The Hidden Global Health Crisis Accelerated by War

Wherever bombs fall, civil infrastructure collapse in their wake. If visible damage draws attention, another quieter danger spreads in the shadow of conflicts. Where care is scarce and hygiene conditions deteriorate, some bacteria find an ideal soil for mutating, strengthening and resisting treatments. Resistance to antimicrobials is not only born in laboratories or overloaded hospitals, it also feeds on the chaos of war.

Lands of war, hospitals are rarely spared. Driven of drinking water, electricity or staff, these establishments see their response capacities collapse. In Gaza, two thirds of hospital infrastructures have become inoperative, leaving overwhelmed caregivers, patients without suitable treatment and infections spread at high speed. The researcher Yara M. ASI, an expert in public health, stresses that 34% of hospital water samples analyzed was already unfit for consumption even before the 2023 strikes.

In this environment saturated with dust, unnamed bodies and wounded pending, microbes find ideal conditions. During the 2018 demonstrations in Gaza, the European Gaza Hospital observed an explosion of multidusive bacteria, especially on the wounded wounds. According to a study published in The Lancet, some strains of Pseudomonas and Acinetobacter saw their resistance to current antibiotics increase up to 300% in a few months.

The phenomenon is not limited to a territory. In Syria, the conflict has disorganized the entire medical system, resulting in the free movement of antibiotics without a prescription in more than 85% of cases, according to an analysis of the Revue Communications Medicine. This uncontrolled overuse, in contexts where the precise diagnosis is often impossible, opens the way to an accelerated selection of resistant bacteria.

Why conflicts promote antimicrobial resistance

The link between war and antimicrobial resistance is not a chain of isolated causes, but a global mechanism. When antibiotics become the last bulwark to contain epidemics in ravaged areas, their use is generalized. This was the case in Yemen, where the largest cholera epidemic in recent history broke out in the middle of the civil war. Faced with the emergency, doctors massively administered macrolides. According to a report by the magazine Phys.org, the strains of Vibrio Cholerae quickly acquired a plasmid giving them resistance to numerous first -line treatments.

War is not content to destroy buildings. It also destroys supply chains, interrupts vaccination campaigns and pushes caregivers to make impossible choices. In the affected territories, every minute is devoted to saving a life rather than respecting rigorous antibiotic protocols. This constant tension prevents any long -term control strategy.

In parallel, the bombings contaminate soils and water tables. Heavy metals, released en masse, select microorganisms capable of surviving in these hostile environments, including Acinetobacter Baumannii, sadly famous for its nosocomial infections. In Ukraine, in 2022, this pathogen showed up to 72% resistance to meropenème, an antibiotic of the last resort.

An invisible threat that crosses borders

Conflicts move millions of people, and with them, the bacteria they have. The World Health Organization recalls that people who are refugee after a conflict often require hospital care in their host country. In Germany, Ukrainian patients transferred after war injuries had strains of Klebsiella pneumoniae resistant to all the treatments tested. These cases have forced hospitals to systematically isolate patients from war areas.

This phenomenon is not new. In Afghanistan, Iraq or Libya, the wounded repatriated were regularly the source of serious nosocomial infections, often due to multi-resistant bacteria such as acinetobacter or strains producing carbapenemas. The JIDC scientific publication shows that the progression of cholera in Yemen almost exactly follows the map of violence and population displacements.

Political borders are not organic barriers. When the laboratories are destroyed, the data disappears. The absence of microbiological monitoring in war areas therefore makes resistance to antimicrobials practically invisible. And this statistical silence prevents health systems from the rest of the world from anticipating the arrival of new strains, sometimes incurable.

Over the conflicts, a truth is essential. Modern wars do not only leave ruins behind them. They also leave mutant, invisible, persistent germs, carried by weakened bodies, in a globalized world which still too often ignores that the microbial front knows neither armistice nor border.
