What is influenza (flu)?

Influenza, commonly known as the flu, is a contagious respiratory illness caused by the influenza virus. It can cause mild to severe illness, and in some cases, it can lead to complications that can be life-threatening. The flu virus is easily transmitted from person to person through respiratory droplets when an infected person coughs or sneezes.

Flu Symptoms

The common symptoms of the flu include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue. In some cases, it can also cause vomiting and diarrhea, especially in children.

Flu Causes

The flu is caused by different strains of the influenza virus, primarily influenza A and B. These viruses can mutate and evolve, making it challenging to develop long-lasting immunity.

Flu Treatment

Treatment for the flu typically involves rest, staying hydrated, and taking over-the-counter medications to relieve symptoms. In some cases, antiviral medications may be prescribed to shorten the duration of the illness.

Preventing the Spread of the Flu

Prevention is key to protect yourself and others from the flu. Getting vaccinated, practicing good hand hygiene, avoiding close contact with sick individuals, and staying home when sick are all important measures to prevent the spread of the flu virus.
