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. The 2019-nCoV outbreak, originating in Wuhan, China, has rapidly spread to multiple countries, causing acute infectious pneumonia. As of February 4, 2020, over 24,000 confirmed cases and 490 deaths were reported in mainland China, with significant numbers in Hubei province. The virus has also been detected in Southeast Asia, East Asia, South Asia, Western Asia, Europe, North America, and Australia. Approximately 13% of infected individuals have severe respiratory symptoms, 2% have died, and 4% have recovered. Human-to-human transmission is occurring, and WHO recommends measures to limit its spread. The outbreak has caused public panic and mental health stress, exacerbated by misinformation and travel bans. Healthcare workers, who are exposed to trauma and at risk of infection, face significant challenges and stress, which can lead to mental disorders. The Chinese government has implemented comprehensive public health emergency responses, including level 1 responses in all 31 provincial-level regions. Psychological crisis intervention is included in these responses, with guidelines released by the National Health Commission. Peking University is preparing a mental health handbook and offering psychological counseling services through various platforms. Including mental health care in the national public health emergency system is crucial for empowering China and the world in the fight against 2019-nCoV.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.
