Influenza is spreading rapidly across the United States, with over half the country reporting high or very high flu activity. Experts warn cases will continue to rise, particularly among children, but also affecting younger and older adults. While avoiding the flu entirely can be difficult, recognizing early symptoms and taking swift action can significantly reduce severity and prevent complications.
Recognizing The First Signs
The flu typically strikes suddenly, unlike a common cold which develops gradually. Abrupt fever, headache, and body aches are classic indicators. According to Dr. Madison Szar, pediatrician at Bluebird Kids Health, “For most people, all ages, the classic symptoms are going to be a pretty abrupt onset of fever, headaches, body aches are really common.” Chills, cough, runny nose, and sore throat often follow quickly.
Children may experience additional gastrointestinal symptoms like stomach pain, nausea, vomiting, or loss of appetite. This is because the flu manifests differently in younger patients.
How Quickly Does The Flu Hit?
The flu doesn’t creep up on you. Dr. Robert Hopkins, medical director of the National Foundation for Infectious Diseases, explains, “People will often be able to tell you within the minute or the hour when their symptoms started.” This swift onset is a key distinction from other respiratory illnesses. If symptoms appear suddenly and intensely, it’s likely influenza.
When To See A Doctor
Early intervention is crucial. Antiviral medications are most effective within the first 48 hours of symptom onset, especially for high-risk patients such as those with asthma or COPD.
Pay attention to these warning signs:
- Recurring fever: A fever that subsides with medication only to return is a red flag. It could indicate a secondary bacterial infection like pneumonia.
- Severe dehydration: Lightheadedness, dizziness, or infrequent urination require immediate medical attention. The flu can quickly deplete fluids.
Prevention and Treatment
If you suspect the flu, stay home to prevent spreading the virus. Prioritize hydration by drinking water, herbal tea, or electrolyte solutions. Over-the-counter fever reducers and pain relievers can manage symptoms, while decongestants and cough medicine may provide relief for adults. For children over one year old, honey can soothe a cough.
The most effective defense remains vaccination. Even if you contract the flu after vaccination, symptoms will likely be milder, and the risk of hospitalization or severe illness decreases. The vaccine is still beneficial even late in the season. Flu deaths, particularly among children, have reached record highs this season, underscoring the vaccine’s importance.
Despite misinformation, the flu vaccine remains the most impactful measure we can take to minimize the virus’s impact on everyone aged six months and older.
Getting vaccinated now allows approximately two weeks for your body to build a protective immune response. Don’t delay, especially as flu activity continues to climb.
