Cholera is a communicable infection that predominantly transmitted by the bacterium Vibrio cholerae after ingesting contaminated water or food. It causes excessive diarrhoea and vomiting can result in severe dehydration. V. traces its natural habitat waterlogged settings, therefore, to effectively manage spread of cholera, it critical research interactions disease's causative agent with human comportment ecosystem [1]. Despite momentous breakthroughs have been documented medical field, cholera remains public health threat some countries Sub-Saharan Africa (SSA) as well East Mediterranean Region (EMR), claims thousands lives, whenever there an outbreak. The crises are persistent regions lack adequate supply experience poor sanitation hygiene services (WASH) alongside substandard healthcare infrastructure [2]. However, productively highlight neglected incidences reemerge year year, SSA, important carry out detailed investigations their systemic limitations propagate reoccurrence [3]. Thereafter, coming up sustainable solutions widely address this ongoing crisis (Table 1). social constraints such gender inequalities contribute challenge posed due scarcity. Girls women bear burden caregiving during outbreaks they usually forefront [4]. Healthcare expenditures tend strain fragile economies reduce productivity. cost treatment varies significantly depending on factors WASH infrastructure, severity outbreaks, access resources. In Somalia for instance, overall average facilities households was estimated be US$ 116.59 2023 [5]. This hefty considering socioeconomic inequality, disproportionately affects society. Additionally, young population below age five highly susceptible, especially those little no food eat, malnutrition renders disease vulnerability children, compromised immune systems. Their bodies find hard defend themselves against foreign invaders [6]. epidemics repeatedly erupt foreseeable periods Africa, frequently align rainy seasons intensified environmental infrastructural dynamics [7]. infectious remarkably prevalent where Zambia, Nigeria Democratic Republic Congo succumbed major episodes recorded high case fatality rates [8]. According World Health Organization (WHO), SSA reports highest number cases, globally, region records over 150,000 laboratory confirmed about 3,000 deaths annually [9].In several specifically conflict-affected rural areas, centres not fully equipped execute timely diagnosis reporting cases. As result, most remain masked both national international authorities, until escalate [10]. Political influences equally play key role, governments may shy away from fear ruining reputation suppressing tourism industry discouraging investment. prolonged regional internal conflicts prevalence chapters SSA. They disrupt systems cause limited quality [11].Furthermore, drainages, settings [12]. Climate change including floods droughts contaminate sources [13].Insufficient vaccination coverage, particularly hard-to-reach districts also chief [14]. density refugee camps together informal settlements urban areas increase transmission rate, turning small into large-scale [15]. Similarly, EMR, pressing concern, Afghanistan, Pakistan, Haiti, Yemen being among severely affected countries.The these nations driven protracted conflicts, political instability, widespread displacement, which [16].In period between 2010 2020, 34 African recounted [17].The ten Ethiopia, (DRC), Somalia, Kenya, Mozambique, South Sudan, Nigeria, Tanzania, Zimbabwe Uganda.Cholera endemic undergo series challenges when neglected, mortality [18], because kill within hours if left untreated [19] economic instability commerce [20]. high-risk communities face exclusion marginalization [21].

Public involvement has proven pillar prevention, educating local response efforts ensures awareness [29]. Alternatively, addressing underlying providing emergency assistance minimize displacements people cross-border [30].To further mitigate beyond, imperative stakeholders, governments, community, non-governmental organizations prioritize [31]. would help incorporate successful strategies other regions. Ahmed [32] reported March 2017, team specialists Asian at risk various representatives WHO came Vietnam share progress terms interventions water, (WASH), surveillance oral vaccine use [32]. multi-sectoral collaboration integrating CDC's "One Health" approach, broader contributing outbreaks. Besides, crucial explore coverage indicators effect cholera.

Cholera is a virulent infectious disease caused by the Gram-negative, comma-shaped bacteria Vibrio cholerae , after ingesting contaminated food and/or water. If left untreated, it can kill within 5 days. Since mid-2021 world has recorded notable increase in seventh cholera pandemic, with high case fatality rate especially Sub-Saharan Africa. Oral vaccines are established but not readily available on market, or if they are, pocket friendly for low-resource-income countries. Hence, advent of green factory biotechnology, plant-derived edible such promising approach to supplement conventional vaccine methods. Human travellers often major transmitters as move from region region. Poor sanitation and inadequate clean water supply services most African countries, coupled insufficient surveillance services, lack early detection facilities, public having ample awareness concerning hygiene. This article highlights epidemiology Africa expounds what drives outbreaks this The discussion provides an in-depth analysis factors leading forsaken drivers, emphasizing economic factors, culture, environmental influences, particularly communities. It presents strategic blueprint that includes health awareness, community participation, government involvement, exploring emerging research tools. By merging these proposals into unified context, collective practical methodology would be tackle impact been sidelined
