The UNDERSTAND focus area of the toolbox provides information and tools for increased knowledge about bacteria, antibiotics and antibiotic resistance, and aims to explain why antibiotic resistance has become one of the major health challenges of our time. The focus area further discusses why it is important to take action against this negative development and gives an introduction to possible ways to do so.

Antibiotics – cornerstones of medicine
The discovery and introduction of antibiotics to treat bacterial infections is one of the single most important advancements in human medicine. From treatment of pneumonia and gonorrhea to prevention and treatment of infections that can arise after major surgery or chemotherapy, antibiotics have become indispensable. Overall, antibiotics have greatly improved human health and animal welfare. They really are the cornerstones of modern medicine.
Unfortunately, the growing phenomenon of antibiotic resistance now threatens to leave us without effective treatment of bacterial infections. Over time, some bacteria have found means to avoid and survive the action of antibiotics. As resistance increases, antibiotics that were once effective stop working. Use and misuse of antibiotics in health care, food production and by people in the community has lead to the selection and proliferation of antibiotic resistant bacteria. These resistant bacteria then spread to other people, animals and in the environment, facilitated by poor hygiene and sanitation practices, human travel and trade. At the same time, very few new antibiotics are under development.
Antibiotic resistance – the silent tsunami
Resistance has already reached a critical point for some major infections and the consequences can be seen worldwide. Data on the actual health and economic burden of antibiotic resistance is scarce. Some of the more reliable estimates on the number of deaths caused by antibiotic resistant bacteria each year and the costs for society are discouraging:
|Country and number of deaths||Societal costs|
|Thailand: More than 19,000||~85-200 million USD direct, more than1.3 billion indirect|
|USA: 36,000||Up to 20 billion USD direct, up to 35 billion indirect (figure from 2013 report)|
|European Union: 33,000||~1.5 billion Euros|
And this is only the tip of the iceberg as only a few selected bacteria were included in these estimates. Antibiotic resistance has an especially devastating impact on people living in low- and middle-income countries, where for example treatment failure in pneumonia or blood stream infections among children results in large number of deaths. Studies from South Asia (India, Pakistan, Afghanistan, Nepal, Bangladesh) indicate that blood stream infections with resistant bacteria alone kill 98,000 newborns each year. This means that one child looses its life every five minutes because the available antibiotics are useless due to resistance! Many more have suffered from resistant infections but recovered.
The World Health Organization (WHO) has stated that bacterial resistance to antibiotics is a major global threat to public health, and warned that we are heading toward a post-antibiotic era where common bacterial infections that have been treatable will once again be associated with high mortality rates.
A complex issue
The issue of antibiotic resistance is complex, and so are possible solutions to manage the situation. To halt the spread of resistance and reach sustainable solutions, multiple interventions are needed on many levels in society all around the globe. The only true way forward must involve global collective action applying a holistic perspective. This means that both the human and animal sector as well as environmental and financial consequences must be taken into consideration. All efforts are important, from decisions and actions by individuals to large-scale initiatives by governments.

|Antibiotic Resistance: An Ecological Perspective on an Old Problem||Report that highlights the need of co-existence with resistance instead of fighting it. To be able to do this and save life, strategies can be developed to prevent new resistance from spreading, identify strains we need to protect against, manage reservoirs of antibiotic resistant strains in the environment and find effective treatment in patients infected with resistant bacteria.
