CDC Museum Timeline Chronicles Origins and Early Spread of COVID-19
The CDC Museum offers a detailed timeline documenting the initial emergence of the novel coronavirus in late 2019 and the global health response in early 2020. The museum remains temporarily closed and requires advanced reservations for future visits.
The David J. Sencer CDC Museum presents a comprehensive timeline that tracks the COVID-19 pandemic from its known origins to the present day. While the physical museum remains temporarily closed to the public, this online resource serves as a vital record of how the novel coronavirus emerges and spreads globally.
The timeline begins in late 2019, noting that patients in Wuhan, China, experience an atypical pneumonia that does not respond to standard treatments. By December 31, the World Health Organization learns of these pneumonia cases of unknown cause, which all appear connected to the Huanan Seafood Wholesale Market.
As early 2020 arrives, Chinese authorities close the implicated seafood market and the WHO activates its incident management teams. The CDC quickly establishes its own response structure, though the complete genetic sequence of the virus remains unavailable to the rest of the world as the outbreak continues to develop.
