Preventing Influenza (Flu): Vaccines and Everyday Tips

What is Influenza (Flu)?

Influenza, often called the flu, is a common viral infection. It affects your nose, throat, and sometimes your lungs. Influenza prevention is important because the flu can spread quickly, especially in crowded places. According to the CDC, millions get the flu each year. While most people recover, some can get very sick.

Symptoms of Influenza

Flu symptoms usually start suddenly. They can range from mild to severe. For example, you may notice:

  • Fever or chills
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Muscle or body aches
  • Headaches
  • Feeling tired
  • Sometimes vomiting or diarrhea (more common in children)

    • However, not everyone with the flu will have a fever.

    How Influenza Spreads

    Influenza spreads mainly through droplets when someone coughs, sneezes, or talks. These droplets can land in the mouths or noses of people nearby. Sometimes, you can get the flu by touching a surface with the virus and then touching your face. Because the flu spreads easily, knowing how to avoid the flu is key.

    Importance of Influenza Vaccines

    Getting a flu vaccine each year is the best way to lower your risk. Vaccines help your body build protection against the virus. According to the World Health Organization, flu vaccines prevent millions of illnesses and doctor visits every year. In addition, vaccines protect those around you, especially people who are at higher risk.

    Types of Flu Vaccines

    There are different types of flu vaccines. Your doctor can help you choose the best one. Common types include:

  • Standard flu shots (injected into the arm)
  • High-dose shots for older adults
  • Nasal spray vaccines (for certain age groups)

    • Each year, vaccines are updated to match the most common flu viruses.

    Everyday Tips to Prevent Influenza

    Besides vaccines, you can take simple steps to avoid the flu. For example, try these flu prevention tips:

  • Wash your hands often with soap and water
  • Use hand sanitizer if soap is not available
  • Avoid touching your eyes, nose, and mouth
  • Cover your mouth and nose when you cough or sneeze
  • Stay away from people who are sick
  • Clean and disinfect surfaces often
  • Stay home if you feel unwell
  • Eat healthy foods and get enough sleep

    • In crowded cities, these steps are even more important. Also, wearing a mask in public places can help reduce your risk.

    Who Should Get Vaccinated?

    Almost everyone over six months old should get a flu vaccine each year. However, it is especially important for:

  • Young children
  • Older adults (65 and above)
  • Pregnant women
  • People with chronic health problems
  • Healthcare workers

    • Getting vaccinated helps protect you and those around you.
