I am aware of two alternate time lines. Here is the first. There was a massive influenza viral event which resulted in fundamental changes to everyday behavior in this country. The short story was a pandemic viral event started as what looked like a typical outbreak of influenza. The first patient identified had been on a flight that landed in a major east coast city. Within two days cases were reported in other cities. Large numbers of people became severely ill and hospitals were overwhelmed. The news was reporting on the epidemic nightly. In locations where large cases were occurring, states of emergency were declared where people were urged not to leave their houses. Workplaces closed in an effort to prevent further spread. Air travel was curtailed. People were afraid of going outside. People did not want to handle paper money and coins. Banking and the markets and businesses were crippled. The virus was especially virulent as it attacked both the respiratory system as well as organs causing increased mortality. After about 12 weeks the cases and deaths began to subside. So many were dead. Following the aftermath and very long recovery, no doors had handles they were either automatic or had kick plates where everyone used their feet to open them. Paper money was abolished. People remained very wary of sickness. No one shook each others hand anymore. An individual created some sort of solenoid that allowed for cool plasma to be used to sanitize hands. This was present in a device about the size of one of those hand dryer blowers in bathroom no one used faucets in public bathrooms they used these instead. It was mandatory for people who were ill to not be allowed at work and this was enforced as the anxiety over another epidemic was so prevalent. So many people had been lost and it disrupted the infrastructure to such a degree for such a long time that people just would not take the chance. After the event, it was determined that the actual origin of the virus was not natural. It was traced to a researcher who created a hybrid influenza strain that would be highly virulent in respiratory and to the nervous system causing organs to fail. The researcher was not allowed to publish his work for national security reasons as publication would include the hybridization methodology. the researcher became disgruntled and released the virus on flights seeding the epidemic.
