• Contributes 55.1% to the agriculture value added • Share in National GDP is 11.5% with 3.7% growth rate in 2010-11 • Share in Total Foreign Exchange Earnings is more than 8.5% • Nearly 8 million families involved with 30-35% income dependent on
livestock production activities • Value of livestock & its products is more than the combined value of
major and minor agricultural crops. • Provides raw material to Leather Industry, Carpet industry, Soap
industry, Pharmaceutical industry, etc.

compared with buffaloes.
– Clinical signs/severity of the disease are less pronounced in buffaloes than cattle
– Serotypes independent of species

Asia-1
Two genetic groups existed • New Group (VII) identified recently
• Group II & VI covered with Shamir but not with Ind8/79 • Recent Group II viruses not neutralized with Shamir • Group VII isolates not neutralized by existing vaccine strains
Strain A/IRN/05
• Strain A/IRN/05 detected for the first time in Pakistan (in 2006).
• The strain was found responsible for sub-clinical infection in Asian buffalos while it caused clinical disease in cattle
• The strain has undergone two different paths of
evolution in the structural and non-structural genome regions.
– The structural genome regions might have had their
evolutionary starting point in strain A22, with A/IRN/96 and A/IRN/99 as evolutionary intermediates
FMD Virus Circulation
• Detection of new variant of FMDV type O shows that
this virus is evolving and is present at least in Pakistan and Afghanistan.
• At least two sub-lineages of serotype A (IRN05AFG-07 and IRN05BAR-08) are presently in circulation in Pakistan and Afghanistan.
• At least two different genotypes of Asia1 virus are in circulation in the area (Group I in Pakistan and Group II in Afghanistan).
FMD Control in Pakistan
• National and International Support to control TADs – Build capacity for FMD Diagnostics and Epidemiological investigations
under GCP/Pak/088/EC and GTFS/INT/907/ITA.
• Surveillance & Reporting system – Monthly reports from each district cover FMD Outbreaks – Flash Reporting in case of active outbreak
• Vaccination – Voluntary vaccination – Local vaccine production: Trivalent, Stationery cell culture, not
purified – Imported vaccines: (Merial, ARRIAH, Intervet, Czech Republic, Others)
Progressive Control of FMD in Pakistan
• FMD Conference held in Islamabad on 16-17 February 2010 identified FMD as the priority livestock disease for control and recommended formulation of FMD control project
• Government of Pakistan signed a project with FAO on
progressive control of FMD in Pakistan with ID as GCP/PAK/123/USA
• Program outlays 3 major outputs and 16 activities addressing
improved capacity of diagnostics and surveillance, response to outbreaks and effective vaccination strategy
GCP/Pak/123/USA - Project Outputs • Output 1: Capacity to diagnose FMD at disease,
serotype and genotype level enhanced at districts, provincial and reference laboratories in Pakistan
• Output 2: Surveillance of and response to FMD outbreaks in the country improved
• Output 3: Benefits of early and consistent immunization practices demonstrated for effective control of FMD
Progressive Control of FMD in Pakistan
Output 1: Capacity to diagnose FMD at disease, serotype and genotype level enhanced in districts, provincial and reference laboratories in Pakistan
Activities
1. Strengthening of Laboratory capacity for FMD diagnosis
2. Capacity building of field and laboratory staff
3. Proficiency testing of diagnostic labs
4. Development of an harmonized (central and provincial) Laboratory Information and Management System (LIMS)
Output 2: Surveillance of and response to FMD outbreaks in the country improved
Activities 1. Awareness of livestock farmers 2. Capacity building of field staff and policy makers 3. Outbreak reporting, epidemiological investigation and submission of samples 4. Sero-monitoring for determining the level of virus circulation different farming systems 5. Creation of a rapid response mechanism for FMD outbreaks 6. Creation of a National FMD Epidemiology and Information System 7. Strengthening of FMD monitoring program in Landhi Dairy Colony Karachi
Output 3: Benefits of early and consistent immunization practices demonstrated for effective control of FMD
Activities 1. Identification of appropriate vaccine for field use 2. Strengthening NVL capacity for evaluation of FMD vaccines 3. Effective vaccination in dairy colony production system 4. Early immunization in market oriented rural dairy production system 5. Evaluation of FMD vaccination effects on productivity in different dairy production systems
Expectations from FMD Control Initiatives in Pakistan
• Current initiative under GCP/PAK/123/USA is expected to provide framework within which progressive control of FMD will be continued and implemented
• Initiative will help to move Pakistan to higher stages (stage 2 3) of the Progressive Control Pathway
