If a pathogen changes by mutation the new strain may spread rapidly.

How can we prevent antibiotic resistance developing?
Antibiotic should only be used if they are really needed. Specific bacteria should be treated with specific antibiotics. Medical staff should wear disposable clothing and visitors/staff should wash their hands. Patients kept isolated if infected.

Why is mutation in bacteria and viruses such a problem?
If bacteria or viruses mutate, new strains of the pathogen can appear causing disease. New strains of disease which spread rapidly can cause epidemics/pandemics. Antibiotics/vaccinations may not be effective against a new strain.
