Answer:
Antibiotic Resistance
Step-by-step explanation:
Antibiotic Resistance is when bacteria mutates or adapts to become resistant to antibiotics, wether by protecting the bacteria itself or limiting how the antibiotics can effect the body. This antibiotic Resistance can happen from using too many antibiotics, or using antibiotics but not having a high enough dose (so all the bacteria isn't killed). This can cause much more serious infections, like pneumonia and meningitis, to happen, and they can last longer, as they may not immediately respond to treatment. These can also spread to people who don't have a problem with antibiotic Resistance, but will get the antibiotic resistance bacteria which can mess with the other bacteria in their body, making them antibiotic resistant, which turns into a cycle of spreading bacteria and becoming resistant.
