The woman came down with malaria as the result of being bitten by a malaria-infected mosquito at the airport. The mosquito might have entered the airport on the suitcase of a traveler who had been on an international flight from a country that had a malaria risk. It could also have been in a jetliner. As international travel has increased, there has been an increase in the incidence of “airport malaria” in the United States and in Europe. Cases have been reported for people who live and work close to international airports, as well as for people visiting an airport.

STUDY SKILLS Leading a group Scenario These are the things Ahmed is doing well; making a list of questions to talk about prior to the discussion, helping start the discussion by sharing his own ideas, asking others for their ideas, noticing that a classmate isn’t participating, and bringing that person into the discussion, telling a classmate who has interrupted to let the other classmate finish first, and reviewing ideas they’ve shared at the end of the discussion. These are the things he is doing wrong: not setting clear goals for the discussion at the beginning, not asking someone in the group to take notes in order to keep track of the ideas discussed, talking about his own ideas for a long time rather than briefly presenting them to launch the discussion, and letting all the group members talk at the same time so that they don’t listen to one another.
