How is African swine fever caused? An analysis of the causes and transmission routes
In this year's farming industry, African swine fever is absolutely the most eye-catching topic. Many people who have raised pigs for over a decade say they have never seen such a severe epidemic, which caught farmers off guard. First, let's look at how African swine fever is caused.
How is African swine fever caused
African swine fever is caused by the African swine fever virus (ASFV) of the genus African swine fever virus in the family African swine fever virus. It is an acute, severe, highly contagious infectious disease of pigs and wild boars, with a high incidence rate and a mortality rate of up to 100%. The symptoms and necropsy lesions it causes are very similar to those of classical swine fever. Because it originated in the African region, it is called African swine fever. It is currently endemic in some areas of Africa, Europe and Latin America.
African swine fever (ASF) is a severe infectious disease of pigs caused by infection with the African swine fever virus (ASFV). Pigs of all ages are susceptible, and the incidence and mortality rates can be as high as 100%. The African swine fever virus belongs to the order DNA viruses, the family African swine fever virus, and the genus African swine fever virus. It is a double-stranded DNA virus.
The mature ASF virion of the family African swine fever virus is icosahedral in symmetry, with a diameter of about 200nm. From inside to outside, it consists of five parts: the viral genome, the inner core shell, the inner membrane, the capsid and the envelope.
How did African swine fever spread to China
African swine fever is an acute, hemorrhagic, severe infectious disease caused by infection with the African swine fever virus in domestic pigs and various wild boars (African wild boar, European wild boar, etc.). Since it was first introduced into China in August 2018, as of March this year, official reports show a cumulative total of 112 outbreaks.
