Animal viruses cause various types of infection. In lytic infections, the virus will break open or lyse the host cell, resulting in the destruction of the host cell. Other viruses may cause persistent infections. In this type of infection, the virus may go dormant and be reactivated at a later time. The host cell may or may not be destroyed. Some viruses can cause persistent infection in different organs and tissues at the same time. Latent infections are a type of persistent infection in which the appearance of disease symptoms does not happen immediately, but follows after a period of time. The virus responsible for the latent infection is reactivated at some later point, usually prompted by some type of event such as infection of the host by another virus or physiological changes in the host. HIV, Human Herpes viruses 6 and 7, and the Epstein-Barr Virus are examples of persistent virus infections that are associated with the immune system. Oncogenic viral infections cause changes in host cells, turning them into tumour cells. Journals are the major source of knowledge for young and aspiring generations who are keen in pursuing their careers in science. This system provides easy access to networks of scientific journals. Authors who contribute their scholarly works to Open Access journals gain remarkable reputation as the research scholars explore these works extensively. This process assures considerable impact factor for the journal and good reputation to the authors that add value to their Academic Performance Index (API) Score. Because of the free access open access journals impact factors are improving.
