This board is overwhelming...
Anyone know what the malaria situation is like at the moment (March 2015)? Has there been much rain about?
Mainly interested in South of Skukuza.

The recommendations for Kruger between, and including, September and May still remain as they always have: antimalarial drugs are recommended, as well as the ubiquitous non-drug measures (anti-mosquito sprays, mosquito netting, coils, staying indoors between dusk and dawn, etc.) Some people weigh up malaria risk versus the (potential) side-effects of the drugs and choose not to use antimalarial drugs (only non-drug measures), but these decisions remain the responsibility of the decision-maker as the official recommendations still point to antimalarial drugs. The best recommendation then, s2000ap, is to consult a suitable healthcare professional and take it from there, especially as some people are unable to safely use antimalarial drugs and others are suggested not to enter a malarial area at all.

Nor does citronella, I have had mozzies sit on my arm just after I put citronella cream on me. For me Citronella is so overrated.

Just take malaria prophylaxis. Prevention is better than cure, just don't use Mefliam, it poisoned me in 2012, bad batch. :evil:


Many people will disagree with you, Lepardfan. I, for one, have no problems using Mefliam and, indeed, find citronella-oil products useful. Everyone is different and each must find what works best for him or her. Some people need to use several types of non-drug measures simultaneously, while others will be content with just one or two. Personally, I always tell people to use as many as they comfortably can to ensure that not a single mosquito bites them - after all, it only takes one infected mosquito to potentially infect a person.

Out of interest, which months are the highest risk, within the September to May period?
Kruger National Park, August 2016:

1 night Shimuwini
3 nights Punda Maria
2 nights Mopani
3 nights Talamati
1 night Crocodile Bridge

Where would you say does the high risk area start, i.e. the "malaria border"? One usually hears the north is the higher risk area, but where would you say does the risk increase significantly?

I presume your post refers to Kruger, Eddie? Simply put, there will be pockets of higher-risk areas, such as stagnant pools of water, but as this is not fixed and, in any case, the mosquitoes in a malarially-designated area are pretty much everywhere, the authorities declare the malaria borders according to general averaged frequency of contracting the disease. I've heard people try and justify certain areas as less risky than others, sometimes to lessen the use of antimalarial measures, but the safest and wisest attitude to adopt is that the whole of Kruger is a malarial area whose malaria risk changes seasonally. Keep to the guidelines and malaria-area maps by trusted authorities and you will not go wrong.

Just a hypothetical question:
If one has been in a high risk malaria area and think you have been bitten by a mosquito......can one do a blood test to check before the 14-21 day incubation period? i.e. before any symptoms?

Pjw, I can only give general pointers here as the subject is quite complicated and needs an in-depth understanding to ensure accurate results and interpretation thereof. For example, the type of test and its quality in manufacture plays a role. Then there is the question of the balance between sensitivity of a test and its specificity, with an increase in one factor often meaning a loss of accuracy in the other. Also, no test is one-hundred percent effective in diagnosing every case of malaria. The WHO has guidelines in this regard as to what is acceptable for a test.
In general, the tests pick up antigens to the presence of malaria parasites. There must be a minimum level of concentration of parasites in the blood for the test to find the person positive for malaria infection. So, you must have been infected by a malaria parasite for the test to pick it up, and parasite concentration increases over time. But, yes, it is possible to detect the antigens before symptoms show, especially as some people take an extended period to show suitably noticeable symptoms. The other problem with malaria symptoms is that it may be similar to other diseases, especially colds and flus. Then there is a major problem with malaria testing as well - the lack of sensitivity of a test can lead to false-negatives, which means that the test shows you to be free of malaria, but in actual fact you are infected. On the other hand, the lack of specificity of a test can lead to false-positives, which means that the test shows you to have the disease when you do not.
So, does this mean you should test every time you think you were bitten by a malaria-infected mosquito? I cannot give a definite answer on this, but I think common sense should prevail. If in any doubt, rather have a proper lab-controlled test as this is the gold standard for confirming malaria infection. One cannot rely only on home tests or symptoms, but these certainly are valuable in prompting the individual to seek accurate malaria diagnosis and, if needed, treatment. The goal, after all, for using home malaria tests is early detection of malaria to ultimately save lives. I hope that gives some idea?

Thank you missings. :thumbs_up: What was most interesting is that a bed net lowers risk of contracting malaria more than the vaccine will, and I know that large numbers of bed nets do get issued in some countries. However, what is exciting is that they will probably be able to use this prototype malaria vaccine as a springboard for more sophisticated, and hopefully more effective, vaccines in the future. In any case, if they could lower the risk of fatal malaria by a third with the four-shot course, that, combined with a bed net, should make a huge difference to the malaria death toll in especially children under 5 years of age. :pray:

Thank you for your response, OWN. Its all hands to the wheel, as it were. Spraying, bed nets, a vaccine. Reports say that African countries that suffer greatly from malaria, are held back in their economic development, as even those that recover are always under-pa and never reach their potential.

Yes, Missings, the malaria death toll in some African countries is horrific, the worst affected grouping being under five years of age. Economy is therefore undoubtedly affected. However, if all people in these countries could only receive a bed net (some countries do well, while others are way behind), the reduction in malaria infections is significant.
