Michigan and Washington are the latest US states to announced strict curbs on movement, as the number of coronavirus cases surpassed 11 million nationwide.
The most recent million cases have all come in the past week alone, as health officials advise Americans to forego or revise their Thanksgiving holiday plans to help stop the rapid spread of the disease.
Michigan’s Democratic governor Gretchen Whitmer has ordered high schools and colleges to stop in-person teaching, suspended organised sports and banned restaurants from offering any indoor dining for the next three weeks.
Fellow Democrat Jay Inslee, governor of Washington, announced his state would enforce even tighter restrictions on businesses and social gatherings for the next month. Gyms and cinemas will be required to close, while restaurants and bars will be limited to outdoor dining and to-go services.
