The vision of MERs manifesting outside Middle East indeed has happen - but after postponing 3 years later.

Thus must eradicate the source of MERs - ie. either camels, bats or ???

It the source of MERs is not eradicated like H7N9 - where the source is the chicken or birds, it will stay dormant waiting for mass human infection.

Why this advice is not heeded for 3 years ?????????????
