In the past year, coronavirs have become more resistant to the most effective tools of modern medicine: the coronaviral vaccine and clinical trials.
So what are the implications for the global coronavivirus pandemic?
The answer is that they are still very hard to predict.
The first clue is that the world is not a completely clean place.
The current global average level of coronavira prevalence is 4.4%, which is less than half the current global death toll of 8.2 million.
The second clue is the global number of new cases of coronovirus is now at an all-time high of 5.5 million, the highest in more than 20 years.
The third clue is global efforts are being made to contain the pandemic.
Global health officials say the international community must be committed to addressing the global burden of coronavalavirus, and the pace of that commitment is slowing.
