The ongoing Ebola outbreak continues to be of great concern. Liberia, Sierra Leone, and Guinea are of course where the real problem lies, but the chart below shows current cases outside Africa. Circles represent evacuated medical or other personnel, while squares represent other cases, including two nurses infected by caring for patients. Recovered patients are shown in green, and deaths in black.
The two infections of nurses demonstrate that even in Western countries, effective infection control within hospitals is a challenge. Hopefully there will be no more deaths among the many brave medical personnel treating this terrible disease.
Update 2: A second American nurse has now been diagnosed with Ebola.
