Update on measles cases
     The Centre for Health Protection (CHP) of the Department of Health (DH) is today (April 17) investigating a case of measles infection.

     As at 4pm today, one case, which involves a 45-year-old woman, was recorded. The woman with good past health developed fever since April 12 and rash since April 15. She consulted a general practitioner on April 13 and attended the Accident and Emergency Department at Pok Oi Hospital on April 15 and was transferred to Tuen Mun Hospital for admission and treatment on the same day. A laboratory test of her respiratory specimen was positive for the measles virus. She has been in a stable condition. She has reported to have measles vaccination, and had travelled to Taipei during the incubation period and to Jiangmen, Guangdong, during the communicable period.

     According to the patient, she did not have contact with measles patients during the incubation period. The home contacts of the patient have remained asymptomatic so far and have been put under medical surveillance.

     Upon notification of the case, the CHP immediately commenced epidemiological investigations and conducted relevant contact tracing. Investigations are ongoing. The public place the patient visited during the communicable period is listed in the appendix.

     "The incubation period (the period from infection to appearance of illness) of measles ranges from seven days to 21 days. Symptoms of measles include fever, skin rash, cough, runny nose and red eyes. If symptoms arise, members of the public should wear surgical masks, stop going to work or school and avoid going to crowded places. They should also avoid contact with non-immune persons, especially persons with weakened immunity, pregnant women and children aged below 1. Those suspected to have been infected are advised to seek medical attention as early as possible and reveal relevant contact history of measles to healthcare professionals," a spokesman for the DH advised.

     Regarding measles control measures implemented at Hong Kong International Airport (HKIA), a total of 20 persons received measles vaccination at the airport vaccination station as at 6pm today, bringing the cumulative number of vaccinations given to 8 206.
