Antimicrobial resistance with a focus on antibacterial, antifungal, antimalarial, and antiviral drugs resistance, its threat, global priority pathogens, prevention, and control strategies: a review

Abstract

Antimicrobial resistance (AMR) poses a significant global health threat by diminishing the effectiveness of once-powerful antimicrobial agents, leading to higher rates of illness and death, along with escalating healthcare costs. While bacterial resistance is a primary concern, resistance is also increasing against antifungal, antiparasitic, and antiviral drugs. Many of the last-resort drugs are becoming less effective due to AMR. Projections indicate that by 2050, AMR could cause up to 10 million deaths annually, making it the leading cause of death worldwide, a situation that could result in a post-antibiotic era with substantially increased morbidity and mortality. This review aims to raise awareness about the dangers of AMR and its potential to become a silent global pandemic. It begins by examining antimicrobial drugs, followed by a discussion on AMR, focusing on resistance to antibacterial, antifungal, antimalarial, and antiviral drugs, along with its effects on health, and the economy, and prioritized global pathogens. Finally, it explores preventive measures and innovative strategies to combat AMR.
