The World Health Organisation’s emergency committee is set to hold talks to discuss the Ebola epidemic.
The meeting in Geneva will examine screening measures at borders and consider whether stricter travel regulations should be put in place.
New rules in the US require travellers from the worst affected countries to arrive at one of five airports.
A curfew has been imposed in a town in Sierra Leone after two people were shot dead in riots on Tuesday.
The current outbreak of the virus has already killed more than 4,500 people – mostly in Guinea, Liberia and Sierra Leone.
Enhanced screening
The WHO has faced criticism it reacted too slowly to the spread of the disease.
Its emergency committee will meet to discuss Ebola for the third time with the aim of assessing the efforts so far to contain and control the virus.
The riots in Sierra Leone’s town of Koidu began as protests against attempts to place an elderly woman, said to be 90 years old, under quarantine.
The woman has now died but it is not clear whether she actually had Ebola, the BBC’s Umaru Fofana reports from the capital, Freetown.
New rules are coming into force in the US requiring air passengers from Sierra Leone, Liberia and Guinea to travel via O’Hare in Chicago, JFK, Newark, Washington’s Dulles or Atlanta airports, where they will undergo enhanced screening.
They will have their temperatures checked as part of other protocols despite experts warning such moves are unlikely to have an impact.
The new security measures come as public concern grows in the US, where a Liberian man has died from Ebola and two nurses who had treated him have been infected.
