The rapidly increasing incoming infection in the United States has caused officials to change regulations to wear masks and promote vaccination of Covid-19 nationwide, especially in places with low vaccination rates.

US CDC recommends people wearing a closed environment, regardless of whether or not in vaccination, if they are in areas with high or significant NCOV infections.

According to scientists, the vaccine is currently the most effective tool to prevent Delta's vaccine and also afford to prevent the risk of suffering or death for NCOV infected people.

Covid-19 is complicated in the United States, because the vaccination campaign is stalled after the initial quick effort.

Delta strains make new cases in the US constantly exceeding 100,000 over the past few days, while the hospital cautions also increase rapidly.
