Emerging disease surveillance and response

Overview of Emerging Disease Surveillance and Response

The Emerging Disease Surveillance and Response (ESR) unit works with Member States and partners in the Western Pacific Region to build sustainable national and regional systems and capacities to ensure public health security through preparedness planning, prevention, early detection and rapid response to emerging infectious diseases, including epidemic-prone diseases.


All member states have established notified disease surveillance systems. WHO is receiving data on notifiable diseases on a regular basis. Data is stored in a database and analyzed at Western Pacific Regional Office. To disseminate this information, the first issue of Western Pacific Regional Office Communicable Diseases Bulletin was published in November 1999. Electronic data entry system using Internet is now under being tested to facilitate quick reporting and feedback.

Outbreak response

WHO has provided support to the Member States in outbreak situations, which include: dispatch of experts in response to government requests; providing supplies and equipment; providing information on diseases and disease control measures; coordination of international investigation teams; and dissemination of information during outbreaks to the Member States and the public.

Marking ASEAN Dengue Day

Manila, Philippines, 13 June 2013 — The World Health Organization (WHO) Western Pacific Region and the Association of Southeast Asian Nations (ASEAN) call on the public and private sectors to join forces in the fight against dengue.

As the Region commemorates ASEAN Dengue Day on 15 June, many countries in Asia and the Pacific face an increasing burden from the disease, with more cases reported in 2013 compared to the same period in 2012. Moreover, the recent trend continues to increase sharply in the Lao People’s Democratic Republic and Singapore, and most of the dengue endemic ASEAN countries are just entering the dengue season, with the peak still coming.
