Ebola Statistics: As of November 7 2014, Total Deaths 4960, Total Cases 13268, And 8198 Confirmed Cases

2014 West Africa Ebola Outbreak

As of November 5, updated November 7th. there have been a total of 4960 deaths from Ebola in the latest outbreak which began in March 2014. The total number of cases has increased to 13268, and confirmed cases are at 8168. There has been a call for 5000 more medical worker to join the fight against Ebola in West Africa.  Although there are new cases being reported weekly in Guinea, Sierra Leone, and Liberia the total deaths are now stabilizing, which could be due to international aid, and assistance, and informing the public about how Ebola is spread, preventative measures, and also as the people see that many are now surviving Ebola they grow less fearful of seeking medical care in the regions.

*The outbreaks of Ebola Virus Disease (EVD) in Senegal and Nigeria were declared over on 17 October and 19 October 2014, respectively. A national EVD outbreak is considered to be over when 42 days (double the 21-day incubation period of the Ebola virus) has elapsed since the last patient in isolation became laboratory negative for EVD.

Overview West Africa:

The 2014 Ebola epidemic is the largest in history, affecting multiple countries in West Africa. There were a small number of cases reported in Nigeria and a single case reported in Senegal; however, these cases are considered to be contained, with no further spread in these countries.

Two imported cases, including one death, and two locally acquired cases in healthcare workers have been reported in the United States. CDC and partners are taking precautions to prevent the further spread of Ebola within the United States. CDC is working with other U.S. government agencies, the World Health Organization (WHO), and other domestic and international partners and has activated its Emergency Operations Center to help coordinate technical assistance and control activities with partners. CDC has also deployed teams of public health experts to West Africa and will continue to send experts to the affected countries.

Overview Democratic Republic of the Congo:

As of October 29, 2014, there have been 67 cases of Ebola virus disease reported in the Democratic Republic of the Congo. In total, 49 deaths have been reported. This outbreak is unrelated to the current outbreak of Ebola in West Africa.

Outbreak Update:

  • On November 5, WHO released a situation report that included a decrease in the number of total cases since the report released on October 31, 2014. WHO reports that the decrease in total cases results from a change in data sources.
  • On November 5, WHO reported that all 83 contacts of the health worker infected in Madrid, Spain have completed the 21-day follow-up period.
  • On October 29, WHO released a situation report that included an increase of 3792 cases since the report released on October 22, 2014. WHO reports that the increase in  total cases results from a more comprehensive assessment of patient databases. The additional 3792 cases have occurred throughout the epidemic period.
  • On October 23, the New York City Department of Health and Mental Hygiene reported a case of Ebola in a medical aid worker who had returned to New York City from Guinea, where the medical aid worker had served with Doctors Without Borders. The diagnosis was confirmed by CDC on October 24.
  • On October 23, Mali reported its first confirmed case of Ebola in a child who had traveled there from Guinea. The child passed away on October 24.
  • WHO officially declared Senegal and Nigeria free of Ebola virus transmission on October 17 and 20, respectively.
  • On October 15, a second healthcare worker at Texas Presbyterian Hospital who provided care for the index patient tested positive for Ebola. The patient is receiving care at a hospital in Atlanta, Georgia.
  • On October 10, a healthcare worker at Texas Presbyterian Hospital who provided care for the index patient tested positive for Ebola. The patient has since recovered and was discharged from the NIH Clinical Center on October 24.
  • CDC is implementing enhanced entry screening at five U.S. airports that receive over 94% of travelers from Guinea, Liberia, and Sierra Leone.
  • On September 30, 2014, CDC confirmed the first travel-associated case of Ebola to be diagnosed in the United States. The patient passed away on October 8, 2014.
  • New cases continue to be reported from Guinea, Liberia, and Sierra Leone.
  • The Democratic Republic of the Congo (DRC) has reported cases of Ebola. These cases are not related to the ongoing outbreak of Ebola in West Africa. For information on the outbreak in DRC, see the 2014 Ebola Outbreak in DRC page.

Symptoms of Ebola include:

  • Fever (greater than 38.6°C or 101.5°F)
  • Severe headache
  • Muscle pain
  • Weakness
  • Diarrhea
  • Vomiting
  • Abdominal (stomach) pain
  • Unexplained hemorrhage (bleeding or bruising)

Symptoms may appear anywhere from 2 to 21 days after exposure to Ebola, but the average is 8 to 10 days.

Recovery from Ebola depends on good supportive clinical care and the patient’s immune response. People who recover from Ebola infection develop antibodies that last for at least 10 years.

How Ebola is Transmitted:

Because the natural reservoir host of Ebola viruses has not yet been identified, the manner in which the virus first appears in a human at the start of an outbreak is unknown. However, researchers believe that the first patient becomes infected through contact with an infected animal.

When an infection does occur in humans, the virus can be spread in several ways to others. Ebola is spread through direct contact (through broken skin or mucous membranes in, for example, the eyes, nose, or mouth) with

  • blood or body fluids (including but not limited to urine, saliva, sweat, feces, vomit, breast milk, and semen) of a person who is sick with Ebola
  • objects (like needles and syringes) that have been contaminated with the virus
  • infected animals
  • Ebola is not spread through the air or by water, or in general, by food. However, in Africa, Ebola may be spread as a result of handling bushmeat (wild animals hunted for food) and contact with infected bats. There is no evidence that mosquitos or other insects can transmit Ebola virus. Only mammals (for example, humans, bats, monkeys, and apes) have shown the ability to become infected with and spread Ebola virus.

Healthcare providers caring for Ebola patients and the family and friends in close contact with Ebola patients are at the highest risk of getting sick because they may come in contact with infected blood or body fluids of sick patients.

During outbreaks of Ebola, the disease can spread quickly within healthcare settings (such as a clinic or hospital). Exposure to Ebola can occur in healthcare settings where hospital staff are not wearing appropriate protective equipment, including masks, gowns, and gloves and eye protection.

Dedicated medical equipment (preferable disposable, when possible) should be used by healthcare personnel providing patient care. Proper cleaning and disposal of instruments, such as needles and syringes, is also important. If instruments are not disposable, they must be sterilized before being used again. Without adequate sterilization of the instruments, virus transmission can continue and amplify an outbreak.

Once someone recovers from Ebola, they can no longer spread the virus. However, Ebola virus has been found in semen for up to 3 months. People who recover from Ebola are advised to abstain from sex or use condoms for 3 months.

Treatment: 

No FDA-approved vaccine or medicine (e.g., antiviral drug) is available for Ebola.

Symptoms of Ebola are treated as they appear. The following basic interventions, when used early, can significantly improve the chances of survival:

  • Providing intravenous fluids (IV)and balancing electrolytes (body salts)
  • Maintaining oxygen status and blood pressure
  • Treating other infections if they occur

Experimental vaccines and treatments for Ebola are under development, but they have not yet been fully tested for safety or effectiveness.

Recovery from Ebola depends on good supportive care and the patient’s immune response. People who recover from Ebola infection develop antibodies that last for at least 10 years, possibly longer. It isn’t known if people who recover are immune for life or if they can become infected with a different species of Ebola. Some people who have recovered from Ebola have developed long-term complications, such as joint and vision problems.
