What is Antimicrobial Resistance?

Antimicrobial resistance (AMR) refers to the ability of microorganisms, such as bacteria, viruses, fungi, and parasites, to develop resistance or become immune to those that are designed to kill or inhibit their growth.

Antimicrobial Resistance Statistics – Antimicrobial resistance (AMR) poses a significant global challenge, leading to increased mortality, healthcare costs, and economic burden.

Countries worldwide including Brazil, are grappling with the rise of resistant pathogens in healthcare settings.

The prevalence of resistant strains such as MRSA, ESBL-producing bacteria, and MDR-TB in Brazil highlights the urgent need for robust interventions to combat AMR.

Efforts to improve infection control practices, promote appropriate antimicrobial use, and enhance surveillance systems are crucial in mitigating the impact of AMR and safeguarding public health.

Continued collaboration and implementation of comprehensive strategies are essential to address this growing threat.
