The economy is affected in a totally unknown way. Governments have had to face some challenges they themselves are discovering only now; they get inspiration from other countries for what to do to keep the societal balance, including the physical and mental health of the population. Almost everywhere in the world, for those lucky enough to have the option, one can work from home; shops with non-essential products are closed as are gyms, hair salons, and restaurants. Concert, festivals, weddings with many guests will most likely be cancelled in 2020. There are also professional events that are postponed or canceled. In aviation, for example, March, April and May are the busiest months in terms of conferences, meetings or fairs.
