Initial Engagement and Field Missions

Christos Christou first engaged with (MSF) in 2002, undertaking his initial field assignment as a in , where he provided medical care to migrants and refugees. This early involvement marked his entry into MSF's operational work, focusing on emergency medical support in a domestic context amid Europe's challenges at the time. Following his Greek assignment, Christou deployed to for subsequent missions, including emergency surgery in , where MSF teams were addressing trauma and initiating antiretroviral (ARV) treatment programs for patients. He later served in conflict zones such as , , and the (DRC), handling surgical interventions in resource-limited settings amid ongoing violence and epidemics. In these deployments, spanning the mid-2000s, Christou contributed to MSF's efforts in treating war-wounded patients, managing outbreaks, and expanding access to , reflecting the organization's emphasis on impartial humanitarian action in high-risk environments.

His demonstrated expertise in both operational fieldwork and national-level positioned him for broader recognition, leading to his at MSF's International General Assembly in June 2019.

International Presidency (2019–2025)

Election to Presidency

Dr. Christos Christou, a emergency with extensive field experience in MSF operations, was elected as International President of (MSF) during the organization's International General Assembly in June 2019. The followed the standard MSF process, where the International General Assembly—comprising delegates from MSF's 21 sections worldwide—selects the president for a three-year term, with the option for re-election to a second term; candidates must possess a medical background and cannot hold executive positions or board seats in any MSF section during their tenure. Christou succeeded Dr. Joanne Liu of Canada, who had served an unprecedented two full terms totaling six years, marked by MSF's responses to crises including the Ebola outbreak and the Syrian conflict. His selection highlighted his prior leadership within MSF Greece, where he had progressed from general secretary to vice-president and then president of the board of directors starting in 2012, alongside over 15 years of field missions in regions such as , , and . Christou formally assumed the presidency in September 2019, committing to uphold MSF's principles of medical humanitarian action amid ongoing global challenges like migration crises and armed conflicts. He was re-elected for a second term in 2022, serving until September 2025, when he was succeeded by . Specific vote tallies or competing candidates were not publicly disclosed, consistent with MSF's internal governance practices emphasizing collective decision-making over individualized campaigning.

Leadership During Global Crises

During the , which began in early 2020, Christou advocated for equitable global access to medical tools, stating in March 2020 that MSF teams worldwide would adapt operations to mitigate the virus's impact on humanitarian emergencies while sending solidarity to field staff. He criticized unequal vaccine distribution, asserting in 2021 that "you will not be safe from until everyone is safe from ," and urged governments to prioritize over national stockpiling. Christou repeatedly called for waiving protections on technologies, appealing in March 2021 to nations blocking a proposal and deeming the 2022 TRIPS waiver insufficient in May 2023 as it failed to enable widespread production of treatments and diagnostics. In April 2021, he condemned Brazil's federal response as a "humanitarian ," attributing over 370,000 deaths by then to inconsistent messaging, lack of coordination, and disregard for science-based measures, which politicized and overwhelmed hospitals. Under his leadership, MSF expanded interventions in , including support in , , and , while addressing disruptions to ongoing projects in conflict zones. Amid the 2022 , Christou visited the country in September 2022 to assess needs and discuss expanding MSF's medical aid with authorities, focusing on impartial assistance regardless of affiliation. In October 2022, he issued a letter from reaffirming MSF's commitment to all war-affected populations, including in frontline areas like , where staff reported harrowing conditions and failed civilian evacuations in March 2022. By May 2023, during another visit, he highlighted the war's toll on healthcare infrastructure, with MSF treating thousands for trauma and chronic conditions amid ongoing hostilities. Christou also oversaw MSF's responses to protracted crises, such as Sudan's 2023 civil war, which he described in April 2024 as one of the worst in decades due to massive , famine risks, and inadequate international aid, urging UN action to prevent further deaths. In Yemen, his March 2023 visit underscored eight years of conflict creating a "perfect storm" of , , and bombed facilities, with MSF aiding over 1 million consultations annually. He supported operations in , , and other war zones, emphasizing in 2025 that MSF teams provided care amid escalating violence without political favoritism. At the COP28 climate summit in December 2023, Christou warned that environmental crises exacerbate humanitarian needs in vulnerable regions like and , where MSF observed increased disease outbreaks tied to floods and droughts. Throughout his tenure, these efforts involved deploying over 1,000 staff to crisis zones and advocating for unrestricted humanitarian access, though MSF faced operational challenges from attacks on facilities.

Achievements and Contributions

Humanitarian Impact and Data

Under Christos Christou's leadership as International President of (MSF) from September 2019 to September 2025, the organization sustained large-scale medical humanitarian operations across more than 70 countries, addressing armed conflicts, epidemics, displacement, and healthcare exclusion. MSF teams, comprising approximately 67,000 staff in 2024, focused on impartial aid delivery in high-need contexts, including the wars in (from 2022), (escalating in 2023), (from October 2023), and . In 2024, MSF conducted 16,493,900 outpatient consultations, admitted 1,665,200 patients to facilities, managed 2,473,700 emergency room cases, treated 3,877,100 patients, and vaccinated 1,318,100 individuals against , reflecting the organization's reach during the later phase of Christou's tenure. Additional interventions included care for 584,700 malnourished children in outpatient programs, 209,000 severely malnourished children inpatient, 143,800 cases, and 73,800 instances of . These efforts occurred amid armed conflicts (37% of interventions), internal instability (28%), and stable but underserved settings (35%). In , MSF's response to the conflict starting October 7, 2023, delivered nearly 700,000 outpatient consultations, 188,000 emergency room visits, and around 20,000 surgeries by mid-2025, targeting , infectious diseases, and amid infrastructure collapse. In , deemed one of the decade's worst crises by Christou, MSF performed lifesaving surgeries, emergency cesarean sections, and pediatric treatments for malnutrition and disease in and displaced populations. Operations in involved care and hospital support following Russia's February 2022 , while in , teams aided conflict-affected communities with basic medical services post-2021 coup escalation. Christou's presidency also navigated the COVID-19 pandemic's global effects, with MSF emphasizing equitable access in low-resource areas, conducting field hospitals and vaccination campaigns where state responses faltered. Financially, MSF's program expenditures exceeded €1.5 billion annually by 2024, with 63% of resources directed to field activities, enabling sustained impact despite access restrictions and attacks on healthcare.

Controversies and Criticisms

MSF's Stances on Conflicts and Bias Claims

During Christos Christou's presidency of (MSF) from 2019 to 2025, the organization maintained its foundational principles of neutrality and as outlined in its 1971 , which emphasizes providing aid without discrimination while reserving the right to publicly denounce abuses of when witnessed directly. However, MSF's public stances on armed conflicts, particularly the Israel-Hamas war following the , 2023, attacks, drew accusations of selectivity and from critics, who argued that the group's emphasis on actions overshadowed Hamas's role and casualties. MSF condemned the attacks that killed approximately 1,200 Israelis and took over 250 hostages, describing them as "horrific violence," but subsequent statements focused predominantly on Israel's military response, including claims of "indiscriminate bombings," "," and systematic destruction of Gaza's healthcare infrastructure. In the Gaza context, MSF under Christou issued multiple appeals for an immediate ceasefire and accused Israel of fueling a "humanitarian catastrophe" through restrictions on aid and attacks on medical facilities, reporting over 200 humanitarian worker deaths since October 2023, including 15 MSF staff by October 2025. Christou co-authored an open letter to European leaders in June 2025, charging the EU with "hypocrisy" for enabling Israel's "massacre of Palestinians" while failing to enforce international law, and urged sanctions against Israel. Critics, including NGO Monitor, contended this reflected a violation of MSF's neutrality by systematically omitting Hamas's use of civilian infrastructure, such as hospitals for military purposes, and ignoring Palestinian rocket attacks on Israeli medical sites, with MSF denying evidence of Hamas presence in facilities despite Israeli military findings. Such positions, they argued, aligned MSF with narratives minimizing Hamas's accountability, as evidenced by the group's rare mentions of the October 7 atrocities compared to frequent condemnations of Israeli operations, which totaled over 40,000 Palestinian deaths by mid-2025 per Gaza health authorities. MSF defended its advocacy as a duty to "bear witness" to observed violations, rejecting claims of anti-Israel bias and affirming commitments against antisemitism, while noting operations in Israel post-October 7 to support overwhelmed hospitals. In other conflicts, such as Russia's invasion of Ukraine starting in 2022, MSF criticized attacks on civilian infrastructure without similar bias allegations, treating over 100,000 patients and denouncing both Russian strikes and Ukrainian restrictions on aid. Accusations of institutional bias extended to perceptions of politicization under Christou, with outlets like The Jerusalem Post highlighting MSF's failure to address Hamas's governance in Gaza as a factor in the crisis, potentially undermining the organization's impartiality charter. MSF responded that selective silence on abuses would betray its mandate, though detractors viewed the imbalance—evident in statement volume and funding ties to pro-Palestinian donors—as eroding credibility in polarized conflicts.

Operational and Internal Challenges

During Christos Christou's presidency, (MSF) confronted significant internal challenges related to allegations of institutional racism and discrimination, prompted by an in July 2020 signed by approximately 1,000 current and former staff members. The letter accused MSF of perpetuating and through its programs, citing issues in policies, hiring practices, workplace culture, and pay structures that favored a "privileged white minority." In response, MSF's Core Executive Committee, under Christou's leadership, issued a public commitment to address these concerns via a seven-area covering management, staff rewards, and equity. Christou described the letter as a "catalyst" for reforms, including shifting toward the global south and reviewing policies. Progress on these initiatives proved uneven by 2023. Between 2020 and 2021, MSF recorded 389 reports, including 41 related to , leading to the launch of an Anti-Racism Project and a Rewards Review. Subsequent measures included hiring an International Safeguarding Coordinator in 2023, establishing a global pool of investigators for allegations, and creating an International Contracting Office in October 2023 to standardize contracts. MSF also reviewed over 150,000 media items, removing 2,500 non-compliant photographs by August 2023, and introduced a patient charter emphasizing equitable care. However, underreporting of persisted, and the organization's decentralized structure complicated uniform and strategies. Christou acknowledged that "progress has been uneven… some areas have advanced very little," with and reward policies still misaligned with MSF's values of . An updated action plan was pledged for completion by the end of 2025. Operational challenges intensified during the , with Christou highlighting difficulties in deploying experienced staff amid travel restrictions and border closures, alongside risks to personnel protection and disruptions to supply chains and ongoing projects. These logistics strained MSF's ability to maintain field operations in crisis zones. In 2022, ethical concerns arose over MSF's publication of identifiable photographs of vulnerable patients, such as a 16-year-old victim in Ituri, Democratic Republic of Congo, prompting internal reviews of and protocols under Christou's oversight. A notable operational in 2024 involved the closure of MSF's Access Campaign, which advocated for affordable medicines globally, reducing staff from about 50 to 19 and reallocating resources to a narrower "Access to Products for Healthcare" unit focused on field-specific needs. Critics, including over 100 organizations and 250 individuals such as former MSF leaders, condemned the decision as reflective of "inward, technocratic" leadership that undermined broader advocacy on pricing, , and , potentially causing "catastrophic and irreparable damage" to global efforts. The move was seen as prioritizing operational efficiency over MSF's historical political activism, with concerns raised about the lack of a clear for the new unit and dismissive treatment of allies.
