As short video platforms have become an important source of health information, evaluating the quality of HZ-related content is increasingly important.  \nMethods: This cross-sectional study analyzed 186 HZ-related videos collected from the Chinese short video platforms TikTok (n = 96) and Bilibili (n = 90) from 12 to 16 July 2025. Video characteristics (duration, likes, shares, comments, and collections), content domains (etiology, clinical manifestations, diagnosis, treatment, and prognosis), and uploader identity were recorded. Quality was evaluated using the Global Quality Score (GQS) and modified DISCERN (mDISCERN). Results: TikTok videos had shorter durations (47.5 vs.196.0 seconds) but significantly higher engagement metrics, including likes (481.5 vs. 29.5), comments (20.5 vs. 3.5), and shares (152.5 vs. 19.0). Most videos were uploaded by pain medicine specialists (31.72%), followed by traditional Chinese medicine physicians (27.96%) and dermatologists (19.35%). Treatment was the most frequently addressed topic (67.74%), whereas prognosis was least discussed (18.28%). The median GQS was 2.00 (interquartile range (IQR): 1.00–3.00) and the mDISCERN score was 3.00 (IQR 1.00–3.00). Dermatologists achieved higher GQS and mDISCERN scores than patients and traditional Chinese medicine physicians (p\u003C0.05). No significant correlations were observed between engagement metrics and GQS scores (p>0.05). Conclusions: HZ-related videos on short video platforms are of moderate quality and skewed toward treatment. Dermatologists involvement and better content regulation are needed. More emphasis should be placed on prognosis education to enhance public understanding.  \nKeywords  \nHZ, TikTok, Bilibili, health communication, video quality assessment  \nReceived: 17 July 2025; accepted: 16 December 2025  \nIntroduction  \nHerpes zoster (HZ) is caused by reactivation of latent varicella-zoster virus in sensory ganglia. 1,2 It primarily affects older adults and immunocompromised individuals, with typical manifestations including unilateral vesicular rash, dermatomal distribution, and neuropathic pain.3,4 Despite the availability of effective antiviral therapy and vaccines, the disease remains a significant public health concern, particularly due to complications such as postherpetic neuralgia (PHN), which severely impacts quality of life.5  \nIn recent years, short video platforms such as TikTok and Bilibili have become important sources of health information for the public, not only in China but also globally. Since its launch in September 2016, TikTok has rapidly  \nbecome one of the fastest-growing social media platforms worldwide.6 The platform allows users to create short videos that combine music, text, and effects, quickly becoming the most downloaded app globally in 2020, with a total of 850 million downloads.7 As of January 2024, TikTok has surpassed 1.62 billion users, with daily active users  \n1 Department of Dermatology, Xi’an Jiaotong University Second Affiliated Hospital, Xi’an, China  \n2Department of Dermatology, Xi’an Children’s Hospital, Xi’an, China  \nCorresponding author:  \nJiashu Liu, Department of Dermatology, Xi’an Children’s Hospital, Xi’an 710003, China.  \nEmail: dermatol_l[iu@163.com](iu@163.com)  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative Commons Attribution  \nNonCommercial 4.0 License ([https://creativecommons.o","cbCaiktLFsBKsAZb","https://ap.wps.com/l/cbCaiktLFsBKsAZb","pdf",1437069,11,"English","# Abstract\n## Objective\n## Methods\n## Results\n## Conclusions\n# Introduction","[{\"question\":\"How was the quality of herpes zoster information on TikTok and Bilibili evaluated?\",\"answer\":\"The study used the Global Quality Score (GQS) and modified DISCERN (mDISCERN) to assess video quality across recorded video characteristics and content domains.\"},{\"question\":\"What differences did the study find between TikTok and Bilibili videos?\",\"answer\":\"TikTok videos were shorter but had significantly higher engagement (likes, comments, and shares).
