The Pandemic Within the Pandemic
Apr 26, 2021LOICE ACHIENG OMBAJO
Globally, antibiotic use in hospitals has surged since the start of the
COVID-19 pandemic, and over-the-counter sales, legal in many countries, have
soared. This is further fueling the global crisis of antimicrobial resistance,
as bacteria evolve and become immune to these drugs.
NAIROBI – Fear of COVID-19 is driving
increased over-the-counter (OTC) sales and in-hospital prescriptions of
antibiotics – and fueling a silent pandemic in its wake.

that the waiver of COVID-19-related patents, including for vaccines, has become
a moral imperative.

Globally, antibiotic use in
hospitals has surged since
the start of the COVID-19 pandemic. Even though studies show that only 8% of patients
admitted to hospital with COVID-19 also have an infection requiring
antibiotics, more than 70% receive them. In addition, many people worried about
possible or actual COVID-19 symptoms, and alarmed by global reports about the
pandemic, have turned to buying antibiotics without seeing a health-care
worker.
This is further fueling the global
crisis of antibiotic resistance, as bacteria evolve and become immune to these
drugs. We must move quickly – with international policy, national laws, and
local action – to control what the World Health Organization has identified as one
of the ten leading health threats to humanity.
Antibiotics treat infections caused by
bacteria, and have no impact on a virus such as SARS-CoV-2, which causes
COVID-19. Overusing them merely accelerates the emergence of antibiotic
resistance, which will undercut our ability to treat common diseases. Simple
infections such as pneumonia or urinary tract infections, which currently can
be quickly cleared by common antibiotics, may prove impossible to treat and
become deadly.
This is particularly true in many
African, South American, and Asian countries, where access to health-care
workers is limited and there are no restrictions on antibiotic sales. In India,
antibiotic sales have risen astronomically in recent years, largely driven by
unregulated OTC purchases, including of unapproved drugs.
Likewise, in Kenya, all antibiotics can be purchased without a prescription.
Bacteria that develop resistance to
multiple antibiotics are responsible for causing difficult-to-treat infections,
which are up to three times more likely to kill people than
infections caused by non-resistant bacteria. And data from several countries –
including China and Egypt – indicate
that up to 50% of bacteria-causing infections in critical-care units are
resistant to several antibiotics. In the United States, it is
estimated that close to three million people get an antibiotic-resistant
infection each year, leading to more than 35,000 deaths annually.
Drug-resistant bacteria are also more
likely to spread from person to person, and have been known to cause large
disease outbreaks in
hospitals. Many COVID-19 treatment wards around the world are currently
grappling with this problem.
As an infectious-disease specialist working
on the COVID-19 management front line and also leading the treatment of
drug-resistant infections in Kenya, I have often struggled to treat patients
with severe bacterial infections that had developed resistance to all available
antibiotics. Many of the recently developed drugs that could potentially treat
resistant bacteria are often extremely expensive and not available in many
countries. A ten-day course of one such antibiotic in Kenya, for example, costs
almost $10,000, putting it beyond the reach of most patients.
In fact, many patients entering the
hospital for COVID-19 treatment say that they have already taken one or more
antibiotics at home in an attempt to address some of their symptoms. Often,
using these drugs had made them feel that they were being treated, so they
delayed going to the hospital.
Some may argue that allowing
unrestricted use of antibiotics can enable access to treatment for those
unlikely to be able to see a doctor, and may be cheaper for the poor. But the
resulting antibiotic resistance is expensive to treat and potentially costs
lives.
What must we do to forestall this next
pandemic? For starters, the WHO and other global agencies must speak out much
more strongly and explicitly against the use of antibiotics in cases of COVID-19,
unless these drugs are specifically indicated for another bacterial infection.
In addition, national governments must
tighten restrictions on OTC antibiotic purchases. Evidence suggests that
introducing and enforcing laws to limit such sales can be effective if these
efforts are sustained over time. Requiring pharmacies to display a notice stating that it is
illegal to sell antibiotics to customers without a doctor’s prescription also
has been associated with reduced antibiotic sales.
Hospitals should adopt so-called antibiotic stewardship strategies
to reduce unnecessary prescriptions. These measures can lead to reduced antibiotic use and cost,
and decrease the risk of antibiotic-resistant infections in hospitals.
Effective strategies could include developing guidelines for managing common
infections, restricting antibiotic use in viral infections, strengthening
laboratory capacity – especially in low- and middle-income countries – to help
clinicians identify the correct bacteria to treat, and providing continuing
education for all clinicians.
Finally, individuals – despite their
understandable fears of COVID-19 – should not risk harming themselves by using
antibiotics unnecessarily.
The message is clear: if we do not act
now to curb antibiotic use, we will invite a new pandemic. And, unlike
COVID-19, no vaccine will save us.
