All states are partially reopen leaving Americans to weigh the risk of venturing out again

All 50 states have now partially emerged from coronavirus lockdowns, but with only a handful of states showing significant improvement in infection rates, some experts caution it could be too soon.

On Wednesday, Connecticut became the final state to begin lifting restrictions, allowing retail shops and restaurants to reopen their doors.

Despite the reopening milestone, health officials say, Americans remain at risk of catching the highly transmissible and sometimes deadly virus.

As of Wednesday afternoon, at least 18 states had registered an upward trend in average daily cases -- a rise of at least 10% -- over the previous seven days, according to an analysis of Johns Hopkins University data.

Only 17 states' average daily cases dropped more than 10%, while the rest were level or near level, the data showed.

The US Centers for Disease Control and Prevention released 60 pages of detailed guidance Tuesday on how to reopen the country -- including road maps for schools, restaurants, transit and child care facilities. In the guidance, the center advised that the first phase of reopening should begin after a state has seen a downward trajectory in cases over 14 days.
