The city is witnessing a surge in viral infections, with fever, cold, cough, sore throat, body ache and weakness being the main symptoms. From children to adults, several households are reporting a pattern where one family member falls sick and others develop similar symptoms within days. The combination of changing weather, intermittent rainfall and increased exposure to infections is contributing to seasonal rise in viral illnesses. Doctors, however, say people should not panic but must remain alert, particularly those vulnerable to respiratory complications. Dr Nainesh Patel, MD, Respiratory Medicine; says, “Influenza viruses change their strains every year, which can result in differences in symptoms and severity.

 

The virus changes every year. This year, H1N1 is the predominant strain, while last year it was H3N2. Depending on the strain, the symptoms can vary.” Explaining the importance of vaccination, Dr Patel said the influenza vaccine is updated every year based on the strains expected to circulate. “World Health Organisation (WHO) studies the viruses prevalent in different populations and predicts the strain likely to predominate. Based on these recommendations, pharmaceutical companies prepare the vaccine in advance,” he added. Vaccination can provide protection for around nine to 10 months. “Viral infections cannot always be prevented.

 

Even after vaccination, a person may get infected, but it is less likely to become severe, recovery can be faster and complications such as respiratory distress requiring ICU care can be reduced,” added Dr Patel. Doctors advise citizens to avoid close contact with people showing flu-like symptoms. Wear a mask at crowded places if experiencing cough or fever. Take adequate rest and fluids during illness. Avoid self-medication and antibiotics without medical advice. Doctors particularly advise people with cardiac, lung or kidney diseases, diabetes and other underlying conditions to remain cautious and discuss influenza vaccination with their physician.
