<Anchor> In the



United States, the number of corona infections is showing an increasing trend again, and even warnings about the 4th pandemic are coming out.

In particular, it is known that the infection is spreading significantly among students and young people in their 40s or younger who have not yet been vaccinated.



This is Kim Yoon-soo, a correspondent from Washington.



<Reporter> In



Minnesota, USA, more than 740 schools have recently been infected with a mutant virus from the UK.



Corona 19 outbreaks have also occurred in schools in Michigan and Massachusetts.



Normalized schools are becoming the center of infection.



[Gottlip/Former FDA Director of the United States: We are seeing the spread of infection in young people and school-aged children who have not been vaccinated nationwide.] The spread of infection among young people from their



20s to 40s has also increased markedly.



Last month, New Jersey's elderly inpatient growth rate stayed at a single digit, compared to 31% in their 20s and 48% in their 40s.



In the United States, more than half of the elderly aged 65 or older have been vaccinated, but most of the younger people have not yet received the vaccine.



In addition, as the spread of the mutant virus from the UK, which is much more infectious, is increasing, concerns about the 4th pandemic are emerging.



[Dr. Gunder/Infectious Disease Specialist: Looking at the corona 19 pandemic in the US last year, we can see that the pandemic in the US tends to come three to four weeks later than in Europe.]



Fortunately for health experts in the US, the vaccine developed so far. They advised that the vaccination rate should be accelerated to prevent the 4th pandemic, as it is also effective against the mutant virus.
