THE 3rd MEETING OF NATIONAL INFLUENZA CENTRES IN THE WESTERN PACIFIC AND SOUTH EAST ASIA REGIONS

18 - 20 AUGUST 2009, BEIJING, CHINA


The 1st NIC meeting of WPR and SEAR

• The 1st NIC meeting of WPR and SEAR was hosted by WHO CC in Melbourne, Australia on 1 – 4 May 2007– 45 participants (Public Health Officials and NIC

directors) from 19 countries in the two regions– Identified the gap, the need, and the way forward– A workplan for establishing/strengthening a

comprehensive National Influenza Surveillance System was developed

WER, 2007; 82 (45): 389-400; http://www.who.int/wer


The Gap

• Great contribution of influenza viruses to the Global Influenza Surveillance Network without understanding of influenza disease in most of the developing countries in the region


The Need

• Not only contribute the virus

• But also understand the disease

• Provide essential information for the development of national control policy

• Contribute to national pandemic preparedness


The Way Forward: Workplan for Building Capacity for A Comprehensive

National Influenza Surveillance System (NISS)

Goals of the Workplan by 2010:• to develop and sustain comprehensive

National Influenza Surveillance Systems through enhancing / strengthening the capacities of the National Influenza Centers and associated epidemiology programmes

• to have preliminary understanding of influenza disease burden in countries in Asia Pacific


Building Capacity For Comprehensive National Influenza Surveillance Systems (NISS):

Workplan and Expected Outcomes by 2010

1. Improving virological testing capacity in the National Influenza Centres

2. Better understanding the epidemiology of influenza through link of virological and epidemiological surveillance for influenza

3. Improving the early warning function of national influenza surveillance

4. Contributing to the national rapid response and containment and pandemic preparedness


The WPRO Guidelines

• “A Practical Guide to Harmonizing Virological and Epidemiological Influenza Surveillance”

• “A Practical Guide for Designing and Conducting Influenza Disease Burden Studies”

The 2nd Bi-regional NIC meeting

• The 2nd bi-regional NIC meeting of WPR and SEAR was hosted by WHO CC in NIID, Tokyo, Japan on 21 – 24 April 2008– 59 participants (Public Health Officials, NIC

directors, and epidemiologists) from 21 countries in WPR and SEAR

– The meeting reviewed and commented the two guidelines and the NIC laboratory database software and outlined the next steps

SECTION 2: Event-Based Surveillance as Early Warning System

• Introduction• Event Definitions• Minimum Requirements• Reporting Sources• Reporting methods• Minimum Information from Reporting• Confirmation and Assessment• Routine Feedback• Monitoring and Evaluation


Surveillance for Pandemic Influenza:Outcome of the regional workshop on WHO revised

pandemic influenza preparedness guidance 3-6 March 2009, Fukuoka, Japan

• A well established comprehensive national influenza surveillance system is the key to success for pandemic influenza surveillance

• The National pandemic preparedness process should facilitate strengthening or establishing the comprehensive national influenza surveillance system

Public health interventions

• Prepare for rational public health actions, especially implementation options of nonpharmaceutical interventions based on assessed situations and country context. Advance planning is the key to smooth implementation.

• Implement individual and household public health measures, including hand and respiratory hygiene, to protect individuals from infection.

• Implement societal measures such as social distancing when necessary, to slow down or reduce transmission at population level.
