The Health Protection Agency, in collaboration with the National Public Health Service for Wales (NPHSW), is reviewing the number of cases of toxoplasmosis diagnosed by the Toxoplasma Reference Unit (TRU) in Swansea . This follows the recent publication addressing the epidemiology of congenital toxoplasmosis [1].

A total of 667 cases were diagnosed by TRU over a recent 12 month period (July 2005 to June 2006), compared with an average of 117 cases reported annually to the HPA by NHS laboratories [2]. This would suggest that the decrease in the incidence of toxoplasmosis in the UK during the mid-1990s may have been due to changes in reporting arrangements. Comparison of numbers of reference unit reports between the early 1990s and the present provides no evidence to support a significant reduction over this period.

More detailed analysis of the data provided by TRU reveals that 185 of the 667 cases identified were in patients either classed as known HIV positive, or considered to be at high risk for HIV infection (based upon indication by the referring laboratory). Further analysis will follow in subsequent reports in CDR Weekly.
