Viral Pathogenesis
Viral pathogenesis refers to the process by which viruses cause disease in their hosts. It begins when a virus enters the body, often through respiratory droplets or contact. Once inside, the virus infects cells, takes control of their machinery to replicate itself, and spreads. This can damage or destroy cells, leading to symptoms like fever or inflammation. The body’s immune response tries to fight off the virus, which can also contribute to symptoms. Ultimately, the severity of the illness depends on the virus’s characteristics and the host's immune response.

Viral pathogenesis refers to the process by which viruses cause disease in their hosts. When a virus enters the body, it attaches to and infects specific cells, using them to replicate and spread. This can harm or kill the cells, leading to symptoms such as fever, cough, or fatigue. The virus may also trigger an immune response, which can cause inflammation and additional symptoms. The severity of the disease depends on factors like the virus type, how it spreads, and the host's immune system. Understanding this helps in developing treatments and preventive measures, like vaccines.

Viral pathogenesis refers to how viruses cause disease in a host. When a virus enters the body, it attaches to and invades host cells, using them to reproduce. This process can damage or destroy the cells, leading to symptoms like fever, fatigue, or inflammation. The immune system responds to fight the virus, which can also contribute to symptoms. Different viruses have unique mechanisms of causing disease, and factors like the virus type and the host's immune response determine the severity of the illness. Understanding viral pathogenesis helps in developing vaccines and treatments.
