Abstract
The onset of autumn brought with it further declines in pertussis and salmonellosis notifications (Figure 1, Table 2). Hepatitis A, rubella and measles have all remained uncommon in recent months. Autumn tends to be the peak season for legionnaires disease, but so far in 2001, no particular peak has emerged in notifications. However, it is timely to remind building owners of the importance of ensuring that cooling towers are regularly inspected and cleaned, to minimise the risk of contamination with legionella bacteria.
