  The COVID-19 outbreak in late 2019 represents the most significant public health emergency in a century in terms of transmission speed, scope of infection, and difficulty of containment. China, as the first country impacted by this crisis, demonstrated remarkable unity and decisive actions to successfully curb the epidemic's spread. The disclosure of confirmed case data served as both a foundational guideline for epidemic prevention and a crucial measure to evaluate containment effectiveness.

  Since late January 2020, Chinese authorities have maintained daily updates on COVID-19 confirmed cases with comprehensive granularity, reporting infection counts at the residential community level. This high-quality dataset—characterized by completeness, originality, timeliness, and continuity—provides detailed spatiotemporal insights into epidemic trends and containment progress, while offering valuable material for post-pandemic impact studies.

  The CnOpenData team presents the National Residential COVID-19 Confirmed Cases Database, containing detailed addresses, geographical coordinates (longitude/latitude), administrative divisions (province, city, district), confirmed case counts, and update timestamps.
