15. Explanatory Notes
Non-identifiable HIV data were extracted from the computerised infectious disease reporting system (CIDR) on 12th March 2019, and were correct at the time of publication. It is important to note that - the HIV surveillance system captures new diagnoses of HIV infection and therefore does not measure incidence. - persons newly diagnosed in Ireland may have been previously diagnosed with HIV in another country and are included in surveillance figures at first confirmatory test in Ireland. - Data are analysed by date of notification on CIDR
The counties covered by each HSE area are as follows: HSE East (HSE E): Dublin, Kildare & Wicklow; HSE Midlands (HSE M): Laois, Longford, Offaly & Westmeath; HSE Midwest (HSE MW): Clare, Limerick & Tipperary North; HSE Northeast (HSE NE): Cavan, Louth, Meath & Monaghan; HSE Northwest (HSE NW): Donegal, Leitrim & Sligo; HSE South (HSE S): Kerry & Cork; HSE Southeast (HSE SE): Carlow, Kilkenny, Tipperary South, Waterford & Wexford; HSE West (HSE W): Galway, Mayo & Roscommon.
