Allergic rhinosinusitis and seasonal allergy symptoms have extended from their traditional months into a nearly year-round condition driven by local climate factors, humidity, and rising atmospheric pollen counts, according to Dr. Nora Giovino, a specialist who consults monthly at the Instituto del Diagnóstico.
Climate Factors and Year-Round Pollen Dissemination
The city of Las Flores experiences persistent humidity throughout the year due to geographical features and climate shifts. Dr. Giovino explains that the combination of moisture from the Salado River, flooding, and warm weather creates an environment where aero-allergens thrive continuously. Common local trees including plane trees, lindens, and ashes release pollens that interact with humidity mold and the pampean grassland region. While pollen seasons historically ran from November to January, local pollination cycles now stretch from late August through early May, making allergens effectively perennial.
Symptoms and Clinical Presentation
Allergic rhinosinusitis triggers significant physical discomfort across multiple age groups, ranging from children to older adults. Patients frequently experience burning, itchy, and watery eyes accompanied by clear, gelatinous mucus that drips down the back of the throat. This post-nasal drip can provoke a dry, persistent cough and, when irritation extends further into the respiratory tract, may cause bronchospasm characterized by a wheezing sound. Dr. Giovino notes that as maxillary sinuses fill with mucus, the resulting laryngeal irritation produces a cough that is difficult to interrupt.
Diagnostic Testing and Treatment Strategies
Identifying specific allergy triggers involves targeted blood and skin testing. While genetic predisposition means patients cannot cure the underlying condition entirely, treatment can desensitize the patient and drastically reduce symptom severity. For individuals working outdoors in trades such as construction, painting, or mechanics, Dr. Giovino recommends wearing industrial-grade double masks with proper filtration during peak exposure hours.
Global and Regional Allergy Trends
Environmental changes, increased agricultural chemical use, and higher pollution levels from diesel exhaust have increased overall sensitivity rates in the general population. Worldwide allergy prevalence, currently at 25%, is projected to reach 40% by 2035 as previously latent sensitivities become active due to environmental shifts. In moisture-dense urban environments, ambient fog further elevates humidity levels, accelerating the rapid growth of dust mites and pollen.
