On March 2020, the World Health Organization (WHO) declared the situation of pandemic due to COVID-19. The purpose of this article is to share an experience of community healthcare through Health Education, conducted in the Eastern half of the Huesca province (Spain). The objective of the project was to improve the management of measures to prevent infection by SARS-CoV-2 in the population. The activity was conducted between June and August 2020, and it was led by Primary Care nurses. There were four stages of work in different settings: general population, sociosanitary, and teaching (professors and students). Common contents were included (general concepts, hand hygiene, type of masks and their correct use, social distance, correct use of gloves, protocol of action in case of contact or contagion), as well as specific contents for the different groups, addressed in a practical manner. Almost 500 hours were spent in 369 sessions. It was estimated that over 9,000 persons participated (approximately 9% coverage of the total population of the Healthcare Area). There was also high satisfaction in the participants surveyed. This difficult situation has shown the ability of nurses regarding reaction, adaptation, commitment, and teamwork.
