Abstract:
Influenza B is generally considered a mild respiratory virus, but this case demonstrates its potential for severe neurological complications in otherwise healthy individuals. We describe a 17-year-old male patient who developed encephalopathy and bilateral vocal cord paralysis, requiring intensive care and tracheostomy. The patient gradually recovered following supportive care and multidisciplinary rehabilitation. This report highlights the importance of recognizing rare complications during influenza outbreaks.

Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Respiratory Failure-III
Acute Respiratory Failure-V

Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
