Do directors drop out on vacation

"Much of the diffusion is among younger people," he said. "This is the group that moves, relaxes, and gets infected."

States are starting to lift their COVID-19 restrictions and the spring break crowds have overwhelmed some areas like South Florida. Governors and health officials have raised concerns about the latest coronavirus data in their states.

Michigan, for example, is already in the middle of yet another COVID-19 surge, with most cases increasing between the ages of 10 and 19, said Dr. Joneigh Khaldun, the state's chief medical executive, told CNN on Sunday. The diffusion in the community happens when people gather and businesses reopen.

New York and New Jersey now have the highest COVID-19 case rates in the county, according to data New York Post. New Jersey has an average of 647 cases per 100,000 population and New York has an average of 548 cases per 100,000 population. The increases appear to be linked to loose restrictions and coronavirus variants, the newspaper reported.

In Illinois, state officials said Friday that rapid-response vaccination teams would be deployed in multiple counties to deal with the surge in COVID-19 cases and hospitalizations.

"We don't want to go the same path we saw before and see the pandemic resurgence," said Dr. Ngozi Ezike, director of the Illinois Department of Public Health, issued a statement Friday. "We can't go forward if our metrics go backwards."

Vermont officials reported Friday, the highest single-day case number since the pandemic began, with more than 250 new infections.

New Hampshire has also reported increases in the average number of new cases each day and test positivity rate, particularly among teenagers and people over the age of 20. The cases are likely to continue and lead to a "spring surge," Governor Chris Sununu said in a statement on Thursday.

In Pennsylvania, cases and positivity rates rose last week and 25 counties had significant transmission, Governor Tom Wolf said in a statement last week.

Iowa reported a 34% increase in daily cases last week. This was the biggest change in a week since early January, when cases increased 36% after vacation travel to KCRG, an ABC subsidiary in Cedar Rapids.
