The next few weeks will really tell if this outbreak is going to expand to urban areas or if we're going to be able to keep it under control. Doctors report there are three separate chains of transmission and each one has the potential to expand if it's not controlled. One focus is on the busy trading hub on the Congo River.
Five health care workers have also died, raising fears the virus could spread out of control. The UK announced it will pledge 5 million pounds in aid and will also help develop a vaccine.
未来一周会真正告诉我们此次爆发会扩散到城市还是我们能将其控制住。医生报道一共有三条单独的传播链，如果不加控制，每条链都可能扩散 。其中一个重点是刚果河上的一个贸易枢纽 。
