They were found at the Cochin airport around midnight and isolated at the hospital, Alappuzha district collector M Anjana said. The taxi driver, on Saturday, reported at the medical college hospital for tests.The US nationals had reached Kochi from London — where they have been living for the past three years — via Doha on March 9. They visited Fort Kochi before leaving for Alappuzha the next day, and later left for Varkala in Thiruvananthapuram . They sought medical help when the woman complained of uneasiness.
