ObjectiveTo analyze the local
human immunodeficiency virus (
HIV)
infection characteristics and influencing factors of newly reported
HIV infected cases and
acquired immunodeficiency syndrome patients (
AIDS) in Ningbo City from 2017 to 2020, and to provide scientific basis for local effective
AIDS prevention and control
measures. MethodsFrom January 1, 2017 to December 31, 2020, the newly reported
HIV/
AIDS patients in Ningbo were recruited and
face-to-
face questionnaire was used to collect relevant information such as
demography,
behavior,
infection route and
infection location of
research subjects. The data were processed and analyzed by EpiData 3.1 and SPSS 23.0
software. ResultsA total of 449 newly reported
HIV/
AIDS patients were recruited and 399 cases completed the
survey. The
survey subjects were mainly
male (346, 86.7%),
unmarried (188, 47.1%),with local
household registration (246, 61.6%), with junior
high school and lower
education level (195, 48.9%), and 25 to 44 years old (206, 51.6%). The local
HIV/
AIDS infection rate was 68.4% (273/399), among which the local
HIV/
AIDS infection rate of
homosexual transmission was 74.9% (146/195).
Multivariate analysis showed that
heterosexual transmission of
HIV infection (OR=0.349,95%CI:0.201‒0.606), using dating
software to find local
sexual partners (OR=2.133,95%CI:0.201‒0.606), and received no
AIDS education services before
HIV confirmation (OR=1.914,95%CI:1.196‒3.063) were the influencing factors of local
HIV/
AIDS infection (P<0.05). ConclusionThe newly reported
HIV/
AIDS in Ningbo mainly infects
HIV locally, and the coverage of
HIV/
AIDS education is insufficient before
HIV confirmation. A high proportion of local
HIV/
AIDS infections is found in people
who find local
sexual partners through dating
software and
who infected through
homosexual transmission before
HIV confirmation. It is necessary to strengthen local
HIV/
AIDS education and
Internet intervention among MSM
who seek
sexual partners through dating
software.
