New York also announced that they would largely restrict residents to their homes starting this weekend, after America's largest state, California, did so Friday. The move means a total of 70 million people will be restricted.
What does shelter in place mean? San Francisco provides an idea of what the rules could look like.
In the San Francisco area, six counties are on lockdown until at least April 7, with only people with essential jobs or government functions allowed to work outside their homes.
Jobs deemed essential there include health care workers, grocery store employees, pharmacists, hardware store workers, plumbers, electricians, day care providers, bank tellers and roles that are essential to a business’ operations such as payroll and security. Police, firefighters, paramedics and sanitation workers will not be quarantined.
Like Illinois, San Francisco has shut down schools and bars, moving all restaurants to takeout or delivery only. Gyms and theaters have been closed, but gas stations, laundromats, dry cleaners, banks, supermarkets, pharmacies and convenience stores have remained opened per the order.
Bay Area residents are allowed to leave their homes to care for the elderly, minors, dependents, persons with disabilities or other vulnerable persons. People also can engage in outdoor activities such as hiking, running or walking as long as they maintain a social distance of 6 feet.
They also may venture out to get food for their families and pets.
“These measures will be disruptive to day-to-day life, but there is no need to panic,” San Francisco Mayor London Breed said Monday.
There were 412 confirmed coronavirus cases in the San Francisco area as of Thursday, including four deaths in Santa Clara County attributed to the virus.
