RESUMO
INTRODUCTION: Herpes simplex virus type 1 (HSV-1) is one of the most common human viral infections and has a double-stranded DNA genome belonging to the Herpesviridae family. Smoking is one of the leading causes of disease and premature death worldwide, responsible for the death of up to six million people annually. The purpose of the current study was to determine the seroprevalence of HSV-1 infection among smokers. Methods. The search strategy was conducted in the period from December 2022 to January 2023. The study included a random sample of 94 (88 males, and 6 females) healthy participants, aged between ≤ 20 to ≥ 60 years, with 50 participants as the control group. The HSV serological testing consisted of detecting antibodies to HSV-1 IgG with the help of ELISA. RESULTS: Most participants were university students, consisting of 45.7% males and 5.3% females, followed by employed smokers, consisting of 0.2% males and 1.1% females. The number of females was much lower than that of males reaching 6.4 and 93.6% respectively, due to customs and traditions. The seroprevalence was 24.47, 22.3 and 2.1% in males and females respectively. The seroprevalence rate was 13.8% in hookah and cigarette smokers, 9% in cigarette smokers and 1.1% in hookah smokers exclusively. The highest rate was observed in the age groups of 21-30 and 31-40 years with 12.80% and 7.40% respectively. CONCLUSIONS: The study revealed that the seroprevalence of HSV-1 IgG was 24.47%, and was higher among hookah and cigarette smokers compared to those who exclusively smoked cigarettes or hookah.
