Communicable Disease Report 2003 - Chapter Two
- The declining incidence of measles is attributable to the implementation of the two-dose measles vaccine schedule in 1996.
- The incidence of mumps and rubella have also decreased since 1996 because mumps and rubella vaccines are routinely given a second time along with the measles vaccine (MMR - Measles/Mumps/Rubella conjugate vaccine).
- The incidence of pertussis has been low and stable since 1996 (approximately less than four cases per 100,000). Children under one year of age have the highest rate of pertussis.
- The incidence of influenza in the 2001/02 season was the highest in the last nine years. This is most likely due to greater reporting of cases by physicians.
- The reported incidence of influenza is highest in those aged less than 10 years and those greater than 60 years old. This may reflect the fact these are groups more likely to have a serious illness from influenza and be tested.
