ALast Monday, another quartet of countries passed a level 4 travel health advisory from the Centers for Disease Control and Prevention (CDC). This week, the four new additions are in Europe, reflecting the growing risk of Covid-19 across the continent.

Today, the CDC again expanded its list of destinations under Level 4 warnings, adding four new countries: the Czech Republic, Guernsey, Hungary and Iceland. As a result, 11 European countries have been added to the “avoid travel” list in the past four weeks.

The highest of the four risk categories, a level 4 travel health advisory means a country reports more than 500 new Covid-19 infections every 28 days per 100,000 people. This level of infection is deemed to pose a “very high” risk of Covid-19 and Americans are warned to “avoid travel,” according to CDC guidelines.

To date, 81 countries around the world are at Level 4 on the CDC’s Covid risk map. If the CDC could add its own country – the United States – the tally would be 82.

The last weekly epidemiological update of the World Health Organization (WHO) reported just over 3 million new cases worldwide, an increase of 1% from the previous week.

Covid continues to increase in Europe

Europe continues to see its Covid figures heading in the wrong direction, with a 7% increase in new weekly cases and a 1% increase in Covid-related deaths compared to the previous week, according to the report. WHO.

The European region is experiencing cases of Covid-19 infection similar to those reported in December 2020. Of the 61 countries in the region, 26 (42%) reported week-over-week increases.

The more than two dozen European destinations currently subject to a level 4 travel health advisory include tourism powers such as Austria, Belgium, Croatia, Greece, Ireland, the Netherlands, Norway , Russia, Switzerland, Turkey and the United Kingdom.

Covid is riding a wave in the Caribbean

The Caribbean is still reporting a high number of new cases of Covid, and most countries are under the CDC’s Level 4 warning. In last week’s report, the WHO report noted a 145% week-over-week increase in new Covid cases in the Cayman Islands and a 21% increase in Puerto Rico.

More than a dozen other Caribbean countries carry the CDC’s “avoid travel” warning, including Aruba, Barbados, Bermuda and the British and US Virgin Islands. Good news, the Bahamas went from level 4 to level 3 this week.

Covid cases continue to decline in Asia

The Asia-Pacific region has been among the slowest and most cautious in the world in reopening to tourism. The Southeast Asia region reported a 13% drop in new Covid cases from the previous week, according to the WHO report. In particular, promising declines were recorded in India (- 16%), Thailand (- 9%) and Myanmar (- 16%).

Only a handful of Asian countries have the CDC’s Level 4 designation, including Singapore, Malaysia, Maldives, and Myanmar.

Covid levels are persistent in the United States

The United States has been shaded in dark red on the CDC’s world map for much of the pandemic. The United States records 25 new cases per 100,000 daily on a seven-day moving average, according to the Brown School of Public Health Covid-19 Tracker. That translates to about 700 new daily cases every 28 days per 100,000 people, well above the CDC’s threshold for Level 4 Travel Health Advisory.
