<P> Mitch returns home and finds that Clark has also died from a similar infection . Mitch is placed in isolation but seems to be immune to the disease . He is released and returns home to his teenage daughter Jory, though they are unsure if she has inherited his immunity . She decides to stay with her father regardless, since he's now all alone . Mitch struggles to protect his daughter from the risk of infection, while learning that his wife was unfaithful to him prior to her death . Meanwhile, everyone who had contact with Emhoff begins to spread the disease around the world . </P> <P> In Atlanta, representatives of the Department of Homeland Security meet with Dr. Ellis Cheever of the CDC and express fears that the disease is a bio weapon terror attack over the Thanksgiving weekend . Dr. Cheever dispatches Dr. Erin Mears, an Epidemic Intelligence Service officer, to Minneapolis to begin investigating . Mears traces the U.S. outbreak to Emhoff, while also dealing with local bureaucrats who are initially reluctant to commit to a proper public health response . After successfully setting up triage camps in large venues, Dr. Mears becomes infected . Her evacuation is postponed, as airports begin to close in anticipation of a quarantine . She later dies and is buried in a mass grave . As more and more people become infected with no cure in sight, social order begins to decay, with rampant looting of stores and homes . The U.S. President is moved underground while emergency services suffer absenteeism and no longer respond . Mitch and Jory attempt to escape to Wisconsin, but the borders are closed . </P> <P> At the CDC, Dr. Ally Hextall determines the virus is a mix of genetic material from pig and bat viruses . Work on a cure stalls because scientists cannot discover a cell culture within which to grow the newly named Meningoencephalitis Virus One (MEV - 1). </P> <P> UCSF professor Dr. Ian Sussman violates orders from the CDC to destroy his samples, and on Day 12, with over 8 million already infected worldwide, identifies a usable MEV - 1 cell culture using bat cells . Hextall uses the breakthrough to start working on a vaccine . Other scientists determine the virus is spread by fomites with a basic reproduction number of four when the virus mutates, projecting that one in twelve of the world population will be infected, with a 25 - 30% mortality rate . </P>
