The History of Cholera

From Ancient Times to Modern Eradication Efforts

A cholera outbreak in the South African capital of Pretoria in May 2023 claimed the lives of 10 people, with 95 people being admitted to a local hospital in the Gauteng region with symptoms of cholera such as diarrhoea, stomach cramps, and nausea. From those 95 admissions, at least 19 were confirmed to be cholera. While Cholera is not endemic in South Africa, the country has reported a number of cases of the disease off the back of outbreaks in nearby Mozambique and Malawi, two of the heaviest affected countries in 2023, according to the UN. The WHO has pointed to poverty, conflict and climate change as reasons for a rise in cases of Cholera. With that in mind, let’s take a closer look at the history of cholera, both globally and in Ireland, and what is being done to curb the effects of cholera worldwide.

What is Cholera

Cholera is a highly contagious and deadly bacterial infection that has plagued humanity for centuries. It is caused by the bacterium Vibrio cholerae, which spreads through contaminated water and food, leading to severe diarrhoea and dehydration.

This blog delves into the history of cholera worldwide, highlighting its devastating impact and the strides made in its prevention and treatment. Additionally, it provides a specific focus on the history of cholera in Ireland, where the disease left an indelible mark on the nation’s history many years ago.

Cholera has a long history, with evidence of outbreaks dating back to ancient times. The earliest known records of cholera-like symptoms can be traced to ancient Sanskrit writings in India around the 5th century BCE. However, it was not until the 19th century that cholera gained worldwide attention due to its explosive epidemics and high mortality rates.

History of Cholera – 1st Recorded Pandemic

The first recorded pandemic of cholera emerged in 1817, originating in the delta of the Ganges River in India. From there, the disease rapidly spread across Asia, Europe, and the Americas, causing millions of deaths. Its ability to travel swiftly along trade routes and its association with poor sanitation and overcrowding in urban areas fuelled its devastating impact.

Cholera in Ireland

Ireland has its own history with cholera. In the mid-19th century, cholera reached Ireland, leaving a significant mark on the country’s history. The first major outbreak occurred in 1832 in Sligo at a time when Sligo was the second busiest port on the west coast after Limerick. Official numbers state a death toll of 643 deaths in a population of approximately 15,000. Actual figures are believed to have been much higher as only deaths at Fever Hospital were recorded.

Subsequent epidemics struck the island in 1849, 1853, and 1866. The Great Famine, a period of mass starvation and emigration in Ireland between 1845 and 1852, exacerbated the spread of cholera. The famine weakened the population, making them more susceptible to infections, and the lack of adequate sanitation and healthcare infrastructure further facilitated the disease’s transmission.

During the cholera outbreaks in Ireland, the disease claimed the lives of tens of thousands of people, worsening the already dire social and economic conditions. The impact was particularly severe in the overcrowded urban areas, where poverty and squalor were rampant. The lack of proper sanitation systems and clean drinking water exacerbated the spread of the disease, making it challenging to control.

Eradication Efforts

Initial efforts to combat cholera in Ireland were slow and inadequate. It was not until the late 19th century that improvements in public health infrastructure and hygiene practices began to have a significant impact. The establishment of water and sewage systems, along with the introduction of proper waste disposal methods, helped curb the spread of the disease.

Globally, the fight against cholera gained momentum in the 20th century. The discovery of antibiotics and the development of oral rehydration therapy (ORT) revolutionized cholera treatment. ORT, a simple and cost-effective solution, became a cornerstone in managing cholera-related dehydration and drastically reduced mortality rates.

Today, global efforts to eradicate cholera continue. Organizations like the World Health Organization (WHO) and UNICEF work with governments and local communities to improve sanitation, access to clean water, and healthcare infrastructure in regions prone to cholera outbreaks. Vaccines have also been developed, offering protection against cholera, and reducing the risk of large-scale epidemics.

In conclusion, the history of cholera worldwide is marred by its devastating impact on communities and nations. From ancient times to the modern era, cholera has claimed countless lives and caused immense suffering. In Ireland, cholera outbreaks during the 19th century further compounded the challenges faced by a nation already grappling with poverty and famine. However, advancements in public health, sanitation, and medical interventions have significantly reduced the disease’s burden. Today, with concerted global efforts, we strive towards eradicating cholera and ensuring a safer, healthier world for all.
