Why does alcohol kill thrax in Osmosis Jones?

In "Osmosis Jones," alcohol kills Thrax, the virus, because it serves as a disinfectant that disrupts the virus's cellular structure. When Frank, the host, consumes alcohol, it raises his body temperature and creates an inhospitable environment for the virus. This weakened state allows Osmosis Jones, the white blood cell, to effectively combat and eliminate Thrax. The combination of alcohol's properties and the immune response ultimately leads to Thrax's demise.
