Possible Mechanism Triggered by Viral Infection in AIDs An acute or chronic viral infection is thought to play a crucial role as a triggering phase of the immunological instability that is required for the formulation … Hepatitis A Pathogenesis. Virology. They can be localized or systemic. Inflammation is a complex tissue reaction to injury that may be caused by physical, chemical, or immunological agents or even by radiation. Poxvirus infections, in general, are acute, with no strong evidence for latent, persistent, or chronic infections. stream It is likely that the initial infection is within the oronasal mucosa and that spread from this site is systemic. Viral latency can also be seen in the development of several chronic … Considering viral diseases, there are two components involved, the direct effect of virus replication and the effects of bodily responses to the infection.

Pathogenesis of Viral Infection Mark T. Heise Herbert W. Virgin Introduction to Viral Pathogenesis Viral pathogenesis is the series of steps that occurs when a virus infects the host. The first step in infection is virus binding to a host cell through its target receptor. 0000026872 00000 n 2.

PATHOGENESIS After the infection virus is disseminated within the monocytes, macrophages, den-dritic cells to the lymph nodes, and then by blood to the spleen and liver [7, 10]. Viruses infect cells and proliferate to cause viral infections. Here, the virus resides quiescently, occasionally reactivating to infect new B cells, completing the cycle of infection.
