The messaging from the media (who are laypersons) and the politicians (who are economically motivated laypersons) has been that this is "just the flu". Weak messaging from both the WHO and the CDC has only reinforced this in the public's perception.
The WHO should have taken the decisive move to encourage greater caution by employing the "pandemic" label. That label comes with real power. While there is danger in crying wolf, it was evident months ago from the growth rate of the virus and the lack of quarantine procedures being put in place that this virus would reach the pandemic stage.
If the role of the WHO is to stave off pandemics and not just to monitor them, then elevating the risk profile of the virus should have been a top priority. Since people look to the WHO for guidance, their actions have direct impact to sequestration and bringing the outbreak under control.
Both the WHO and the CDC were too afraid to take early action. Their wait and see approach will ultimately result in more human deaths and suffering.
