Final answer:
The inflammation of the larynx usually associated with common cold or influenza syndromes, caused by viruses, is known as laryngitis.
Step-by-step explanation:
Inflammation of the larynx that is usually associated with the common cold or influenza syndromes and caused almost exclusively by viruses is known as laryngitis. This condition often leads to symptoms such as hoarseness or loss of voice, difficulty speaking, a sore throat, and sometimes fever or a cough. While laryngitis itself is a symptom of an infection in the upper respiratory tract, it can be part of a broader spectrum of illnesses caused by viral infections which commonly lead to various forms of respiratory inflammation. Due to its viral nature, it is typically self-limiting and should resolve within a week or two without the need for antibiotics. However, supportive treatments such as rest, hydration, and over-the-counter medications can help alleviate symptoms.
