A virus that only infects cells of a specific tissue in the body is described as having a "tissue tropism." Tissue tropism refers to the preference of a virus to infect particular types of cells or tissues. This specificity is often determined by the presence of specific receptors on the host cells that the virus can bind to, as well as the virus's ability to replicate within those cells. For example, the influenza virus primarily targets respiratory tract cells, while HIV specifically infects CD4+ T cells in the immune system. This characteristic of viruses is crucial for understanding their pathogenicity and the body's immune response to infection.
