The Role of Inadequate Water, Sanitation, and Hygiene (WASH)
Infrastructure in Sustaining Cholera Outbreaks in Sub-Saharan Africa
WASH Deficits and Cholera Persistence in Sub-Saharan Africa 2
Introduction
Insufficient clean water, poor sanitation and poor hygiene (WASH) systems in the region
make cholera a serious health challenge in Sub-Saharan Africa. According to Asantewaa et al.
(2024), despite global actions to control cholera, LMICs, particularly in Sub-Saharan Africa, are
still affected by frequent outbreaks and many deaths. Experts estimate that every year, the
number of cholera cases globally ranges from 1.3 million to 4.0 million and the number of
people who die from the disease ranges from 92,000 to 143,000 (Asantewaa et al., 2024).
Because cholera cases and deaths are linked to large numbers in the community, upgrading water
and sanitation services works best. In their article titled “Cholera outbreaks in low- and middle-
income countries in the last decade: a systematic review and meta-analysis,” Asantewaa et al.
(2024) look closely at the various ways and reasons cholera outbreaks take place in LMICs.
Through this review, I will examine the research done by Asantewaa et al. (2024)
regarding how a lack of proper infrastructure for water, sanitation and hygiene supports the
growth of cholera outbreaks in Sub-Saharan Africa. The reason is to learn about changes in the
disease, its treatment and areas where the system is lacking by reading up-to-date studies.
Article Summary and Infectious Disease Epidemiological Background
Asantewaa et al. (2024) conducted a systematic review and meta-analysis of cholera
outbreaks in LMICs between 2010 and 2022, focusing on epidemiological characteristics, risk
factors, and response mechanisms. Lack of water supply, greater numbers of people living in the
city and the way cholera was handled, were considered the main reasons the epidemic didn’t end.
A number of recent events have shown that we should spend more energy on disaster planning,
check on public health and improve waste, sanitation and hygiene systems. Using proper water,

soaping and toilet facilities is the most recommended way to avoid getting cholera, says the
study.
The major topics focus on teamwork, early observation to see signs of danger and ways
to be active members of their communities. Making improvements to water and sanitation and
investing more in clean water systems should be covered in cholera plans. It proves that not
investing a lot in sanitation, water and hygiene facilities has allowed cholera to spread in Sub-
Saharan Africa.
Epidemiology of the Infectious Disease and Disease Impact on Populations
Anyone who swallows Vibrio cholerae bacteria contaminated foods may develop cholera
with rapid diarrhea. Above all, when treatment fails, the body can experience high water loss and
death is possible. Epidemiologically, Sub-Saharan Africa bears a disproportionate burden of
cholera, with countries like Nigeria, the Democratic Republic of Congo, and Mozambique
frequently experiencing large-scale outbreaks (Ahmed et al., 2024).
Climate change, people being displaced and poor city housing seem to be increasing
disaster risks. According to Kyeng et al. (2024), cholera surveillance systems in Africa are often
fragmented and under-resourced, making it difficult to predict or contain outbreaks. The disease's
impact is most severe in slums and refugee camps, where sanitation is minimal and access to
clean water is scarce. In case cholera breaks out, businesses may close, students stay at home and
the healthcare system becomes very busy.
Best Practices or Standard of Care
Processes for water, sanitation and hygiene are required in Sub-Saharan Africa to face
cases of cholera. Part of best practices is providing drinking water that is safe, constructing toilet

facilities and recommending clean hygiene habits (Sikder et al., 2023). Bringing WASH into
school health programs and applying CLTS seem to be successful in helping solve the issue.
Communities at risk of cholera greatly benefit from the use of oral cholera vaccines (OCVs).
According to Asantewaa et al. (2024), both emergency steps and ongoing sustainable efforts are
important in response to outbreaks.
According to Okesanya et al. (2024), community-appropriate WASH programs helped to
boost adoption since they reflect the peoples beliefs and habits. When WASH programs are
gender-sensitive, all people can use the facilities safely and women and girls improve their
chances of good health.
Evaluation and Critique
Comparison and Contrast
Asantewaa et al. (2024) emphasized the centrality of inadequate WASH in the recurrence
of cholera, a position echoed across the literature. For example, Ahmed et al. (2024) similarly
highlighted how neglect and underreporting of cholera outbreaks in Sub-Saharan Africa have
masked the urgency of investing in WASH systems. Both a poor infrastructure and weak
leadership, as the studies show, stop progress in tackling recurring epidemics.
Kyeng et al. (2024) complement Asantewaa’s findings by critiquing the limited
effectiveness of existing surveillance systems. Kyeng and his team pay special attention to how
surveillance can inhibit outbreaks which is generally overlooked. It points out that, if monitoring
is lacking, WASH actions might happen when the outbreak has already started.
Sikder et al. (2023) offer a more focused investigation into the environmental aspects of
cholera, revealing the direct correlation between poor sanitation, contaminated water sources,
WASH Deficits and Cholera Persistence in Sub-Saharan Africa 5
and disease prevalence. Research supports that Asantewaa was correct: Water, sanitation and
hygiene help guard against cholera.
In contrast, Okesanya et al. (2024) provide a broader view of WASH, linking it to
sustainable development goals (SDGs) and gender equity. They connect WASH to cholera and
then they discuss ways that social-political issues influence the situation and stress the need to
back nearby communities.
They all agree WASH infrastructure has to improve, but they each assign varying
importance to observance, cleanliness, dealing with local people and the outcomes lasting.
Evaluative Critique
Asantewaa et al. (2024) present a comprehensive review supported by strong statistical
analysis and broad geographical coverage. One of the study’s main strengths is its inclusion of
multiple LMICs, allowing for a diverse understanding of cholera trends. However, its limitation
lies in the generalized policy recommendations, which may not be easily translatable to specific
country contexts. The article could benefit from more detailed case studies and actionable steps
for policymakers.
Additionally, while the meta-analysis is methodologically sound, the review depends
heavily on reported data, which, as Ahmed et al. (2024) pointed out, is often incomplete or
inaccurate in Sub-Saharan Africa. Yet, the work done by Asantewaa and her team makes clear we
should bring WASH and policy changes together.
Conclusion
WASH Deficits and Cholera Persistence in Sub-Saharan Africa 6
Since water, sanitation and hygiene systems are not strong in the region, Sub-Saharan
Africa is where most cholera cases occur. Asantewaa et al. (2024) provide a strong foundation
for understanding the interconnectedness of sanitation, water access, and disease transmission.
For these reasons, many experts think we should use broad WASH approaches, better
surveillance and selections that are right for each place to avoid frequent cholera outbreaks.
Ensuring that community cooperation, strong rules and properly constructed infrastructure are a
priority is important in public health.
