'Pandemic of unvaccinated people'... Vaccines and masks mandatory in the US

<Anchor> The

spread of delta mutations is also strong in the United States. As the number of confirmed COVID-19 cases increases across the United States, it is mandatory to wear a mask indoors and vaccinate at school.

<Reporter> In the

50 US states and Washington DC, the weekly average number of COVID-19 cases per day increased by more than 10% compared to the previous week.

In 38 states, the increase was over 50%.

This month, the number of COVID-19 cases began to increase in the southern five states of the United States with low vaccination rates, and then spread across the United States.

[Wollensky / Director of the Centers for Disease Control and Prevention: It is becoming a 'pandemic of unvaccinated people'. We're seeing a surge in outbreaks in areas with low vaccination rates.] With the

spread of the virus, Los Angeles County has re-mandatory wearing of indoor masks whether or not vaccinated. Other counties in California have also started recommending indoor masks.

[Emmanuel/US Oncologist: It is not clear how contagious the delta mutation is even in vaccinated people. That's why I wear a mask when I go to the grocery store or post office.]

There are also measures to make vaccination compulsory.

Rhode Island has made vaccination compulsory at all colleges and universities in the state, and the University of California requires that all students and staff be vaccinated before the start of the fall semester.

However, some states have enacted laws to ban the mandatory use of masks and vaccinations in schools on the contrary, raising concerns about the spread of COVID-19 further.
