According to the question asked by Hendrik Poinar, an associate professor and director of the McMaster Ancient DNA Centre and an investigator in DeGroote Institute for infectious Disease Research, “The research is both fascinating and perplexing, it generates new questions which need to be explored, for example why did this pandemic, which killed somewhere between 50 and 100 million people die out? It is hoped by the scientists that it may lead to a good understanding about the modern infectious ailments which has plague in it that has still the capability to kill thousands of people in between 30 and 50 millions in a year.
