Flu Activity Is Rising: What You Need to Know to Stay Protected

Why Flu Activity Is Rising Right Now

Several factors contribute to increased flu activity during this time of year:

1. Seasonal Weather Changes

Colder temperatures lead to more time indoors, creating ideal conditions for flu viruses to spread.

2. Weakened Immunity After the Holidays

Stress, travel, disrupted sleep, and poor nutrition during holiday periods can temporarily weaken immune defenses.

3. Lower Vaccination Rates in Some Groups

Delayed or skipped flu vaccinations can allow the virus to circulate more widely in communities.

What Is Influenza?

Influenza is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. It spreads primarily through droplets when infected individuals cough, sneeze, or talk.

Common Flu Symptoms

• Fever or chills

• Cough and sore throat

• Muscle or body aches

• Fatigue

• Headache

• Runny or congested nose

Symptoms can range from mild to severe and may last from several days to over a week.

Who Is Most at Risk When Flu Activity Is High?

Certain populations face a higher risk of complications during peak flu activity, including:

• Older adults

• Young children

• Pregnant individuals

• People with chronic conditions (asthma, diabetes, heart disease)

• Individuals with weakened immune systems

For these groups, prevention is especially important.

How to Protect Yourself as Flu Activity Increases

💉 Get the Flu Vaccine

Vaccination remains the most effective way to reduce the risk of flu-related illness, hospitalization, and complications. Even if you get the flu after vaccination, symptoms are often milder.

🧼 Practice Good Hygiene

• Wash hands frequently with soap and water

• Use alcohol-based hand sanitizers when needed

• Avoid touching your face

😷 Stay Home When Sick

Limiting contact with others helps slow the spread and protects vulnerable populations.

🛌 Support Your Immune System

• Prioritize quality sleep

• Eat nutrient-dense foods

• Stay hydrated

• Manage stress levels

How Flu Vaccines Help During High Activity Periods

Flu viruses change every year, which is why vaccines are updated annually. Vaccination helps:

• Reduce overall infection rates

• Lower severity of illness

• Protect communities through reduced transmission

Getting vaccinated—even during peak flu season—can still provide meaningful protection.

When to Seek Medical Care

Seek medical advice if flu symptoms:

• Worsen rapidly

• Last longer than expected

• Include difficulty breathing or chest pain

• Occur in high-risk individuals

Early care can prevent complications.

Flu Prevention Beyond Vaccines

While vaccination is key, it works best alongside daily habits:

• Wearing masks in crowded indoor settings when flu activity is high

• Improving indoor ventilation

• Disinfecting frequently touched surfaces

Small actions can significantly reduce exposure risk.

The Bottom Line

With flu activity rising, staying informed and proactive is essential. Vaccination, good hygiene, and supportive lifestyle habits remain the most effective tools for protecting yourself and others.

Seasonal influenza is common—but serious outcomes are preventable when communities act early and consistently.
