Most common viral skin infections are not reportable conditions. Studying the population dynamics of these viral epidemics using traditional field methods is costly and time-consuming, especially over wide geographical areas.
This study aimed to explore the evolution, seasonality, and distribution of vaccinable and nonvaccinable viral skin infections through an analysis of Google Trends.
Worldwide search trends from January 2004 through May 2021 for viral skin infections were extracted from Google Trends, quantified, and analyzed.
Time series decomposition showed that the total search term volume for warts; zoster; roseola; measles; hand, foot, and mouth disease (HFMD); varicella; and rubella increased worldwide over the study period, whereas the interest for Pityriasis rosea and herpes simplex decreased. Internet searches for HFMD, varicella, and measles exhibited the highest seasonal patterns. The interest for measles and rubella was more pronounced in African countries, whereas the interest for HFMD and roseola was more pronounced in East Asia.
Harnessing data generated by web searches may increase the efficacy of traditional surveillance systems and strengthens the suspicion that the incidence of some vaccinable viral skin infections such as varicella, measles, and rubella may be globally increasing, whereas the incidence of common nonvaccinable skin infections remains stable.
大多数常见的病毒性皮肤感染并非须上报的疾病。使用传统实地方法研究这些病毒流行的人群动态既费钱又耗时，尤其是在广阔的地理区域。
本研究旨在通过分析谷歌趋势来探索可接种疫苗和不可接种疫苗的病毒性皮肤感染的演变、季节性和分布情况。
从谷歌趋势中提取并量化分析了2004年1月至2021年5月全球范围内病毒性皮肤感染的搜索趋势。
时间序列分解显示，在研究期间，全球范围内疣、带状疱疹、幼儿急疹、麻疹、手足口病（HFMD）、水痘和风疹的搜索词总量增加，而玫瑰糠疹和单纯疱疹的关注度下降。对HFMD、水痘和麻疹的网络搜索呈现出最高的季节性模式。非洲国家对麻疹和风疹的关注度更高，而东亚地区对HFMD和幼儿急疹的关注度更高。
利用网络搜索产生的数据可能会提高传统监测系统的效能，并强化这样一种怀疑，即一些可接种疫苗的病毒性皮肤感染，如水痘、麻疹和风疹的发病率可能在全球范围内上升，而常见的不可接种疫苗的皮肤感染发病率保持稳定。
