👉 Residential infection, also known as resident viral infection, refers to the persistence of a virus within a host's body for extended periods, often in specific cell types or tissues, even after the initial acute infection has resolved. This can occur when the virus establishes a latent or chronic state, where it remains dormant or replicates at very low levels without causing immediate symptoms. For example, herpes simplex virus (HSV) can reside in nerve ganglia, and human immunodeficiency virus (HIV) can integrate into host cell DNA, remaining hidden from the immune system. This prolonged presence allows the virus to reactivate under certain conditions, such as stress or a weakened immune system, leading to recurrent infections. Understanding residential infection is crucial for developing long-term treatment strategies and preventive measures against persistent viral diseases.
