re bonjour!
J'ai oublié de préciser que le diagnostic du palu se fait avec ce qui est appelé "la goutte épaisse";il suffit d'un simple prélèvement de sang sur le doigt, par exemple, fait par l'infirmière ou le médecin, et envoyé au labo pour analyse, si le résultat est + seulement, alors vous pouvez prendre un traitement!(qui n'est jamais sans effets indésirables, sauf avec les nouveaux).
Ceci pour dire de ne rien prendre, sous prétexte que l'on a des symptomes qui ressembent à ceux du palu!(fièvre, fatigue, maux de tete, de foie )
Autre infos connues mais bonnes à rappeler:le moustique n'aime pas le froid ;donc avec la clim pas de problème, idèm avec l'altitude mais à plus de 2500 M voir 3000 !mètres c'est bon !
enfin un très bon livre que TOUS les grands voyageurs du monde devraient connaitre(entre autres):LE VIDAL DU VOYAGEUR un guide de santé qui traite de lensemble des problèmes spécifiques à chaque pays, chez LAROUSSE DIFFUSION( je n'y ai aucun intérets!).Environ 15euros. JACQUES
bon, on y va: "Le plasmodium, sa vie, son oeuvre".
Ce charmant parasite change de forme tout le temps, se développe chez le moustique, est transmis à l'homme lors de la piqûre, va se développer et se multiplier dans le foie, change à nouveau de forme, sort du foie et va se loger dans les globules rouges, où il mange l'hémoglobine, se multiplie encore, casse les globules rouges, va en infecter d'autres, puis, après quelques cycles comme ça, finit par changer à nouveau de forme et attend tapi dans les globules rouges qu'un nouveau moustique vienne prélever du sang pour l'infecter. Ce cycle prend du temps (des jours, voire plus)
La fièvre, c'est quand un nombre suffisant de globules rouges infectés explosent en même temps sous la pression des parasites qui sont à l'intérieur, donc c'est un moment précis du cycle . A ce moment là, on peut pratiquer un examen sanguin, dit "goutte épaisse", associé à un "frottis sanguin" (je rentre pas dans la technique) qui va permettre de voir les globules rouges qui contiennent le parasite et surtout de les compter, soit en nombre de globules infectés par mm3 de sang, soit en pourcentage de globules infectés par rapport à ceux qui sont sains.
Donc, pour que ces examens soient positifs, il faut que l'on soit en période de développement du parasite dans le sang (s'il est dans le foie, on ne verra rien), donc au moment où il y a de la fièvre...
Il existe d'autres examens dits immunologiques, peu pratiqués de façon courante.
De plus, dans les populations qui vivent en zone impaludée, il se crée une immunité partielle (il faut des années) qui fait que des crises se produisent sans fièvre. Cela détruit les globules rouges, donne des anémies, des augmentation de taille de la rate, des problèmes de retard de croissance importants chez les enfants. C'est un énorme problème de santé publique.
Donc, si l'on pratique des frottis/goutte épaisse chez tout le monde en Afrique, on va trouver des parasites chez beaucoup de gens, sans fièvre. Là, compter les globules infectés est important .
Pour revenir à la question de départ, il est important si vous avez de la fièvre en pays impaludé (ou au retour+++) de faire rapidement pratiquer ce frottis/goutte épaisse (ça peut se faire même dans les dispensaires ou les petits hôpitaux de secteur). La prise d'un traitement curatif de votre propre initiative ne se conçoit que si vous êtes vraiment loin de toute structure médicale, et il faut vous diriger tout de suite vers une ville équipée. J'insiste. Le risque étant bien évidemment de laisser évoluer une autre maladie qu'un palu.
Personnellement, j'ai fait il ya quelques années un superbe accès de fièvre en retour de voyage, tout à fait évocateur de palu. C'était un abcès amibien du foie...
bonjour toukoul!
avant tout merci pour la REGAB bien fraiche!
A part cela tu as eu combien de crises de palu pour douter du test de la goutte épaisse? .je parle de crises causées par le plasmodium falciparum, les autres parasites:P vivax, P ovale, P malariae étant reconnus comme moins dangereux ?. c'est tout ! jacques
Très joli ton symbole mobile.Enfin, pour te dire que l'on peut, avec un peu d'écoute, de tolérance, arriver à communiquer ;la preuve!,
Dans les années 78 J'avais acheté :"le droit à la paresse" de paul lafargue ;une révélation, un témoignage, très fort, de ce que je pensais depuis longtemps, tode plus, écrit, si ma mémoire est bonne, en, 1848!!
Désolé pour les lecteurs, qui ne vont rien comprendre à ces propos hors sujet, mais, je sais que, toi, tu as tout compris! don't you??
Amicalement, jacques.

Pour revenir aux crises de Palu.
J'ai fait un 1ère crise à 6 ou 7 ans.
Mon père en temps que vieux broussard et parti du principe qu'il n'y avait rien à faire sinon répondre de façon symptomatique et prévoir des draps et des pyjamas.
De plus en Asie du Sud-Est à cette époque, on s'en tapait un peu beaucoup des examens sanguins.
Hi there,
Do you know of any good travel insurance? Usually, I go with the one from the agency. But this time, I want to travel independently, and I'm a bit lost.
Some people told me that when you pay with a credit card, you get the bank's insurance. But after checking with the bank, that's not true. Or else, you have to add an extra option and pay for it monthly.
So, I'm looking for insurance that covers cancellation, repatriation, lost luggage, etc.
Thanks for your tips!
Hi there,
A friend has osteoarthritis in the knee and a meniscus problem, treated with regular injections.
Do you know of any insurance companies that cover pre-existing conditions in case their knee locks up in Africa?
Thanks a bunch!
A one-month trip to Australia and New Zealand.
We’re bringing our current medications (for blood pressure, cholesterol, diabetes, and antibiotics if needed) along with the corresponding prescription.
Do we need to have it translated into English, or do translations only apply to medications we’d need to refill locally during a long stay?
Hi,
I’m planning a trip to Namibia for 3 weeks in November: should I take malaria prophylaxis, which medication, when to take it, and are there any side effects?
At the end of my trip, I’ll spend 5 days up north near the Angolan border and in Etosha National Park.
Thanks for sharing your travel tips and advice!

I’m planning a trip to Japan next year and I have asthma...
I wanted to know about the regulations regarding Ventolin (Salbutamol) in Japan—is it considered a drug? Can I bring my inhaler with me, or do I need to buy a similar product in Japan?
I have two American cousins. The older one was born in Paris, and his sister was born in California. The latter is planning a trip to Paris this summer, but she recently fell ill, and American doctors don’t know what’s wrong. I had the idea of letting her take advantage of her trip to get treated here, avoiding the high healthcare costs of the American system in the process. The problem is, I can’t find anything online about this—just testimonials from French people who used to be American, but nothing for a simple tourist.
I’m traveling to Portugal with my family and I have a treatment that requires injections. How can I take a flight with these? They look like injectable pens.
Thanks
We’re planning a trip to the Philippines from April 22 to May 8, 2026. Flight from Geneva with a layover in Turkey and Manila. Our itinerary: Angeles – Busuanga – Palawan…
The Philippines are a dream destination, but is it possible to travel there safely? I’ve heard that checked luggage often gets lost, tap water isn’t safe to drink, and mosquitoes are everywhere.
For water, what’s the best solution to carry in a backpack? Is a filtering water bottle 100% reliable?
For mosquitoes, should we treat our clothes with repellent? Are you vaccinated against hepatitis A, malaria, or dengue? Or is there an oral treatment to take?
Hi there,
Does anyone know if there’s travel insurance for someone who’s had a heart attack?
I can’t find an insurer that covers a pre-existing condition, even if it’s stable.
Thanks so much!
Hi everyone, next month my wife, our 6-year-old daughter, and I are flying to Thailand. It’ll be a great chance to soak up some sun—something we’ve been missing lately here in France! But speaking of sun, I burn easily, and our daughter even more so. I was wondering what SPF to get for sunscreen and whether it’s better to buy it there or before we leave? Thanks for your tips!
Hello,
We’re planning to spend 3 months in Madagascar starting in mid-February.
Areas: Mahajanga, Tulear, Diego Suarez, and Sainte Marie—the order isn’t set yet. We’ll either drive for part of the trip or take flights.
We’ve heard all sorts of things about required vaccines and medications (is anti-malarial mandatory?). What’s the exact situation for travelers?
I’ll come back to you for other topics (like finding a reliable driver, among others).
Thank you.
Best wishes to you all,
Nicole
We're about to go on an organized trip to South Africa, including Kruger Park. We were told that Malarone should preferably be taken in the evening at the same time during a meal. But it's hard to know what time we'll have dinner, especially since I've read that in South Africa, dinner is usually around 6 PM.
I'd love to hear from people who've been on organized trips to this destination and could share their experience. We were thinking of taking Malarone around 7:30 PM, assuming dinner would be closer to 7 PM than 6 PM. Also, if the meal ends up being earlier or later than when we take the pill, would a cookie or a piece of bread be enough to take with Malarone?
I’m planning to set off on a "round-the-world" trip/long journey at the start of next year, lasting between 4.5 and 6 months. For now, the itinerary looks like this: South Korea (2 weeks) -> Japan (1 month) -> New Zealand (1 month) -> Argentina (1 month) -> United States (1 month).
I’m on medication (paroxetine 20 mg/day) and was hoping to bring enough for the entire trip so I wouldn’t have to find a doctor on the spot, deal with a molecule that might be slightly different from what’s available in France, or wonder if that’s even a possibility. Basically, it seemed simpler on paper...
But after looking into the regulations for each country, it’s suddenly way less simple . Many seem to only allow the amount corresponding to the length of your "stay" in the country... Which is a problem if I arrive in Korea with 4.5 months’ worth of medication, for example.
After all that, and even though I’ll obviously contact the relevant authorities in each country (fingers crossed for a response 😛), here’s my question:
Has anyone here had any experience with this? (Even if it’s a different medication or different countries, any input would be helpful!)
I’m trying to plan a trip to Dubai with my mom. I’ve seen that some of our medications require prior authorization (sleeping pills, codeine, anti-anxiety meds, etc.).
I’d love to hear from anyone who’s been in our situation. A friend of mine applied to bring her tramadol, but it was denied—though she needed high doses!
Has anyone here gone through this process? Do we *really* need a prescription in English?
We just found out my wife is pregnant, and we’ve planned a trip to the Barlavento Islands in Cape Verde this November.
We’d like to know if there’s a real risk of Zika contamination on those islands, because from what we’ve found online, the recorded cases are old and come from the Sotavento Islands.
We’re thinking about canceling our trip.
If you’ve recently traveled to Cape Verde or live there, do you have any thoughts on this?
hi, I’m looking for information about the possibility of returning to Thailand with a portable liquid oxygen system and whether it’s possible to recharge it in Thailand, especially in Chiang Mai. thanks
I’m starting a new discussion on this topic since there doesn’t seem to be a recent one.
I have several chronic conditions (including asthma and related ones), and I’m planning to travel for a year across different countries.
Generally, I understand it’s possible to travel with approved medications (which should be my case), but often with a limit of 3 months’ worth of treatment.
Since I’m going for 12 months, that means for three-quarters of my trip, I’d have more than 3 months’ worth of medication.
I plan to bring my prescriptions with the INN (International Nonproprietary Name), as well as the original packaging (even though it’s a nightmare, but from what I understand, it’s necessary). But I’m not sure if that’s enough...
Have any of you been in this situation before? How does it work at customs—do I need to declare everything that exceeds the 3-month limit? Do I need a letter from my doctors?
I'm currently in Bangkok: How can I find a good doctor for a consultation? It's for a friend who'd like a second medical opinion compared to what they got in their country of residence.
Any professionals you'd recommend? How much does it cost?
I’ve already visited quite a few countries across several continents, but I’m pretty new to Asia.
I’m planning a trip to Thailand in October or November, and I wanted to check about health precautions: malaria treatment, vaccinations (hepatitis A or others...).
I’ll mostly be in the northern region, around Chiang Mai, where I’ll spend a lot of time in nature and the mountains. Then I’ll head south to Phuket or Krabi and visit Khao Sok National Park. I’ll finish up in Bangkok, with a likely detour to Kanchanaburi.
From what I understand, for a stay of less than 60 days, I don’t need a visa (I’m a French national)? I just need to fill out the TDAC form 3 to 5 days before arrival?
Hi there,
I was wondering if anyone is heading to Cuba soon and could bring me some over-the-counter Sildenafil (viagra) tablets—available at Varadero Airport, among other places.
Hi there! So, I'm hesitating about taking a long trip. I'd like to go away for 2 to 3 months and travel across several continents. I’d love some advice. I often have unexplained allergies and need to follow a daily treatment for my diabetes (insulin). I think I can get authorization from my doctor to travel for 6 months with the treatment—is that correct? After those 6 months, is it possible (instead of bothering a relative to send the medication) to see a foreign doctor to get another 6-month travel authorization? How does it work at the airport? Do I need just one medication transport authorization, or do I have to request a new one in each country (once the treatment runs out) for both the flight and a DCI? Also, travel insurance doesn’t cover chronic illnesses, so will I have to pay for foreign consultations out of pocket? I’m not sure if I explained myself clearly. Oh, and just to repeat—travel insurance doesn’t cover chronic illnesses, so foreign consultations will be at my own expense? Thanks in advance for your help!
Hi everyone.
After years of traveling to the USA without any medical insurance subscriptions—and luckily never having any major health issues (though I did get a scorpion sting buried in the sand at CBSouth, 😇)—life has caught up with us, and we’re now being forced into "wisdom" and leaving our carefree days behind.
So, I’m looking for the best compromise for a 2-month health insurance plan.
I’ve read the discussions on this topic, but the most recent one is from last year, and I’d love your take on the current situation.
I’m familiar with the usual options like Europ Assistance and AXA, but I’ve just discovered Chapka and Heymondo (the latter seems interesting in terms of both price and coverage).
What do you think of these last two? How do they compare in terms of value for money against the bigger companies?
Hi,
We’ve planned a 3-week trip to Bali this summer with our 7-year-old daughter. The itinerary includes Sanur, Nusa Lembongan, Sidemen, Amed, and Ubud. The more time passes, the more we read about people getting sick—some with mild to severe traveler’s diarrhea, and many ending up in the hospital. We, as parents, have been through it in Egypt with pretty bad cases, but we’d really like to avoid that for our daughter. Even though there’s no zero risk, and we’ll be careful, can any of you reassure me? Not everyone got sick, right? I’d love to hear positive feedback from parents, but not just them 😊. Thanks in advance!
Hi there...
I’m traveling with a friend for a month in November.
We booked our round-trip tickets from Paris to Phnom Penh, and yes, I know—it was a mistake. We should’ve flown out of Laos, but here we are.
But is it doable to backpack through both countries in a relaxed way?
I’ve seen that the transport takes a while...
Thanks so much for your replies.
Hi there,
I’ve started looking into getting dental implants, possibly in Costa Rica or Mexico.
Do you have any clinics to recommend or ones I should avoid?
For the next steps, I need to choose between Cuba Medika or Medigo—these are agencies that help with medical procedures. Do you have any info on either of them?
Hi everyone, a question for those who’ve been lucky enough to visit Raja Ampat—should you consider preventive malaria treatment given its proximity to Papua? And how was the food hygiene situation?
Thanks for your feedback! !
For several years now, increased aggression has been observed in Cape fur seals.
At least 70 unprovoked attacks on humans.
It was recently confirmed that this is due to rabies.
The suspected origin is contamination in Namibia by jackals.
The contagion seems to be spreading.
Preventive vaccination (of the animals) is being considered.
Just a reminder:
Rabies affects all mammals.
Once symptoms appear—sometimes weeks or even months later—death is inevitable.
It’s the bite that transmits the disease.
There are so-called "furious" forms with aggression, but also forms without aggression.
In case of a bite, in addition to standard wound care, tetanus prevention… rabies prevention is essential.
Stay careful out there…
Seeing seals from a boat along the coast isn’t rare in these parts…
