Among the 210 positive samples, there were 141 cases of single infection, accounting for 67.14%, and 69 cases of multiple infection, accounting for 32.86%. After patients were grouped by ages, the highest positive ratio was 6/11 in the > 60 years old group, followed by the <20 years old group (37.50%, 15/40), 21-40 years old group (29.56%, 149/504) and 41-60 years old group (25.48%, 40/157) sequentially. And there were statistical differences among these groups in HIV positive rate (P<0.05). The positive rates in the third quarter and the fourth quarter were 35.20% (63/179) and 32.04% (58/181) respectively, which were significantly higher than the first quarter and the second quarter, of which the positive rates were 28.90% (50/173) and 21.79% (39/179) respectively (P<0.05).
