Sierra Leone is set to begin a three-day lockdown tonight at midnight to curb the spread of Ebola, according to Doctors Without Borders. Government authorities have ordered the country's 6 million people to stay in their homes from Sept. 19 through Sept. 21, while volunteers go door-to-door to screen for Ebola and take infected people in hiding to Ebola facilities, according to Doctors Without Borders, which called the endeavor "coercive."
