The event has been organised by the Catholic Church and will see an estimated 500,000 people gather in Panama city to take part in the gathering between 22 and 27 January. Over the course of the event, open air masses and religious processions will take place for pilgrims, priests and nuns from around the world.
The ECDC advises that travellers attending the event should have received at least two doses of measles-containing vaccine as well as vaccination against mumps, rubella, diphtheria, tetanus, pertussis and polio. Vaccination against hepatitis A and typhoid should also be considered, while seasonal influenza vaccine and Meningococcal ACWY vaccine may also be considered, the ECDC says.
The agency is also advising that travellers should use personal protective measures against mosquito bites to prevent mosquito-borne diseases such as yellow fever, Zika, dengue, chikungunya and malaria.
The ECDC said it will closely monitor the event through routine epidemic intelligence activities between 14 January and 3 February 2019, and will report on a weekly basis.
