Is open defecation source of Zim’s health crisis?
Lazarus Sauti
Zimbabwe is scrambling to contain an outbreak of typhoid, with 2 160 cases
reported which had led to seven deaths earlier this week.
The Ministry of Health and
Child Care says typhoid is a major concern in various parts of the country.
“The cumulative figures for
typhoid are 2 159 suspected cases, 77 confirmed cases and seven deaths,” the
ministry said in its weekly briefing.
There were 10 suspected
cases of cholera with three of them confirmed and one death reported.
Health and environmental
experts believe open defecation – the practice whereby people go out in fields, bushes,
forests, open bodies of water, or other open spaces rather than using the
toilet to defecate – is greatly to blame for waterborne diseases such as typhoid
and cholera currently affecting Zimbabweans.
Nationally,
37 percent of rural households still practice open defecation, according to
statistics from an annual Zimbabwe Vulnerability Assessment Committee (Zimvac)
report for 2016.
“Zimbabwe
is battling with waterborne diseases like typhoid and cholera, thanks to open
defecation, poor water quality, uncollected waste in urban and semi-urban areas
as well as unhygienic practices,” says water and sanitation expert, Matthew
Chiramba. “Open defecation is the source of organic, bacterial, ground water
and surface water pollution. It also pollutes catchment areas.”
He
adds that open defecation also impacts on personal dignity, especially on women
and girls as they risk shame, disease, harassment and attacks.
Environmentalist,
Edson Nyahwa, says open defecation is a serious environmental as well as health
and safety issue confronting Zimbabweans as improperly disposed human waste not
only pollutes water, killing plants and fish, but also releases methane gas
into the atmosphere which is part of the green house gasses that cause global
warming.
“Open
defecation should be equated to an environmental as well as health crime. It
impacts negatively on socio-economic development and should not be tolerated if
the country is to attain the Sustainable Development Goal (SDG) on sanitation,”
he adds.

City Council Health Services director, Dr. Prosper Chonzi, believes
stakeholders should put a lot of effort towards addressing environmental issues
that drive waterborne diseases such as typhoid and cholera.
Nyahwa
also says that the management of wastes must be considered, and conventional
sewerage should be supplemented with ecological sanitation technologies that
make use of nutrients in human waste.
“The
government, at every level, and stakeholders in environment, water and
sanitation sectors should invest more in the provision of water and public
toilets, create awareness on the dangers of open defecation as well as encourage
the anaerobic digestion of sewage to produce biogas for energy,” he adds.
Traditional
leader, Robson Wagoneka, says open defecation, which he also considers as a
well-established traditional practice deeply ingrained from early childhood, reduces
the aesthetic beauty of an area, and believes social norms and habits need
to be changed if the practice is to be eliminated.
“Building
public toilets is a good move and vital for improving the lives of people,
especially the poorest, but honestly it will not do the job,” Wagoneka says. “Changing
social norms and habits will achieve the desired goals.”
He
also urges the government to support as well as strengthen the participation of
local communities in improving water and sanitation management.
Wagoneka
adds that there is a serious need for health education and promotion on
personal hygiene, a fact supported by Dr Portia Manangazira, the Director in
the Ministry of Health and Child Care responsible for Epidemiology and Disease
Control, who adds, “There is also need to avail resources for the training of
more health personnel so that they gain understanding of diagnosing diseases
such as typhoid as well as cholera and quickly put patients on medication.”
In-depth
research, notes the Zimvac (2016) report, is required to understand the casual
factors of the relatively high prevalence of open defecation across the
country.
