Every year, influenza—commonly called the flu—affects millions of people, causing missed work and school, disrupted family routines, and, for some individuals, serious health complications. While many people assume the flu is “just a bad cold,” influenza is a highly contagious viral infection that can lead to pneumonia, dehydration, worsening of chronic medical conditions, hospitalization, and even life-threatening complications.
Knowing how to recognize flu symptoms early, understanding when to get tested, and seeking prompt treatment can make a significant difference in your recovery. At UNI Urgent Care, our team provides convenient evaluation, flu testing, treatment recommendations, and preventive services to help patients recover safely while reducing the spread of illness throughout the community.
Whether you’re experiencing sudden fever and body aches or wondering if it’s time for a flu shot, this guide explains everything you need to know. For more health tips and seasonal updates, be sure to check our blogs.
What Is the Flu?
Influenza is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. Unlike the common cold, the flu usually comes on suddenly and often causes more severe symptoms. According to the Centers for Disease Control and Prevention (CDC), influenza spreads primarily through respiratory droplets released when someone coughs, sneezes, talks, or even breathes in close proximity to others. It can also spread when someone touches contaminated surfaces and then touches their eyes, nose, or mouth.

Most healthy adults recover within one to two weeks, but infants, older adults, pregnant women, and individuals with chronic medical conditions have a higher risk of serious complications.
Common Flu Symptoms
Recognizing the symptoms early helps you seek treatment sooner, especially if antiviral medication may be beneficial.
Sudden Fever
One of the hallmark signs of influenza is a rapid onset of fever. Many patients develop temperatures above 100.4°F (38°C), often accompanied by chills.
Not everyone develops a fever, but when it occurs alongside other symptoms, influenza becomes more likely.
Severe Body Aches
The flu frequently causes widespread muscle pain and joint aches that make even simple daily activities feel exhausting.
Patients often describe feeling like they “got hit by a truck.”
Persistent Cough
Unlike the mild cough of many colds, flu-related coughing can become persistent, dry, and uncomfortable.
Fatigue
Extreme tiredness is one of the defining characteristics of influenza.
Many people need several days of bed rest because of overwhelming fatigue.
Headache
Moderate to severe headaches commonly occur alongside fever and muscle aches.
Sore Throat
A sore throat may appear early in the illness and often accompanies coughing.
Runny or Stuffy Nose
Although congestion is more common with colds, many influenza patients also experience nasal symptoms.
Chills and Sweating
Alternating chills and sweating frequently accompany fever during the first few days.
Loss of Appetite
Many people notice decreased appetite while their body fights the infection.
Why Early Flu Testing Matters
Testing helps confirm whether influenza is causing your symptoms rather than another viral illness. Medical guidelines from the National Institutes of Health (NIH) emphasize the importance of timely diagnostics.
At our clinic, flu testing may be recommended when:
-
Symptoms began recently
-
You are at high risk for complications
-
You may benefit from antiviral medication
-
Your employer or school requires testing
-
Symptoms could represent COVID-19, RSV, or another respiratory illness
Rapid flu testing often provides results within minutes, helping guide treatment decisions during your visit.
When Antiviral Treatment Can Help
Many people assume antibiotics treat the flu, but influenza is caused by a virus—not bacteria. Detailed resources from the Cleveland Clinic explain that certain prescription antiviral medications may help:
Shorten Illness
When started within the first 48 hours of symptoms, antivirals may reduce illness duration by approximately one day.
Reduce Severity
Patients often experience milder symptoms and fewer complications.
Lower Hospitalization Risk
Individuals with chronic medical conditions may benefit from early treatment that reduces the likelihood of severe illness.
Not everyone requires antiviral medication, but our providers evaluate each patient individually to determine whether treatment is appropriate.
Supportive Treatment for Flu Recovery
Even without antiviral medication, supportive care helps your body recover.
Stay Hydrated
Fever causes fluid loss.
Drink:
-
Water
-
Electrolyte beverages
-
Clear soups
-
Herbal tea
Avoid excessive alcohol and dehydration.
Get Plenty of Rest
Your immune system functions best when your body has adequate sleep.
Avoid strenuous exercise until you’ve recovered.
Reduce Fever Safely
Over-the-counter medications may help lower fever and relieve aches when taken as directed.
Always follow dosage instructions and consult a healthcare provider regarding children.
Eat Nutritious Foods
Even with decreased appetite, consuming nutritious foods supports recovery.
Choose easy-to-digest meals if your stomach feels unsettled.
Signs You Should Visit Urgent Care
While many cases improve with home care, certain symptoms deserve prompt medical evaluation. If you need immediate assistance, find one of our practitioner teams near you via our Locations page.
High Fever That Doesn’t Improve
Persistent high fever lasting several days may indicate complications.
Difficulty Breathing
Shortness of breath, rapid breathing, or chest tightness should never be ignored.
Chest Pain
Chest discomfort during influenza may require immediate evaluation.
Severe Dehydration
Seek care if you’re unable to keep fluids down or experience:
-
Dizziness
-
Confusion
-
Very dark urine
-
Dry mouth
-
Little urination
Symptoms That Improve Then Suddenly Return
Feeling better before suddenly developing worsening fever and cough could suggest a secondary bacterial infection such as pneumonia.
Persistent Vomiting
Frequent vomiting increases dehydration risk and deserves medical attention.
Confusion or Extreme Drowsiness
Mental status changes require urgent evaluation.
High-Risk Patients
Visit urgent care sooner if you:
-
Are over 65
-
Are pregnant
-
Have asthma
-
Have COPD
-
Have diabetes
-
Have heart disease
-
Have weakened immunity
Our medical team can evaluate your symptoms, perform testing when appropriate, recommend treatment, and determine whether additional care is needed.
Flu Complications You Should Know About
Although many people recover completely, influenza sometimes leads to complications.
Potential complications include:
-
Pneumonia
-
Bronchitis
-
Sinus infections
-
Ear infections
-
Worsening asthma
-
COPD flare-ups
-
Heart complications
-
Dehydration
Early evaluation helps identify problems before they become more serious.
When Should You Get a Flu Shot?
Vaccination remains the most effective way to reduce your risk of influenza.
Best Time
Most people should receive their flu shot during September or October before flu activity peaks.
However, vaccination later in the season still provides protection if flu viruses continue circulating.
Annual Vaccination Matters
Influenza viruses change every year.
That’s why an updated vaccine is recommended annually.
Who Should Get Vaccinated?
The CDC recommends yearly flu vaccination for nearly everyone six months of age and older, with very few exceptions.
Vaccination is especially important for:
-
Older adults
-
Young children
-
Pregnant individuals
-
Healthcare workers
-
Individuals with chronic medical conditions
-
Caregivers of vulnerable family members
Our clinic offers flu vaccinations to help patients protect themselves and those around them throughout flu season.
Ways to Avoid Getting the Flu
Preventing influenza involves multiple healthy habits working together.
Wash Your Hands Frequently
Soap and water remain one of the best defenses.
Wash for at least 20 seconds, especially after:
-
Coughing
-
Sneezing
-
Using public transportation
-
Visiting public places
Use Hand Sanitizer
Alcohol-based sanitizer works well when soap isn’t available.
Avoid Touching Your Face
Viruses often enter through the eyes, nose, and mouth.
Cover Your Cough
Use your elbow or a tissue instead of your hands.
Dispose of tissues immediately.
Stay Home When Sick
Remaining home while contagious protects coworkers, classmates, friends, and family.
Generally, patients should remain home until fever-free for at least 24 hours without fever-reducing medication.
Clean Frequently Touched Surfaces
Regularly disinfect:
-
Phones
-
Keyboards
-
Door handles
-
Countertops
-
Light switches
Support Your Immune System
Healthy lifestyle habits help your immune system function effectively.
Aim for:
-
Regular sleep
-
Balanced nutrition
-
Physical activity
-
Stress management
-
Adequate hydration
When Should You Get Tested?
Testing isn’t necessary for every illness, but evaluation becomes especially helpful when:
Symptoms Started Recently
Early diagnosis allows providers to determine whether antiviral treatment may help.
You’re at High Risk
Individuals with underlying medical conditions benefit from prompt assessment.
Symptoms Are Severe
Difficulty breathing, dehydration, or worsening illness deserve evaluation.
You Need Documentation
Schools, employers, or travel requirements sometimes require confirmation of illness.
You Aren’t Sure Whether It’s Flu
COVID-19, RSV, strep throat, pneumonia, and other respiratory illnesses may produce similar symptoms.
Testing helps identify the cause.

Frequently Asked Questions
How long does the flu usually last?
Most people begin improving within five to seven days, although fatigue and coughing may continue for several weeks.
Can antibiotics cure the flu?
No. Antibiotics treat bacterial infections, not influenza viruses. They should only be used when prescribed for a confirmed or suspected bacterial infection.
How soon should I seek treatment?
Ideally, patients should be evaluated within the first 48 hours after symptoms begin, especially if they are at higher risk for complications or may benefit from antiviral medication.
Can I still get the flu after receiving a flu shot?
Yes, but vaccination often reduces the severity of illness and lowers the risk of hospitalization and serious complications.
Is the flu contagious?
Yes. People can spread influenza beginning about one day before symptoms appear and for several days afterward.
Should I go to work or school with the flu?
No. Stay home until you have been fever-free for at least 24 hours without using fever-reducing medication.
