Antibiotic resistance: A global danger
What is antimicrobial resistance (AMR)?Antimicrobial resistance is when a microorganism (like a bacteria or a virus) can stop an antimicrobial (such as antibiotics, antivirals, and antimalarials) from working against it. Since the 1950s many new antibiotics have been developed, but when these are overused the bugs that they target quickly become resistant rendering the drugs useless.The first superbug resistant to multiple antibiotics, methicillin-resistant staphylococcus aureus (MRSA), was identified in the U.K. in 1962.
We have now seen resistance to almost every antibiotic we have in use today.
The size and scale of the problem
- Harmful bacteria are living organisms and will fight for survival like every other species.
- Antimicrobials leach from animal waste, waste water, and sewage into the natural environment.
How does AMR spread?
- The high use and sometimes misuse of antimicrobial agents.
- Infection of patients with hospital acquired resistant bacteria (e.g., MRSA, Enterobacteriaceiae), which may then be carried back to communities.
- Hospital waste water which releases a high load of antimicrobials and AMR organisms into the environment.
- They can be used indiscriminately, for a partial course of treatment before being discarded.
- They can be given for viral or minor infections where they are not needed.
How can we tackle the problem of AMR?
- Good Infection control and hospital hygiene practice. This includes good levels of staffing, hand hygiene policies, operating theatre procedures, post-operative care, and isolation facilities.
- Generating good community level data. This includes knowing which types of bacteria are in circulation in the community at a given time, and which antibiotics they are susceptible to.
- Education and training of antimicrobial “gate keepers”. This includes training for all antimicrobial prescribers and dispensers, including hospital staff, students, and drug vendors as well as reviewing and updating antimicrobial prescribing guidelines. It also includes having better tools for the recognition of serious and life threatening infections.
AMR and the SDGs
- Globally, at least 700,000 people die each year of drug resistance in illnesses such as bacterial infections, malaria, HIV/AIDS, or tuberculosis and this problem is only set to increase.
- It is estimated that AMR could reduce the global economy by $100 trillion by 2050.
“Strengthen the capacity of all countries, in particular developing countries, for early warning, risk reduction and management of national and global health risks.”
Thinking about the other SDGs, we can see how AMR is intertwined with many other global problems.“[W]e will equally accelerate the pace of progress made in fighting malaria, HIV/AIDS, tuberculosis, hepatitis, Ebola and other communicable diseases and epidemics, including by addressing growing antimicrobial resistance and the problem of unattended diseases affecting developing countries.”
- SDG 2 which aims to end hunger, will be affected by the use of antibiotics in agriculture.
- SDG 8 which aims to secure productive employment for all.
- SDG 12 which aims to achieve sustainable production and consumption of resources, such as antibiotics.
