According to the World Health Organization, two employees at the Chinese Institute of Virology in Beijing contracted the SARS coronavirus in April 2004 independently, while studying the virus. The lab workers then spread the disease to seven others, resulting in one fatality.

The Beijing facility had been studying active and inactive variations of the SARS virus, and WHO noted "concern" over the incident, which occurred a year after the 2003 SARS outbreak. No known transmission of the SARS virus has occurred since 2004.

This Fact Brief is responsive to conversations such as this one.
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Lab. Over the course of these two years, Gigafact Lab writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Lab reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
