The most likely infection period for a malaria was before August 15th, while staying in Homabay and at Lake Victoria. On August 25th, I developed a high fever and was advised to approach The Centre of Inner Medicine, Department for Infections, HIV and Tropical Medicine of the Clinic of The Johann-Wolfsgang Goethe Universität in Frankfurt Main (Building 68, 1st floor for reception). The quick test immediately showed a positive result for malaria and the microscopy diagnosed a malaria tropica with a 0.6 % density of Plasmodium falciparum. From there is was only a short way, one floor down, where I spent 5 days in stationary treatment. I am not aware, I had more than three mosquito bites during the potential infection period, as I was extremely careful, using net and extra strong repellent at all time. And all of these three were during daytime (when the anopheles is not active). But I must have missed at least one.
Treatment was with Riamet at 0, 8, 24, 36, 48 and 60 hours. Additionally, because the white blood cells shot up and there was a secondary infection suspected, I received 5 days of IV antibiotics. Malaria of this kind in a very draining experience. But I was surprised, how fast the symptoms faded and also the plasmodium count dropped. Be prepared for hot and cold sweat, fever way above 40 Celsius, attacks of trembling and hallucinations. To make it short: it's like in the movies.
Well, I learned that in high risk regions it is better to take the malaria prophylaxis (even der side effects are strong). As my friend Erick said on the evening arriving in Kisumu: "Here you are just one bite away from a malaria". He was right.
