| Description |
| The
Hong Kong Centre for Health Protection (CHP) of the Department of
Health (DH) is investigating an imported human case of avian influenza
A(H7N9) affecting a woman aged 85. The patient, with underlying medical
conditions, traveled to Dongguan from April 4 to 5 with her husband and
younger brother. They lived at their relatives’ home where their
relatives have reared chickens. The patient also visited a wet market
near their home there and helped in slaughtering chickens at home on
April 4. She returned to Hong Kong on April 5, and developed fever,
cough with blood-stained sputum and shortness of breath since April 11.
She was sent to the Accident and Emergency Department of Tseung Kwan O
Hospital (TKOH) by ambulance today and was subsequently admitted. She is
currently managed under isolation and her condition is critical. Her
respiratory specimen was positive for avian influenza A(H7N9) virus upon
preliminary laboratory testing by the CHP’s Public Health Laboratory
Services Branch today. This is the 10th imported human H7N9 avian flu
case to date. Initial investigation revealed that the patient had
visited her husband at Haven of Hope Hospital (HHH) on April 10 who was
admitted due to other illness. Her husband has remained asymptomatic so
far and is currently under observation at HHH. Apart from her husband,
seven other family members of the patient are also considered as close
contacts. One of them had sore throat since April 12 and his condition
is stable. The other close contacts have remained asymptomatic so far.
These close contacts will be admitted to hospital for observation and
their respiratory specimens will be taken for preliminary laboratory
testing. The CHP’s investigations and tracing of other contacts are
ongoing. The patient’s brother who traveled to Dongguan with the
patient, relevant healthcare workers, ambulance staff and patients who
had stayed in the same cubicle with the patient’s husband at HHH are
being traced for exposure assessment and medical surveillance. |
| Biohazard name: | H7N9 - Highly pathogenic avian influenza virus |
| Biohazard level: | 4/4 Hazardous |
| Biohazard desc.: | Viruses
and bacteria that cause severe to fatal disease in humans, and for
which vaccines or other treatments are not available, such as Bolivian
and Argentine hemorrhagic fevers, H5N1(bird flu), Dengue hemorrhagic
fever, Marburg virus, Ebola virus, hantaviruses, Lassa fever,
Crimean-Congo hemorrhagic fever, and other hemorrhagic or unidentified
diseases. When dealing with biological hazards at this level the use of a
Hazmat suit and a self-contained oxygen supply is mandatory. The
entrance and exit of a Level Four biolab will contain multiple showers, a
vacuum room, an ultraviolet light room, autonomous detection system,
and other safety precautions designed to destroy all traces of the
biohazard. Multiple airlocks are employed and are electronically secured
to prevent both doors opening at the same time. All air and water
service going to and coming from a Biosafety Level 4 (P4) lab will
undergo similar decontamination procedures to eliminate the possibility
of an accidental release. |

Imported human case of avian influenza A(H7N9) under CHP investigation
*********************************************************
The
Centre for Health Protection (CHP) of the Department of Health (DH) is
today (April 9) investigating an imported human case of avian influenza
A(H7N9) affecting a woman aged 82.The patient, with underlying
medical conditions, lives in Liwan, Guangzhou with her family. She has
presented with cough with blood-stained sputum since April 7 but had no
fever.
She came to Hong Kong with her two family members by car
via Lok Ma Chau Spur Line Control Point yesterday (April 8). Upon
arrival, she was directly transferred to the Accident and Emergency
Department of North District Hospital by ambulance and was admitted for
further management under isolation on the same day. Her current
condition is stable.
Her sputum specimen was tested positive for
avian influenza A(H7N9) virus upon preliminary laboratory testing by the
CHP's Public Health Laboratory Services Branch tonight.
The patient has been transferred to Princess Margaret Hospital for isolation and treatment.
Her exposure history to poultry is under investigation.
The
CHP's investigations and contact tracing are ongoing. The patient's
family members in Hong Kong, relevant healthcare workers, ambulance
staff and immigration officer at Lok Ma Chau Spur Line Control Point are
being traced for exposure assessment and medical surveillance.
"The
Serious Response Level under the Government's Preparedness Plan for
Influenza Pandemic remains activated and the CHP's follow-up actions are
in full swing," a spokesman for the CHP remarked.
This is the
ninth confirmed human case of avian influenza A(H7N9) in Hong Kong. The
CHP will notify the World Health Organization (WHO), the National Health
and Family Planning Commission as well as health and quarantine
authorities of Guangdong and Macau.
Locally, enhanced surveillance
of suspected cases in public and private hospitals is underway. The CHP
will continue to maintain liaison with the WHO, the Mainland and
overseas health authorities to monitor the latest developments. Local
surveillance activities will be modified upon the WHO's recommendations.
"In
view of human cases of avian influenza A(H7N9) confirmed locally and in
the Mainland, further cases are expected in affected and possibly
neighbouring areas. Those planning to travel outside Hong Kong should
maintain good personal, environmental and food hygiene at all times,"
the spokesman urged.
"All boundary control points have implemented
disease prevention and control measures. Thermal imaging systems are in
place for body temperature checks of inbound travellers. Random
temperature checks by handheld devices have also been arranged.
Suspected cases will be immediately referred to public hospitals for
follow-up investigation," the spokesman added.
Regarding health
education for travellers, display of posters in departure and arrival
halls, in-flight public announcements, environmental health inspection
and provision of regular updates to the travel industry via meetings and
correspondence are proceeding.
The spokesman advised travellers,
especially those returning from avian influenza-affected areas and
provinces with fever or respiratory symptoms, to immediately wear masks,
seek medical attention and reveal their travel history to doctors.
Healthcare professionals should pay special attention to patients who
might have had contact with poultry, birds or their droppings in
affected areas and provinces.
"We have enhanced publicity and
health education to reinforce health advice on the prevention of avian
influenza," the spokesman said.
As of 4pm today, the CHP's hotline
(2125 1111) for public enquiries has received 217 calls since the first
confirmed human case of avian influenza A(H7N9) in Hong Kong.
Members of the public should remain vigilant and take heed of the preventive advice against avian influenza below:
*
Do not visit live poultry markets and farms. Avoid contact with
poultry, birds and their droppings. If contact has been made, thoroughly
wash hands with soap;
* Avoid entering areas where poultry may be
slaughtered and contact with surfaces which might be contaminated by
droppings of poultry or other animals;
* Poultry and eggs should be thoroughly cooked before eating;
* Wash hands frequently with soap, especially before touching the
mouth, nose or eyes, handling food or eating; after going to the toilet
or touching public installations or equipment (including escalator
handrails, elevator control panels and door knobs); or when hands are
dirtied by respiratory secretions after coughing or sneezing;
* Cover the nose and mouth while sneezing or coughing, hold the spit with a tissue and put it into a covered dustbin;
* Avoid crowded places and contact with fever patients; and
* Wear masks when respiratory symptoms develop or when taking care of fever patients.
