Sierra Leone announced it will implement a four-day “lockdown” across the country in an attempt to contain the spread of Ebola. The Friday move came as the World Health Organization stated that the virus has so far claimed over 2,000 lives in Africa.

Beginning September 18, the nation will prohibit residents from leaving their homes for four days, with the hopes that health officials will be able to detect early-stage cases, Ibrahim Ben Kargbo, a presidential advisor in Sierra Leone, told Reuters.

“The aggressive approach is necessary to deal with the spread of Ebola once and for all,” he said.

Unfortunately, the news was accompanied by worsening statistics from the World Health Organization (WHO), which announced on Friday that out of the roughly 4,000 people that have been confirmed to have the virus, 2,105 people have died in Guinea, Liberia, Sierra Leone, and Nigeria.

It marked a drastic rise in the death toll – a spike of about 500 people since last week – and continued adding to what is already the most deadly Ebola epidemic since the virus was first detected in 1976.
