I am travelling to Ethiopia and I was informed that you don't need medication regarding Malaria if you go to Addis Ababa. This is due to the fact that the city is above 2000mts where the mosquitos that spread it don't exist.
That was fine with me since I didn't have any plans to leave the capital. Meanwhile I will stay a few days longer and plans started imediately "popping".
I read in this website that you are safe all around the highlands, since these are all in average higher than 2000Mts but is this good enough? how about if you go into a valley like where Blue Nile is (1800mts)?
How far can one go, and which directions, from Addis Ababa without prevention medication for Malaria?
