Healthy Friday: Superbugs’ resistance to antibiotics is growing globally

If a bacterium carries several resistance genes, it is called multiresistant or a superbug. New resistance mechanisms in bacteria are emerging and spreading globally, threatening our ability to treat common infectious diseases. Without urgent action, we are heading for a post-antibiotic era, in which common infections and minor injuries can once again kill.

Antibiotic resistance

Antibiotics are used to prevent and treat bacterial infections – not viral infections. Antibiotic resistance occurs when bacteria change in response to the use of antibiotics, becoming resistant to them. Bacteria, not humans or animals, become antibiotic-resistant.

Bacteria are fighting back

 

Overuse of antibiotics causes antibiotic resistance

Antibiotics are not effective against viral infections like the common cold, flu, most sore throats, bronchitis, and many sinus and ear infections. Widespread use of antibiotics for these illnesses is an example of how overuse of antibiotics can promote the spread of antibiotic resistance.

In countries without standard treatment guidelines, antibiotics are often over-prescribed by health workers and veterinarians and over-used by the public. There are countries where antibiotics can be bought for human or animal use without a prescription which makes the emergence and spread of antibiotic resistance worse.

 

What can be done about antibiotic resistance?

The world urgently needs to change the way it prescribes and uses antibiotics. Even if new medicines are developed, without behaviour change, antibiotic resistance will remain a major threat.

What can you do to control the spread of antibiotic resistance?

  • Only use antibiotics when prescribed by a certified health professional.
  • Never demand antibiotics if your health worker says you don’t need them.
  • Always finish your course of antibiotics.
  • Always follow your health worker’s advice when using antibiotics.
  • Never share or use leftover antibiotics.
  • Prevent infections by regularly washing hands, preparing food hygienically, avoiding close contact with sick people, practising safer sex, and keeping vaccinations up to date.
