WHO Collaborating Centre Antimicrobial Resistance Epidemiology and Surveillance
Antimicrobial resistance (AMR) is a growing problem throughout the world. Insight into current national AMR problems is a prerequisite for an effective and targeted approach to AMR. However, not all European countries have a national surveillance network for AMR as yet. This was the reason for setting up the CAESAR project. CAESAR stands for Central Asian and Eastern European Surveillance of Antimicrobial Resistance.
Colds, flu and most other infections are caused by viruses. Some infections – such as bladder infections or pneumonia – are caused by bacteria. These infections can be treated with antibiotics, which either kill the bacteria or suppress their growth. If the same antibiotic is regularly used against a bacterium, then that bacterium can become ‘resistant’. This means the bacterium will no longer be susceptible (vulnerable) to that particular antibiotic. If you become infected with these resistant bacteria, then that antibiotic will no longer be of any help. The resistant bacteria will not be suppressed, meaning you can become very ill. That is why infections like these are more difficult to treat.
