Is it possible that because these diseases had less impact, less people worked on them? It seems like virtually every scientist in even a tangentially related field is working on Cov-2. Not to mention that we have made significant improvements in technology even over the last decade. I am not saying that this proves or disproves your comment, but couldn’t it be said that more people, resources and technology could get us answers faster in 2019? Especially if we are building of research and knowledge we have acquired over the preceding 2 decades?
