In more than 70 countries, Médecins Sans Frontières provides medical humanitarian assistance to save lives and ease the suffering of people in crisis situations.
We set up the MSF Access Campaign in 1999 to push for access to, and the development of, life-saving and life-prolonging medicines, diagnostic tests and vaccines for people in our programmes and beyond.
Based in Paris, CRASH conducts and directs studies and analysis of MSF actions. They participate in internal training sessions and assessment missions in the field.
Based in Geneva, UREPH (or Research Unit) aims to improve the way MSF projects are implemented in the field and to participate in critical thinking on humanitarian and medical action.
Based in Brussels, MSF Analysis intends to stimulate reflection and debate on humanitarian topics organised around the themes of migration, refugees, aid access, health policy and the environment in which aid operates.
This logistical and supply centre in Brussels provides storage of and delivers medical equipment, logistics and drugs for international purchases for MSF missions.
This supply and logistics centre in Bordeaux, France, provides warehousing and delivery of medical equipment, logistics and drugs for international purchases for MSF missions.
This logistical centre in Amsterdam purchases, tests, and stores equipment including vehicles, communications material, power supplies, water-processing facilities and nutritional supplements.
SAMU provides strategic, clinical and implementation support to various MSF projects with medical activities related to HIV and TB. This medical unit is based in Cape Town, South Africa.
BRAMU specialises in neglected tropical diseases, such as dengue and Chagas, and other infectious diseases. This medical unit is based in Rio de Janeiro, Brazil.
Our medical guidelines are based on scientific data collected from MSF’s experiences, the World Health Organization (WHO), other renowned international medical institutions, and medical and scientific journals.
Providing epidemiological expertise to underpin our operations, conducting research and training to support our goal of providing medical aid in areas where people are affected by conflict, epidemics, disasters, or excluded from health care.
Evaluation Units have been established in Vienna, Stockholm, and Paris, assessing the potential and limitations of medical humanitarian action, thereby enhancing the effectiveness of our medical humanitarian work.
MSF works with LGBTQI+ populations in many settings over the last 25-30 years. LGBTQI+ people face healthcare disparities with limited access to care and higher disease rates than the general population.
The Luxembourg Operational Research (LuxOR) unit coordinates field research projects and operational research training, and provides support for documentation activities and routine data collection.
The MSF Paediatric Days is an event for paediatric field staff, policy makers and academia to exchange ideas, align efforts, inspire and share frontline research to advance urgent paediatric issues of direct concern for the humanitarian field.
The MSF Foundation aims to create a fertile arena for logistics and medical knowledge-sharing to meet the needs of MSF and the humanitarian sector as a whole.
A collaborative, patients’ needs-driven, non-profit drug research and development organisation that is developing new treatments for neglected diseases, founded in 2003 by seven organisations from around the world.
Although easy to prevent and treat, cholera affects up to 4 million people worldwide per year, resulting in up to 140,000 deaths.
Caused by a water-borne bacterial infection of the intestine, cholera is transmitted through contaminated food or water, or through contact with fecal matter or vomit from infected people. Cholera can cause severe diarrhoea and vomiting, and rapidly prove fatal, within hours, if not treated. But cholera is very simple to treat – rehydration is key. Most people respond well to oral rehydration salts, which are easy to administer. In more serious cases, intravenous fluids are required. Ultimately, no-one should die of cholera.

Quick facts about cholera
01People at risk
Outbreaks can rapidly spread in over-crowded communities and in dense living conditions, such as refugee camps and in slums, when there is inadequate access to clean water, waste collection, and proper toilets. People being displaced, destruction of infrastructure, or a lack of public services can mean cholera is a serious risk in the aftermath of a natural disaster or during a conflict. Both drought and flooding can increase the risk for cholera. Drought decreases the available amount of clean water, forcing people to use contaminated water. Flooding can spread the bacteria and contaminate water sources.
02Simple to treat
Cholera is relatively simple to treat in most cases, with people with mild to moderate forms usually able to recover through treatment with fluids and oral rehydration salts, which are easy to administer. People who are severely dehydrated may need intravenous fluids and hospitalisation. In these cases, they should be admitted to a Cholera Treatment Centre (CTC). Without treatment, the mortality rate can reach 50 per cent. With proper medical care, it's around 0.2 per cent.
03Clean water & sanitation
Cholera occurs in areas with poor access to sanitation and unsafe drinking water - so providing people with clean drinking water and proper sanitation facilities is vital to preventing and curbing any outbreaks. Our water and sanitation teams provide people with sachets to purify water, truck clean water in, and install, fix and clean out sanitation facilities such as toilets in affected areas. Informing people about good hygiene practices such as washing hands, using clean toilets, and using only clean water to drink and wash food, can also curb outbreaks of the disease.
04Vaccination
Vaccines against cholera are orally administered, which is practical for mass vaccination and does not require medical personnel. Of the two vaccines used for mass vaccination, one does not even need a cold chain. We know that one dose of a vaccine provides sufficient protection and can reduce or prevent transmission of the disease, but vaccination officially requires two doses. However, in October 2022, a WHO-hosted vaccination coordination group – of which MSF is a member – exceptionally approved one-dose strategy, given a shortage of cholera vaccines and the high number of outbreaks around the world.
05Rapid response
A rapid response is vital to containing the spread of a cholera outbreak. Quickly putting in place health promotion activities - educating people about how to help to limit the spread - plus water and sanitation activities, establishing treatment centres and vaccinating in an emergency response can help limit how far an epidemic spreads and reduce the number of people who fall sick or die.
06Model of care
The design of the Cholera Treatment Centre (CTC) by MSF was a significant contribution to cholera epidemic response. A CTC is set up outside of the main hospital to prevent the spread of the disease and is fully autonomous. In open settings, with spread-out populations, treatment needs to be as close as possible to affected populations. Care can be decentralised to smaller-scale CTCs known as cholera treatment units and oral rehydration solution (ORS) points, supported by mobile teams.

Cholera outbreaks resurgence
A resurgence of cholera outbreaks
In 2023, 30 countries recorded cases of cholera. MSF teams responded to cholera outbreaks in more than 10 countries, including in Lebanon, Haiti, Syria and DRC; in many of these countries, the situation is worrying. But why are we seeing a resurgence of cholera outbreaks?
MSF often responds to outbreaks of cholera in the countries we work. But how do we set up our cholera treatment centres to ensure our patients get the best care possible - and that the disease doesn't spread? Learn more about the layout and activities of an MSF cholera treatment centre in this interactive guide.
