In my own point of view, this is a kind of trend this year or maybe 'til next year. But there are much more deadly deseases that existing ever since,  which are also exist anywhere. Such as HIV/ AIDS,Malaria, Dengue fever and many to mention. Did we care about these? No, not unless we are already have it.

Who are to blamed? Of course us, for being careless in ourselves and in our environment. Honestly, we are amusing and enjoying our life with modern technologies. We ignore our natures which protected us in natural calamities.
