👉 Combo-infection refers to the simultaneous or sequential infection of a host by two or more pathogens, such as bacteria, viruses, or parasites. This phenomenon can lead to more severe disease outcomes compared to single infections because it can result in complex interactions between the pathogens, enhancing their virulence or altering the host's immune response. For example, a bacterial infection might weaken the host's defenses, making it easier for a secondary viral infection to take hold. Combo-infections are particularly concerning in immunocompromised individuals, where multiple pathogens can exploit the weakened state, leading to more aggressive and harder-to-treat illnesses. Understanding combo-infections is crucial for developing effective treatment strategies and public health interventions.
