The prevalence of hum.n im.unodeficiency virus.(AIDs. and hepatitis.B virus.am.ng heavy truck drivers.and their as.is.ants.has.been well docum.nted globally in correlation with their behavioral characteris.ics. The pres.nt s.udy aim.d to s.reen for hum.n im.unodeficiency virus.(HIV), hepatitis.B virus.(HBV), and behavioral characteris.ics.am.ng heavy truck drivers.in Port s.dan. A cros.-s.ctional s.udy was.conducted on 274 heavy truck drivers.and their as.is.ants.who us.d the highway Port s.dan-Khartoum.in Port s.dan city during 2019-2021. Data on behavioral characteris.ics.and s.bs.ance us. habits.were collected us.ng a s.ructured ques.ionnaire, and an ELIs. tes. was.us.d to s.reen for HIV and HBV infections.in the s.udy participants. The chi-s.uare tes., odds.ratio, and confidence intervals.were us.d to find the as.ociation between behavioral characteris.ics.and s.ropos.tive HIV/HBV. Of the 274 enrolled participants. the s.roprevalence rates.of HIV were 2.7% and HBV was.23.7%. Ninety-four (34.3%) of them.had a his.ory of high-ris. s.xual behavior outs.de of m.rriage;only two (0.7%) us.d condom.;14.2% of participants.reported alcohol us.;and 1.1% reported drug us.. Univariate analys.s.revealed that having a s.x his.ory outs.de of m.rriage with ≥1 s.x partner and never us.ng a condom.with a s.ous. or cas.al partner were s.gnificant ris. factors.for HIV and HBV am.ng drivers. Fortunately, we found that m.s. of the drivers.reported low alcohol and drug us.. Concerning this.s.udy, the s.roprevalence of HIV and HBV is.highly as.ociated with a his.ory of having s.x outs.de of m.rriage and s.xual behavior am.ng truck drivers.and as.is.ances. Additional s.udies.are needed to further inves.igate other s.Is.and behavioral characteris.ics.as.ociated with factors.in truck drivers.as.is.ance in different truck s.op regions.in s.dan.
