Seasonal infections are doing the rounds: what you should know

Seasonal infections are on the rise across India, with viral respiratory infections like influenza and Covid-19 being particularly common in the lead-up to the northeast monsoon in Tamil Nadu. With the arrival of the monsoon rains, there's also been an increase in dengue due to mosquito breeding, and bacterial infections such as gastroenteritis and typhoid. The change in season is the primary reason for these spikes in infections.

Respiratory viral infections are highly seasonal and linked to rainfall, with the monsoon having a significant impact on transmission. In Chennai, while most places don't see a rise in respiratory infections during this time, the extra rainfall this year has led to a noticeable spike. Dengue and influenza are also viral infections that tend to be short-lived.

Non-specific fevers, characterized by fatigue and mild symptoms, are most likely viral illnesses. However, if fever persists for over five days or is accompanied by symptoms like shortness of breath, burning during urination, or jaundice, medical attention is needed. High-grade fever with shivering or chills can indicate a bloodstream infection requiring immediate medical help. Self-medication with antibiotics other than paracetamol is not recommended, as fever is a symptom rather than a specific disease.

Precautions learned during the Covid-19 pandemic, such as wearing masks and practicing good hand hygiene, remain crucial when dealing with respiratory viral infections. Workplace environments, often centrally air-conditioned, can exacerbate germ proliferation, making respiratory etiquette, frequent cleaning, and hand hygiene even more vital.

Fever duration, severity, and localizing symptoms can help differentiate between viral and bacterial infections, guiding appropriate medical action. Chronic medical conditions, like diabetes, should also be carefully managed, as they can influence the severity of illness.
