The Ebola virus spreads in the Congo. The Congo is a country in Africa. Almost 2000 people are sick. More than 700 people are dead.
The USA has new rules. Citizens cannot fly home directly from Congo. They must wait 21 days in another country. This stops the spread of the virus.
Experts say the virus stays for a long time. The sickness stays until the year 2027. A doctor from the USA is now in Germany. He is sick with Ebola.
Ebola is a very dangerous sickness. You get it through contact with body fluids. It gives you high fever and bleeding. Help is very hard in the region.
