Abstract The COVID-19 epidemic has swept across China and spread to other countries. The rapid spreading of COVID-19 and panic combined with the lack of a hierarchical medical system in China have resulted in a huge number of hospital visiting which are overwhelming local medical system and increasing the incidence of cross infection. To meliorate this situation, we adopted the management concept of the system of Tiered Diagnosis and Treatment and developed an online tool for self-triage based on the mostly used multi-purpose smartphone app Wechat in China. This online tool helps people perform self-triage so that they can decide whether to quarantine at home or visit hospital. This tool further provides instructions for home quarantine and help patients make an appointment online if hospital visiting suggested. This smartphone application can reduce the burden on hospitals without losing the truly COVID-19 patients and protect people from the danger of cross infection.

Background The disease COVID-19 caused by the novel coronavirus SARS‐CoV‐2 (previously 2019-nCoV) has been spreading rapidly since the initial discovery in December of 2019. As of 24:00 on February 15, more than 70,000 confirmed cases have been reported in China [1]. In comparison to SARS and MERS, COVID-19 is characterized by several unique characteristics, such as strong virulence, longer Juan Yu, Han-wen Zhang, and Yuan-kai Shao contributed equally to this work.

incubation period, and insensitivity to nucleic acid detection. Although many mild patients do not show severe symptoms at early stage of infection, they will soon start the inflammatory storm leading to multiple organ failure [2]. These characteristics of COVID-19 and our lack of counteractive measurements, coupled with the huge number of passenger journeys during the Chinese New Year period, have led to the rapid spreading of the disease which is exhausting local medical resources. All of these factors have brought great challenges to the prevention and control of the COVID-19 epidemic. According to Professor Zhong, a top Chinese expert
