In the last couple of days, WHO officials have criticised the UK government's approach to the COVID-19 pandemic, describing the government's reliance on developing herd-immunity amongst the British population, and apparent reluctance to put in place quarantines as "ridiculous".
China has also been criticised for its initial response to the virus, which the Financial Times describes as a "cover-up", and which US national security advisor Robert O'Brien says "cost the world community two months" in terms of preparation for the disease. This would appear to be in breach of the International Health Regulations (2005), Article 6 of which states that:
Each State Party shall notify WHO, by the most efficient means of communication available, by way of the National IHR Focal Point, and within 24 hours of assessment of public health information, of all events which may constitute a public health emergency of international concern within its territory
Given the criticisms above, does the World Health Organization have any powers to either enforce health recommendations such as quarantines or lockdowns, powers to punish or sanction countries that refuse to comply with said health recommendations, or powers to punish countries that breach their obligations under the IHR?
I have been able to find this article which describes a panel which investigated this in the wake of the ebola crisis, but I can't find more information about the results of this investigation.
