Impact of War on Public Health in Warzone areas: The Hidden Crisis Beyond the Battlefield





Introduction: War as a Determinant of Public Health

War zones are not only battlegrounds—they are home to millions of civilians whose daily lives are shattered by violence, displacement, and fear. In today’s world, the public health consequences of war have become more severe and longer lasting than ever before. Armed conflicts destroy hospitals, disrupt healthcare supply chains, displace communities, and force skilled health professionals to flee. As a result, essential health services such as maternal care, vaccination, disease control, and chronic disease management can collapse almost overnight.

Contemporary conflicts like the Gaza–Palestine crisis, the Russo–Ukrainian war, and the Sudan and Yemen civil wars highlight how civilian populations bear the brunt of modern warfare. History has shown similar devastation through events like World War II, the Vietnam War, and the prolonged Syrian Civil War, each leaving multi-generational health consequences.

According to the World Health Organization (WHO), up to 90% of conflict-related casualties since World War II have been civilians, reflecting the shift from battlefield combat to wars that target communities, health institutions, and public infrastructure.

War’s impact on health can be categorized into two major pathways:

1. Direct Health Impacts

·       Deaths and injuries from shootings, bombings, and airstrikes

·       Long-term disability from physical trauma

·       Psychological suffering, including PTSD, anxiety, and depression

·       Targeted attacks on hospitals and ambulances, violating international law

2. Indirect Health Impacts

·       Collapse of healthcare systems

·       Outbreaks of infectious diseases due to overcrowding and poor sanitation

·       Severe malnutrition among children and pregnant women

·       Loss of essential maternal, newborn, and child health services

·       Worsening chronic diseases due to interrupted treatment



Indirect impacts often cause more deaths than direct military action, creating a silent crisis that continues long after the war ends.

Current Conflicts Affecting Global Public Health (2024–2025)

Several active conflicts around the world continue to produce humanitarian and public health emergencies:

·       Gaza–Palestine

·       Ukraine

·       Sudan Civil War

·       Yemen Civil War

·       Democratic Republic of Congo (DRC)

·       Afghanistan

·       Haiti

These crises have displaced millions and pushed vulnerable groups—children, women, elderly people, persons with disabilities, adolescents, and newborns—into life-threatening conditions.

Historical Wars That Shaped Our Understanding of Public Health

Looking at major global conflicts helps us understand the long-lasting health implications of war:

·       World War I (1914–1918): Overcrowded trenches contributed to the spread of the Spanish Flu, which killed millions.

·       World War II (1939–1945): The deadliest war in history, leading to the formation of the United Nations and modern international humanitarian law.

·       Vietnam War (1955–1975): Chemical exposure from Agent Orange caused cancer, birth defects, and multi-generational disabilities.

·       Syrian Civil War (2011–present): Massive displacement and near-total collapse of the health system.



Who Suffers the Most? Vulnerable Populations and Global Data

War affects everyone, but its burden falls most heavily on vulnerable groups.

According to WHO, UNHCR, UNICEF, and UN Women (2022–2024):

·       35 million children are displaced by conflict

·       49% of displaced populations are women and girls

·       5 million+ pregnant and postpartum women live in conflict zones with little or no care

·       Newborn deaths triple in war-affected areas

·       25% of refugees include at least one elderly member

·       15% of conflict-affected populations are people with disabilities

·       1 in 5 adolescents experiences severe trauma or depression

·       Men face high risks of forced recruitment, injury, and loss of livelihood Globally, 339 million people need humanitarian assistance because of conflict (OCHA 2024).

How War Destroys Health: Key Pathways of Public Health Breakdown

1. Direct Physical & Psychological Trauma

·       Injuries, amputations, disabilities

·       Psychological trauma and long-term mental health issues

·       High levels of PTSD, especially among children, women, and soldiers

2. Collapse of Health Systems

War cripples essential health services:

·       Hospitals, clinics, and laboratories destroyed

·       Medical supply chains blocked

·       Shortage of doctors, nurses, midwives

·       Interruptions in routine immunization → measles, cholera, TB outbreaks

3. Maternal, Newborn & Child Health Crisis



·       Pregnant women forced to give birth without skilled care

·       Increased neonatal infections and deaths

·       Growth monitoring, antenatal care, and vaccinations halted

4. Water, Sanitation & Hygiene (WASH) Breakdown

·       Damage to water systems → unsafe drinking water

·       Overcrowded shelters → cholera and diarrheal disease outbreaks

·       Poor hygiene → rapid spread of communicable diseases

5. Malnutrition & Famine

·       Blocked supply routes

·       Loss of agriculture and food production

·       Widespread acute malnutrition among children and wome

6. Gender-Based Violence

Conflict zones see:

·       Rape used as a weapon of war

·       Child marriage, trafficking, and exploitation

·       Increased domestic violence in refugee settlements

7. Displacement & Refugee Crisis

Millions are forced to flee:

·       Overcrowded camps lacking healthcare

·       Exposure to extreme weather

·       Increased risk of child labor and trafficking


8. Long-Term Systemic Collapse

Even after fighting stops:

·       Health infrastructure takes decades to rebuild

·       Loss of trained health workers

·       Trauma and disability persist

·       Chronic diseases rise due to lack of consistent care

War not only destroys lives—it destroys the systems that save lives.

Who Helps During War? Key Humanitarian Actors

1. United Nations (UN)

·       Peacekeeping, diplomacy, humanitarian coordination

2. World Health Organization (WHO)

·       Emergency medical teams

·       Rebuilding health systems

·       Disease surveillance

3. UNICEF

·       Child protection and education

·       Nutrition and immunization programs

4. UNHCR

·       Refugee protection

·       Shelter, healthcare, documentation

5. Red Cross / Red Crescent

·       Trauma care

·       Field hospitals

·       Family tracing

6. Major NGOs (MSF, IRC, Save the Children)

·       Emergency surgery

·       Maternal and newborn care

·       Mental health support



How Can Ordinary People Help?

You do not need to be in a war zone to make a difference:

·       Donate to trusted humanitarian organizations

·       Spread awareness through social media, blogs, and community events

·       Support refugees in your community

·       Advocate for peace, human rights, and humanitarian aid

·       Demand governments follow international humanitarian law

Conclusion

War is far more than a political or military crisis—it is a full-scale public health emergency. Its consequences extend beyond explosions and bullets, dismantling entire health systems and leaving millions without basic care. Women, children, the elderly, persons with disabilities, newborns, and pregnant women suffer the most—and often for decades after conflict ends.

Yet even in the darkest times, global solidarity, humanitarian action, and strong public health systems can save lives. Rebuilding requires long-term investment, peacebuilding, and justice. Ultimately, the most lasting solution lies in the pursuit of positive peace—a world where strong institutions, equality, and human dignity are protected.

A healthier, peaceful world is possible when nations prioritize peace, public health, and humanity above conflict.

Child Maltreatment: Breaking the Silence

Image
Childhood is meant to be a time of growth, safety, and love.  Yet for millions of children worldwide, this ideal is shattered by maltreatment—an umbrella term that includes abuse and neglect.  Child maltreatment   (CM) is a global health concern with severe consequences for children, families and society . It refers to any action or failure to act by a parent or caregiver that causes harm, could cause harm, or puts a child at risk of harm. Such experiences can lead to serious emotional, social, and cognitive problems throughout a child’s life. Child maltreatment is not only a violation of human rights, but also a pressing public health concern with lifelong consequences.  According to the World Health Organization  (WHO) “Child maltreatment includes all types of physical and/or emotional ill-treatment, sexual abuse, neglect, negligence and commercial or other exploitation, which results in actual or potential harm to the child’s health, survival, development or...

Health Hazards of Public Transport and Ride-Sharing Drivers in Dhaka City

Image
Dhaka, the bustling capital of Bangladesh, is a city of movement. Every day, millions of people depend on buses, rickshaws, CNG auto-rickshaws, and ride-sharing services to get to work, school, and beyond. At the heart of this movement are the drivers—the invisible engines of urban mobility. Yet, behind the honking horns and endless traffic jams lies a silent crisis: the deteriorating health of Dhaka’s transport workers. Dhaka is currently ranked as the second most polluted city in the world. Air filled with toxic particles, smog from vehicles, and industrial emissions make every breath a health risk. For drivers, who spend more than 12 hours daily on the road, this exposure is far greater than for the average citizen. Long-term inhalation of polluted air has been linked to chronic respiratory diseases, lung cancer, asthma, cardiovascular diseases, and even premature death. Add the stress of navigating Dhaka’s chaotic traffic, and the burden on their health multiplies. According to t...

Spitting and Coughing on the Street: A Habit or a Health Risk?

Image
In every busy corner of our cities — bus stops, markets, footpaths — it’s not uncommon to see people spitting, coughing, or sneezing without covering their mouths. For many, it’s a simple habit or social norm. But in reality, this behavior is a serious public health concern that spreads infections, contaminates the environment, and endangers community health. A Common Yet Overlooked Problem In Bangladesh, especially in Dhaka, where millions of people share crowded spaces daily, the habit of spitting or coughing openly is alarmingly common. According to the World Health Organization (WHO), respiratory infections such as tuberculosis (TB), influenza, and COVID-19 can easily spread through droplets released when an infected person coughs, sneezes, or spits. A single cough can release up to 3,000 droplets, while a sneeze can produce more than 100,000 droplets, traveling several meters through the air. These droplets can stay suspended or settle on surfaces — and anyone touching or inhal...
