TI  - Seasonality in testing and positive respiratory bacterial infections in the 
      Australian Capital Territory, 1997-2007.

AB  - BACKGROUND: Chlamydia pneumoniae (Cp) and Mycoplasma pneumoniae (Myco) bacteria 
      are atypical pathogens that can cause pneumonia and exacerbate underlying 
      conditions such as asthma and chronic obstructive pulmonary disease. In the 
      Australian Capital Territory, there is limited information on how seasonal 
      patterns for positive infections and testing may vary, a gap that has 
      implications for control strategies. METHODS: We examined seasonal patterns of 
      immunoassay results of patients from Canberra Hospital, Australia, who were 
      tested for Cp and/or Myco. Pathology data, collected from August 1997 to March 
      2007 from 7,275 patients, were analysed with time series additive decomposition 
      and time series regression. RESULTS: The proportion of positive Cp infections was 
      highest in March and April (autumn) and lowest in June and August (winter). The 
      proportion of positive Myco infections was highest in December and January 
      (summer) and lowest in August (winter), even though testing for the pathogen 
      peaked in winter with a low in summer. Models with a long-term trend and a 
      variable for month were a better fit for the data than the null models for both 
      infections. CONCLUSION: We found differences in seasonal patterns of testing and 
      in the proportion of positive infections. These findings suggest that 
      preventative measures for common infections need to account for seasonal testing 
      practices so as to build an accurate picture of temporal changes in these 
      infections.
