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. Online journals follow a systematic pattern with a particular style which is universally followed to avoid confusion. All the information should be unbiased, readily proven and can be challenged in any kind of situation. Each and every fact should be made clear by providing proper evidence thereby encouraging true scholar and safeguarding copyrights. Following such stringent rules and evaluation can be costly, so publishers charge from the users who access the information, but, it will obstruct research as young researchers can afford it. Alternatively, fees can be charged from the researcher who has made the research and it can be free to the user who is interested in research thus, increasing the popularity and reputation to scholar and enhancing knowledge to user.
