2020 pandemic and it's aftermath

Humanity lived in a globalized world in the first decades of the 21st century. It created enormous prosperity especially from evolving telecommunication including the Internet and mobile phones evolved from telegraphs which started to create a global network as well as the ability to travel anywhere throughout the world. Humans thought improved communications and technology would lead them to a utopian dream seen in such science fiction works such as Star Trek. However, in that fateful year of 2020, a pandemic known as COVID-19, thought to have originated in China's Wuhan province through it's food markets and/or thought to be combined with 5G technology, ravaged the globe. Everyone was in fear. Humanity, especially in the prosperous West, was not prepared for such a plague. Fear and confusion eventually led to panic. The lucky ones eventually make it out of the cities, which were the hardest hit. It caused everything to shut down, first entertainment and mass media, then the economies and eventually the governments collapsed. Factions took over, including militias, controlling the food supply and stockpiling weapons, reverting humanity back to a feudal society much like medieval Europe after the fall of Rome. No one truly knew how one virus could end a globalized world, but some are hopeful that one will eventually find out.
