The Hong Kong Centre for Health Protection (CHP) of the Department of Health (DH) reported today the investigation into the third imported human case of avian influenza A(H7N9) infection in Hong Kong this year affecting an 80-year-old man.
This is the 16th imported case into Hong Kong since 2013.
The patient, with underlying illnesses, traveled to Dongguan, Guangdong from April 1 to 5. He has presented with cough with sputum, headache and gouty attack since April 6 and consulted a private doctor on April 7. He sought medical consultation from another private doctor on April 14 and was found to have fever. He developed confusion and refused eating on April 17, and was sent to Accident and Emergency Department of United Christian Hospital by ambulance for treatment on the same day. He was subsequently admitted to isolation ward.
The patient’s sputum specimens tested positive for avian influenza A(H7N9) virus upon laboratory testing by the Public Health Laboratory Services Branch of the CHP. The patient will be transferred to the Hospital Authority Infectious Disease Centre in Princess Margaret Hospital for further management. He is currently in stable condition.
Initial investigations by the CHP revealed that the patient visited a wet market near his residence in Dongguan on April 2. He bought a live chicken from the wet market and slaughtered it on April 3. His two travel collaterals and another three close contacts have remained asymptomatic so far. Tracing of the patient’s contacts in Hong Kong is ongoing.
The CHP’s investigation is continuing.
