The spread of eosinophilic DNA viruses refers to the spread of the virus in its natural host, apes, and birds, including in species and species.

Hepadnaviridae, also known as liver de-RNA virus section, Liver Virus section, mainly in vertebrates, and cause liver infection. There are two genera: Orthohepadnavirus, also known as the positive hepatic viral genus: Representative species: Hepatitis B virus (Hepatitis B VIRUS,HBV), referred to as hepatitis B virus. Avian liver de-rna virus genus: Avihepadnavirus, also known as avian liver virus genus; representative species: Duck hepatitis B virus (Duck hepatitis B VIRUS,DHBV). The eosinophilic DNA virus belongs to the double-stranded DNA retrovirus, which has a unique reverse transcription strategy, a very small genome (about 3.0~3.2 KB), and very narrow host-range and tissue-eosinophilic characteristics.

Hepatitis B virus is devastating, so its transmission by a large number of research, through the injection of vaccines and to a certain extent controlled, but due to the existence of a variety of potential, cross-species transmission, virus variants, species and species within the gene recombination, cross-infection, so that all kinds of control of hepatitis B virus transmission measures are facing setbacks.

Cross-species transmission has not been scientifically proven, but if this type of transmission occurs, it will enlarge the host range of the virus strains, reduce the host specificity of the virus strains, in order to control the spread of the virus to increase the difficulty, but also to try to reduce the hepatitis B virus infection through the way become more difficult to implement. As humans continue to invade the rainforest primate habitats, combined with attempts to protect the endangered primates, which increases the interaction between wild primates and humans, the cross-species retransmission of the positive liver virus provides the possibility. There have been many cases of cross-species infection between primates, and this inter-species infection, inter-primate and animal-to-human cross-species transmission, has also provided a great opportunity for gene recombination of the eosinophilic DNA virus strains, Further research suggests that the various types of eosinophilic DNA strains present in primates are likely to share the same old host.

Gene recombinationAlthough the host range of the eosinophilic DNA virus is small, the host specificity is likely to be significantly reduced with the possibility of cross-propagating potential, combined with gene recombination. Inter-species recombination, which exists in cross-species propagation, provides a great possibility for genomic mutation, not only to change the pathogen of the virus, but also to change its propagation ability and expand the host range. The first documented case of a potential genetic recombination occurred between the gorilla Hepatitis B virus (chimpanzee HBV) and the human HBV virus (HBV). The recombination of HBV strains and other apes, and the recombination of the HBV strains (GIHBV) from different kinds of hosts, as well as the reorganization of avian liver virus strains from different birds, were also confirmed. In short, these various possibilities are explained that human beings in the control of the transmission of hepatitis B virus will face a huge challenge. Although the transmission of hepatitis B virus is controlled through various treatments (such as injectable vaccines), but in the event of a growing population, increasing human activity and innovation (challenging natural limits), and increasing interaction between humans and animals, the above may become a fact if not taken timely and correct measures. Human health will also face challenges.
