Hello, I am new to the site and I saw that you were looking for an online school in Public Health. I don't know if I am late or what but TUI University has a great one. I am currently in the MSHS in Public Health right now and I think it is wonderful (except for epidemiology). At TUI University I do work full time and do 12-14 hour work days when I do work and still manage to complete class work. It is solely online, which for me is great. I hope this helps some.
