On July 29, the US upgraded the State Department's travel alert to the highest level of travel ban, in relation to the spread of Korea's coronavirus infection-19 (Corona 19).

The travel alert for Korea itself has maintained a three-stage 'trip inventory', but it can be difficult to pre-departure by ordering enhanced medical checks for travelers to the United States.

The United States has also made travel alerts "banned" in some parts of Italy, and has banned entry into the United States of those who have visited Iran within the last two weeks.

It is also reported to review a superhard card called the closure of the Mexican border to prevent the influx of Corona19 from South America.

US Vice President Mike Pence said in a press conference with President Donald Trump at the White House that "Trump has approved the upgrade of travel alerts to certain regions in Korea and Italy to the highest level of four." "I urge you not to travel to those areas most affected by 19."

This measure applies when an American leaves the country, but does not force them to leave the country.

The Department of State has since designated Daegu as a four-level warning zone that recommends travel bans on its website.

Daegu's Corona19 was presented for reasons of community dissemination and implementation of containment procedures.

However, the travel alert for Korea remained in three stages.

In Italy, the country itself remains in three phases, but the Lombardy and Veneto regions are not allowed to travel.

Pence says Trump has ordered the State Department to work with the two countries to coordinate medical tests for individuals from Korea and Italy to the United States.

Foreshadowing a more difficult pre-departure screening process for travelers to both countries.

The South Korean government is said to be willing to cooperate with the United States to resolve anxiety.

Trump said, “We are very concerned about the unit and are in constant contact with us. It is becoming "in cooperation with the Korean authorities."

In a conference speech later, President Trump explained the steps taken to upgrade the travel alerts of South Korea and Italy to the highest level and said, "The two countries are very heavily infected."

This suggests that there may be additional travel bans in Korea, given that the State Department recommended travel bans in two regions in Italy, while Korea had only one daegu.

"The high-level official of the State Department has informed US Ambassador Lee Soo-hyuk in advance about the Trump's interview on the day," said the diplomatic official.

The ambassador spoke with the Assistant Secretary of State for East Asian and Pacific Affairs, David Stillwell, who is said to evaluate the ROK's transparent and open response and to continue close consultations.

The ban on entry into Korea and Italy, which was mentioned in some cases, was not included in the announcement, but we cannot rule out the possibility of further action depending on the future situation.

"We hope to lower the number of trips to and from the region most affected by Corona 19. This is the basic deterrence strategy."

Reuters quoted officials as saying they have been considering applying the US ban on China to Korea.

Earlier, the State Department upgraded Korea's travel alert, which was the first stage, to the second stage (strengthened attention) on the 22nd, and then upgraded to the third stage (travel inventory) on the 26th.

The Centers for Disease Control and Prevention (CDC) raised Korea to the highest rating of three (warning) on ​​the 24th.

The further action by the United States appears to have been affected by concerns about the spread of people infected with Corona 19 and even the first deaths.

Pence says foreigners who have visited Iran within the last two weeks are prohibited from entering the United States.

Iran had already been banned from entering the United States, but this time it has expanded to foreigners visiting Iran.

President Trump even hinted at the possibility of limiting Mexico's border with Mexico, and began to work on it.

"Yes, we're thinking about the southern border," he said when asked to consider closing the Mexican border, Reuters said.

But as Trump continued, "We are thinking about all borders. It's not the borders that have a lot of problems right now," he said. "We hope not to do it."
