Can an Upper Respiratory Infection Become Severe?
Upper respiratory infections (URIs), commonly caused by viruses like rhinoviruses or coronaviruses, typically manifest as mild illnesses with symptoms such as a runny nose, sore throat, cough, and congestion. However, while most cases resolve on their own within 7 to 10 days, certain infections can escalate to more serious conditions. In some individuals, particularly those with weakened immune systems, chronic health issues, or young children, a URI may develop into complications such as sinus infections, ear infections, or even lower respiratory tract infections like bronchitis or pneumonia. The severity often depends on the underlying health of the individual and the specific pathogen involved.
In rare instances, untreated or prolonged symptoms of a URI can lead to significant health issues, including secondary bacterial infections or exacerbations of chronic respiratory diseases like asthma or chronic obstructive pulmonary disease (COPD). Warning signs of complications may include high fever, difficulty breathing, persistent chest pain, or worsening symptoms beyond the typical duration of a URI. If such symptoms occur, prompt medical evaluation is crucial to prevent further complications.
