IntermtnMedCtr - When a common cold is something more than a cold

Short Summary

Main recommendation: Dr. Blagev explains a common cold is usually a self-limited viral illness that resolves in about a week with supportive care, and recommends seeing a doctor if symptoms are severe, persist beyond a week or two, or worsen. Dr. Denitza Blagev of Intermountain Medical Center explains that a cold can make you more vulnerable to a secondary bacterial infection such as bronchitis or pneumonia.

Key Points

• A common cold is usually caused by a virus and typically brings a runny nose, mild fatigue, cough, and feeling run down.
• A cold can predispose you to a bacterial infection on top of it, because the virus damages airway defenses, much like a cut in the skin lets bacteria in.
• According to Dr. Blagev, pneumonia is an infection of the lung that can also be caused by influenza through lung damage and inflammation, and it usually needs treatment, sometimes including antivirals.
• Severity of symptoms matters most, especially in someone with an existing lung problem who is severely short of breath.
• Improvement over about a week, even if not fully resolved, indicates recovery is on track.

Details Worth Noting

• Concrete instructions: Give a cold about a week and monitor it. If it is getting better, even if not fully gone, you are heading in the right direction. Seek a doctor if fevers increase, mucus coughing worsens, or symptoms persist beyond a week or two. Seek evaluation promptly for severe fever, severe shortness of breath, or significant pain with each deep breath. Anyone with an existing lung problem who is severely short of breath should be evaluated regardless of how long symptoms have lasted.
• Pneumonia usually requires an antibiotic, and because influenza can also cause it, antivirals may be needed as well.
• The video stresses that pneumonia has a significant complication rate, which is why it is evaluated and treated rather than left alone.
• Dr. Blagev's skin analogy: intact skin blocks bacteria, but a cut makes infection easier, and a viral airway infection works similarly.
• This is general information from the video, not individualized medical advice; consult a clinician for personal decisions.

Bottom Line

Most colds resolve on their own in about a week, but worsening symptoms, severe breathing trouble, or persistent illness are signs to see a doctor promptly.
