The Jubilee 2025 is a special holy year of the Catholics which occurs once every 25 years, involving major religious mass gathering events in Rome which are attended by millions of pilgrims from all around the world. In 2025, starting from 24 December 2024 until December 2025, it is estimated that more than 35 million pilgrims will visit Rome
The probability of European citizens becoming infected with communicable diseases during the Jubilee 2025 is low if general preventive measures are applied (e.g. being fully vaccinated according to national immunisation schedules, following advice regarding hand and food hygiene and respiratory etiquette, self-isolating with flu-like symptoms until they resolve, wearing a mask in crowded settings, seeking prompt testing and medical advice as needed, and practising safe sex). This is particularly important in relation to vaccine-preventable diseases that may be on the rise, such as measles, whooping cough, and COVID-19.
