Aid worker health

Maintaining Your Own Health on Deployment

To be effective in humanitarian work, you must protect your own physical and mental health. Field work after conflict, disaster, displacement or disease outbreaks can expose aid workers to exhaustion, unsafe water, poor sanitation, infectious disease, stress, isolation, heat, mosquitos, animals and difficult decisions.

Listen to the health and security briefing

The most important health advice on a mission is often local, current and specific. Your organisation’s security focal point, medical adviser, health coordinator, WASH lead, logistics team, line manager and experienced local colleagues may know things that no public travel page can tell you.

Follow instructions to the letter. If you are told not to drink from a water source, not to walk after dark, not to touch animals, not to use a route, not to eat from a certain place, not to travel alone or not to attend a site without clearance, treat that as a health instruction as well as a security instruction.

Briefings are based on local incidents, clinic access, evacuation routes, disease alerts, road conditions, security analysis, accommodation quality, vehicle availability and duty-of-care procedures. Ignoring them can put you, your colleagues and local partners at risk.

Before you go

Good field health starts before departure. Many problems become harder to manage once you are remote, exhausted, under security restrictions or dependent on limited local services.

  • Book a travel health appointment early.
  • Check routine vaccinations and destination-specific vaccines.
  • Discuss malaria prophylaxis where relevant.
  • Check whether rabies pre-exposure vaccination is recommended.
  • Carry enough prescribed medication for the deployment and buffer time.
  • Keep medication in original packaging where possible.
  • Carry copies of prescriptions and relevant medical letters.
  • Check insurance, evacuation cover and emergency contact procedures.
  • Know the organisation’s medical reporting route.
  • Update emergency contacts and share your itinerary securely.
  • Pack oral rehydration salts, basic first aid and personal hygiene supplies.
  • Check glasses, dental work and chronic conditions before travel.

Food, water and stomach illness

Diarrhoea, dysentery, vomiting and dehydration can stop an aid worker from functioning within hours. In some places, unsafe water and poor sanitation are among the biggest daily health risks.

Use the water source approved by your organisation or accommodation. If you are told to use bottled, filtered, boiled, chlorinated or otherwise treated water, do it every time. Remember that ice, salad washing, tooth brushing and re-used bottles can also expose you.

Practical habits

  • Wash hands with soap after toilets and before eating.
  • Use alcohol hand rub when soap and safe water are not available.
  • Drink only approved water sources.
  • Avoid ice unless you know it was made from safe water.
  • Choose food that is cooked thoroughly and served hot.
  • Be careful with raw salad, unpeeled fruit, street food and buffets in hot climates.
  • Keep oral rehydration salts available.
  • Report blood in stool, fever, severe pain or persistent diarrhoea early.

Malaria and mosquitoes

In malaria areas, prevention is not one thing. It is a system: correct medication where recommended, bite avoidance, treated nets or screened rooms, clothing, repellent and rapid action if fever develops.

No antimalarial drug is completely protective, so tablets do not replace bite prevention. Use the prevention plan given by your travel health clinician or organisation and do not stop medication because colleagues say it is unnecessary.

Field routine

  • Take chemoprophylaxis exactly as prescribed where recommended.
  • Use repellent on exposed skin.
  • Wear long sleeves and trousers at peak biting times.
  • Sleep under an insecticide-treated net or in screened/air-conditioned accommodation where possible.
  • Check nets for holes and tuck them in properly.
  • Remove standing water around accommodation where feasible.
  • Seek medical advice urgently for fever during or after time in a malaria area.

Animals, scratches and rabies

Avoid dogs, cats, monkeys, bats and other mammals. A small bite, scratch or lick on broken skin can become a serious medical exposure in rabies-risk countries.

Do not pet animals, rescue animals, feed animals, play with puppies, pick up injured animals or assume a friendly animal is safe. Rabies is almost always fatal once symptoms appear, but vaccination and urgent post-exposure care can prevent it when given in time.

If bitten or scratched

  • Wash the wound immediately with soap and running water for at least 15 minutes if possible.
  • Apply an appropriate disinfectant if available.
  • Report the exposure to your manager and medical focal point.
  • Seek urgent medical advice about rabies post-exposure prophylaxis.
  • Do not wait to see whether the wound looks serious.

Daily routine in the field

A stable routine protects health when the environment is unstable. The aim is not perfection. The aim is to remove repeated avoidable risks.

Morning

  • Check security and movement instructions.
  • Drink safe water before travel.
  • Eat something reliable before field visits.
  • Apply sunscreen and repellent as needed.
  • Carry water, snacks, medication and emergency contacts.

During the day

  • Use hand hygiene before eating.
  • Avoid unapproved water or food.
  • Keep breaks in the plan.
  • Monitor heat, fatigue and stress.
  • Report health concerns early.

Evening

  • Wash and inspect minor cuts.
  • Take medication as scheduled.
  • Check mosquito protection.
  • Eat properly and rehydrate.
  • Stop work at a reasonable point where possible.

Mental health and burnout

Aid work can expose you to distress, grief, moral pressure, insecurity, long hours, organisational frustration and repeated stories of harm. Mental health is not separate from operational performance.

Burnout often develops quietly: irritability, cynicism, numbness, loss of empathy, poor sleep, risk-taking, isolation, errors, overwork, anger, guilt or feeling that you alone must hold the response together.

Protective actions

  • Use supervision and peer support before crisis point.
  • Keep some contact with people outside the mission.
  • Take rest days and leave when available.
  • Do not use alcohol or substances to manage trauma or sleep.
  • Separate urgency from constant availability.
  • Ask for support after critical incidents.
  • Raise workload concerns early and specifically.

Sleep, fatigue and overwork

Humanitarian culture can reward overwork, but chronic fatigue reduces judgement, patience, driving safety, safeguarding awareness, security discipline and decision quality.

If the mission is truly life-saving and time-critical, there may be intense periods. But an intense period needs recovery. A team that works without limits eventually becomes unsafe.

  • Agree realistic working hours with your manager.
  • Protect at least one proper recovery window each week where possible.
  • Avoid unnecessary late-night email loops.
  • Do not drive tired if alternatives exist.
  • Use handover notes so work does not depend on one exhausted person.
  • Take leave before you are forced into medical evacuation or breakdown.

Exercise and movement

Movement helps sleep, stress regulation, circulation, strength and mood. In insecure or restricted environments, exercise may need to be modest and private.

Do not ignore security rules to exercise. If walking, running or gyms are not safe, use low-profile options in accommodation: stretching, bodyweight exercises, mobility work, resistance bands or short indoor routines.

Heat

Heat illness can develop quickly. Drink safe water, replace salts when sweating heavily, plan shade, pace movement and seek help for confusion, fainting, severe headache or stopped sweating.

Cold

Cold exposure affects sleep, morale and health. Keep dry layers, protect feet, change wet clothes, eat enough and report numbness, shivering that will not stop or confusion.

Dust, smoke and air quality

Dust, burning waste, smoke, mould and poor ventilation can aggravate breathing problems. Follow local advice on masks, indoor air, vehicle windows and high-exposure tasks.

Sexual health, boundaries and safeguarding

Humanitarian settings involve power imbalances, stress, isolation and vulnerability. Protecting health also means protecting boundaries, consent, dignity and safeguarding standards.

  • Follow your organisation’s safeguarding and sexual misconduct rules.
  • Do not enter relationships that exploit power, dependency or vulnerability.
  • Carry condoms if sexual activity is possible.
  • Seek urgent medical advice after sexual assault, exposure risk or condom failure.
  • Know the pathway for post-exposure prophylaxis where relevant.
  • Report safeguarding concerns through the correct channel.

When to seek medical advice

Seek help early. Waiting because you do not want to create work for others can turn a manageable issue into a medical evacuation, outbreak risk or security problem.

  • Fever in or after a malaria area.
  • Blood in stool or severe diarrhoea.
  • Persistent vomiting or dehydration.
  • Animal bite, scratch or saliva exposure.
  • Needlestick or blood/body-fluid exposure.
  • Breathing difficulty or chest pain.
  • Confusion, fainting or collapse.
  • Heat illness symptoms.
  • Wounds that are dirty, deep, infected or not healing.
  • Severe anxiety, panic, intrusive memories or suicidal thoughts.
  • Sexual assault or sexual exposure risk.
  • Any symptom your organisation tells you to report immediately.

After deployment

Health monitoring does not end when you leave the field. Some infections, stress reactions and adjustment difficulties appear after return.

  • Complete any post-travel medical screening required by your organisation.
  • Seek medical advice for fever, diarrhoea, weight loss, rash or unusual symptoms after return.
  • Tell clinicians where you have travelled and what work you did.
  • Continue malaria medication after travel if prescribed.
  • Use decompression time if available.
  • Watch for re-entry stress, irritability, numbness or sleep problems.
  • Record lessons for your next deployment.

FAQs

What is the most important health habit for aid workers?

Consistency. Small daily routines around safe water, hand hygiene, food choices, sleep, malaria prevention, rest and early medical reporting are more protective than occasional extreme efforts.

Should I follow local mission health and security instructions even if they feel excessive?

Yes. Field instructions are based on current risks, local incidents, access constraints, available medical care, security analysis and organisational duty of care. Follow them exactly unless a designated adviser changes them.

How do I avoid burnout during humanitarian work?

Keep boundaries, take rest seriously, use leave, avoid working every waking hour, talk to your manager early, use peer support and report signs of overload before you collapse.

What should I do after an animal bite or scratch?

Wash the wound immediately with soap and running water for at least 15 minutes if possible, report it, and seek urgent medical advice about rabies post-exposure prophylaxis.

Is malaria prevention just tablets?

No. Malaria prevention depends on the right chemoprophylaxis where recommended, plus bite avoidance, repellent, long clothing, screened rooms, treated nets and quick action if fever develops.

When should I seek medical help on deployment?

Seek help early for fever, persistent diarrhoea, dehydration, breathing difficulty, confusion, injury, animal exposure, sexual exposure risk, mental health deterioration, heat illness or anything that feels unusual and worsening.
