4 The total number of persons estimated to be living with HIV disease is based on the Centers for Disease Control calculation and is the number of persons known to be living with HIV disease (5,760) divided by 0.86. The difference between this calculation (6,698) and 5,760 is the additional number of persons living with HIV disease but are estimated to be unaware of their diagnosis (938). 5 The number of PLWHD living in 2014 is based on the actual number living at the end of the year. Prior to 2014, an estimate was used based on how many of the 5,760 PLWHD were living at the end of each of the previous years. The numbers shown for 2005-2013 may include people who were not living in Orange County at that time and may exclude people who were living in Orange County during 2005-2013 who were not living here at the end of 2014.
