Unwell After Travel: Which Symptoms Need Urgent Help
Medically reviewed by Muhammad Adnan, Superintendent Pharmacist (GPhC reg. 2073652) · Reviewed 2026-05-31

Most trips end with nothing worse than jet lag, but a short list of symptoms is worth acting on once you are home: fever, diarrhoea still going after two weeks, an unexplained rash, yellow eyes or skin, and a cough that will not shift. One of those, a fever after a malaria area, needs same-day attention rather than a wait-and-see weekend.
Which post-travel symptoms need same-day attention?
TravelHealthPro puts a specific group of symptoms in the urgent bracket for anyone recently back from abroad:
- A high temperature or flu-like illness
- Diarrhoea with blood in it
- Severe pain in your abdomen
- Yellowing of your skin or the whites of your eyes
- An unexplained rash
- Confusion or unusual drowsiness
Timing helps too. What starts in the first few days home is often food or water related and usually settles, while weeks two to four bring the slower infections. A fever three months on still counts.
Why does a fever after a malaria area count as an emergency?
Because until a blood test says otherwise, fever after a malaria-risk area is malaria. TravelHealthPro advises immediate medical attention that day for any fever or flu-like illness following time in a country with malaria, at any point up to a year after you return, and is explicit that malaria should be suspected whether or not you took preventive tablets.
So say the word. Tell the clinician where you have been and ask for a malaria test with a same-day result, and do not be reassured by a finished course, since no antimalarial is completely protective. Our malaria prevention page covers how tablets and bite avoidance work as a pair.
NHS guidance puts the usual incubation at 7 to 18 days after an infected bite, notes that symptoms can begin months later, and advises an urgent GP appointment or NHS 111 for anyone with symptoms who visited a malaria country in the previous 12 months. It is blunt about why: malaria is an emergency, and people die from it when treatment comes late.
What if diarrhoea is still going two weeks after I got home?
By then it is no longer ordinary travellers' diarrhoea and needs a stool sample rather than another box of tablets. NHS advice is to see a GP once diarrhoea has run past seven days. Beyond a fortnight a parasitic cause such as giardia climbs the list, with the foul-smelling diarrhoea, bloating and eggy burps the NHS describes. Make it same-day if there is blood or mucus in your stools, a fever with it, or you cannot keep fluids down. Our travellers' diarrhoea guide covers what is reasonable to treat yourself.
What do a rash, jaundice or a lingering cough suggest?
Three different stories, all easy to shrug off.
- A new rash. Most are heat rash or bites, but a rash with a fever after tropical travel sits on the urgent list. Have it looked at the same day.
- Yellow eyes or skin, with dark urine. The NHS lists these among the signs of hepatitis A and advises seeing a GP if they follow travel to a country where it is common. Jaundice is never one to monitor at home.
- A cough that lasts. The NHS threshold for a GP appointment is a cough of more than three weeks. After a long stay in a country where tuberculosis is common, that cough with night sweats, weight loss or evening fevers is worth naming TB out loud. Coughing up blood is urgent.
Which holiday activities need follow-up even if I feel fine?
Some exposures need a plan whatever your symptoms are doing, because these infections are often silent at first.
- Freshwater swimming, paddling or rafting. In sub-Saharan Africa and other risk areas, freshwater contact can mean schistosomiasis, and most travellers who pick it up feel well. TravelHealthPro notes schistosomiasis in travellers is usually symptom-free, and that the antibodies a blood test looks for take eight to 12 weeks to appear, so screening is arranged some weeks after your last freshwater contact rather than the week you land. Our schistosomiasis page explains who should ask their GP to arrange it.
- Any bite, scratch or lick from an animal. Dogs, cats, monkeys and bats all count. Wash the wound with soap and water and get medical help where you are, because the NHS is unambiguous that you should not wait until you are back in the UK. If you started treatment abroad, contact your GP on your return about further doses; our rabies post-exposure page explains that pathway.
- Sex without a condom. Many sexually transmitted infections cause no symptoms, so testing is the only way to know. NHS sexual health services are free, confidential and open to self-referral; NHS advice is to test around seven weeks after exposure if you have no symptoms, sooner if you do.
What should I tell the clinician, and where do I go in Manchester?
The history does most of the diagnostic work, so bring the detail:
- Dates you left and came back, and every country and region, stopovers included
- What you did: freshwater, animal contact, caves, farms, unboiled water, street food, sex, tattoos, or treatment abroad
- Which antimalarial you took, any doses missed, and whether you finished the course at home
- Vaccines you had before departure, and whether anyone else in your group is unwell
Seriously unwell (confused, drowsy, breathless, unable to keep fluids down) means A&E, or 999 if you would normally call an ambulance. For a fever or anything on the urgent list, ask for a same-day GP appointment, or use NHS 111 if you cannot get one, leading with your travel history. A cough past three weeks or screening after freshwater suits a routine appointment. Greater Manchester GPs and hospitals refer on to the regional infectious diseases service when an imported infection is suspected.
What can our Timperley pharmacy realistically do?
We should be straight about this: we are a GPhC-registered pharmacy and a registered Yellow Fever Vaccination Centre on Stockport Road in Timperley, two Metrolink stops from Altrincham, and not a diagnostic service. A fever after a malaria-risk country belongs with your GP, NHS 111 or A&E the same day.
We can still help: talking through what you were exposed to, telling you which door to knock on, completing a travel vaccine course you began abroad such as a hepatitis B schedule, and reviewing your record before the next trip. Post-exposure rabies doses are the exception — those are arranged through your GP or NHS 111, not here. Walk-ins are welcome, Monday to Saturday 9am to 9pm and Sunday 9am to 6pm, and our travel clinic page sets out what a consultation covers.
Frequently asked questions
How long should I keep mentioning my trip to doctors?
At least a year. NHS advice ties urgent malaria assessment to travel in the previous 12 months, and tuberculosis can surface later still. Lead with where you have been rather than waiting to be asked for it.
I feel completely well. Should I book a check anyway?
After a fortnight in a resort, almost certainly not. It earns its place after freshwater contact, an animal bite, sex without a condom, or months in a rural area. Those reasons are about exposure, not symptoms.
My child has a fever a week after we got back. Same rules?
Same rules, with less patience. Children can deteriorate faster than adults, so a malaria area means a same-day assessment and test. Mention the travel when you book, not when you arrive.
Should I bring up last trip's illness at my next travel appointment?
Please do. An unfinished course, a reaction, or a bout of something never identified all change what we would suggest. Travellers from Altrincham, Sale and across Trafford often arrive with exactly that history.
Home in Trafford with a symptom you cannot place, or unsure what an exposure means? We are glad to talk it through and point you to the right service. Book a consultation or call 0161 948 5066.
