Virus Spreading Quiz Puzzle

This is a slight re-hashing of an old puzzle, to make it more topical. Do you recognise it? Can you remember the solution? Or can you solve it anyway?

Every person who catches this particular virus becomes infectious one day later, and then remain infectious for two weeks. Every person who has the virus and is infectious will infect one other person every day until they become noninfectious.

In a particular population, one person catches the virus, and then the infection pattern described above goes into action. By the time the original person becomes noninfectious, how many people have the virus, assuming that the population is not yet completely infected?
