A new strain of bacteria that can cause serious infections in children but evades standard treatments is spreading in Europe.
MRSA (meticillin-resistant Staphylococcus aureus) is a type of bacteria that has evolved to the point where first-choice antibiotics no longer work against it, making it harder to treat. It can cause serious health problems if it gets inside the body, causing more than 100,000 deaths worldwide in 2019.
