Acute Upper Respiratory Infections

Acute upper respiratory infections (URIs) represent a common group of illnesses affecting the upper respiratory tract, including the nose, throat, and sinuses. These infections are typically caused by viruses, such as rhinoviruses, coronaviruses, influenza viruses, and adenoviruses. Common symptoms of acute URIs include nasal congestion, runny nose, sneezing, sore throat, coughing, and sometimes fever. The majority of acute URIs are self-limiting and resolve without specific medical treatment. Supportive care, including rest, hydration, and over-the-counter medications for symptom relief, is often recommended. Antiviral medications may be prescribed in certain cases, such as influenza infections. Antibiotics are not effective against viral URIs and are reserved for bacterial infections, which are less common. Preventive measures for acute URIs include practicing good hand hygiene, avoiding close contact with infected individuals, and getting vaccinated against influenza. While these infections are usually mild, they can cause more severe complications in certain populations, such as the elderly, young children, or individuals with underlying health conditions.
