No idea. I wasn't planning to participate after seeing their persistence, with more than a few voicemails (I generally don't answer to number I don't recognize unless I'm expecting calls.) -- so I called the number back, which basically told me to leave my number and message, so I recorded the message with number to not call again.
Then, they've called me, which I told them to not call me again. (Which they've acknowledged.) Then a few days after they called me again, and I told them the same thing and she got extremely personal, telling me she's just doing her job; justifying reason they can call me despite my earlier denial because she (the attendant) was not the person who made the call earlier.
Complained to CDC via phone (which took me to the voicemail) and via their website, but I haven't received any response. I just had to conclude people involved in those surveys are highly unprofessional and incompetent, let alone not trustworthy enough for giving answer to any health related questions.
