CHP notified of two human cases of avian influenza A(H7N9) on Mainland [      ]

The Centre for Health Protection (CHP) of the Department of Health (DH) today (December 11) was notified of two human cases of avian influenza A(H7N9) in Zhejiang and Guangdong by the National Health and Family Planning Commission (NHFPC), and again urged the public to maintain strict personal, food and environmental hygiene both locally and during travel.

According to the NHFPC, the cases comprise a male farmer aged 60 in Hangzhou, Zhejiang, and a male farmer aged 74 in Meizhou, Guangdong. They had poultry exposure history and are currently in serious condition.

“Based on previous seasonal patterns, it is likely that the activity of avian influenza viruses will increase in winter. Heightened vigilance is warranted. Locally, we will work closely with the World Health Organization and relevant health authorities to monitor the latest developments,” a spokesman for the DH said.

So far, six cases have been reported by the NHFPC since October 2015 (five in Zhejiang and one in Guangdong).

From 2013 to date, 663 human cases of avian influenza A(H7N9) have been reported by the Mainland health authorities.

The DH’s Port Health Office conducts health surveillance measures at all boundary control points. Thermal imaging systems are in place for body temperature checks on inbound travellers. Suspected cases will be immediately referred to public hospitals for follow-up.

The display of posters and broadcast of health messages in departure and arrival halls as health education for travellers is under way. The travel industry and other stakeholders are regularly updated on the latest information.

Travellers, especially those returning from avian influenza-affected areas with fever or respiratory symptoms, should 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.

The public should remain vigilant and take heed of the 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); and 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.

Abstract

OBJECTIVES:

Stringent measures have been implemented in Hong Kong to prevent human infections due to avian influenza viruses (AIVs). Here, we report the seroprevalence of AIVs among high risk population.

METHODS:

In this prospective study, blood samples were collected in October and November 2013 and in July 2014 from workers at live poultry market (LPM) and pig/cattle slaughterhouse (SH) in Hong Kong. Serum antibody titers against A(H5N1), A(H7N9) and A(H9N2) were determined.

RESULTS:

When an hemagglutination inhibition (HI) titer of 40 was used as the cutoff, the A(H5N1) seropositive rate among LPM workers increased from 0% in 2013 to 37.8% in 2014 (P<0.001) and the A(H9N2) seropositive rate increased from 10% to 55.6% (P<0.001). There was no significant increase in A(H7N9) seropositive rate for LPM workers irrespective of cutoff titer. For SH workers, there was no significant increase in HI titer for any AIVs. Significantly more LPM workers had a ≥4-fold increase in A(H5N1) HI titer from 2013 to 2014 than SH workers (60% vs 8.3%, P=0.020).

CONCLUSIONS:

There was a significant increase of serum A(H5N1) and A(H9N2) HI titers among Hong Kong LPM workers between 2013 and 2014, suggesting the occurrence of subclinical AIV infections in this population.

#HK, Secretary for #Food and #Health on #monitoring of #avian #influenza (Govt., Nov. 25 ‘15)

[Source: Government of Hong Kong PRC SAR, full page: (LINK).]

SFH on monitoring of avian influenza [      ][      ]

Following is the transcript of remarks made by the Secretary for Food and Health, Dr Ko Wing-man, after attending a public function today (November 25):

Reporter: (About stepping up the monitoring measures for avian influenza.)

Secretary for Food and Health:

With the arrival of winter and the drop of ambient temperature, it is expected that the activities of both seasonal influenza as well as avian influenza will increase. Therefore, we will correspondingly step up our measures in monitoring both the carcasses of birds found as well as our local live poultry farms.

Reporter: There is no plan to lift the ban on the importation of chickens from the Mainland?

Secretary for Food and Health:

I need to clarify that there is currently no ban on poultry imported from the Mainland. It is mainly because in the past winter season, we had a positive result in examining one of the batches of imported poultry. Following that, we closed the wholesale market for 21 days. The Mainland authority also correspondingly enhanced their control measures, leading to a decrease in the live poultry supply from the Mainland.

(Please also refer to the Chinese portion of the transcript.)
