While medical research has helped us overcome many health threats, we now face a new type of crisis: Many dangerous bacteria are becoming resistant to the drugs meant to fight them. Where do we go from here?
Healthcare professionals frequently
use antibiotics to treat many
forms of bacterial infection — from those that are mild to those that are
potentially life threatening.
These bacteria-fighting drugs first
became widely used in the early 20th century, though some medical historians
argue that natural antibiotics featured in traditional therapies as early
as 350–550Trusted
Source.
For the most part, antibiotics have
proved to be a crucial ally in the fight for health, but over the past few
years, these drugs have begun to lose their footing in their confrontation with
bacteria.
This is because more and more
bacterial strains are developing antibiotic resistance — they are no longer
affected by the drugs that once suppressed their growth and activity.
This means that many bacteria have
become more threatening because we have fewer means of offsetting them.
When a doctor finds that a bacterial
infection is not responding to traditional antibiotic treatment, they are
forced to use stronger, more aggressive antibiotics or antibiotic combinations
— an increasingly restrictive approach that can also bring about unwanted
effects on health.
So how did we get here, and are
things quite as bad as they seem? More importantly, what can doctors, researchers,
and the public do to address the ever-growing issue of antibiotic resistance?
A growing health crisis
Only last week, the Centers for
Disease Control and Prevention (CDC) released a reportTrusted Source reviewing the newest
data on antibiotic resistance.
From the very first page, they make
it clear that we are facing an important threat — the CDC dedicate this report
to "the 48,700 families who lose a loved one each year to antibiotic
resistance or Clostridioides difficile, and the countless healthcare providers, public health
experts, innovators, and others who are fighting back with everything they
have."
The
situation is dire indeed: According to the newest data, more than 2.8 million
people in the United States experience an infection from antibiotic resistant
bacteria each year. Moreover, these "superbugs" cause 35,000 deaths
per year in the country.
This threat is by no means new. It
has persisted over the years, as Dr. Jesse Jacob — a specialist in bacteria
resistant to multiple drugs, from the Emory Antibiotic Resistance Center at the
Emory University School of Medicine, in Atlanta, GA — has told Medical
News Today.
"[The] CDC released the first
antibiotic resistance threat report in 2013, so this [situation] is not
new," Dr. Jacob told us.
Although, he added, "Since the first report, the number of deaths due to these infections has declined [...] CDC has updated the estimated number of infections with antibiotic resistance per year from 2 million to nearly 3 million."
Although, he added, "Since the first report, the number of deaths due to these infections has declined [...] CDC has updated the estimated number of infections with antibiotic resistance per year from 2 million to nearly 3 million."
The fact that so many bacteria are
not responding to first- or even second-line treatments means that people with
these infections face much higher risks and poorer health outcomes.
"Antibiotic
resistance has long been a problem, but the threats we face are real,
immediate, and demand immediate action. Antibiotic resistance threatens modern
medicine — our ability to safely perform routine surgeries and complicated
organ transplants, as well as chemotherapy, all rely on
the ability to prevent and treat infections."

Consistent antibiotic overuse
"Antibiotic resistance is not
only a U.S. problem — it is a global crisis," the recent CDC report
states. But what has led to this problem reaching a crisis point?
The answer to that question is
complex, according to a review featured in the journal Pharmacy and TherapeuticsTrusted Source. The first and perhaps most
obvious cause of antibiotic resistance is the misuse and overuse of these drugs.
Some people mistakenly believe that
taking any kind of antibiotics acts as a sort of panacea, and they use these
drugs to treat illnesses such as influenza. However, antibiotics
can only target and kill bacteria and thus only treat bacterial infections.
Antibiotics are powerless against
influenza and other illnesses caused by viruses. So when someone takes
antibiotics for the wrong illness or uses too many too often, this kills off helpful bacteriaTrusted Source that populate the body, threatening the
delicate balance upon which health depends.
Moreover, bacteria are naturally
prone to evolve and mutate, and some bacterial strains have, over time, found
ways to adapt so that certain antibiotics will not affect them.
When we take antibiotics at the wrong time or if we overuse them, this allows resistant bacteria to take over more easily — to spread and multiply, sometimes giving rise to further strains of antibiotic resistant bacteria.

In the
U.S. and other countries around the world, pharmacies are not permitted to sell
antibiotics to people who are unable to produce a prescription.
Nevertheless, studiesTrusted
Source suggest that many people are still able to purchase
these drugs without official recommendations from their doctors.
Additionally, some research has
shown that doctors sometimes mistakenly prescribe antibiotics or prescribe the
wrong type of antibiotic, which has likely contributed to the current health
crisis.
According to one study paper, 30–60% of antibiotics that doctors prescribe
to people in intensive care units are not necessary.
