Influenza :
Influenza, which is better known as the flu, is a viral infection. It affects the lungs, throat, and nose, causing symptoms like coughing, sneezing, runny nose, and shortness of breath. It can also cause fever, sore throat, body pain, headache, and tiredness. This condition usually causes severe symptoms, unlike the common cold, which can cause similar symptoms of a milder intensity. The flu is contagious and common in the winter. It can cause thousands of people to fall sick simultaneously. This infection can last for up to two weeks. The flu can be dangerous and even life-threatening to individuals who have underlying conditions or are pregnant. People with diabetes, asthma, heart problems, and obesity may need to be hospitalized to recover. Treatment for the flu usually comprises antiviral medication. Taking the medication can not only reduce the symptoms but also speed up recovery.
