14 Mar 2023 • As flu season begins in many parts of the world, there is a lot of confusion about the symptoms and differences between the flu and COVID-19. Medical experts explain that both illnesses are respiratory infections, but caused by different viruses with varying symptoms.

Symptoms of Influenza

Influenza viruses, including H3N2 and H3N1, typically cause fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue. Nausea, vomiting, and diarrhoea can also occur, especially in children.

Symptoms of COVID-19

COVID-19 symptoms can include fever, cough, shortness of breath, fatigue, body aches, headache, loss of taste or smell, sore throat, congestion, and running nose. In severe cases, COVID-19 can lead to pneumonia and other serious complications.

Prevention and Treatment

Both illnesses can be prevented through simple measures such as washing hands regularly, avoiding overcrowded places, wearing face masks, and maintaining physical distance. Antibiotics are not effective against either illness, as they are viral infections. Patients with severe symptoms may require hospitalisation and supportive treatment.

Expert Advice

Dr Laxman Jessani, Consultant in Infectious Diseases at Apollo Hospitals, advises that prevention is key to combating both illnesses. Dr Arunesh Kumar, Senior Consultant and Head of Pulmonology and Respiratory Medicine at Paras Hospital, warns that elderly patients or those with underlying health conditions are at increased risk of developing severe illness. It is important to seek medical attention if symptoms persist or worsen.
