Science Drives Everything with 25,000 clinical researchers testing every day and cutting-edge innovations, our science holds the cure
Infectious diseases continue to be one of the biggest public health concerns around the world. Since our pioneering work on penicillin in the 1940s, we have a strong history of addressing this evolving risk1.
Infectious diseases are caused by pathogens invading the body, and they fall into four major types, namely bacterial infections, fungal infections, viral infections, and parasitic infections1.
Anti-infectives are medicines that work to help treat infections1. They include antibacterials, antivirals, antifungals, and antiparasitic medications1. Anti-infectives have revolutionized healthcare, and thanks to anti-infective therapies, we now can:
Treat minor infections and many serious infectious diseases, like pneumonia or tuberculosis1.
Perform routine procedures and complex surgery, such as cesarean sections or joint replacements, which carry a risk of serious infection1.
Give vital immuno-suppressive treatments, like chemotherapy, to people with cancer1.
