France has its first Ebola case. A doctor returned from the Democratic Republic of Congo. He works for a help group. He flew to Paris on a normal plane. He felt worse during the flight.
Doctors isolated the man immediately. He is in a special hospital now. His condition is stable. The virus in his blood is weak. Experts look for all contact people. These people must stay at home for 21 days. This is called quarantine.
The risk of infection in Europe is very low. The virus spreads only through body fluids. The situation in Africa is difficult. There are more than 1000 sick people. Over 250 people already died. There is no vaccine against this virus.
