Redpaddy - I know of the "world" renown Tropical Disease Centre in Liverpool and the one where I studied in London There is also a very good Department of Infectious Diseases and Tropical Medicine at the Monsall Unit, North Manchester General Hospital. You say "The Specialists there are all so insistant that there still isn't anything much good at stopping Malaria" Which specialists and who exactly are you talking about?

magykal1 - sound advice!

Blimey Redpaddy, do you work for the Brewer's Yeast Marketing Board or something?

Listen carefully, casual readers... Anyone travelling to a malarious area should get proper advice from an appropriately trained medical professional.

Luckily the Yucatan peninsula is outside the malaria zone (unless you're right down near the border with Belize) so Gixer probably only has to worry about unpleasant itchiness. For up-to-date Malaria maps and other travel heath advice why not look at the quite fantastic NHS Scotland 'Fit for Travel' site:

Here's a little piece of research from the University of California you might be interested in:

Oh and incidentally - Post#23#.... Malaria does exist in Yucatan. It's a small risk - but it's there.
Please don't take my word for it though. Check out....

magykal1 -

1. "Listen carefully, casual readers... Anyone travelling to a malarious area should get proper advice from an appropriately trained medical professional." Excellent advice!

2. "NHS Scotland 'Fit for Travel' site:" user friendly and regularly updated

3. I have taken the liberty of extracting some very appropriate information from your University of California link:-

Repellents. If you find yourself in a situation where you must be exposed to biting mosquitoes, there are several things you can do. First, minimize the exposed skin surface by wearing a hat or head net, long trousers, and a long-sleeved shirt. Some mosquitoes will bite through lightweight clothing, but the number of bites received is definitely reduced if most areas of the body are covered. When mosquito densities become very high, you may want to apply a mosquito repellent. Most effective repellents contain DEET (N,N-diethyl-meta-toluamide). Commercial repellents contain varying concentrations of DEET, usually between 10 and 50%. DEET is an irritant to some people and it may damage synthetic materials such as clothing or plastics. Special formulations for children contain low concentrations of DEET in an oil-based medium that slowly releases the compound and limits its absorption through the skin; these formulations also work well for adults. The insecticide permethrin functions as a repellent when it is applied to clothing; it should not be used directly on the skin. Repellents have their drawbacks: they are effective only for about 4 hours or less depending on wind, high temperature, high humidity, and sweating. When applying DEET, thoroughly apply the material to all exposed skin, including behind the ears.

If you wish to avoid DEET, there are few, if any, effective alternatives. Plant oils such as those from birch, blue stem grass, geranium, pine, rosemary, spearmint, yarrow, lantana, and neem have been shown to be somewhat repellent to mosquitoes, but most are not available in commercial mosquito repellents.

Some body lotions such as Avon Skin-So-Soft offer a degree of protection from mosquito bites at least in part by forming an oily film on the skin's surface that prevents the insect's mouthparts from penetrating. Materials that form protective layers on the skin must be reapplied frequently.

Other Repellents. There is a vast array of other products marketed to repel mosquitoes, most of which are ineffective. These include wrist bands that contain an aromatic repellent, ultrasonic emitters, electric grids, electronic repellers, aromatic plants (the most common one is the so-called mosquito plant, Pelargonium x citrosum), incense coils, vitamins (B1), and mixtures of brewer's yeast and garlic. Researchers have shown that all these methods are of little or no value in repelling mosquitoes. Oil of citronella, which is extracted from Andropogon nardus, has long been claimed to repel mosquitoes. Burning citronella candles or mosquito coils works best if there is relatively little air movement, but these products are only for use outdoors, which makes them mostly worthless. Electric bug zappers that are used to kill pest insects are probably counter productive because many of the insects caught by these traps are those that prey on mosquitoes.

- "Sorry all you sceptics - I'm not a Specialist, but I know a few people (amongst the very best) that are." We are still awaiting the names of the "very best" If they are health care professionals they will not be recommending brewers yeast tablets for sure.

Yes, I didn't say that it didn't, I said that the risk was near the border with Belize, I also provided a link to a site containing a map showing where the malaria risk zone is.

Please don't reply unless you have something further to contribute, just to reply 'Yawn' is unnecessary and insulting. And boring though it may be to you it would be a shame if a TP member were to contract Malaria because of your duff amateur medical advice.

I'm not going to post on this thread again, but am going to sign off by repeating that anyone travelling to any country where there could be any greater risk to their health than usual should consult a professional and not rely on the haphazard advice provided by the likes of us on an Internet travel forum......

Quoting Redpaddy

Very good link Redpaddy - Did you actually read the section on Malaria?


This tropical scourge isn’t common, nevertheless it cannot be ignored the ramifications are just too severe. México has for years conducted intensive mosquito spraying, and dwelling sterilization for malaria. Even the most humble palm frond beach hut is sprayed annually. The chances of encountering a malaria carrying mosquito are slim. But the further you go into the jungle and the later into deep summer you stay, the greater your chances of encountering the particular mosquito species that harbor the disease.

Prevention is overwhelmingly successful. Ask your family doctor for advice about prevention with anti-malarial medicines. Most require that you start taking them one or two weeks before arriving in Yucatán. Mosquito repellents such as Cutter’s‘ with 100% DEET are effective.[i]

Special Note: Don’t let the subject of malaria scare you away from visiting this area! The bare fact is that millions of visitors have visited Yucatán in the last thirty years and only a half-dozen summertime jungle bashers have contracted malaria. This is a summer rainy season issue. I camped on a remote beach near Belize through one summer and my Méxican neighbors reported that malaria was quite rare."

I see that magykal1 has already replied. At no point did magykal1 say that malaria did not exist in Yucatan

Post#26#.... Who are 'We' (quote...."We are still awaiting the names of the very best") ?? I see just a couple of people having a dig at me - not the whole forum. I do wish you'd just calm down a bit - and realise that there are people out there that know more than you.
This is a forum for advice (not continuous arguments - like you are insisting on creating. You are ruining this Post entirely, for everyone) - and I'm giving it, on my experiences. It seems all you wish to do is get very hot under the collar and blow off a lot of unjustified steam - ruining the chat for everyone. Why don't you look at the websites I've recommended you read - or, although they're all specialists - aren't they quite up to your spec?? If you don't stop being so aggressive, I'll report you.

Redpaddy - I would be more than happy for you to report me. Your advice is baseless and irresponsible. Please provide the names of your specialist contacts. You glibly throw in this 'specialist' element as in some way to give credibility to your unscientific and non researched advice. magykal1 - has provided excellent advice and links on this subject!
