200 Nigerians monitored for Ebola

Health officials are monitoring more than 200 people in the southern Nigerian city of Port Harcourt who may have been exposed to Ebola after a single man infected a doctor who then continued to treat patients before he himself died of the disease.

Authorities thought they had largely contained a small outbreak in Nigeria, but the World Health Organisation said the doctor’s actions created “multiple high-risk opportunities for transmission of the virus”.
