Flu and Stomach Bugs Are Spreading Fast—Are You Prepared?

Flu season is in full swing, making it more important than ever to take steps to protect yourself and your loved ones.

Dr. Priya Soni, a pediatric infectious disease specialist at Cedars-Sinai Guerin Children’s Health Center in Los Angeles, shares what to expect this season and how to stay healthy.

What type of flu activity are doctors seeing this year, and what are the symptoms?

Flu season typically runs from October through March, with peak activity in January and February. This year’s flu activity is similar to last season, with cases increasing across the country.

The flu usually comes on suddenly and can cause:

• High fever

• Chills

• Body aches

• Headache

• Fatigue

• Nasal congestion

• Sore throat

When should you see a doctor for the flu?

Most flu cases can be managed at home, but certain symptoms may require medical attention.

Seek medical care if you experience any of the following:

• A fever lasting more than three to five days

• Worsening cough or shortness of breath

• Signs of dehydration (dizziness, dry mouth, less frequent urination)

• A new fever after initial recovery, which may signal a secondary bacterial infection like pneumonia

Is it too late to get the flu vaccine?

Nope! It’s not too late to get vaccinated.

"The flu vaccine reduces the severity of illness and lowers the risk of complications, especially for high-risk individuals such as young children, pregnant women, the elderly and those with chronic medical conditions," Soni said in a news release.

Each year’s vaccine targets the most common flu strains, and even if it’s not a perfect match, it still provides partial immunity to help prevent severe illness and hospitalization.

What is norovirus, and how is it spreading?

Norovirus, often called the "stomach flu," is a highly contagious virus that causes nausea, vomiting, diarrhea and stomach cramps. Occasionally, people get a low-grade fever, too. It spreads through contaminated food, water and surfaces and is a leading causes of foodborne illness.

What can people do to stay healthy during virus season?

To reduce your risk of flu, norovirus and other seasonal viruses, take common-sense precautions.

"We need to be really mindful of our hand washing and being careful among high-risk individuals," Soni said. "Wearing a mask is of utmost importance … to prevent the spread of respiratory infections in this critical time period during the winter. Additionally, remember to listen to your body and stay home if you’re unwell."
