For a second consecutive year, the world is celebrating Christmas with the threat of COVID-19 dampening the festivities. Many countries, including the United States, the United Kingdom and others, are experiencing a fresh surge in cases fuelled by the more transmissible omicron variant of the coronavirus. This ‘variant of concern’ has already become the dominant strain in the US, while the UK is reporting record daily cases everyday. Several countries have limited or cancelled Christmas and New Year gatherings in order to prevent a fresh outbreak. However, the holiday spirit is high and people across the world are celebrating Christmas with fervor.
