Avian Influenza and Tajikistan

FAO Emergency Coordination Unit Tajikistan


Avian influenza in tajikistan l.jpg

Avian Influenza in Tajikistan

  • Background

  • Risks of Avian Influenza introduction in Tajikistan

  • Mitigating risks of introducing and spreading Avian Influenza virus

  • Risks of Avian Influenza to humans from poultry products in Tajikistan

  • Measures taken by FAO and SVD

Background 1 l.jpg

Background (1)

  • Various species of animals have their “own” strain of influenza virus, including birds and humans

  • Some strains are able to infect several species, but can normally not spread between individuals of these “foreign” species

  • Avian influenza viruses have historically on several occasions mutated and acquired the ability of human-human spread

  • Such viruses caused three major influenza pandemics during the last century, in 1918 (Spanish flu), 1957 (Asian flu) and 1968 (Hong Kong flu).

Background 2 l.jpg

Background (2)

  • The H5N1 AI virus have been circulating in poultry since at least 1996

  • Initially infectivity not very high, causing limited disease

  • For last 3 years, found in wild migratory birds

  • N. & SE Asia & Indonesia - wild birds started epidemic, spread through live-bird market chain

Next steps in tajikistan preparedness l.jpg

Next steps in Tajikistan - Preparedness

  • Evaluate the potential transmission paths -wild migratory birdscontact points wild migratory birds – domestic poultry cross border live bird importssmuggled live birdslive bird markets

  • Targeted surveillance at high risk points

  • Diagnosis of suspect AI cases

  • Send AI virus isolates to international reference labs for gene characterization

Next steps in tajikistan prevention l.jpg

Next steps in Tajikistan - Prevention

  • Enhance biosecurity in commercial & small-holder poultry farms

  • Separate wild migratory birds from domestic poultry

  • Enforce hygiene in live bird markets –separate areas for different bird speciesdo not return unsold live birds to farmsclean & dry cages, floors, counters, etc

  • Raiseawareness for reporting deaths or disease in poultry & wild birds to SVD

  • SVD write & practice Standard Operating Procedures for AI disease investigation

Next steps in tajikistan reaction l.jpg

Next steps in Tajikistan - Reaction

  • Control outbreak zones by:halting movement of poultrylimiting movement of people, good hygienequarantine domestic birds within gardensstamp out infected & in-contact poultrypay compensation for destroyed poultryclean & depopulate infected zone - 60 dayslive bird markets – closed temporarilyor close 1 day per week for cleaning

  • Consider vaccinating poultry at risk

FAO Emergency Coordination Unit Tajikistan


Summary of control strategies l.jpg

Summary of Control Strategies

  • Control by stamping out works in countries with small outbreaks + high surveillance

  • Vaccination enhances success of control & potentially reduces risk to humans

  • Need targeted surveillance based on expected transmission pathways in Tajikistan

  • Manage risks in each production system –smallholder poultrycommercial poultrydomestic poultry

Risks of avian influenza to humans from poultry products in tajikistan l.jpg

Risks of Avian Influenza to humans from poultry products in Tajikistan

  • Consuming poultry meat and eggs frozen meat & clean egg shells = no risknormal cooked meat & eggs = no risk

  • Handling or preparing poultry products

    fresh poultry meat = wash hands, knives & counters with soap and hot waterfeathers, poultry house dust = low riskpoultry manure dust = low risk

  • Buying live poultry in markets aerosols in markets = low risk

High risk activities to avoid l.jpg

High Risk Activities to Avoid

  • Higher risk when AI has been diagnosed in the area -

    not the case for Tajikistan!

  • Direct contact with AI infected birds

    - attending cock fights

    - buying from crowded, live bird markets

    - drinking blood from birds

Measures taken by fao and svd 1 l.jpg

Measures taken by FAO and SVD (1)

Actions targeting veterinarians:

  • One national seminar and a serious of regional workshops on Transboundary Animal Diseases (TAD)

  • Training courses on bird diseases

  • Training course on virology for laboratory veterinarians

  • FAO and SVD staff attending workshop in Pakistan on Participatory Diseases Surveillance (PDS)

  • PDS carried out in RRD, planned for Sugd

  • Next edition of National Veterinary Magazine totally devoted to TAD, including article on how to recognize, and handle, cases of AI

Measures taken by fao and svd 2 l.jpg

Measures taken by FAO and SVD (2)

Actions for informing the public of AI:

  • One TV programme

  • One radio programme

  • Printing of 4000 posters ongoing

FAO Emergency Coordination Unit Tajikistan


Summary l.jpg

Summary

  • No AI reported in Tajikistan as yetSVD preparedness and targeted surveillance could be enhanced

  • Low risk of poultry in Tajikistan getting AIlow concentrations of poultryimportant to separate wild migratory birds from domestics

  • Low risk of humans in Tajikistan getting AIwell cooked and clean products are safecan avoid high risk activities

  • Strengthening SVD and veterinarians surveillance & diagnostic capacity helps protect the publicAI is priority today, other diseases tomorrow
