Seasonal infections are increasing in parts of India as changing weather conditions and monsoon rainfall contribute to the spread of respiratory illnesses and other diseases. In Tamil Nadu, ahead of the northeast monsoon, doctors are reporting cases of influenza, COVID-19 and other respiratory viral infections, alongside a rise in dengue, gastroenteritis and typhoid.
Increased rainfall can contribute to the spread of respiratory viruses, while stagnant water creates favourable conditions for mosquito breeding and dengue transmission. Chennai, which does not typically experience the same rise in respiratory infections during this period, is also seeing an increase this year amid heavier rainfall.
Maintaining personal hygiene is important during the seasonal infection period. Regular handwashing and safe drinking water practices can help reduce the risk of infections, particularly those that spread through contaminated food or water. Preventing mosquito breeding around homes and workplaces is also important during the rainy season.
Respiratory infections can spread between people, making precautions particularly relevant for older adults and other vulnerable individuals. Wearing a mask when appropriate and staying home when unwell can help limit the spread of illness. Taking adequate rest and avoiding contact with others while experiencing symptoms are also useful precautions.
People should avoid self-medication beyond basic fever relief with paracetamol and seek medical advice when symptoms require further assessment. A fever that persists for more than five days, or symptoms suggesting that other organs may be affected, should prompt a medical consultation.
As seasonal infections circulate, early medical evaluation, good hygiene and preventive measures can help people respond appropriately and reduce the risk of complications.
