A woman in Toronto has become the first person in Canada this century to have
caught malaria without travelling abroad. Kevin Kain, director of the tropical
diseases unit at Toronto General Hospital, says that the woman was bitten by a
mosquito that had already fed on an infected person who had returned to Canada
after contracting the disease in the tropics. Kain rules out other
possibilities, such as a mosquito that had hitched a ride on a plane. 鈥淧eople in
temperate countries shouldn鈥檛 get complacent,鈥� he warns.
