Fever after travel assessment (Assessment of fever in the returning traveller)

What is a fever-after-travel assessment?

A fever after travelling abroad is taken seriously because it can be the first sign of malaria, which is a medical emergency. Falciparum malaria can become life-threatening within days, so a fever in anyone who has been in a malaria area in roughly the last year needs to be checked the same day.

The assessment is a careful history (where you went, what you did, when you got back), an examination, and blood tests. The single most important test is a malaria blood film, which is looked at under a microscope, often alongside a rapid malaria test.

Malaria is not the only worry. Fever after travel can also be dengue, typhoid (enteric fever), hepatitis, a tick-borne infection or, rarely, a more dangerous virus. The point of the assessment is to find treatable, time-critical infections fast.

This is not a routine appointment. If you have a fever after travel, you should be seen urgently — through NHS urgent care, A&E or an infectious diseases service — not booked in for a private clinic slot days later.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Options at a glance

These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.

Preparing for your test

• If you have a fever after travel, treat it as urgent. In England, Scotland or Wales you can call NHS 111 for advice on where to be seen; in Northern Ireland, contact your GP out-of-hours service or your HSC Trust's Phone First service. You can also contact your GP urgently or go to A&E — phone ahead if you have been somewhere with a serious infection risk.
• Write down exactly where you travelled, including stopovers and rural areas, and the dates you were away.
• Note what you did: freshwater swimming, animal or insect bites, unwell contacts, food and water, sexual contacts, and any healthcare you had abroad.
• Bring a list of any antimalarial tablets and vaccines you had, and whether you took the tablets exactly as prescribed.
• List all your symptoms and when they started, including rash, diarrhoea, breathing problems, headache or jaundice.
• Bring your medicines list and any results or letters from being unwell abroad.

What happens

You will be asked in detail about your travel and what you did, then examined. You may be asked to wait in a side room, which is a normal precaution to protect other patients while serious infection is ruled out.

Blood is taken for a malaria film and rapid test, a full blood count, liver and kidney tests, inflammatory markers and blood cultures. Further tests are chosen based on your travel and symptoms.

If malaria is found, treatment starts straight away and you are usually admitted. If the first malaria film is negative but malaria is still possible, you may be asked to return for repeat films over the next couple of days, because one negative result is not enough to rule it out.

If you are very unwell, you may be admitted for treatment and monitoring while results come back.

Is this test right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

The biggest danger is not the assessment itself but delay. Malaria, especially falciparum, can deteriorate within hours to days, so the main risk to avoid is treating fever after travel as something that can wait. Always tell the clinician everywhere you went and that you have travelled, even if you feel only mildly unwell.

Published figures to discuss

There are no meaningful complication rates for the assessment itself — it is blood tests and examination. What matters is the underlying risk: malaria can be fatal if missed, and a single negative blood film does not exclude it. Imported malaria still causes deaths in the UK each year, almost always linked to delays in diagnosis or treatment.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is no physical recovery from the assessment itself. What matters afterwards is getting results, starting any treatment, and knowing exactly when to seek help again.

• Feeling tired and washed out while your body fights the infection
• Fever that comes and goes for a day or two while a cause is confirmed
• Waiting on some results for several days
• Being asked to return for repeat malaria films even though you feel a bit better

Aftercare

• Take any prescribed treatment exactly as directed and finish the full course.
• Keep drinking fluids and rest while you recover.
• Use paracetamol for fever and aches if advised, and ask before using anti-inflammatories if dengue is possible.
• Return for repeat malaria films if you have been asked to — do not skip them.
• Watch for the warning signs you were given and seek urgent help if they appear.
• Make sure you know who is chasing any outstanding results and how you will hear.
• Tell any other clinician you see that you have recently travelled.

• Detailed travel itinerary with dates written down
• List of activities and exposures (freshwater, bites, unwell contacts)
• Antimalarial and vaccine record
• Current medicines list
• Note of when symptoms started
• Someone who can stay with you or take you back if you worsen
• Saved number for urgent advice (NHS 111 in England, Scotland or Wales; GP out-of-hours or your HSC Trust's Phone First service in Northern Ireland) and for the assessing service

⚠ Get urgent help if…

• Drowsiness, confusion or difficulty staying awake
• Difficulty breathing or fast breathing
• Not passing much urine, or very dark urine
• Yellow skin or eyes (jaundice)
• A rash that does not fade when pressed, or unexplained bruising or bleeding
• Repeated vomiting so you cannot keep fluids or tablets down
• A fever that keeps climbing or returns after seeming to settle

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A normal set of tests is reassuring and often means a mild, self-limiting infection, but it does not rule out every possibility — some infections take time to show up or need repeat testing. That is why you may be asked to return or be monitored even when the first results look fine.

An abnormal result, such as malaria parasites on a film or a positive culture, gives a clear diagnosis and lets the right treatment start. The clinician will explain what was found, what it means and what happens next.

This assessment answers the question for this episode of illness. If you travel again, or if you become unwell again, you would need to be assessed afresh — a clear result now does not protect you in the future.

Related tests, treatments or support

The assessment is often done alongside treatment of dehydration or fever, and may lead straight into specialist infectious diseases care, hospital admission, or public health notification if a notifiable infection such as typhoid or malaria is confirmed.

Follow-up & long-term care

Follow-up depends on the cause. You may be reviewed in an infectious diseases clinic, asked to return for repeat malaria films, or told your GP will receive the results. You should always leave knowing who is responsible for any tests that are still pending and how you will be contacted.

Repeat, follow-on and what comes next

• Repeat malaria films are routine, not a failure — up to three over about three days may be needed before malaria is ruled out.
• Some travel tests take days, so a normal early result may need to be revisited as further results return.
• If symptoms persist or change, you may need to be reassessed even after an initially normal workup.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

• Clear written safety-netting: specific warning signs and exactly where to return, day or night
• A named route back into urgent care, not just 'see your GP if no better'
• A plan for repeat malaria films and for chasing pending results
• Onward referral to infectious diseases when the cause is serious, unclear or notifiable

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• Whether you are seen through NHS urgent care (the safest, appropriate route) or a private service
• The number and type of blood tests and cultures needed
• Whether imaging such as a chest X-ray or ultrasound is required
• Whether specialist infectious diseases or tropical medicine input is needed
• Whether admission to hospital is required for treatment or monitoring
• Whether repeat malaria films or follow-up appointments are needed

• Confirmation that fever after travel is treated as urgent, not routine
• Which malaria tests are included and how quickly results are available
• What general and travel-specific blood tests are covered
• What happens, and what it costs, if you need admission or specialist transfer
• Who reviews and communicates results, and over what timescale
• What the plan is if the first tests are normal but you are still unwell

On the NHS? This is urgent NHS care. Fever after travel to a malaria area should be assessed the same day, not deferred to a routine private booking. If you are seriously unwell, call 999 or go to A&E. For urgent advice on where to be seen, use NHS 111 in England, Scotland or Wales; in Northern Ireland, contact your GP out-of-hours service or your local HSC Trust's Phone First service.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a specialist safely

• Check the specialist is on the GMC Specialist Register for this area.
• Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
• You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
• Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including any follow-up — before you decide.
