Abstract:
We describe a case of an 80-year-old man with COVID-19 and Legionella bacterial co-infection who initially presented to hospital with fever, respiratory symptoms, and diarrhea with radiographic evidence of atypical infection. His initial nasopharyngeal swab was negative; however, a subsequent swab was positive. A Legionella urinary antigen test was positive for Legionella pneumophilia serogroup 1 antigen. Despite a low prevalence of bacterial co-infection in patients with COVID-19, a large number of patients receive antimicrobial therapy. Based on clinical context, a high index of suspicion is warranted for both bacterial and viral infectious processes during the COVID-19 pandemic; this will help to ensure that appropriate antimicrobial therapy is used.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Pneumonia I: Introduction
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....
