Streptococcus pyogenes Pneumonia: A Rare and Severe Presentation in a Patient With Asthma.

Pneumonia is a common respiratory infection typically caused by pathogens such as Streptococcus pneumoniae , Haemophilus influenzae , and Staphylococcus aureus . It is characterized by inflammation and infection in the lung parenchyma, often presenting with symptoms such as cough, fever, and difficulty breathing. Empyema, on the other hand, is a severe complication of pneumonia marked by the accumulation of pus in the pleural cavity. Streptococcus pyogenes ( S. pyogenes ), also known as group A Streptococcus (GAS), is a bacterium that can cause various infections, including pharyngitis and skin infections. In rare cases, it can lead to community-acquired pneumonia. In our case report, we describe a 32-year-old female with a history of mild persistent asthma who contracted influenza B virus, eventually developing pneumonia caused by GAS, S. pyogenes .
