Certainly here in the UK, and I suspect the USA, Ebola went out of the news late last year. Although the West African outbreak was the worst on record, it is sad that it soon became not newsworthy. It looks like the outbreak is now under control but it is a sad indictment of our society that when things go "off the radar" we hear little about them. It is a warning that what is considered "news" is filtered.
