What is added by this report? The overall rates of new diagnosis of HIV/AIDS per 100,000 populations increased 3.26 and 2.18 times among male and female in all ages from 2007 to 2018, respectively. Among adults aged ≥60 years, the rate increased 10.41 times (1.35 to 14.06 per 100,000) from 2007 to 2018. Male adults aged 60–69 and 70–79 years and female aged 50–59 and 60–69 years had the highest increasing rates among all groups. What are the implications for public health practice? This study highlights the need to strengthen HIV/AIDS prevention among older adults. Health education and other effective measurements might be used to prevent HIV/AIDS among this group.
