CHINA. The State Department issued a travel alert to U.S. citizens this week concerning China's quarantine measures in response to the 2009- H1N1 pandemic. Arriving passengers who exhibit fever or flu-like symptoms are being put into seven-day quarantine. Although the proportion of Americans being quarantined remains low, the random nature of the selection process increases the uncertainty surrounding travel to the country. Reports indicate passengers sitting in close proximity to another traveler exhibiting fever or flulike symptoms have been put into precautionary quarantine, as well as those arriving from areas where outbreaks have occurred (including the U.S. and Mexico) simply because they registered slightly elevated temperatures. All travelers to China, including U.S. citizens, must follow local procedures regarding quarantines; the U.S. Embassy is not able to influence the duration of stay in quarantine for affected travelers.
