Battling Cholera: Azerbaijan's Fight And Future Plans

Cholera is a waterborne disease caused by the bacterium Vibrio cholerae. It is an acute intestinal infection that can cause severe watery diarrhoea and even death within hours if left untreated. The disease is closely linked to inadequate access to clean water and sanitation facilities.

In Azerbaijan, cholera has been detected in environmental waters, including drinking water reservoirs, posing a potential health risk to the population due to the limited and insufficient treatment of water in the country. The occurrence of cholera in the country has been linked to seasonal changes, with higher temperatures in the warmer months leading to an increased detection of Vibrio cholerae.

To address the issue of cholera in Azerbaijan, efforts have been made to improve water and sanitation infrastructure and implement public health measures. These include routine monitoring of environmental waters, especially drinking water reservoirs, to ensure public health safety. Additionally, health education and environmental control are critical for the prevention of cholera.

On a global scale, the World Health Organization (WHO) has launched a strategy called Ending Cholera: A Global Roadmap to 2030, which aims to reduce cholera deaths by 90% and eliminate cholera in 20 countries by 2030. This strategy includes early detection, rapid response, and a targeted multi-sectoral approach to prevent cholera recurrence.

Cholera is transmitted through contaminated food and water

Cholera is an acute diarrhoeal disease that can kill within hours if left untreated. It is transmitted through the ingestion of contaminated food or water.

Cholera is caused by the bacterium Vibrio cholerae, which was discovered by German bacteriologist Robert Koch in 1883. It is a gastrointestinal disease that remains a persistent problem in many countries, including Azerbaijan. The disease is endemic in the Islamic Republic of Iran, which borders Azerbaijan.

Vibrio cholerae has been detected in environmental waters in Azerbaijan, including drinking water reservoirs. The presence of V. cholerae in these reservoirs, which are the source of municipal drinking water, poses a potential health risk to the population due to the limited and insufficient treatment of water in the country.

The transmission of cholera is closely linked to inadequate access to clean water and sanitation facilities. Conflict, unplanned urbanization, and climate change all increase the risk of cholera.

To prevent and control the spread of cholera and other waterborne diseases, it is critical to provide safe water and basic sanitation and to promote hygiene practices. Oral cholera vaccines should also be used in conjunction with improvements in water and sanitation.

The disease is endemic in Azerbaijan

Cholera is a severe and acute diarrhoeal disease caused by the bacterium Vibrio cholerae. It is a disease of poverty, affecting people with inadequate access to safe water and basic sanitation. It is transmitted through the ingestion of contaminated food or water. The disease is endemic in Azerbaijan, where it has been detected in environmental waters, including drinking water reservoirs.

Azerbaijan has a history of cholera outbreaks, with the bacterium detected in both marine and freshwater habitats. The occurrence of cholera is linked to environmental factors such as water temperature, salinity, rainfall, and the presence of plankton. Inadequate water treatment, insufficient sanitation, and a leaking water distribution network contribute to the spread of cholera in the country.

To address the endemic nature of cholera in Azerbaijan, various measures are being implemented. These include improving access to healthcare services, especially in rural areas, and enhancing disease surveillance systems. Efforts are also being made to control other common diseases, such as tuberculosis, diabetes, and obesity, through education, prevention, and treatment initiatives.

The long-term solution for cholera control lies in economic development and universal access to safe drinking water and sanitation. The World Health Organization (WHO) has developed a global strategy, "Ending Cholera: A Global Roadmap to 2030," which aims to reduce cholera deaths by 90% and eliminate cholera in 20 countries by 2030. This strategy includes early detection, rapid response, targeted multi-sectoral approaches, and improved water, sanitation, and hygiene (WASH) practices.

The detection and treatment of cholera in Azerbaijan are crucial aspects of controlling the disease. Rapid diagnostic tests and laboratory confirmation are used to detect cholera, while oral rehydration solutions, intravenous fluids, and antibiotics are administered for treatment. Community engagement and education are also essential components of cholera control, empowering people to adopt good hygiene practices and make healthier lifestyle choices.

The country has a history of cholera outbreaks

Azerbaijan has a history of cholera outbreaks. The country has experienced cholera during every pandemic since 1816. The disease is caused by the bacterium Vibrio cholerae, which is transmitted through the ingestion of contaminated food or water.

Vibrio cholerae is a motile, Gram-negative curved rod belonging to the family Vibrionaceae. While there are around 200 recognised O serogroups of Vibrio cholerae, only two—O1 and O139—cause outbreaks. The O1 serogroup has been responsible for all recent outbreaks, while O139 has only been identified in sporadic cases and has never been found outside Asia.

Cholera can be either endemic or epidemic. A cholera-endemic area is one where confirmed cases were detected in the last three years, with evidence of local transmission. A cholera outbreak or epidemic can occur in both endemic and non-endemic countries.

The detection of a suspected cholera case is based on clinical suspicion in patients aged two years and older with acute watery diarrhoea and severe dehydration or dying from acute watery diarrhoea. While most people infected with Vibrio cholerae are asymptomatic, the bacteria are present in their faeces for 1–10 days after infection and are shed back into the environment, potentially infecting others.

A multifaceted approach is key to controlling cholera and reducing deaths. This includes surveillance, water, sanitation, hygiene, social mobilisation, treatment, and oral cholera vaccines.

The long-term solution for cholera control lies in economic development and universal access to safe drinking water and basic sanitation. In the short term, rapid access to treatment is essential during a cholera outbreak. Oral rehydration should be available in communities, in addition to larger treatment centres that can provide intravenous fluids and 24-hour care. With early and proper treatment, the case fatality rate should remain below 1%.

Cholera is a disease of poverty, affecting people with inadequate access to safe water and basic sanitation

The World Health Organization (WHO) estimates that there are 2.9 million cholera cases and 95,000–120,000 deaths worldwide each year. However, due to limited epidemiological surveillance and laboratory capacity, as well as social, political, and economic disincentives, the global burden of cholera is largely unknown, with many cases going unreported.

Cholera disproportionately affects sub-Saharan African countries, and inadequate access to safe water and sanitation is a significant contributing factor. Inadequate handwashing, lack of clean drinking water, and lack of latrines are major determinants of cholera outbreaks. For example, in a 2019 cholera outbreak in the Somali region of Ethiopia, drinking unsafe pipe water, not having a household-level toilet/latrine, handwashing infrequently after using the toilet, and not using water purification methods were identified as significant risk factors.

To prevent and control cholera, it is crucial to improve access to clean drinking water, promote proper handwashing practices, and ensure proper sanitation and hygiene. During cholera outbreaks, the distribution of water purification tablets, soap, and hand sanitizers is essential, along with the provision of healthcare and outbreak response.

Long-term goals in cholera-affected areas should include comprehensive water and sanitation strategies. The strategic role of a multi-sectoral approach is vital in designing and implementing effective public health interventions to prevent and control cholera outbreaks.

The Azerbaijani government is taking steps to improve water and sanitation facilities

The government is working to improve access to safe drinking water and basic sanitation, which is critical to preventing and controlling the transmission of cholera and other waterborne diseases. This includes implementing long-term sustainable solutions to ensure the use of safe water and basic sanitation, as well as promoting good hygiene practices.

The government is also encouraging the use of oral cholera vaccines in conjunction with improvements in water and sanitation to control cholera outbreaks and prevent them in high-risk areas. These measures are in line with the global strategy on cholera control, "Ending Cholera: A Global Roadmap to 2030," which aims to reduce cholera deaths by 90% and eliminate cholera in 20 countries by 2030.

The Azerbaijani government recognizes the importance of surveillance and is strengthening its disease surveillance systems to rapidly detect and respond to cholera outbreaks. This includes monitoring the occurrence of Vibrio cholerae in natural waters, including sources of municipal water, as the presence of the bacterium in water reservoirs poses a potential health risk to the population.

By taking these comprehensive steps, the Azerbaijani government is committed to improving water and sanitation facilities to prevent the spread of cholera and protect the health and well-being of its citizens.
