"Travellers, especially those returning from avian influenza A(H7N9)-affected areas and provinces, with fever or respiratory symptoms are reminded to immediately wear facial masks, seek medical attention and reveal their travel history to doctors. Health-care professionals should also pay special attention to patients who might have had contact with birds, poultry or their droppings in affected areas and provinces," the spokesman said.
