Abstract We reported several personal-oriented and mobile phone-based information technologies which were recently developed and widely used during the outbreak of COVID-19 in China. These technologies help reduce the transmission of COVID-19 and maintain normal social order. Keywords Coronavirus . Information technology . Prevention To Editor Information technology has been widely used by medical professionals in the hospitals and the centers of disease control for the prevention and control of infectious disease, which includes timely reporting, epidemic surveillance, and monitoring of programmed immunization. In addition, web-based surveillance tools and epidemic intelligence methods, used by public health institutions, are intended to facilitate risk assessment and timely outbreak detection. However, information technology is poorly developed for use by general people, although they are actually the susceptible subjects of infection and the infectious source as well. The outbreak of coronavirus disease 2019 (COVID19), a disease stemming from SARS-COV-2, began in the year 2019 December in Wuhan, China.

the lives of general people. During this period, several personal-oriented and mobile phone-based information technologies are developed and widely used in China, which helps reduce the transmission of COVID-19 and maintain normal social order. The application of health status code first launched on 11th Feb in Hangzhou city, Zhejiang, China. Based on big data and mobile internet technologies, residents and those entering the city need to apply online and receive either a green, red, or yellow code. The colors are based on the information reported by the applicants, including their state of health, travel history, and whether they contacted people from epidemic areas. People with green code may travel around the city. Those with red or yellow codes must first undergo 7 to 14 days of quarantine. According to the classification, the government restricts the travel of people with potential infection but allow healthy people to travel freely and resume work. Based o
