Four Czechs at heightened risk from "super TB"

The Czech health authorities are trying to trace four Czechs who took a flight from Prague to Montreal on CSA flight 0104 on May 24th. The four are in a high risk group of passengers who sat close to a US citizen infected with "super TB", a strain of tuberculosis which is extremely hard to treat. The man was placed in isolation on arrival in Montreal. There were 187 passengers on the plane, but only those sitting in the same row with the ill man, one in front and one behind are considered to be most at risk.
