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.

From the war-wounded in Jordan, to newborns in Pakistan, to burn patients in Haiti, to people with multi-drug resistant tuberculosis in South Africa and Eastern Europe, we see drug-resistant infections across the globe—including those that can only be treated with the very last lines of antibiotics.

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 with a mortality rate between 25 and 80 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).

Doctors Without Borders/Médecins Sans Frontières (MSF) is challenging a recent Indian court decision to give U.S. pharmaceutical corporation Pfizer a patent it doesn't deserve on its pneumonia vaccine Prevnar13 (PCV13). This decision solidifies Pfizer's monopoly across the globe and prevents vaccine manufacturers in India from making and selling more affordable versions of PCV13 for people in India and other countries where the patent exists until 2026.

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 2015, MSF treated 45,600 people for measles and vaccinated 1,537,400 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.
