Superinfection

Superinfection occurs when a person is re-infected with a pathogen they had previously been infected with, due to the emergence of a related or distinct strain that has become more resistant or virulent. It has serious implications for disease management and public health, as it increases the risk of potential outbreaks and exacerbates existing health problems. Superinfection is becoming more common with the rise of antibiotic resistance in bacteria and viruses, the increased susceptibility of immunocompromised individuals, and the growing prevalence of emerging and re-emerging infectious diseases. In addition, superinfection can complicate treatment regimens, leading to more severe and costly treatments. Understanding the causes and effects of superinfection is vital for developing effective strategies for preventing and controlling disease.
