Influenza and Aging: Clinical Manifestations, Complications, and Treatment Approaches in Older Adults.

Influenza, a highly contagious respiratory viral illness, poses significant global health risks, particularly affecting older and those with chronic health conditions. Influenza viruses, primarily types A and B, are responsible for seasonal human infections and exhibit a propensity for antigenic drift and shift, contributing to seasonal epidemics and pandemics. The severity of influenza varies, but severe cases often lead to pneumonia, acute respiratory distress syndrome, and multiorgan failure.

Mycobacterium chimaera infection masquerading as a lung mass in a healthcare worker.

, a nontuberculous mycobacterium, is a member of the complex (MAC). This microorganism has recently gained significant notoriety for its association with outbreaks in patients exposed to contaminated heater -cooler devices used during open heart surgeries. We report a case of pulmonary infection in a healthcare worker who presented with cough, low grade fever and weight loss with evidence of a lung mass that was initially thought to be a tumor on CT scan imaging.
