super-spreaderNew Word Suggestion
What is a super-spreader? It is a bit of a vague term, with no strict scientific definition. But it is when a patient infects significantly more people than usual. On average, each person infected with the new coronavirus is passing it on to between two and three other people. But this is only an average; some people will pass it on to nobody while others pass their infection on to far more. [BBC, Feb 2020]
