SARS UPDATE: If you assume that the authorities always either overreact or underreact to these things, then we’d better hope they’re overreacting:

An American Airlines flight from Tokyo has been quarantined on the tarmac at San Jose’s airport after four people on board complained of symptoms like those reported from the mysterious new illness spreading through Asia, airline and city health officials said.

Two passengers and two crew members complained of symptoms similar to those found in Severe Acute Respiratory Syndrome, according to city health officials.

Flight 128 from Tokyo to Mineta San Jose International Airport was stopped on the tarmac short of the gate, and ambulances lined up near the plane as the 125 passengers and 14 crew members waited on board.

That’s how I’m betting for now. Hope I’m right.
