There are 1,135 confirmed cases in the US, 101 in Canada.

Thirty-eight people have died in the US due to the virus and one person has died in Canada. Officials say risk remains low for the general US public, but this could change. The governor of Washington has banned large gatherings in several counties across the state as part of a sweeping effort to contain the spread. The north-western state is the focal point of the outbreak in the US, accounting for 24 of the deaths across the country. Several states, including Washington, have declared emergencies to deal with the outbreak.

So how prepared - and worried - is the US?

Airlines will be hit hard by President Trump’s 30-day travel ban between Europe and the US. The aviation industry is already struggling with a massive downturn in passenger numbers during the coronavirus pandemic.

In Asian markets, Australian airline Qantas saw its share price fall 11% following the announcement, while Singapore Airlines' share price was down 4%.

The airline industry is already predicted to take an economic hit of up to $113bn this year as thousands of flights are cancelled.

India is suspending all tourist visas until 15 April in an attempt to control the coronavirus outbreak. The move comes into effect on Friday.

All "existing visas - except diplomatic, official, UN/International Organisations, employment, project visas - stand suspended till 15 April 2020," said the Indian Ministry of Health in a tweet.

All incoming travellers - including Indians - from China, Italy, Iran, Korea, France, Spain and Germany will be quarantined for 14 days.

To sum up: from behind the Resolute Desk in the Oval Office, President Trump announced a number of measures to control the spread of the coronavirus to the US. Here are the main points:

• All travel from Europe to the US suspended for the next 30 days – beginning on Friday at midnight.
• The United Kingdom is exempted
• Trade and cargo are not affected, Mr Trump has confirmed on Twitter

• The US is cutting red tape to make anti-viral therapies available in record time
• Financial relief "to ensure that working Americans impacted by the virus can stay home without fear or financial hardship"
• Economic loans for affected states and territories
• This will provide more than $200bn of additional liquidity to the economy
• Congress urged to provide Americans with immediate payroll tax relief

Kuwait will be suspending all commercial incoming and outgoing commercial flights from Friday "until further notice", due to coronavirus concerns.

The state news agency KUNA said this did not include cargo flights.

China on Thursday reported eight new coronavirus cases in the province of Hubei where the virus first emerged.

This is the first time Hubei's daily tally has been in the single digits.

Outside of Hubei, China had seven new cases - six of which were imported from abroad.

This brings the total number of confirmed cases in China to 80,793.

The US National Basketball Association (NBA) says it will suspend the season until a further notice after a Utah Jazz player tested positive for the coronavirus.

The NBA has not announced who the affected player is, but Reuters suggests it is Rudy Gobert.

The league said it would use this "hiatus to determine next steps moving foward".

As the coronavirus sweeps across the US, American officials have warned that mandatory prevention measures may be necessary to stop its spread. But is the US willing to go as far as Italy - another democracy - or even authoritarian China? Italy has banned mass gatherings and barred citizens from travelling outside of their home region. China has forced more than 50 million citizens to self-isolate and even threatened severe penalties, including death, for quarantine breakers. So what measures is the US willing to take, and could coronavirus besiege an American city?

Get the answers in our explainer.

"I have decided to take several strong but necessary actions to protect the health and well-being of all Americans," said Mr Trump.

"To keep new cases from entering our shores, we will be suspending all travel from Europe to the United States for the next 30 days. The new rules will go into effect Friday at midnight. These restrictions will be adjusted subject to conditions on the ground."

"The European Union failed to take the same precautions and restrict travel from China and other hot spots. As a result a large number of new clusters in the United States were seeded by travelers from Europe," Mr Trumps said, before making his announcement.
