Influenza

Influenza

Influenza (the flu) is a highly contagious respiratory illness caused by influenza viruses. It spreads mainly through droplets when an infected person coughs, sneezes, or talks, and can also be picked up from contaminated surfaces. Unlike the common cold, influenza usually comes on suddenly and can cause fever, chills, body aches, sore throat, cough, headache, and fatigue.

Most healthy people recover in one to two weeks, but the flu can lead to serious complications such as pneumonia, bronchitis, or worsening of chronic conditions like asthma, diabetes, and heart disease. Children, older adults, pregnant women, and those with weakened immune systems are at higher risk for severe illness and hospitalization.

Because influenza viruses change frequently, annual vaccination is recommended for everyone six months and older. The flu vaccine reduces the risk of infection, lowers the severity of illness if you do get sick, and helps protect vulnerable people in the community.

Preventing influenza also involves good hygiene practices: frequent handwashing, covering coughs and sneezes, staying home when ill, and avoiding close contact with sick individuals. Antiviral medications may be prescribed for people at higher risk or those who develop complications, especially if started early.

Influenza is more than “just a bad cold.” It is a serious disease that causes millions of illnesses and hundreds of thousands of hospitalizations each year in the United States. Getting vaccinated and practicing healthy habits are the best ways to protect yourself and others during flu season.

Why the Flu Vaccine Is So Important

Maybe you’ve had the flu before and thought it was “just a bad cold.” Maybe you’ve been lucky enough to avoid it and figure you don’t need a vaccine. Whatever the case, influenza is more than an inconvenience — it’s a serious viral infection that can impact your health, your family, and your community. Dr. Michael N. Newton and his staff work with patients to reduce their risk of flu complications through prevention and vaccination.

The link between influenza and chronic health problems

The flu isn’t just about fever and body aches. For people with asthma, heart disease, diabetes, or other chronic conditions, influenza can trigger dangerous complications. The infection can lead to pneumonia, worsen existing illnesses, and in some cases, become life-threatening.

Even in otherwise healthy people, the flu can cause days to weeks of illness, missed work or school, and lingering fatigue. Because the virus spreads easily, one person’s infection can quickly ripple through families, workplaces, and entire communities.

Children, older adults, and people with weakened immune systems are especially vulnerable — and protecting them often depends on those around them getting vaccinated.

How to protect yourself from influenza

If you want to lower your risk of getting seriously ill, the flu vaccine is your best defense. Here’s what you can do:

• Get your flu shot every year. The flu virus changes, so vaccines are updated annually.

• Wash your hands often and avoid close contact with people who are sick.

• Cover coughs and sneezes to prevent spreading germs.

• Stay home when you’re sick to protect others.

• Maintain overall health with exercise, good sleep, and nutrition to support your immune system.

Even if you still get the flu after vaccination, the illness is often shorter and less severe — and you’re much less likely to be hospitalized.

Common flu symptoms and related complications

Flu symptoms often come on suddenly and may include:

• Fever and chills

• Body aches

• Sore throat

• Cough

• Fatigue

In some cases, influenza can lead to complications such as pneumonia, bronchitis, or worsening of chronic illnesses like asthma and COPD.

If you develop flu-like symptoms, especially if you’re in a high-risk group, medical care and antiviral medications may help shorten recovery time and prevent complications.

Protect yourself — and your community

The flu vaccine isn’t just about avoiding a week in bed. It’s about protecting your lungs, your long-term health, and the people around you. By getting vaccinated every year, you help reduce the spread of influenza and keep your community healthier during flu season.
