Our medical teams in the field provide services that range from basic vaccination campaigns, to maternal and pediatric care, to fighting neglected diseases, to complex surgery. MSF also advocates for affordable, high-quality medicines for the world's poorest people.

See below for more on the types of work that MSF does in more than 60 countries around the globe:

MSF campaigns to challenge the high cost of existing medicines and the absence of treatment for many of the diseases affecting our patients.

Chagas is not as well known as diseases such as malaria or cholera, but it affects between six and seven million people and kills up to 12,500 people each year.

Cholera often breaks out when there is overcrowding and inadequate access to clean water, trash collection, and proper toilets. It causes profuse diarrhea and vomiting which can lead to death.

If contracted, Ebola is one of the world’s most deadly diseases. It is a highly infectious virus that can kill up to 90 percent of the people who catch it, causing terror among infected communities.

Since the beginning of the epidemic, HIV/AIDS has killed some 39 million people. If left untreated, HIV gradually weakens the body’s immune system, usually over a period of up to 10 years after infection.

Kala azar is the second largest parasitic killer in the world—only malaria is more deadly. Along with Chagas disease and sleeping sickness, kala azar is one of the most dangerous neglected tropical diseases (NTDs).

Every year, malaria kills around 660,000 people and infects more than 200 million. Ninety percent of these deaths occur in sub-Saharan Africa.

Eight children die every minute because their diet lacks essential nutrients. They will continue to do so unless food aid changes.

Measles is a highly contagious viral disease and one of the leading causes of death among young children. In 2014, MSF treated 33,700 people for measles and vaccinated 1,513,700 people in response to outbreaks.

Meningococcal meningitis is a highly contagious bacterial form of meningitis—a serious inflammation of the meninges—the thin lining that surrounds the brain and spinal cord.

Doctors Without Borders/Médecins Sans Frontières (MSF) teams have offered trauma-related care around the world, including in the Russian Federation, Sudan (Darfur), Iraq, Congo, and Kashmir.

An obstetric fistula is a hole between the vagina and the bladder or rectum, through which urine or stool leaks continuously. They are devastating injuries that are usually the result of obstructed labor. Fistulas affect more than two million women worldwide.
