At present there is no official warnings to avoid travel to Zambia. While the disease you mention is concerning, it has affected an insignificant number of people compared to the total number of visitors to and from Zambia. At present, my answer is that, yes, it is safe to travel to Zambia. However, I suggest keeping an eye on developments and heeding any official warnings such as those provided by the British Foreign Office:

BloggerZ - the disease warning was posted in October last year when there was an outbreak of a lethal disease. Since then, everything is fine and there is no reason not to go to Zambia.

People are always more paranoid when they travel because they are away from their support structures... giving people information is different to telling them not to go.

Its great that you are patriotic about Zambia tho - no question that it's an awesome country to visit.
