ARNOLD AIR FORCE BASE, Tenn. -- Protecting yourself and maintaining preparedness during cold and flu season comes down to three key actions: getting your annual vaccines early, practicing rigorous hand and workspace hygiene, and isolating immediately if you develop symptoms.
Knowing the Difference: Cold Vs. Flu
Understanding whether you have a common cold or the flu is essential for choosing the right care and knowing when to stay home.
- Common Cold (Rhinovirus, Adenovirus): Typically presents with a gradual onset over 1-3 days. Symptoms are largely restricted to the upper respiratory tract – nasal congestion, runny nose, sneezing and mild sore throat. Systemic manifestations such as high fever and severe myalgia are rare in adults (National Institute of Allergy and Infectious Diseases).
- Influenza (Types A and B): Characterized by an abrupt onset within hours. Key markers include high fever (100°F -104°F), intense myalgia (muscle aches), pronounced fatigue, rigors (chills), and a dry cough. Flu related prostration and lethargy can persist for two weeks or longer (Centers for Disease Control and Prevention National Center for Immunization and Respiratory Diseases).
Everyday Prevention Strategies
Staying healthy during peak viral months requires consistent personal habits and environmental awareness.
- Vaccination: An annual flu shot remains the single most effective barrier against severe illness, hospitalization and downtime.
- Hand Hygiene: Wash hands thoroughly with soap and water for at least 20 seconds, especially after coughing, sneezing or touching communal surfaces. Alcohol-based hand sanitizers with at least 60% alcohol are a solid alternative when water is unavailable.
- Clean Shared Workspaces: Frequently disinfect high-touch surfaces such as keyboards, desks, phones, radios and door handles to break the chain of transmission.
- Hydration and Recovery: Maintain adequate sleep, proper nutrition and steady hydration to keep your immune system operating at full strength.
What to Do If You Get Sick
- Mild symptoms with no fever: You can generally continue working but increase your hand hygiene and consider wearing a mask in close quarters to protect colleagues.
- Fever, chills and full body aches: Isolate immediately. Stay home until you are fever free for at least 24 hours without using fever-reducing medications.
- Early antiviral window: If you suspect the flu, consult a healthcare provider within the first 48 hours of symptom onset, as antiviral medications are most effective when started as early as possible.
- Severe warning signs: Seek urgent medical attention if you have trouble breathing, persistent chest pain, confusion or a sudden relapse after initially improving.
Things to Avoid
- Toughing it out at work: Coming into the office sick spreads pathogens across the office and reduces productivity all around.
- Demanding antibiotics: Colds and the flu are caused by viruses, not bacteria. Antibiotics will not cure viral infections and can cause unnecessary side effects.
- Returning too early: Returning to work before your fever completely resolves risks infecting others and can lead to a secondary bacterial infection.
