World Health Organization officials said Wednesday that scientists are trying to understand why Covid-19 cases are suddenly ticking up across much of the world after weeks of falling infections.
There were 2.6 million new cases reported across the world last week, up 7% from the prior week, the WHO said in its weekly epidemiological update that reflects data received as of Sunday morning.
The reversal could be caused by the emergence of several new, more contagious variants of the coronavirus, relaxing public measures and so-called pandemic fatigue, in which people become tired of following precautions, the WHO said in its weekly report.
Ryan reiterated that the cause of the uptick in cases remains unclear, but added that the tried-and-true public health measures that have been emphasized throughout the pandemic are still effective.
"At this level of cases, with variants spreading, we stand to completely lose the hard-earned ground we have gained," Walensky said Monday?
"Please hear me clearly: At this level of cases with variants spreading, we stand to completely lose the hard-earned ground we have gained," she said
