Assessment of the Level of Knowledge and Attitude Towards Herpes Zoster and Its Vaccination Among Individuals at Risk...

Background Herpes zoster (HZ) is a viral infection resulting from the reactivation of the varicella-zoster virus. The vaccination was proven to prevent herpes zoster and its complications for individuals over the age of 50 since they are more susceptible to herpes zoster infection. Therefore, it is essential to understand and acknowledge the herpes zoster infection and vaccine. This study aims to assess the level of knowledge and attitude towards herpes zoster and its vaccination among individuals at risk in Saudi Arabia. Methods A cross-sectional study was conducted between February 2023 and June 2023 among the general population in Saudi Arabia, using a self-administered online questionnaire adapted from a previous study after translating it into Arabic. Results A total of 1883 participants were included in this study, almost equally distributed across the five regions of Saudi Arabia. Females represented 62.4% (n=1175), and 56% (n=1062) of participants reported a positive history of chickenpox, while 3.6% (n=67) reported a history of herpes zoster. Furthermore, 78.9% (n=1486) have heard of herpes zoster, while 68.8% (n=1296) have at least one of the herpes zoster risk factors. Only 7.8% (n=147) had high knowledge about HZ, and only 3.1% (n=58) had adequate knowledge regarding the HZ vaccine. Conclusion Our study findings show that the general population of Saudi Arabia has inadequate knowledge about herpes zoster and its vaccine. For that reason, awareness and education programs targeting individuals at high risk of herpes zoster are required to enhance awareness and knowledge about herpes zoster and to improve their attitudes toward the herpes zoster vaccination.
