Antibiotic Resistance: Your Guide to Understanding Superbugs

When it comes to fighting infections, antibiotics have long been the gold standard. But some infections have bacteria with superhero-like powers. These bacteria are called superbugs, and they're a growing health concern. Read on to learn more about how antibiotic-resistant superbugs happen and what you can do to stay healthy.

What is an antibiotic?

Antibiotics are a type of medicine that kills or stops the growth of harmful bacteria that cause infection, such as bladder or kidney infections. Some examples of antibiotics are penicillin, amoxicillin or azithromycin (Z-Pak).

What is antibiotic resistance?

Antibiotic resistance means that the antibiotic is unable to kill the bacteria and stop it from growing. This happens when bacteria become stronger than the drugs meant to kill them. Antibiotic resistance makes infections harder to treat.

Why does antibiotic resistance happen?

When antibiotics are used, they kill some bacteria, but others may survive and multiply. Over time, the surviving, resistant, bacteria become more common.

Why is antibiotic resistance a concern?

Antibiotic resistance can lead to infections that are difficult, and sometimes impossible, to treat. Each year, 2.8 million Americans get a serious infection caused by antibiotic-resistant bacteria. The World Health Organization has named antibiotic resistance a top global public health threat.

What are antibiotic-resistant superbugs?

Superbugs are bacteria that are resistant to most, if not all, antibiotics. These differ from common viruses, which are smaller, invasive germs that usually cause full-body symptoms.

How are superbugs related to antibiotic resistance?

Superbugs are caused by antibiotic resistance. When bacteria grow strong enough to withstand the effects of antibiotics, they become superbugs - or antibiotic-resistant infections.

What are common superbugs?

Three common superbugs are methicillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile (C. diff) and vancomycin-resistant Enterococci (VRE).

What causes antibiotic resistance to develop?

Antibiotic resistance can happen for many reasons. Two common reason reasons are using antibiotics too often, or not using them correctly. This can happen if you take antibiotics when you don't need them, or if you don't finish the full course of treatment.

How can antibiotic resistance be prevented?

To prevent antibiotic resistance, you should only take antibiotics when needed and as prescribed by your doctor. Using good hygiene, such as handwashing, can also help stop the spread of resistant bacteria.

Are there ways to treat antibiotic-resistant superbugs?

Yes, there are ways to combat superbugs. New treatments like phage therapy - using viruses to kill bacteria - and immunotherapy may help fight off superbugs. New antibiotics to treat superbugs are also being researched.

Do I need antibiotics?

Some sicknesses can easily be treated with antibiotics, while others illnesses have to run their course. Use the chart below to help find out what might be causing your symptoms.
