Results:

83.313 AIDS cases were recorded in the state; during the periods 1980-1990, 1991-2000 and 2001-2015, the detection rates in the state were 1.1, 17.2 and 40.3/100,000 inhab., respectively, and in the MRPA the detection rates were 2.4, 33.6 and 66.9/100,000 inhabitants, while mortality rates were 0.5, 8.5 and 12.6/100,000 inhab. in the state, and 1.3, 17.3 and 21.7/100,000 inhab. in the MRPA; in 2001-2015, the detection rate of HIV+ pregnant women per 1.000 live births in the state was 8.1 and 13.7 in the MRPA, while injecting drug users in the state (8.2%) and in the MRPA (8.9%) also stood out.
