Seventeen year-old Haja Umu Jalloh, a survivor of Ebola, has been caring for about 40 children at the St. George Foundation Interim Care Center in Sierra Leone. Because she has survived Ebola, she is considered immune to the disease and has therefore been asked to “stand guard” over children orphaned by the disease, who may or may not be infected themselves, while they are quarantined at the interim care center.
