I want to start off by addressing the structure of the article, so far it is very clean and precise. The attention to detail within the contents is especially pleasant. This definitely works as a good skeleton for the rest of the article. Reading the article and seeing the structure gave me some applicable solutions for my own, in terms of the depth of research I include in my own.
I checked a couple of the sources and they appear to be thorough, credible and seem to dive deep in the healthcare topics you decided to implement in the article.
I think some good additions to your article could be adding some background information about Botswana's healthcare system and some information about how Botswana attain its current healthcare system.
Reading the article so far, I feel the biggest improvement to make would be creating more of an introduction to the article. Perhaps you can include more information about the healthcare system as a whole and possibly mention key milestones Botswana's healthcare system has achieved that you are able to elaborate on later in the article.
So far the article shows many strengths within the neutrality and balance of the content.
