Respiratory viruses continue to plague the Dominican population.

The Dominican Republic is confronting an unusually severe and prolonged respiratory virus season, with epidemiological data revealing significantly elevated levels of viral circulation. According to the latest bulletin from the Ministry of Public Health (Bulletin 49), 2025 has witnessed a steady escalation in respiratory virus activity, marked by the persistent co-circulation of influenza A and B, SARS-CoV-2, adenovirus, parainfluenza, and metapneumovirus.

This complex viral landscape presents substantial public health challenges, including increased risks of co-infections, respiratory complications, and mounting strain on healthcare infrastructure. The epidemiological pattern aligns with broader hemispheric trends reported by PAHO/WHO, indicating recent respiratory seasons have grown more intense, irregular, and extended in duration.

The most significant epidemiological development of 2025 is the unprecedented behavior of Respiratory Syncytial Virus (RSV). Surveillance data shows a dramatic surge beginning in epidemiological week 38, with infection rates peaking between weeks 40-45 at levels far exceeding those recorded throughout 2024. This RSV surge has generated substantial cases of bronchiolitis and pneumonia, driving increased hospitalizations among infants who developed heightened susceptibility following seasons of low viral exposure.

Environmental factors including frequent rainfall, elevated humidity levels, and temperature fluctuations have contributed to enhanced viral transmission dynamics. This pattern mirrors observations from multiple nations including the United States, Canada, Brazil, and Chile, where RSV has demonstrated earlier emergence and larger infection peaks.

The current epidemiological situation has precipitated increased demand for emergency services, pediatric hospitalizations, and intensive care resources. Minor fluctuations in respiratory virus curves now translate to significant operational pressures on healthcare delivery systems.

In response, health authorities have strengthened virological surveillance through expanded sampling protocols and enhanced real-time reporting via the SINAVE system. Additional measures include intensified monitoring of bed occupancy rates, activation of rapid referral pathways for critically ill pediatric patients, and ensuring availability of essential medical supplies.

Preventive strategies include promoting influenza vaccination among vulnerable populations and implementing community interventions focused on respiratory hygiene, reduction of overcrowding, and encouraging early medical consultation. Despite these efforts, structural challenges persist including limited ICU and neonatal ICU capacity alongside disparities in territorial healthcare access.

This complex epidemiological scenario underscores the necessity for sustained, multi-sectoral strategies to reduce illness burden during an increasingly active and prolonged respiratory virus season.
