  • Avian Influenza

    When avian influenza hits will science have an efficient vaccine?

  • Origin Of Avian InfluenzaAvian Influenza also know as Bird Flu is an infectious disease caused by type A H5N1 Strain of influenza virus. This virus is transmissible from fowl to human or human to humanThe most abundant outbreaks are in the more Central Northern region of Asia

  • Origin Of Avian InfluenzaAvian Influenza also know as Bird Flu is an infectious disease caused by type A H5N1 Strain of influenza virus. This virus is transmissible from human to fowl or human to humanThe most abundant outbreaks are in the more Central Northern region of Asia

  • The Bird Flu Strain After virus transfers into a new host either avian or mammalian, influenza viruses undergo rapid evolution

  • SpreadIt is easy to spread bird flu in the Central region of Asia because of the day to day contact with people and fowls83% of the H5N1 host were from backyard chickens and ducksSome of the birds that are infected are migratory

  • PreventionIn order to prevent spread of the virus people have tried to eliminate infected poultry.At the cost of 10 billion dollars 140 million chickens and ducks have been slaughtered

  • Prevention cont.Most people also have a since of awareness and are more educated.The percentage of adults who though that picking up or touching sick or dead poultry was safe decreased from 40% to 14%70% of people say that they wear gloves or a protective mask when dealing with fowl.

  • Vaccine ProblemsThese preventions are not as efficient as a vaccination. Vaccines are currently being made available for the avian influenza, but it is made for present day flu strains which will mutate eventually. Then a new vaccine will have to be made

  • Can not make enough We still depend on eggs to make our flu vaccines 900 million doses of vaccine can be produced every 6 monthsBecause this virus is new to our body we will need 2 dosesWay around this is to add a strong boost of a chemical called adjuvantBut not enough research has been developed to know how much dosage a person would have to take

  • DistributionAvian Influenza companies have not worked out how they are going to distribute the vaccineToo many big orders from different countries manufactures do not know what country to give the vaccination to firstSome orders may never be fulfilled because the vaccine is in such demand

  • Distribution cont.Rich countries will have much less scarcity than the poor countries70% of the worlds manufacturing capacity is in five countries in Western EuropeThese countries might be reluctant to share with out making sure that their country first has an adequate amount

  • Will Scientist be able to find an efficient vaccine?If no efficient vaccine is made experts say that when the virus strain changes that there will be 25 million hospital admissions and up to 7 million global deaths will happen

  • ConclusionBird Flu is a serious virus and should not be overlookedThe virus will spread fastDespite all of the efforts we make to prevent avian influenza if there is no efficient vaccine made than millions will die
