Within the framework of DxHub, a citizen science project is being developed at Agrupamento de Escolas de Paço de Arcos (SCPA), in a collaboration ith the Ciência + Cidadã Programme and with the support of the Municipality of Oeiras. The initiative engages students in scientific practices related to the analysis of waterborne pathogens, with a particular focus on Legionella spp., including the use of a point-of-care (PoC) device currently being developed by STAB VIDA. The data generated by the students will contribute to the validation of this rapid and portable test for Legionella detection, supporting infection prevention and the control of epidemiological outbreaks. The project aims to strengthen scientific literacy in health, foster civic participation, and bring students closer to research, innovation, and the challenges affecting their own community.
Learning Through Science
The project is being developed during the 2025/26 school year with 56 students from two 7th-grade classes. Its theoretical component is integrated into the Citizenship and Development Project, while the practical component takes place in the school’s Science Club. Four 12th-grade students, members of the same club, act as peer mentors after receiving practical training at STAB VIDA on the diagnosis of infectious diseases using rapid and portable tests, including the Doctor Vida device. Researchers from DxHub partner institutions, namely from ITQB NOVA, IHMT NOVA and INIAV, also contribute to the project. This peer-to-peer model strengthens collaboration, critical thinking, and autonomy, while helping younger students engage with scientific work in an accessible and meaningful way.
Hands-On Activity and Data Collection
On 21 and 22 January 2026, the students took part in a hands-on activity focused on the collection and analysis of water samples for the detection of Legionella spp. at the school, using a point-of-care test currently being developed by STAB VIDA. Samples were collected from points considered to present a higher risk, namely showers, condensers, and taps.
The sampling process was guided by researchers from STAB VIDA, together with a technician from SIMAS, the entity responsible for monitoring water quality in the municipality of Oeiras. To support validation of the results, half of the collected samples were analysed in SIMAS laboratories, allowing comparison with the results obtained using the STAB VIDA point-of-care device under evaluation.
To complement the practical experience and provide insight into routine laboratory procedures, students also visited SIMAS laboratory facilities. One introductory visit took place in early December 2025 with the four Science Club students, and two further visits were organised on 21 and 22 January 2026 for the 7th-grade students involved in the sampling activities.
Impact, Outreach, and Civic Engagement
At the end of the project, the students will present their results to the school community and prepare a report with recommendations for the Municipality of Oeiras. They may also take part in a Youth Citizens’ Assembly within DxHub, encouraging dialogue, democratic participation, and intergenerational exchange around science and health.
The project also aims to involve students as ambassadors at public outreach events such as the European Researchers’ Night, extending their engagement with science beyond the classroom.
By connecting students with issues relevant to their community and to the One Health concept, DxHub AquaDetect seeks to promote participation in science and inspire a new generation of informed, active, and health-conscious citizens.
