The US Centers for Disease Control and Prevention added six destinations including Bangladesh to its "high" risk category for travel on Monday.
Among the six places, two Central American countries -- El Salvador and Honduras -- received a Level 3, "high" risk designation. Bangladesh, Bosnia and Herzegovina, Poland and Fiji were also added to Level 3.
Level 3 became the top rung in terms of risk level in April after the CDC overhauled its ratings system for assessing Covid-19 risk for travelers.
The designation applies to places that have had more than 100 cases per 100,000 residents in the past 28 days. Level 2 and Level 1 are considered "moderate" and "low" risk, respectively.
Bangladesh on Monday reported five Covid-19 deaths with 548 coronavirus positive cases during the period.
