Overview
Common risk factors for the development of acute viral nasopharyngitis are contact with an infected patient, going to daycare centers.
Risk factors
More common risk factors
Common risk factors for acute viral nasopharyngitis include:[1]
- Contact with infected persons patients especially if sitting in close proximity to the patient
- Going to daycare centers (for infants and children)
- Allergic rhinitis or sinusitis
- Immunosuppressed patients (HIV or hematologic malignancy)
Exposure to Cold Weather
- Despite the fact that most common colds occur in fall and winter, there is no proven assocoiation between cold exposure or chilling and common colds.[2][3]
- With respect to the causation of cold-like symptoms, researchers at the Common Cold Centre at the Cardiff University conducted a study to "test the hypothesis that acute cooling of the feet causes the onset of common cold symptoms."[4] The study measured the subjects' self-reported cold symptoms, and belief they had a cold, but not whether an actual respiratory infection developed. It concludes that the onset of common cold symptoms can be caused by acute chilling of the feet, but that "further studies are needed to determine the relationship of symptom generation to any respiratory infection."
Less common risk factors
Less common risk factors include[5]
- Pregnant women are at increased risk of having common cold for up to 2 weeks after delivery. On the opposite, breastfeeding decreases the risk of having common cold
- Old age > 65 years
- Morbid obesity (BMI > 35)
