The recent surge in Covid-19 cases in the US was largely driven by a handful of states, many of which were the same places that first appeared as hot spots a year ago. As of Monday, about 75% of the previous week’s new cases in the US came from Michigan, Florida, New York, Pennsylvania, and New Jersey.
Covid-19 cases and the rate of new cases per 100,000 people are increasing again in several states that had kept the pathogen in check for long stretches. Outside of the Thanksgiving through New Years period, Michigan, Pennsylvania, and New Jersey didn’t hit that high during the pandemic. And outside of the same holiday season, New York hasn’t had as many new cases since the spring and Florida hasn’t had as many new cases since the summer.
Public health officials and epidemiologists say the rising number of cases in many parts of the country is due to a constellation of factors, including the spread of communicable variants; an increase in infections in younger, often unvaccinated people; relaxed prevention efforts and restrictions on eating and masking indoors; as well as pandemic fatigue. A familiar pattern
After a sharp drop due to the fatal fall, the newly reported Covid-19 cases in the US continue to increase. In some states, however, cases have risen higher again. They seem to follow a familiar pattern. When the falls first peaked in mid-April 2020, New Jersey, Michigan, Pennsylvania, and New York led that surge.
