Pathogen Puzzle 1

The contact chart above shows who is infected (green dots) and who is not infected (grey dots). The pathogen takes one day to infect all those that come into contact (adjacent, connected dots) with an infected person, unless they are vaccinated against the pathogen.

The pathogen has had 5 days to spread after the initial infection, and 3 people have been vaccinated.

Can you determine who brought the pathogen into the population?
