. 7 People at highest risk of measles infection include: infants aged less than 1 year (who are too young to be vaccinated); children aged 1-4 years who have received only a single dose of vaccine, especially if received late; and those born in the late 1960s to mid 1980s (who were neither infected with measles, nor vaccinated against it). 8Multiple lines of evidence suggest measl...
