Even though Arizona is known for sunshine instead of snow, cold and flu season still hits hard, especially during the winter months when more people are indoors, traveling, and gathering for the holidays. If you or a family member starts feeling sick, it can be hard to tell when it’s just a mild bug… and when it’s something that needs urgent or emergency care.
At Fountain Hills Emergency Room & Medical Center, we’re here to help you understand the signs, stay safe, and know exactly where to go when symptoms take a turn.
Why Cold & Flu Season Gets Worse in Arizona
You might think warm climates avoid winter illnesses, but in the Valley, we see a spike every year because:
- People spend more time indoors together
- Dry desert air irritates the throat and sinuses
- Holiday travel brings new viruses into the state
- Allergies can mimic or worsen cold symptoms
It’s the perfect storm for germs to spread and for symptoms to surprise you.
Common Cold vs. Flu: What’s the Difference?
Both illnesses can make you feel miserable, but flu symptoms usually hit harder and faster.
Cold Symptoms
- Stuffy or runny nose
- Mild cough
- Sore throat
- Low-grade fever or no fever
- Fatigue
Flu Symptoms
- High fever
- Intense body aches
- Severe fatigue
- Chills and sweats
- Dry, persistent cough
- Headache
If symptoms come on suddenly and knock you off your feet, it’s more likely the flu.
When Cold or Flu Symptoms Get Worse
Most people recover with rest, fluids, and over-the-counter medication.
But sometimes, symptoms get stronger instead of better.
Here are red flags you should never ignore:
❗ Severe or Worsening Fever
- Fever over 103°F in adults
- Any fever lasting more than 3 days
- Fever returning after you started feeling better
❗ Trouble Breathing
- Shortness of breath
- Wheezing
- Rapid breathing
- Tightness in the chest
(This is especially important for people with asthma, COPD, or heart conditions.)
❗ Persistent or Severe Cough
A cough that gets worse, produces thick mucus, or causes chest pain could signal:
- Pneumonia
- Bronchitis
- Asthma flare-up
- RSV
❗ Dehydration
Watch for:
- Dry mouth
- Dark urine
- Dizziness
- Minimal sweating or tears
❗ Symptoms in High-Risk Individuals
Seek prompt care if symptoms worsen in:
- Young children
- Adults over 65
- People with chronic conditions (diabetes, heart issues, asthma)
- Those with weakened immune systems
When to Visit Urgent Care
Urgent Care is a great choice when symptoms are uncomfortable but not life-threatening.
Come in for:
- Cough, congestion, sore throat
- Ear pain or sinus pressure
- Fever that isn’t extremely high
