New Ebola Outbreak Emerges in Congo as Toll Ticks Up in West Africa

— -- intro: Two dozen suspected Ebola cases have emerged hundreds of miles from West Africa in what health officials are calling a second “unrelated” outbreak in the Democratic Republic of Congo.

The virus has already killed more than 1,427 people in Liberia, Guinea, Sierra Leone and Nigeria, according to the World Health Organization. In fact, nearly half of all Ebola deaths recorded since the virus's discovery in 1976 have occurred in the last five months, according to WHO data.

quicklist: 1category: What’s Happening Now in the Ebola Outbreak title: Congo Reports Possible Ebola Cases, Deathstext: The Democratic Republic of Congo may be 800 miles from the Ebola outbreak in West Africa, but the Central African country has reported 24 suspected cases, including 13 deaths. None of the patients or their close contacts had traveled to West Africa, according to WHO.

“At this time, it is believed that the outbreak in [the Democratic Republic of Congo] is unrelated to the ongoing outbreak in West Africa,” the agency said in a statement today, adding that samples from the Congo cases are currently being tested for the virus.

The first known case in Congo occurred in a pregnant woman who became ill after butchering a “bush animal” that her husband killed, according to WHO. She died on Aug. 11. Health care workers who tended to her, including a doctor, two nurses and a ward boy developed similar symptoms and died, the agency said.

Ebola was first discovered in the Congo in 1976 and is named for the Ebola River.

quicklist: 2category: What’s Happening Now in the Ebola Outbreak title: WHO Worker with Ebola Evacuated to Germanytext: Health workers infected with Ebola continue to be evacuated from West Africa and treated elsewhere.

The latest is a Senegalese WHO scientist who was evacuated from Sierra Leone for treatment at the University Medical Center Hamburg-Eppendorf, which has a renowned tropical disease center, according to the Associated Press.

Since the epidemiologist wasn’t in the region to treat patients, but rather to coordinate with local health officials, WHO is trying to figure out how he got infected.

Other evacuees include the first British Ebola patient, a nurse stationed in Sierra Leone named Will Pooley, who was evacuated for treatment earlier this week, according to the Associated Press. The Royal Air Force sent a special jet to collect Pooley and transport him to the Royal Free Hospital in London, according to the AP.

Pooley also reportedly received the experimental Ebola drug ZMapp.

text: There's no cure for Ebola, but at least six people have received the experimental drug ZMapp: American health workers Dr. Kent Brantly and Nancy Writebol, a Spanish priest, two African doctors and one African nurse. Brantly and Writebol survived but the Spanish priest and one of the African doctors did not. The remaining African ZMapp recipients are expected to be discharged from the hospital on Friday.

Still, experts say it’s unclear whether ZMapp -- a cocktail of three antibodies that attack the virus –- actually helped those who received it. Before Brantly received his dose, the drug had only been tested in monkeys.

"Frankly we do not know if it helped them, made any difference, or even delayed their recovery," said Dr. Bruce Ribner, director of Emory University Hospital’s infectious disease unit, where Brantly and Writebol were treated.

text: Canada has pulled a small team of scientists from Sierra Leone because unaffiliated people at the team’s hotel were diagnosed with Ebola, according to the Associated Press. The three-person team will stay in isolation for 21 days even though none of them has shown symptoms of the virus.

The World Health Organization also announced that it would pull workers from Kailahun, Sierra Leone, after a WHO employee unexpectedly contracted the disease. That employee, who did not treat patients, is receiving treatment in Germany.

More than 240 health care workers have contracted Ebola in the West African outbreak and more than 120 of them have died, according to WHO. At least five more health care workers are suspected to have died from Ebola in a separate outbreak in the Democratic Republic of Congo, the agency said today.

The number of known infections -- currently 2,615 -- is underestimated because of those who hide the infected and bury the dead in secret, WHO said in a statement Aug. 22. The number also excludes so-called “shadow zones,” which are rumored to have Ebola cases that go unconfirmed because of community resistance and a lack of medical staff, the agency said.

Health officials also suspect an "invisible caseload" in Liberia because new treatment facilities are filling with previously unidentified Ebola patients as soon as they open.

Harvard and SSRS, an independent research company, conducted the poll of 1,025 adults last week and found that 39 percent of respondents feared a large Ebola outbreak in the United States.

According to the poll, 68 percent of Americans thought the disease could spread “easily” and 33 percent said they thought there was an available treatment for it, both highlighting a lack of understanding about Ebola in this country. In reality, the virus is only transmitted through contact with body fluids like blood and urine, and there is no cure. It’s unclear whether ZMapp, the unofficial drug given to the American Ebola patients, helped or hindered their recovery, experts say.

“Any person with an illness consistent with [Ebola virus disease] should not be allowed to travel unless the travel is part of an appropriate medical evacuation,” WHO said in a statement. “There should be no international travel of Ebola contacts or cases, unless the travel is part of an appropriate medical evacuation.”

Ebola symptoms include fever, weakness, muscle pain and sore throat before they progress to vomiting, diarrhea and rash. Some people may also experience bleeding.

The WHO Ebola Emergency Committee advised against international travel or trade restrictions at this time.

The tactic, used to prevent the spread of plague in medieval times, literally blocks off an area thought to contain 70 percent of the epidemic. But some experts say there’s little proof that isolation zones can prevent the spread of disease.

Survivor Sulaiman Kemokai, from Sierra Leone, said people in his community are afraid to touch him even though he’s been declared virus-free, the Associated Press reported.

The Ebola virus can only be spread through contact with bodily secretions such as blood, urine or sweat. But misinformation is rampant in areas hardest hit by the virus, health officials said.

The agency said products claiming to protect people from the infection began popping up online after the outbreak began in March.

“There are currently no FDA-approved vaccines or drugs to prevent or treat Ebola,” the agency said in a statement. “Although there are experimental Ebola vaccines and treatments under development, these investigational products are in the early stages of product development, have not yet been fully tested for safety or effectiveness, and the supply is very limited."

"There are no approved vaccines, drugs, or investigational products specifically for Ebola available for purchase on the Internet," the FDA added. "By law, dietary supplements cannot claim to prevent or cure disease.”
