In clinical settings, pneumonia patients exhibit varying accompanying symptoms depending on the type of pneumonia. Particularly in very young infants, the early symptoms might primarily include nasal congestion, runny nose, sneezing, and even fever, without obvious coughing symptoms. In some newborns, pneumonia can be diagnosed through auscultation at this stage. In adults, certain types of pneumonia, such as those caused by viral infections, may not receive timely and effective anti-infective or antiviral treatment initially. In these cases, the condition can worsen and spread, leading to pneumonia, with some patients also experiencing symptoms of a runny nose. Of course, conditions like most cases of mycoplasma pneumonia, bacterial pneumonia, and lung abscesses that cause pulmonary inflammation usually do not involve a runny nose. Therefore, in clinical practice, if pneumonia is accompanied by a runny nose, it is usually due to specific circumstances of the illness.
