The number of states in the United States where people infected with the new mutant virus Omicron strain has increased to 12.
Health authorities in each state are calling for vaccination.
By the 4th, 12 states in the United States, including New York in the east, California in the west, Nebraska in the Midwest, and Louisiana in the south, were confirmed to be infected with the Omicron strain.
Dr. Fauci, chief medical adviser to the US government, said in an interview on a television show that "a community-acquired infection has already occurred."
Health officials in each state recommend vaccination as a countermeasure and encourage people who have already been vaccinated to receive additional vaccinations to improve their effectiveness.
A doctor at a local medical institution said, "I think there may be some vigilance for Omicron strains," as vaccination venues in central California are full of vaccination appointments.
Citizens also visited the vaccination site in New York City one after another, and the man who received the additional vaccination said, "I don't think it will be a big problem if the Omicron strain is found and it does what it should do." ..
In addition, at Los Angeles International Airport in California, border measures are in full swing in various parts of the United States, such as the start of free antigen testing for people arriving from overseas on the 4th.
