Viral specificity refers to the ability of a virus to infect particular host cells or tissues based on specific interactions between viral surface proteins and host cell receptors. This specificity is crucial for the virus to successfully enter and replicate within a host cell, leading to an infection. Different viruses have different levels of specificity for target host cells or tissues.
Viruses have proteins in their capsid which match proteins in the membrane of their preferred host. This produces the ability to "dock" and then enter the host cell.
Virus specificity refers to the ability of a virus to infect specific host cells or organisms due to interactions between viral and host cell surface molecules. Each virus has a specific range of hosts that it can infect based on these molecular interactions, which determine its infectivity and pathogenicity. This specificity is what underlies the diverse range of diseases caused by different viruses.
Host specificity of a virus is primarily determined by the receptors on the host cell that the virus can bind to. Different viruses have specific receptors that they recognize and bind to on the surface of host cells, which allows them to infect only specific types of cells in specific species. Additionally, the ability of a virus to successfully replicate and complete its life cycle within a particular host also plays a critical role in determining host specificity.
The most important factor for attachment of a virus to a host cell is the specific interaction between viral surface proteins (such as spike proteins) and host cell receptors. This binding is key for the virus to gain entry into the host cell and initiate infection.

Enzymes exhibit different types of specificity, including substrate specificity (acting on a specific substrate), stereospecificity (acting on a specific stereoisomer), and regiospecificity (acting at a specific region of a substrate). For example, trypsin exhibits substrate specificity by cleaving peptide bonds after lysine or arginine residues, while lactase exhibits substrate specificity by hydrolyzing lactose.
