The applicant in this matter is a medical practitioner. On 7 December 2001, while working in a clinic run by Cathay Pacific Airways for the benefit of its staff, the applicant was consulted by Ms Chinen Akiko, an air hostess. The applicant prescribed treatment for what he at the time diagnosed to be a respiratory infection. During the consultation no questions were asked concerning Ms Akiko’s recent travel history. In fact, some two weeks earlier Ms Akiko had been in South Africa and had taken a trip to a game park where she had been bitten by a mosquito.
