The people in North Rhine-Westphalia ask themselves this question after Prime Minister Laschet’s announcement of a “hard lockdown”: How risky is it to celebrate Christmas with the family despite Corona? Help is available from the Max Planck Institute for Chemistry in Mainz. The researchers have calculated how high the risk of infection is under various conditions such as room size, number of guests, ventilation and more.
