Antimicrobial resistance (AMR) occurs when germs like bacteria, virus or fungus that cause infections resists the effects of the medication which is used to treat them. These resistant bacteria can spread and may infect people or animals because they form a protective covering which is harder to treat than non- resistant ones. This may eventually lead to treatment failure or they are unable to treat the source of infection.
Microbes develop Antimicrobial resistance through four mechanisms.
- Drug inactivation or modification
- Target site modification
- Decreased drug uptake
- Active drug efflux
AMR is generally a broader term. Since 1940s, antibiotics have saved millions of lives and has had helped in various lifesaving procedures like,
- Organ transplant
- Chemotherapy
- C- section
- Various surgeries
Why does AMR happen?
AMR is a natural process that happens over time through genetic changes in pathogens. It is mainly accelerated by human activity which is mainly due to taking these drugs without prescription or misuse and overuse of Antimicrobial to treat infection.
It is affecting all countries in all regions and at all income levels.
WHO identifies India and Vietnam as the most affected countries by the AMR. India is often called the ‘AMR capital of the world’.
People in these countries often take antibacterial medicines on their own and they use it with every infection whether it is antiviral infections, antifungal infections.
because of that people are developing resistance to it. Now the resistant bacteria survive the present medicines which leads to slow cure of the disease, mortality, persistence of disease and costly alternative antibiotics. People who have weakened immune systems, long term antibiotic users, children, older people.
To prevent it, overprescribing of antibiotics should be stopped, it should not be taken when there are antiviral or antifungal infections, it should be taken only when healthcare professionals prescribe them, and practice good hygiene.
