The return of cholera: a global threat
Recent WHO data show an alarming increase in cholera cases and deaths, especially in Africa
Cholera, an acute infectious disease caused by the bacterium Vibrio cholerae, is returning to many parts of the world. This epidemic, which appeared to have been eradicated in many regions, poses a serious threat to global public health. The latest data from the World Health Organization (WHO) shows an alarming increase in cases and deaths, especially in Africa.
An epidemic with deep roots
Cholera epidemics have a long history. Over the centuries, they have plagued numerous populations, causing millions of deaths. The disease, transmitted mainly through contaminated water and food, thrives in conditions of poor hygiene and limited access to drinking water. Although significant progress has been made in the prevention and treatment of cholera, this disease continues to pose a significant challenge for global public health.
The causes of this new wave
The reasons behind the current wave of cholera are multiple and interrelated:
- Climate change: Extreme weather events, such as floods and droughts, contaminate water sources and create ideal conditions for the proliferation of the bacterium Vibrio cholerae
- Armed conflict: Wars and political instability destabilize health systems, cut off the supply of drinking water and hinder response to epidemics
- Poverty and inequality: The poorest communities, often living in poor sanitation conditions and with limited access to health care, are most vulnerable to cholera
- Rapid urbanization: The growth of cities, especially in developing countries, can overload water and sewerage infrastructure, increasing the risk of epidemics
The international response
Faced with this global health emergency, the international community must step up its efforts. WHO has issued an alert and is coordinating the international response, but more investment and collaboration between countries is needed.
Preventing the future
To prevent future cholera outbreaks, a multi-sectoral approach is essential, including:
- Improving access to drinking water and sanitation: This is the fundamental pillar of cholera prevention
- Promoting health education: Informing people about the ways in which the disease is transmitted and preventive measures are essential
- Strengthening health systems: Investing in the training of health personnel, the creation of health facilities and the availability of essential medicines
- Scientific research: Develop new vaccines and therapies to combat cholera and improve epidemiological surveillance
