Via The Standard: Bird flu patient critical as doctor fails to spot disease.
A 61-year-old man remains in critical condition with H7N9 bird flu at Queen Mary Hospital, the third imported case this winter.
The Centre for Health Protection is investigating why a doctor did not immediately suspect flu, despite guidelines issued amid an outbreak in the mainland, which has seen 582 cases since March 2013.
According to the CHP, preliminary tests on the patient were positive for H7N9 and negative for H1 and H3 viruses.
The center has so far located 10 close contacts and 16 other contacts of the patient. They remained asymptomatic except for one who had mild cold symptoms before exposure to the patient.
A center spokesman said tracing of the health-care workers involved at Queen Mary Hospital is under way.
The man, with underlying illness, had suffered from a cough and shortness of breath since February 16 and consulted a private doctor on the same day.
He then attended the accident and emergency department of Queen Mary Hospital last Friday and was admitted.
His condition deteriorated and he was transferred to the intensive care unit. He was confirmed with H7N9 on Sunday.
The patient had traveled to Zhangmutou in Dongguan, Guangdong, on February 6-8 and again on February 14-15, where he visited a wet market and bought two chickens. He brought the birds back back to the city after they were cooked.
University of Hong Kong microbiologist Ho Pak-leung said the epidemic in the mainland seems to be moving south from Shanghai to Guangdong, closer to Hong Kong.
Ho warned that H7N9 bird flu could mix with seasonal flu virus H3N2, the strain behind current influenza cases in Hong Kong.
Meanwhile, nine additional cases of flu admission to intensive care units among adults aged 18 or above were reported, with two deaths.
This brings the total to 352 cases, of whom 254 have died.
