Overview

Colds, flu, and respiratory infections are among the most common reasons people visit a doctor — and knowing the difference between them can help you get the right treatment faster. While most colds resolve on their own within 7–10 days, influenza and bacterial respiratory infections can become serious without proper care. At Lemon-AID Medical Management, we offer same-day in-person and telehealth visits so you don't have to wait when you're feeling your worst.

Key Points

Colds are caused by viruses (most often rhinovirus) and do not respond to antibiotics.
Influenza (flu) comes on suddenly with fever, body aches, fatigue, and respiratory symptoms.
Bacterial infections like strep throat, sinusitis, and pneumonia may require antibiotic treatment.
COVID-19 symptoms overlap with flu — testing helps guide the right treatment plan.
Annual flu vaccination significantly reduces your risk of severe illness and hospitalization.

Signs & Symptoms

Runny or stuffy nose, sneezing, and sore throat
Fever, chills, and body aches (more common with flu)
Cough — dry or productive — and chest tightness
Fatigue and general feeling of being unwell
Shortness of breath or wheezing (seek care promptly)

Causes & Risk Factors

Viral infections: rhinovirus, influenza A/B, RSV, COVID-19, adenovirus
Bacterial infections: Streptococcus, Mycoplasma pneumoniae, Haemophilus influenzae
Weakened immune system from stress, poor sleep, or chronic illness
Close contact with infected individuals or contaminated surfaces
Seasonal changes that increase viral transmission

Treatment Options

1Rest, hydration, and over-the-counter symptom relief for mild viral illness

2Antiviral medications (oseltamivir/Tamiflu) for influenza when started within 48 hours

3Antibiotics prescribed only when a bacterial infection is confirmed

4COVID-19 antivirals (Paxlovid) for eligible high-risk patients

5Inhaled bronchodilators for wheezing or reactive airway symptoms

When to See a Doctor

See a provider same-day if you have a high fever (above 103°F), difficulty breathing, chest pain, symptoms lasting more than 10 days, or if you are immunocompromised, pregnant, or over age 65. Call 911 for severe shortness of breath or bluish lips.
