Runny nose is the excess drainage of clear fluid or thick mucus produced by nasal and adjacent tissues and blood vessels in the nose.1 Sneezing is the sudden, forceful, uncontrolled burst of air through the nose and mouth caused by irritation to the mucus membranes of the nose or throat.2
What causes runny nose and sneezing in infants?
Both runny nose and sneezing in newborns and infants may be due to infections, such as the common cold or flu, or allergies, such as hay fever or dust allergies.2 Both are symptoms of rhinitis, which can have allergic or non-allergic aetiologies.3,4
Runny nose and sneezing as symptoms of Cows' Milk Allergy
Rhinitis symptoms (including runny nose and sneezing) can also be due to Cow’s Milk Allergy (CMA). For infants with CMA, rhinitis symptoms will manifest themselves rapidly following the ingestion of cows' milk.5
The majority of infants affected with CMA have at least two symptoms affecting at least two different organ systems.6,7 If you suspect non-IgE mediated CMA8,9,10, you can use the CoMiSS® tool11 to score the combination of their symptoms and assess the likelihood of CMA.
