The World is Fighting COVID-19
Stamps from all over the world
Several postal administrations have decided to issue postage stamps to commemorate this tragic event, as a tribute to those who fight dangerous contagion in the front lines: doctors, nurses, medical staff, scientists, firefighters, police, soldiers, and so on.
Another reason for issuing these postage stamps is the efforts of the issuing countries to raise public awareness, which, together with effective personal hygiene and protection measures, is the most effective means of combating this pandemic. Source: Postoveznamky.
