About Anti-Infectives


What are anti-infectives?

Anti-infectives are medicines that work to prevent or treat infections, they include antibacterials, antivirals, antifungals and antiparasitic medications.

Why are anti-infectives so important?

Anti-infectives have revolutionized healthcare and are now critical in curing and even helping to prevent many kinds of infection. Thanks to anti-infectives, we can:1

  • Treat minor infections and most often cure many serious infectious diseases, like pneumonia or tuberculosis
  • Perform routine procedures and complex surgery, such as cesarean sections or joint replacements, which carry a risk of serious infection
  • Give vital immuno-suppressive treatments, like chemotherapy, to people with cancer

Alarmingly, many anti-infectives are losing their effectiveness due to antimicrobial resistance (AMR).1

What causes infection?

Infectious diseases continue to be one of the biggest global public health concerns.1 But what causes infections in the first place?
