Avian flu is cause by avian influenza (H5N1) virus. main cause: caused by infected birds which secrete the virus through saliva, mucus and feces. birds may get infected by infected poultry, surface contact eg: dirt, cages or materials and food such as water that contains the virus.
people who eat raw or uncook meat, working with poultry and affected countries have higher risk of getting avian flu.
there are 3 types of influenza viruses, A, B and C. which only A could be found in humans and animals whereas B and C can only be found in humans. type A are divided into strains and may be potentially harmful.
how to prevent: People who work with birds who might be infected should use protective clothing and special breathing masks. Avoiding undercooked or uncooked meat reduces the risk of exposure to avian flu.
as egg is the main thing that causes avian flu, ways to ensure safety of the product may be get eggs supplied from countries that are not affected and safe from avian flu. and perhaps to wash eggs shells before using it to crack the egg if in any case there is any viruses on the eggs shell.
