How to prevent antibiotic resistance :pill:
Case study: MRSA
MRSA is resistant to antibiotics as a result of natural selection.
Methicillin-resistant Staphyloccus aureus
As doctors and nurses move from patient to patient, these antibiotic resistant bacteria spread easily.
In the 21st century MRSA contributed to over 1000 deaths in UK hospitals and care homes.
The Facts
Some bacteria develop resistance to antibiotics through mutations (change in their genetic material) that happen by chance. They produce new strains of bacteria by natural selection.
Antibiotics are used to kill bacteria that make us feel ill.
Bacteria can evolve rapidly because they reproduce at a fast rate.
Mutations in bacterial pathogens produce new strains.
Don't overuse antibiotics :female-doctor::skin-tone-4:
This is why doctors no longer use antibiotics to treat mild throat or ear infections, or illnesses that are believed to be caused by viruses.
Patients should finsh their course of medecine :spiral_calendar_pad:
This is to make sure all the antibiotics are killed by the antibiotic so none survive to mutate and form resistant strains.
Restrict the agricultural use of antibiotics :male-farmer::skin-tone-2:
This prevents the spread of antibiotic resistance from animal to human pathogens.
Use antibiotics when they are really needed :raising_hand:
Specific bacteria should be treated with specific antibiotics :coffin:
Hospitals should have high standards of hygiene :hospital:
Patients infected with antibiotic resistant bacteria should be looked after in isolation from other patients :mask:
Visitors to hospitals and care homes should wash their hands as they enter and leave :hand::skin-tone-5:
