Canarias Leads the Way in Viral Surveillance with Cutting-Edge Genomic Sequencing
Researchers at the Hospital Universitario Nuestra Señora de Candelaria and the Instituto de Investigación Sanitaria de Canarias (IISC) have developed a new genomic sequencing tool for monitoring the respiratory syncytial virus (RSV). Published in Genome Medicine on January 27, 2026, this advancement promises to enhance the speed and accuracy of tracking viral evolution and potential treatment resistance.
From COVID-19 Lessons to RSV Vigilance
The project, initiated in 2023, directly builds upon the experience gained during the COVID-19 pandemic. Recognizing the critical role of genomic sequencing in understanding viral spread and mutation, the team aimed to create a refined method specifically for RSV. This method was fully developed in 2025 and has been progressively implemented for patient samples at the hospital.
Genomic sequencing identifies genetic changes in viruses, providing crucial insights into how they evolve. This knowledge is vital for anticipating increased transmission rates, greater disease severity, and potential changes in response to existing treatments and vaccines.
RSV: A Significant Public Health Concern
RSV is a leading cause of respiratory infections globally, particularly impacting infants under two years old and older adults. It’s highly contagious, spreading through respiratory droplets and direct contact. The virus is a primary driver of bronchiolitis and pneumonia in young children.
Spain introduced a monoclonal antibody for RSV prevention in infants in 2023, highlighting the need for continuous monitoring of the virus for potential resistance to this treatment.
Canary Islands’ Proactive Approach
In the Canary Islands, public health authorities recommend immunization for infants at six months of age during the RSV season (October to March), as well as for newborns during this period and high-risk children up to two years old. The Red de Vigilancia Epidemiológica de Salud Pública oversees clinical, epidemiological, and virological surveillance across the archipelago.
Initial findings from the Hospital La Candelaria study have not identified genetic changes associated with resistance to the new immunization. However, the team remains actively involved in genomic surveillance to detect any emerging resistance early on.
A Collaborative Effort: Hospital, Research Institute, and ITER
This breakthrough is a testament to the strong collaboration between the Hospital Universitario Nuestra Señora de Candelaria and the Instituto Tecnológico y de Energías Renovables (ITER). This partnership, sparked by the COVID-19 pandemic, has fostered an integrated system for genomic surveillance of emerging and re-emerging pathogens.
The project has received over three million euros in funding from the Fundación del IISC, the Instituto de Salud Carlos III, the Cabildo Insular de Tenerife, and the Fundación DISA, through its Biomedical Research Awards. It similarly benefits from the ‘Programa Investigo’ and co-financing from the European Union as part of the RELECOV 2.0 network.
The Future of Viral Surveillance: What’s Next?
The success of this initiative in the Canary Islands points to a broader trend: the increasing importance of genomic surveillance in public health. Expect to see more hospitals and research institutions investing in these technologies and collaborative networks.
Real-Time Data Analysis and Predictive Modeling
The ability to analyze samples “almost in real time,” as demonstrated by the collaboration between the Hospital La Candelaria and ITER, is a game-changer. This speed allows for rapid response to outbreaks and the development of targeted interventions. Future developments will likely focus on integrating this data with predictive modeling to anticipate viral spread and severity.
Expanding Genomic Surveillance Networks
The RELECOV 2.0 network exemplifies a growing trend towards national and international collaboration in genomic surveillance. Sharing data and expertise across borders is crucial for tracking viruses that can quickly spread globally.
Personalized Medicine and Targeted Therapies
As genomic sequencing becomes more accessible, it will play an increasingly important role in personalized medicine. Understanding the genetic makeup of a virus infecting a specific patient can help clinicians tailor treatment plans for optimal effectiveness.
