How do they compare? The End of the World vs The Virus

Hey :)

I wonder if anyone has seen both or one of the two titles:  The End of the World (2013) & The Virus (2013)

While watching The End of the World I realized a few episodes in that I actually wanted to watch The Virus. Because they sound so similar and have similar pictures  in my head their where one drama only. So know I would like to know how each of them are.

I feel so confused after I figured out my mistake.
