Antimicrobial resistance (AMR) occurs when microorganisms survive and even multiply in the presence of an antimicrobial agent that should normally kill or inhibit them. AMR spans bacteria, fungi, parasites, and viruses, making infections harder to treat, leading to persistent infections and increased mortality rates.

According to the World Health Organization (WHO), AMR is one of humanity’s top 10 global public health threats. It enables the emergence and spread of drug-resistant microorganisms, undermining medical advances and posing a significant challenge to global health.

AMR: A Cross-Cutting Concern

Antimicrobial resistance affects humans, animals, and plants, impacting all socio-economic classes and races. It also has significant economic implications, as infections that once required a single medication now need multiple and often more expensive treatments.

The primary driver of AMR is the misuse and overuse of antimicrobials across various sectors, including healthcare, agriculture, and animal husbandry.

Causes of Antimicrobial Resistance

1. Overuse and Misuse of Antimicrobials
   Frequent and unnecessary use of antibiotics in humans, animals, and agriculture promotes resistance. Antimicrobials without a doctor’s prescription can cause microorganisms to evolve and develop resistance. Additionally, misuse may kill the body’s beneficial bacteria, further exacerbating health problems.
2. Incomplete Treatment Courses
   Failing to complete prescribed medication allows some microorganisms to survive and develop resistance.
3. Poor Infection Control Practices
   Inadequate sanitation and hygiene in healthcare settings facilitate the spread of resistant microorganisms. The unregulated use of antimicrobials in such environments often worsens the problem.
4. Misuse in Agriculture
   Using antibiotics as growth promoters in livestock or routinely adding them to animal feed contributes significantly to AMR.
5. Inadequate Diagnostics
   Diagnosing infections with incomplete information often leads healthcare providers to prescribe broad-spectrum antimicrobials, increasing the risk of resistance.
6. Lack of New Antibiotics
   Insufficient investment in research for new drugs leaves healthcare systems unequipped to combat resistant strains.

Effect of Antimicrobial Resistance 

• Treatment Failures
  Routine infections and minor injuries may become life-threatening due to ineffective treatments.
• Increased Healthcare Costs
  Prolonged illnesses require extended hospital stays, more intensive care, and expensive treatments.
• Public Health Threats
  AMR undermines advancements in modern medicine, making surgeries, cancer therapies, and other medical procedures riskier.

Controlling Antimicrobial Resistance

1. Prudent Use of Antimicrobials
   Antibiotics should be taken only when prescribed by a healthcare professional, with strict adherence to dosage and regimen.
2. Improved Infection Control
   Promoting hand hygiene, vaccinations, and sanitation reduces the need for antimicrobials.
3. Strengthened Monitoring and Research
   Investing in surveillance systems for resistant infections, alongside the development of new antibiotics, diagnostics, and alternative treatments, is crucial.
4. Public Awareness Campaigns
   Educating the public on the dangers of antimicrobial misuse and overuse can help curb AMR.
5. Antimicrobial Susceptibility Testing
   This critical step ensures that healthcare professionals prescribe the right antimicrobials to combat specific infections effectively.
6. Multi-Drug Therapy
   When resistance occurs, healthcare professionals may use a combination of antimicrobials to treat infections effectively.

A Call to Action

Self-medication and incomplete medication courses must be avoided. AMR poses a severe threat to global health, food security, the economy, and development. Addressing AMR requires unified efforts from individuals, governments, healthcare providers, and industries.

By taking proactive steps and working together, we can mitigate the devastating effects of antimicrobial resistance and protect the health of future generations.
