( CNN ) The president of Sierra Leone has an idea on how to curtail the spread of Ebola : Get everybody to stay inside . President Ernest Bai Koroma on Saturday launched a campaign called `` Zero Ebola , '' in which almost all Sierra Leoneans are supposed to stay indoors March 27-29 and from 6 a.m. to 6 p.m. on three consecutive Saturdays -- April 4 , 11 and 18 . `` The campaign will provide an opportunity for communities to be directly involved in the drive to zero cases , to reflect and to pray for the eradication of this disease from our country , '' he said in a statement . Sierra Leona tried a three-day lockdown last September in what was primarily an informational campaign , with volunteers going door-to-door to talk with residents about the virus . In August , the Liberian government locked down one of the poorest neighborhoods in the capital of Monrovia in an attempt to stop the spread of the virus . The move resulted in riots . No commercial activity is supposed to occur during the upcoming lockdown , Koroma said . Because March 29 is Palm Sunday , church services will be allowed from 10 a.m. to 2 p.m. Health workers , journalists and public safety officers are exempted . Koroma noted that his country has made `` tremendous progress '' in the fight against the deadly disease as the Ministry of Health reported zero new infections Friday . He warned that the rate of transmissions may increase during the upcoming rainy season . `` The economic development of our country and the lives of our people continue to be threatened by the ongoing presence of Ebola in Sierra Leone , '' he said . `` The future of our country and the aspirations of our children are at stake . '' During Sierra Leone 's lockdown last year , Doctors Without Borders said such an effort is unlikely to stop the spread of the disease . `` Large-scale coercive measures like forced quarantines and lockdowns are driving people underground and jeopardizing the trust between people and health providers , '' the charity group said in a statement . `` This is leading to the concealment of cases and is pushing the sick away from health systems . '' Sierra Leone has the largest number of confirmed Ebola cases -- 11,751 so far , according to the World Health Organization . WHO says Liberia has the highest number of deaths -- 4,264 . So far , 10,194 have died from Ebola and 24,701 have been infected , according to WHO . Ebola is spread by direct contact with the bodily fluids of an infected person . The National Institutes for Health said Thursday it will admit an American health care worker with Ebola to its Maryland hospital . The person was volunteering at an Ebola treatment center in Sierra Leone . The Centers for Disease Control and Prevention said last Tuesday that 15 American aid workers who had high-risk exposure to Ebola in Sierra Leone have arrived back in the United States for monitoring . None is known to be infected with the disease . CNN 's Nana Karikari-apau contributed to this report .
