The US is at risk of losing all its recent gains in the battle against Covid-19 as highly contagious variants take advantage of Americans getting lax with safety measures.
"Please hear me clearly: At this level of cases with variants spreading, we stand to completely lose the hard-earned ground we have gained," said Dr. Rochelle Walensky, director of the US Centers for Disease Control and Prevention.
After weeks of tumbling case numbers,
new infections are on the rise again -- about 2% more this past week compared to the previous week, Walensky said Monday.
"Similarly, the most recent seven-day average of deaths has also increased more than 2% ... to nearly 2,000 deaths per day."

March will be a very important chapter in this pandemic.
The CDC has predicted the highly contagious B.1.1.7 variant first detected in the UK will become the dominant strain in the US this month.
More than 2,460 infections involving variant strains have been reported, according the CDC data. The vast majority of those cases -- at least 2,400 -- are of the highly contagious B.1.1.7 strain.
Those counts are probably much lower than the actual number of people infected by variants. The numbers represent only those variant cases found through genomic sequencing, the CDC has said.
The US has lagged behind dozens of other countries in the proportion of cases tested for variants, but the CDC said it's working to scale up those efforts.
