What is Influenza?
Influenza is a contagious respiratory illness caused by influenza viruses. It can lead to mild to severe illness and can sometimes result in hospitalization or death. Symptoms include fever, cough, sore throat, body aches, and fatigue. The virus spreads mainly through droplets made when infected people cough, sneeze or talk.
How is it Treated?
There are antiviral medications available that can lessen symptoms and shorten the duration of the flu if taken early. Over-the-counter medicines can also help alleviate symptoms like fever and aches. Rest and hydration are crucial for recovery. People at high risk for complications should see a doctor promptly if they suspect they have the flu.
Flu vs. Cold: Know the Difference
While both the flu and the common cold affect the respiratory system, they are caused by different viruses. The flu usually comes on suddenly and is more severe than a cold, which generally has milder symptoms. Knowing the difference can help you seek appropriate treatment and care.
