Overview: a rising tide of IRAS
In the latest public health update, respiratory infections (IRAS) have risen to around 40,000 weekly cases in the past month. The rebound began in epidemiological week 33—the third week of August—when 33,143 infections were reported. A week later, cases reached 35,857 and continued to climb in the days that followed, approaching the 40,000 mark. Health authorities emphasize that these figures reflect reported episodes and may vary with testing rates and reporting practices.
What is driving the surge?
Experts point to a combination of seasonal factors, increased viral circulation, and broader testing coverage. Changes in weather can favor respiratory viruses; co-circulation of influenza, respiratory syncytial virus (RSV), and other pathogens complicates diagnosis and management. While vaccines and public health measures help, a seasonal uptick in IRAS is not uncommon. The key for clinicians and patients is early recognition of warning signs and careful medication use to avoid masking symptoms or triggering side effects.
Medications that can aggravate the clinical picture
- Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can relieve fever and pain but may mask fever, delay care, or worsen dehydration, especially in older adults or those with kidney disease. Use with caution and follow clinician guidelines.
- Systemic corticosteroids (oral or injected) can suppress the immune response if used inappropriately. They are essential for specific inflammatory or chronic conditions but may complicate viral infections when used without a clear indication.
- Decongestants (pseudoephedrine, phenylephrine) can raise blood pressure, cause tachycardia, and worsen dehydration. They may interact unfavorably with cardiovascular disease or glaucoma and should be used only as advised.
- Antihistamines (first-generation) can dry mucous membranes, thickening secretions and potentially hindering airway clearance, particularly in older adults or those with underlying lung disease.
- Cough suppressants containing codeine or high-dose dextromethorphan can cause drowsiness and confusion, especially in the elderly or those taking other sedatives. They should be used judiciously and under guidance.
- Antibiotics are not effective against viral infections like many IRAS cases. Misuse or overuse can cause side effects, antibiotic resistance, and microbiome disruption. Reserve antibiotics for confirmed bacterial infections as prescribed.
Practical guidance for safer use
Patients should read labels, avoid combining multiple products with the same active ingredient, and consult a clinician before starting new medicines during an IRAS episode. Non-drug measures—hydration, rest, humidified air, and fever control with paracetamol where appropriate—can help while awaiting recovery. Clinicians will tailor therapy to the individual, considering age, comorbidities, and current medications.
When to seek urgent care
Red flags require immediate medical attention: trouble breathing, chest pain, bluish lips or face, new confusion, inability to drink fluids, or a fever that lasts beyond a few days or worsens despite home care. Vulnerable groups—the elderly, young children, pregnant people, and those with chronic illnesses—should seek prompt evaluation if symptoms arise or worsen.
Bottom line
As weekly IRAS cases approach 40,000, awareness of how medicines can influence the course of illness is crucial. Use medications wisely, avoid self-prescribing multiple agents, and consult healthcare professionals to optimize safety and outcomes during this respiratory infections surge.
