You know Merse ?? Merse made korean feel fear last year. =MERS made many Koreans frightened last year. we could not go feeling free outside. = We could not feel free to go outside. Apparently you could not imagine how we spent the time during that time. I heard that there is a vaccine to remove Merse . Nevertheless, Why does it last long to get rid of that . This topic is difficult to talk and write in english even korea. Who spreads this virus ?? where does it come from ?? I am totally not sure if when it keeps cleaning , it is okay. Just make sure the more we clean, the less the harmful virus would disappear.   = The more we satinize, the less harmful the virus would be.
