Spatio-temporal analysis of human immunodeficiency virus in MIMAROPA and Eastern Visayas (2010-2018)

Human Immunodeficiency Virus (HIV), a virus that targets the immune system of an infected individual, continues to spread in some countries in Asia and the Pacific despite the global decline of the infection. In the Philippines, the virus continues to spread among ages 25 to 34, males and females, in Region 4B and Region 8. Using the relative risk, the global Moran\u27s I values are computed and analyzed to study the presence of spatial autocorrelation. The expected values of the global Moran\u27s I in each region are then used to identify the presence of positive and negative spatial autocorrelation. In Region 4B, there is a presence of negative spatial autocorrelation in 2015 and 2016 and positive spatial autocorrelation in Region 8 during 2012 and 2015. Provinces with relatively high or low local association are identified using the local Moran\u27s I. Results showed that Palawan has clusters with high rates and is surrounded by clusters with low rates for Region 4B. In Region 8, Leyte was found to have clusters with high rates surrounded by clusters with low rates. The occurrence of HIV generally increased from 2010 to 2018
