Cholera Today: A Global Perspective on Inequality and Preventative Measures

Cholera, a waterborne disease caused by the bacterium Vibrio cholerae, persists as a significant public health challenge in numerous countries worldwide, particularly affecting marginalized communities. Despite the eradication of cholera in regions with advanced sanitation systems, the disease continues to afflict at least 47 countries, resulting in an estimated 2.9 million cases and 95,000 deaths annually globally.

Inequalities in access to safe drinking water and sanitation facilities exacerbate the spread of cholera, disproportionately impacting the poorest and most vulnerable populations within affected countries. The transmission of cholera typically occurs through faecally contaminated water or food, with its short incubation period of 2 hours to 5 days facilitating rapid escalation in case numbers and mortality rates.

Cholera control necessitates a dual approach, encompassing both emergency response to outbreaks and long-term development efforts, particularly in endemic regions. Key interventions for effective cholera prevention and control include enhanced epidemiological and laboratory surveillance, universal access to safe water and basic sanitation, community engagement for behavioral changes, prompt access to treatment such as Oral Rehydration Solution (ORS) and antibiotics for severe cases, and protection through safe and effective oral cholera vaccines (OCV).

However, despite ongoing efforts, the persistence of cholera in endemic areas and the recurrent nature of outbreaks underscore the inadequacies of current control strategies. While emergency response measures mitigate immediate threats, they often fall short in addressing the root causes of cholera transmission and preventing future outbreaks. Long-term Water, Sanitation, and Hygiene (WASH) programs are insufficiently prioritized and fail to adequately target high-risk areas, perpetuating the cycle of cholera transmission.

Global disparities in access to safe water and sanitation further compound the challenge of cholera prevention. Approximately 844 million people lack access to basic drinking water sources, over 2 billion consume water contaminated with fecal matter, and 2.4 billion lack basic sanitation facilities . Notably, households in cholera-affected countries exhibit significantly lower access to basic water and sanitation services compared to the global average, exacerbating vulnerability to waterborne diseases like cholera.

Despite these challenges, cholera remains a preventable disease, with existing tools and interventions offering hope for its eventual eradication. Proactive and targeted measures, including investments in WASH infrastructure, strengthening health systems, and widespread utilization of OCVs in high-risk populations, are urgently needed to curb the spread of cholera and alleviate the burden on affected communities.

In conclusion, cholera persists as a stark reminder of global health inequalities, with marginalized populations bearing the brunt of its impact. Addressing the root causes of cholera transmission through comprehensive and sustainable interventions is imperative to achieve the ultimate goal of eradicating this preventable disease and ensuring equitable access to health for all.

Understanding Oral Cholera Vaccines: A Comprehensive Overview

Oral cholera vaccines (OCV) have emerged as crucial tools in the global fight against cholera, offering protection to individuals residing in endemic regions, during humanitarian crises, and amidst cholera outbreaks. As of now, three vaccines hold pre-qualification from the World Health Organization (WHO): Dukoral®, Shanchol™, and Euvichol-Plus® [4].

Dukoral®, the pioneer among the three, requires the administration of two doses for full protection. This vaccine, primarily intended for travelers, necessitates a buffer solution and clean water for ingestion, with a minimum interval of 7 days and a maximum of 6 weeks between doses. Children aged 2–5 years may require a third dose for optimal protection, with the vaccine conferring immunity for up to 2 years post-vaccination.

In contrast, Shanchol™ and Euvichol-Plus®, produced by different manufacturers but sharing the same vaccine formula, offer a buffer-free administration. These vaccines, suitable for individuals aged 1 year and above, mandate a minimum interval of 2 weeks between doses. Two doses of Shanchol™ and Euvichol-Plus® provide protection against cholera for at least 3 years, while a single dose offers short-term immunity.

A notable feature of Shanchol™ is its prequalification for use in a controlled temperature chain, enabling storage at temperatures beyond the conventional cold chain requirements (+2°C to +8°C) for a limited period under monitored conditions. This innovative approach facilitates vaccine distribution and expands access to remote or resource-constrained regions.

Both Shanchol™ and Euvichol-Plus® are integral components of mass vaccination campaigns orchestrated through the Global OCV Stockpile, with support from Gavi, the Vaccine Alliance. These campaigns, which have witnessed the deployment of over 145 million doses since the inception of the stockpile, target areas grappling with cholera outbreaks, humanitarian crises, and endemic hotspots.

The WHO’s position paper on vaccines against cholera, issued in August 2017, underscores the strategic deployment of OCV in endemic areas, humanitarian crises, and outbreaks, supplementing existing prevention and control measures. Importantly, vaccination initiatives must not compromise the delivery of other critical health interventions. Instead, they should complement broader cholera control strategies, ensuring a holistic approach to disease management.

Oral cholera vaccines represent indispensable tools in mitigating the global burden of cholera. With their efficacy validated through mass vaccination campaigns and their integration into comprehensive cholera control programs, OCVs offer hope for reducing cholera-related morbidity and mortality worldwide. Continued investment in vaccine research, production, and distribution is essential to sustain progress towards the ultimate goal of cholera eradication.
