LOS ANGELES (Jan. 22, 2025) -- While flu season in the U.S. typically runs from October through March, California flu season peaks in January and February. The Cedars-Sinai 海角社区room spoke with , pediatric infectious disease specialist at , about what to expect during the ongoing virus season.
What type of flu activity are we seeing in California this year and what are the symptoms?
As of early January, flu activity in California has been increasing and is comparable to levels observed at this time last year. Influenza (flu) typically presents with sudden onset of high-grade fever, accompanied by body aches, chills, headache, nasal congestion, runny nose and occasionally sore throat or fatigue.
When should you see a doctor?
The course of the flu can vary from person to person, but if you're experiencing prolonged fevers lasting three to five days, worsening cough or shortness of breath, signs of dehydration, or if you have exacerbation of underlying respiratory conditions such as asthma, it may be a good idea to check in with your primary care provider. Additionally, if you develop a new fever after initially recovering from the flu, be aware of the possibility of a secondary bacterial infection, such as a pneumonia, which would require medical attention.
Is it too late to get the flu vaccine?
While getting the flu shot earlier in the season is ideal, vaccination at any point during the flu season can still provide significant protection. 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.
Each year, the flu vaccine is designed to target the most likely circulating strains. Although the vaccine may not be a perfect match for all strains, it provides partial immunity, which is highly beneficial in preventing severe illness.
What is norovirus and how is it affecting Californians?
, often referred to as the “stomach flu,” is a highly contagious virus that causes gastroenteritis. We see symptoms including nausea, vomiting, diarrhea, abdominal cramping and occasionally low-grade fever. Norovirus is one of the leading causes of foodborne illness.
What can people do to stay healthy during virus season?
The advice is always the same. We need to be really mindful of our hand washing and being careful among high-risk individuals. Wearing a mask is of utmost importance because of the fires but also 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.
