Avian Influenza When avian influenza hits will science have an efficient vaccine?
Origin Of Avian Influenza • Avian 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 human • The most abundant outbreaks are in the more Central Northern region of Asia
Origin Of Avian Influenza • Avian 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 human • The 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
Spread • It is easy to spread bird flu in the Central region of Asia because of the day to day contact with people and fowls • 83% of the H5N1 host were from backyard chickens and ducks • Some of the birds that are infected are migratory
Prevention • In 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 Problems • These 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 months • Because this virus is new to our body we will need 2 doses • Way around this is to add a strong boost of a chemical called adjuvant • But not enough research has been developed to know how much dosage a person would have to take
Distribution • Avian Influenza companies have not worked out how they are going to distribute the vaccine • Too many big orders from different countries • manufactures do not know what country to give the vaccination to first • Some orders may never be fulfilled because the vaccine is in such demand
Distribution cont. • Rich countries will have much less scarcity than the poor countries • 70% of the worlds manufacturing capacity is in five countries in Western Europe • These 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
Conclusion • Bird Flu is a serious virus and should not be overlooked • The virus will spread fast • Despite all of the efforts we make to prevent avian influenza if there is no efficient vaccine made than millions will die
