(ANSA) - ROME, 02 MAR - The spread of highly contagious coronavirus variants risks fueling the arrival of a "fourth wave of cases" in the United States.
This was stated by the head of the US Center for Disease Control and Prevention (CDC), Rochelle Walensky, as reported by the BBC.
Last week, he stressed, around 70,000 new cases of Covid-19 were recorded per day and nearly 2,000 deaths per day, "a very high number".
"At this level of contagion, with the spread of variations, we risk completely losing the hard-earned land," said Dr. Walensky. "These variations are a very real threat to the population and to our progress." According to American experts, the variant that will become the dominant strain in the United States will be the "English" one. At the moment there are 2,463 cases of the variant registered in the USA according to the data of the CDC, most of these (2,400) are people infected with the mutation that appeared for the first time in the United Kingdom.
