The United States and European nations are stepping up measures to tackle the spread of coronavirus and counteract its economic impact, as the numbers of deaths and infections continue to grow.

The U.S. death toll surpassed 100 on Tuesday as all 50 states have now reported cases, and the E.U. announced sweeping restrictions on most travel within the 27-country bloc.

The White House announced Tuesday that it is looking to send checks directly to Americans in order to soften the economic fallout from the coronavirus outbreak.

The announcement comes as many parts of the U.S. have taken extraordinary measures to health the spread of the coronavirus. California officials announced a complete lockdown of the Bay Area, including San Francisco, that requires people to stay home except for essential needs.

U.K. advises against all non-essential international travel for 30 days

After a slew of tougher measures announced by the U.K. government Monday to help control the spread of the coronavirus, British nationals are being asked to avoid all non-essential international travel for at least 30 days. 

"This change in travel advice reflects the pace at which other countries are either closing their borders or implementing restrictive measures in response to the global coronavirus pandemic," U.K.'s foreign office said in a statement. 

British people who decide that they still need to travel abroad should be fully aware of the increased risks of doing so, the statement added. That includes the risk that they may not be able to get home if travel restrictions are put in place. 

Foreign office said in the last week alone, 430 changes have been made to their travel advice, more than in the entirety of 2019.
