During the COVID-19 pandemic, CDC has also provided an interactive world map specifically showing COVID-19 travel recommendations by country. This world map uses an evidence-based approach, referred to as the COVID-19 THN Risk Assessment, to evaluate the COVID-19 risk in each country.On March 27, 2020, CDC issued a Level 3 Global COVID-19 Pandemic Notice advising against all nonessential international travel due to the COVID-19 pandemic.
