The Lagos doctor who treated American Patrick Sawyer (who died from Ebola in late July) has been confirmed as infected by the deadly virus by Nigerian authorities. This is Nigeria's second confirmed case of Ebola but what is most concerning is the fact that the doctor's infection suggests contagion is less well-contained that authorities have claimed - especially in light of the fact that they did not quarantine Sawyer's fellow passengers. Nigeria is now the fourth nation to report Ebola cases, as Sierra Leone and Liberia are deploying hundreds of troops under an emergency plan to "contain" the worst outbreak of Ebola virus in history.
