Containment[edit]
The World Health Organization declared severe acute respiratory syndrome contained on 9 July 2003. In the year after, SARS made the occasional appearance. There were four cases spotted in China in December 2003 and January 2004. As well, three separate laboratory accidents resulted in infections; in one case, an ill lab worker spread the virus to several other people.[3][29] The precise coronavirus that caused SARS is gone or mostly contained within different BSL-4 laboratories for research much like Smallpox, but different coronaviruses remain circulating in the wild, like MERS, the Common Cold and gastroenteritis.
