Central Myanmar- the significant role in regional FMD control

• FMD outbreak hotspots (dark orange)(2011-2014: O/SEA/Myanmar-98)

• Significant socio-economic burden - USD 5-20 per drought cattle- USD 81 per infected cow

• PCP progression requirement

FMD Vaccination Project

February and March 2015:

• 18 townships in Central Myanmar

• 1127 villages vaccinated

• Benefiting >54,000 owners

• >210,000 large ruminants vaccinated 2x

FMD Vaccination Project

Parallel FMD education campaign:

• FMD recognition and reporting

• Biosecurity

• Outbreak responses

• Cleaning and disinfection

• Benefits of vaccination

O/Mya-98A/SEA-97

• FMD was reported in 226 villages in 2015

• 75% outbreaks occurred during Aug-Oct (after flooding)

• Outbreaks in close proximity to major rivers/roads

• (re)emergence of new strains (A/SEA-97, O/Ind2001)

14 out of 226 outbreaks occurred in vaccinated villages (n=1127):

• waned immunity (>5 months after the last vaccination)

• serotype A virus

• antigenically variant viruses

• vaccination coverage

• vaccination failure

The majority of vaccinated villages were clinically protected against FMD

Expanded Vaccination Campaign

• Additional 5 rounds of vaccinations implemented since 2016

• Expanded to another 6 townships

• Updated vaccine composition:+ A/Malaysia/97 and A22/Iraq in 2016 + Asia 1/Shamir in 2017/18

• Vaccination coverage

• Public awareness campaign

• Animal identification and tracing

• VAHW capacity building

• Biosecurity

• Outbreak response

Trade opportunities stimulate FMD Control

220,000

365,000

74,000

• >1 million large ruminants from SEA enter China annually

• Significant costs associated with unofficial movements (500 USD/head in Myanmar)

• 3 pilot trade zones to be established between China-Myanmar/Laos borders

• Vaccinate-to-move: reduce risks along movement pathways

• Challenges:- steady supply of high-quality vaccines- increase buy-in from farmers & traders- infrastructure- monitoring

Proposed trade zones and estimated annual trade volumes
