What are superbugs?

Superbugs are microbes that become resistant to medicine. This makes infections caused by superbugs very difficult to treat. Superbugs can spread quickly and pose a serious health threat to all of us. The latest research shows that superbugs were linked to an estimated 5 million deaths worldwide in 2019. This is predicted to rise to 10 million deaths a year by 2050 – or 1 death every 3 seconds

Why are superbugs on the rise?

Antibiotics are being routinely overused and misused in humans, animals, and plants, according to the World Health Organization (WHO)

Other reasons for the worldwide spread of superbugs include:

  • poor access to clean water, sanitation, and hygiene facilities (WASH)
  • poor infection prevention and control
  • poor access to quality medicines, vaccines, and diagnostics
  • poor access to antimicrobial stewardship education and training
  • poor awareness and knowledge

Additionally, new antibiotics are not being developed fast enough to keep up with increasing rates of resistance

Glossary of terms

Acquired Resistance

When bacteria develop the ability to resist antibiotics through mutation or gene uptake

Antibiotic

A type of medicine used to treat bacterial infections

Antibiotic Stewardship

Efforts to use antibiotics responsibly to avoid resistance

Antimicrobial

Any substance that kills or inhibits the growth of microorganisms

Antimicrobial Resistance (AMR)

When microorganisms, like bacteria, no longer respond to medicines meant to kill them

Background Resistance

The natural, low-level resistance to antibiotics found in a population of bacteria

Using viruses that infect and destroy bacteria as a treatment

Broad-spectrum Antibiotics

Antibiotics that are effective against a wide range of bacterial species

Carbapenem-resistant Enterobacteriaceae (CRE)

A group of bacteria that have become resistant to carbapenem antibiotics, which are often used as a last resort

Extended-spectrum Beta-lactamases (ESBLs)

Enzymes produced by some bacteria that break down and resist beta-lactam antibiotics
