A group of American researchers have reported that the spread of the coronavirus is declining.

The research team showed that the spread of the disease was reduced due to either the corona vaccine or immunisation developed through viral infection.

The report, based on Corona data from the United States, predicts that by March next year, the United States will have reached its lowest level since the outbreak.

By then, the number of infected people in the United States will be 9,000 a day and less than 100 a day, the researchers said.
