Flu (Influenza)
Influenza, commonly known as the flu, is a contagious viral infection that affects the respiratory system. It can range from mild to severe and often begins suddenly, typically within two days of exposure to the virus.
Common Symptoms:
• High fever
• Runny or blocked nose
• Sore throat
• Muscle and joint pain
• Headache
• Cough
• Fatigue and weakness
In some cases, especially in children, symptoms like vomiting and diarrhoea may occur. While most people recover within a week, a persistent cough can last longer. Serious complications may include pneumonia, sinus infections, or worsening of existing conditions like asthma or heart disease.
Causes:
• Infection by influenza viruses (Types A, B, and C)
• Spread through droplets from coughs and sneezes
• Touching contaminated surfaces and then touching the face (eyes, nose, mouth)
• Close contact with infected individuals
Prevention Tips:
• Get vaccinated annually against influenza
• Wash hands frequently with soap and water
• Wear a mask in crowded or high-risk areas
• Avoid close contact with infected individuals
• Maintain good hygiene and a strong immune system through proper diet and rest
Taking preventive measures and staying informed can help reduce the risk of infection and protect both yourself and those around you.
