1. Current diagnostic algorithms are not sensitive enough to detect TB patients early;
2. TB concentrates among high-risk and socially vulnerable populations who are difficult to reach;
3. Multi-drug resistant TB: only a small fraction of MDR-TB patients are diagnosed, ensuring treatment is also a challenge;
4. High percentage of external funding, esp through the Global Fund. Donor investment is shrinking in the Region, which threatens sustainability of programmes.

Tuberculosis: Financial Gap WPR
In the WPR, national TB programmes report a funding gap of over USD 200 million per year.

HIV: Challenges in Financing HIV programmes
Heavily reliant on donor funding for low and middle income countries, particularly Cambodia (89%), Lao PDR (93%) and Viet Nam (83%). Government should increase their domestic public HIV spending as GDP per capita rises;
Not enough is spent on key populations prevention programmes, e.g. spending on prevention for key populations accounts for only 24% of AIDS spending in Asia and the Pacific (2009-2012).
Moreover, prevention spending on key populations is heavily dependent on international financing sources.

Hepatitis: Gaps and Challenges
• Low levels of awareness, advocacy, and financial engagement from national governments
• Lack of data is a barrier to country-level dialogue and engagement
• Progress made in prevention, especially HBV immunization, but high coverage of birth dose vaccination remains a challenge in many countries
• Remarkable advances in hepatitis treatment options, but equitable access to quality and affordable diagnostics and medicines still far for many countries.

Measles: Disease Burden and Trends Measles Cases by Month and Year, WPR, 2008–2013
Progress towards 2012 Measles Elimination Goal:94% reduction in reported measles cases in the Region between 2000 and 2012 when historic low incidence was achieved;
A relative resurgence in measles occurred in the Region in 2013 and 2014 with recent outbreaks in China, Papua New Guinea, the Philippines, and Viet Nam.
15
Measles: Strategies and ChallengesReported measles cases and coverage with first and
second dose of measles vaccine, 1980-2012 An important strategy to achieve measles elimination is high (>95%) coverage with two doses of measles vaccine.
Immunity gaps (pockets of susceptible persons, especially among migrants) allows measles virus to continue spreading
4 (of 37) countries and areas have not yet introduced routine second dose:•Lao People’s Democratic Republic •Papua New Guinea•Solomon Islands•Vanuatu

EID: Avian Influenza A(H5N1) – Human Cases
Since 2013, the Western Pacific Region accounted for over 80% of
all H5N1 human cases
• Cambodia: – Overall 56 cases (37 deaths, CFR
66%). – In 2014, 9 cases reported.
• China:– Overall 47 cases (30 deaths, CFR 64%)– In 2014, 2 cases reported.
• Lao PDR:– Overall 2 cases ( 2 deaths) were reported in 2007– Since then, no case has been reported to date
• Viet Nam:– Overall 127 cases ( 64 deaths, CFR 50%) – In 2014, two fatal cases reported

EID: International Health Regulations 2005
• Legally binding international instrument for global public health security, for preventing international spread of disease, enforced 2007
• International commitment for shared responsibilities and collective defence against diseases information sharing!
• Network of national IHR focal points and WHO contact points, 24/7
28
EID: Challenges
• Health security threats continue to occur in unexpected way, if not managed well, resulting in significant health, economic, social and political consequences
• Strong national and international capacities are a MUST for managing unpredictable/uncertain threats
• The Region is NOT sufficiently prepared to cope with severe public health emergencies and disasters
• Investing in health security essential, AND sustaining it equally vital
29
EID: The way forward
• Continue to support to countries in meeting the IHR core capacity requirements through implementation of the Asia Pacific Strategy for Emerging Diseases/APSED (2010). This includes capacity building in surveillance, laboratory, zoonoses, risk communication, PH emergency planning
• Regional strategies, especially APSED, have proven to be valuable tools to support countries to meet IHR core capacity requirements.
• Promote cross-cutting capacities that serve as foundation for all emergency risk management
• Foster regional partnerships for emergency risk management • Respond to major emerging disease outbreaks and
emergencies swiftly and in coordinated way (WHO Emergency Response Framework)

Malaria: Threats & Opportunities
THREATSLosing the gains and investments made, malaria resurgence
o Shrinking financingo Limited/declining programme capacityo Decreasing government commitment once cases decreaseo Unregulated economic development
Artemisinin resistanceo Health systems issues, e.g pharmaceutical issues (OAMTs,
counterfeit/substand medicines, stockouts, irrational drug use)o Malaria control and elimination services, eg insufficient reach to migrant/mobile
populationso Insufficient engagement of the non-health sector

Malaria: The Global Challenge of Artemisinin Resistance
• Foci identified in five countries in the Greater Mekong Subregion, mainly along international borders
• Artemisinin resistance so far only confirmed in this region
• Containment efforts ongoing since 2008
• Number of detected foci increasing
35
Malaria: Emergency Response Framework
• Emergency response based on strategic recommendations of a joint assessment by development partners
• Aim is to increase coordination, quality and coverage of interventions
• Launched in 2013 in Phnom Penh, Cambodia, where WHO has opened a Regional Hub to coordinate ERAR (supported by the Gates Foundation and Australia)
• Global Fund has committed 100 million USD to combat artemisinin resistance in GMS
• Funding gap was estimated at USD 450 mio/3 years, but will be higher due to recent TEG recommendation to expand Tier 2 throughout GMS

Conclusions
• Major improvements have been achieved across a range of communicable diseases in the Region, but the CD burden remains significant, disproportionately affecting the poor. Much remains to be done.
• We have effective tools for most diseases. These cannot be sufficiently rolled out, largely because of significant funding gaps, which are increasing due to shrinking external funding to the Region. Despite most of the countries in the Region having moved to middle-income status, these funding gaps currently cannot all be shouldered by national budgets, except in a few.
• Malaria is especially vulnerable to losing the enormous gains and investments made, as it can resurge rapidly once interventions are scaled back prematurely.
• There are many opportunities for regional collaboration (e.g ERAR, ASEAN, IHR/APSED, Interpol) which should be intensified.
42
Priorities for a regional response
1. Mobilize funds to fill the programme gaps. o Prioritize high incidence countries. o Artemisinin resistance containment/elimination, as a regional and global
public good, should receive international financingo Malaria elimination should have significant domestic funds.
2. Use the opportunity of the current revision and costing of National Malaria Strategic Plans in most countries to get detailed analyses of malaria programme requirements (eg commodities, funds), which should be used at regional and global levels.
3. Foster greater collaboration between malaria and other national and regional initiatives, for synergies and cost saving, and document and evaluate this. Including on cross cutting issues such as migrant health.
4. Initiate innovative funding models and pilot and evaluate them. o
