  • Due to the rising number of cholera cases in the area, cholera vaccine shortages are a serious concern for African countries.
  • In five African countries, there have been 27,300 new cases of cholera since the year 2023, with 687 deaths.
  • According to the WHO (World Health Organization), cholera epidemics may become more frequent as a result of climate change because the bacteria that cause the disease can grow faster in warmer water.

About cholera:

  • It is a bacteria-caused potentially fatal infectious disease and a menace to the public's health.
  • Vibrio cholera infections of the gut result in cholera, an acute diarrheal sickness.
  • Although the illness is mostly mild or symptomless, it can occasionally be severe.


  • Leg cramps, nausea, and excessive watery diarrhea.
  • Cholera can be contracted by drinking contaminated water or eating food that has been exposed to the cholera bacterium.
  • In locations where sewage and drinking water are not properly treated, the disease can spread quickly.
  • There are now three oral cholera vaccines (OCV) approved by the WHO: Dukoral, Shanchol, and Euvichol-Plus.
  • For complete protection, all three immunisations require two doses.

What efforts are being made to stop cholera?

  • Ending Cholera: A Global Roadmap to 2030, a global cholera control strategy, was introduced in 2017. Its goal is to reduce cholera mortality by 90%.

  • Global Task Force for Cholera Control (GTFCC): In order to support WHO's efforts to eradicate cholera, the GTFCC was reactivated.
  • The GTFCC's mission is to promote the increased application of research-supported cholera control measures.
