Overview

Common risk factors in the development of acute viral nasopharyngitis are contact with an infected patient, going to daycare centers and lower body temperature.

Risk factors

More common risk factors

• Common risk factors for having acute viral nasopharyngitis
• Contact with flu patients especially if sitting in close proximity to the patient
• Going to daycare centers (for infants and children)
• Lower body temperature: there is controversy about the role of lower body temperature in causing viral nasopharyngitis but most of the evidence suggest that it is a risk factor.
• Allergic rhinitis or sinusitis.
• Immunosuppressed patients (HIV or hematologic malignancy)

Less common risk factors

• Less common risk factors include
• 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)
