Nearly 200 Americans evacuated from China because of the new virus are "very relieved' to be quarantined at a military base in Southern California for two weeks, one of them said Friday.

China, with 5,974 cases of a new virus, has more infections than it did in with SARS, though the death toll is still lower. China had 5,327 cases of SARS in the 2002-2003 outbreak.
