Virus-Host Interactions

Virus-host interactions refer to the dynamic relationship between a virus and the cells or organisms it infects. When a virus enters a host, it attaches to a cell and injects its genetic material. This hijacks the cell’s machinery to replicate itself, often harming or killing the host cells in the process. The host's immune system responds by trying to detect and eliminate the virus, leading to an ongoing battle. The outcome can vary: the virus may cause disease, or the host may develop immunity, preventing future infections. Understanding these interactions helps in developing treatments and vaccines.
