Infectious diseases that were once considered under control are making a comeback.

The World Health Organization (WHO) is raising the alarm about a sharp rise in measles cases across the world, particularly in developed countries such as the United States.

The WHO lists vaccine scepticism as one of the 10 biggest threats to public health.

So why is the disease spreading again?
