The WHO is in a bit of a pickle. In February this year it declared the Zika virus a Public Health Emergency of International Concern (PHEIC).
A PHEIC is defined as a situation likely:
i. to constitute a public health risk to other States through the international spread of disease; and
ii. to potentially require a coordinated international response”. This definition implies a situation that: is serious, unusual or unexpected; carries implications for public health beyond the affected State’s national border; and may require immediate international action.
Today an open letter signed by 152 Health Professionals from all over the world has been sent to the UN asking for the games to be postponed or cancelled.
In response the UN has said that the games should go ahead (partly) because a lot of time, effort and money had been spent by the IOC and athletes to make the games a success.
Well, excuse me. Either the Zika virus is a PHEIC or it is not. It cannot be both simultaneously any more than a woman can be a bit pregnant.
