Under an order issued by the US Centers for Disease Control and Prevention (CDC), foreign nationals who have been in the Democratic Republic of Congo (DRC), Uganda, or South Sudan within the past 21 days will not be allowed to enter the United States. The restriction does not apply to US citizens or permanent residents and will remain in effect for 30 days.
According to the CDC, the measure is intended to reduce the risk of the virus spreading into the United States while authorities assess the severity of the outbreak. The World Health Organization (WHO) declared the situation a global health emergency on Sunday, raising international concern over the growing crisis.
