Ebola surveillance is expanding beyond DR Congo as authorities respond to a growing outbreak.
More than 7,700 cases and 3,700 deaths have been reported, according to government figures released on Tuesday.
Meanwhile, the International Organization for Migration (IOM) is increasing health screening along major travel routes.
Ebola surveillance expands across travel routes
IOM teams are increasing surveillance at displacement sites and key transport points.
These include routes along the Congo River.
At Bende-Bende port in Kinshasa, health workers check the temperature of passengers.
Travellers also provide health information through screening forms.
According to IOM, teams conduct around 1,000 health screenings each day at the port.
Suspected cases referred for testing
Passengers who meet the criteria for a suspected case are referred for further testing.
Dr. Primous Godjedo, an IOM health security specialist, said testing helps determine whether a person has Ebola or another disease.
The screening system is designed to identify possible cases among people travelling through major transport routes.
Neighbouring countries strengthen preparedness
Efforts are also expanding beyond DR Congo.
IOM said it is working with neighbouring countries to strengthen preparedness and reduce the risk of cross-border transmission.
Those countries include Uganda, South Sudan, Burundi, Rwanda and the Central African Republic.
The measures come as health authorities continue efforts to contain the outbreak inside DR Congo.
Surveillance along borders and major travel routes remains a key part of the response.
