The Ebola virus has infected more than 1,400 people in Guinea, Liberia, Nigeria and Senegal, with the most deaths recorded in Liberia, where at least 13 people have died.
The Centers for Disease Control and Prevention said Friday that all countries affected by an outbreak of the virus should be on heightened alert and should all seek a full quarantine.
Guinea has been declared a country of immediate and ongoing national emergency, Liberia and Nigeria have been designated a regional and global priority for control, Senegal has been designated an immediate threat, and Nigeria is the focus of a special mission to fight the virus.
Guinea, Nigeria, Senegal and Senegal have been hardest hit by the outbreak, which has also killed at least 9,836 people and left about 3.8 million displaced people homeless.
The World Health Organization has warned that the current outbreak could spread rapidly to other countries and has called for an international response to help stem the spread of the deadly virus.
Liberia, a predominantly Catholic country with a history of fighting political unrest, has been hardest-hit by the epidemic.
The Ebola outbreak began on Feb. 15 in Guinea and the country’s public health minister, Dr. Raul Fonseca, said Friday the country was at the “high threshold” of the disease.
The government has declared three days of national mourning for all of Feb. 16, and it’s also calling for more than $2 billion in aid from the United Nations.
In Senegal, President Macky Sall announced Friday that the country would seek a total quarantine of all public places.
The president’s office said the government will impose a total ban on the travel of visitors, as well as the opening of schools, churches and cinemas.
Senegal, where the first confirmed cases were found on Feb 10, has also been at the forefront of the fight against the virus, deploying 1,600 health workers, providing treatment facilities and providing emergency services.
On Friday, Senegal’s president said he would request the U.N. Security Council to consider the possibility of deploying an Ebola response force.
Senegal has deployed more than 100 health workers and health workers have been sent to neighboring countries to help fight the Ebola crisis.
