Mr Khan is a hero of our times. Mr Khan died of ebola. He was in charge of the fight to contain this awful disease.
There is a category of people who died from ebola; with currently three entries it is mercifully empty. Then again, that man who died at Lagos airport is not in there.. Probably more people who became notable because of ebola are missing as well.
It is important to recognise ebola for the threat it represents. One of the things you cannot do is run away from it. The only thing that is achieved is spreading the disease even further.
