Viruses, bacteria, parasites, and fungi cause some of the deadliest illnesses on Earth.

Every pathogen depends on a small set of proteins to copy itself and survive in a host. Block one of those proteins and you can stop the infection. In viruses, two stand out: proteases, which cut newly-made viral proteins into working pieces, and polymerases, which copy the genetic code so new viruses can form. Folding@home has studied proteins like these for several of the infectious diseases below.
