Many government websites and mobile content are inaccessible for people with vision, hearing, and cognitive disabilities. The COVID-19 pandemic highlighted these disparities when health authority website information, critical in providing resources for curbing the spread of the virus, remained inaccessible for disabled populations. The Web Content Accessibility Guidelines provide comparatively universally accepted guidelines for website accessibility. We utilized these parameters to examine the number of countries with or without accessible health authority websites. The resulting data indicate a dearth of countries with websites accessible for persons with disabilities. Methods of information dissemination must take into consideration individuals with disabilities, particularly in times of global health crises.

COVID-19上的一课，关于全世界残疾人无法获取基于网络的信息

有视力，听力和认知障碍的人无法访问许多政府网站和移动内容。当卫生当局的网站信息对于为控制病毒的传播提供遏制至关重要的信息仍然使残疾人无法访问时，COVID-19大流行突出了这些差距。Web内容可访问性指南提供了相对通用的网站可访问性指南。我们利用这些参数来检查有无健康权威网站的国家数量。结果数据表明，缺乏残疾人可用网站的国家。信息传播方法必须考虑到残疾人，尤其是在全球健康危机时期。
