This is one of the best (medical) thrillers I have seen and also a very realistic portrayal of the characters from the actual virus outbreak scenario based on my reading of news reports ( I had closely followed the outbreak when it happened). The makers of this movie has done a great research before creating this movie and a respect them for that.
I thoroughly enjoyed watching the movie and I will recommend this to anyone who wants to watch a good medical thriller.
(One thing I felt that could have been avoided were somewhat gross scenes like vomiting. But then, maybe in a medical thriller - such things are to be expected. )
