If you had it and got over it lead a life with healthy habits, fitness and nutrition so if you do get another bout of it your body will be prepared to fight the next round.
From the reports I'm reading from S Korea in particular there is a chance that the original tests were flawed as could be the current ones. They could've been infected with different flus.
If not this virus is mimicking something like the chicken pox virus which can come back as the shingle after hibernating in the body/nerves I think. They also say stress can lead to something like the herpes virus which is why it can come and go. Sidenote but stress in general affects the immune system and have to wonder what the hyper coverage and attitude toward this affected those who got the virus/sick.
