Public health officials in Oregon are monitoring four people who recently visited the West African countries of Guinea and Democratic Republic of the Congo (DRC). Regions in each of these countries are currently experiencing outbreaks of Ebola virus disease.
There is low risk for people in Oregon, according to the Oregon Health Authority (OHA).
What is Ebola?
Ebola Virus Disease (EVD) is a rare and deadly disease in people and nonhuman primates, according to the Centers for Disease Control and Prevention (CDC), which states on its wesbite that the viruses that cause EVD are located mainly in sub-Saharan Africa. People can get EVD through direct contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with Ebola virus.
Ebola virus disease is caused by an infection with a group of viruses within the genus Ebolavirus.
The OHA and local public health departments said they have been in contact with these individuals, who are considered “persons under monitoring,” since they arrived in the state earlier in March. The goal of this contact is to determine their risk, if any, of being exposed to Ebola and ensure their safety, as well as the safety of their families and the community.
“We want to make sure these individuals have the support they need to monitor their health, stay in contact with public health officials and safely get help with medical services if it comes to that,” said Richard Leman, M.D., Chief Medical Officer for Health Security, Preparedness and Response at the OHA Public Health Division.
As of March 24, Guinea has reported 18 Ebola cases and nine Ebola-related deaths. The Guinea outbreak is centered in Nzérékoré Prefecture, which is in the southern region of the country near the Liberian border. Democratic Republic of the Congo has reported 12 Ebola cases and six Ebola-related deaths. The outbreak in DRC is in North Kivu Province, which is in the eastern part of the country near the Ugandan border. The outbreaks are limited to small areas of each country and are not in large population centers.
The Centers for Disease Control and Prevention (CDC) has issued Level 3 travel warnings for the affected regions in both countries, recommending people avoid nonessential travel there.
Beginning March 4, CDC has required all airlines to supply contact information for all U.S.-bound travelers who have been in Guinea or Democratic Republic of the Congo in the last 21 days — the largest known incubation period for Ebola.
U.S.-bound travelers who have been in affected countries are routed through six international airports: Dulles in Washington, D.C.; John F. Kennedy in Queens, NY; Newark Liberty in Newark, NJ; O’Hare in Chicago, IL; Hartsfield-Jackson in Atlanta, GA; and LAX in Los Angeles, CA. Upon arrival, they are interviewed to determine if they are symptomatic and to confirm their contact information. If they are symptomatic, they will be offered medical evaluation.
CDC shares information for travelers from affected regions whose itineraries include Oregon. That way, public health authorities can contact these travelers and ensure they know symptoms to watch for and how to receive prompt medical evaluation if they become ill with symptoms consistent with Ebola.
OHA and local public health officials also are reaching out to international non-governmental organizations with services in the affected countries to request early notification for any volunteers traveling to Oregon after recent work in those areas.
In addition, OHA and local public health officials are contacting community-based organizations in Oregon to help the persons under monitoring with language access and other support services.
