Since January 2020, Elsevier has established a COVID-19 resource center on its public news and information website, Elsevier Connect, providing free English and Mandarin information about the novel coronavirus. Elsevier has granted permission to make all COVID-19-related research available in PubMed Central and other public repositories, with unrestricted reuse and analysis rights, as long as the resource center remains active. During the COVID-19 outbreak in China, the National Health Commission published several guidelines to address psychological issues among medical staff and the public, including anxiety, depression, and stress. The widespread availability of internet services and smartphones, along with 5G networks, enabled the provision of online mental health services. These services include online surveys, mental health education through social media platforms, and free 24/7 psychological counseling services. A survey of medical staff found high prevalence rates of depression, anxiety, insomnia, and stress-related symptoms. Online psychological self-help systems and AI programs, such as Tree Holes Rescue, have also been utilized to support individuals at risk of suicide. These online mental health services are facilitating the development of emergency interventions and improving their quality and effectiveness.Since January 2020, Elsevier has established a COVID-19 resource center on its public news and information website, Elsevier Connect, providing free English and Mandarin information about the novel coronavirus.
