Fighting outbreaks

Ebola Crisis Watch

West Africa experienced the largest ever outbreak of Ebola, infecting over 28,000 people and claiming over 11,000 lives. The International Rescue Committee was at the forefront of the fight to stop the spread of the deadly Ebola virus. Now we're responding to a new outbreak in the Democratic Republic of Congo.

IRC launches Ebola response in DRC

  • The IRC, a leading responder to the major Ebola outbreak in West Africa in 2014-2015, is working with the government and other organizations to combat the new outbreak in the Democratic Republic of Congo.

  • We are working at several health facilities in the villages of Bolenge, Itipo and Iboko and have deployed two Ebola-experienced doctors in Mbandaka.

  • The outbreak is the first to reach a large Congolese city -- which elevates the risk it will spread to other cities and countries. More aid is needed to help surrounding nations prepare.

  • In neighboring South Sudan and the Central African Republic, the IRC is working to strengthen Ebola surveillance, prevention and treatment in coordination with government and World Health Organization officials.

What is Ebola?

Ebola is a virus characterized by fever, weakness, muscle pain, headache and sore throat, followed by vomiting, diarrhoea and, in a few patients, bleeding.

Where was the deadliest outbreak of Ebola?

The largest and most complex Ebola outbreak occurred in West Africa in 2014. The disease was first discovered in Guinea and then moved across land borders to Sierra Leone and Liberia, infecting 28,000 people and claiming more than 11,000 lives. The IRC was a leading responder.

A new outbreak in the Democratic Republic of Congo, where the virus was first discovered in 1976, has spread to Mbandaka, a densely populated city of 1.2 million people. The Congo has experienced a total of nine Ebola outbreaks. The government has been efficient in controlling outbreaks, but until now, these outbreaks have mostly occurred in rural areas. Ebola detection and control is more difficult in an urban setting, which significantly escalates the risk of epidemic.  

The IRC is working with the Congolese government and the World Health Organization and its partners on the ground to contain the outbreak by sending a team of infection-control specialists, environmental health experts and medical logisticians to support existing health facilities. The goal is to strengthen prevention and control by helping facilities to identify and isolate Ebola cases in addition to providing lifesaving non-Ebola health services.

How does Ebola spread?

The virus is contracted through direct exposure to bodily fluids (of an infected person or a contaminated animal). Patients can take up to 21 days to develop symptoms, and Ebola’s initial symptoms are nonspecific, making it difficult to diagnose the disease quickly.

Patients who receive early treatment have a higher chance of survival and are less likely to infect others. People are not infectious until they develop symptoms.

Ebola is most contagious during the late stages of the disease: according to the World Health Organization, the virus remains contagious for up to three days after a victim dies. New Ebola cases can occur among relatives practicing burial rituals (such as washing corpses) or transporting the deceased for burial.

How do you treat Ebola?

Treatment for Ebola includes replenishing fluids, maintaining oxygen supply, and monitoring blood pressure. Health care workers treating Ebola patients must wear special protective equipment including gloves, goggles, fluid-resistant gowns, and masks covering nose and mouth.

The IRC supported hundreds of health facilities in Liberia and Sierra Leone, providing protective equipment to thousands of health workers, training them to screen for Ebola, and sharing protocols for isolating suspected patients and alerting authorities.

How do you prevent Ebola?

The spread of Ebola can be prevented by washing hands frequently with soap and water.

Contact tracing helps to identify people who have had significant physical contact with a confirmed Ebola patient while that patient exhibited symptoms.

After a person tests positive for Ebola, contact tracers interview family members and others possibly exposed to the virus, then monitor them for symptoms for 21 days.  

People who should be tracked for Ebola are those who:

  • had direct physical contact with a suspected or confirmed case (touched blood, body fluids, clothes or bedding);
  • had direct physical contact with a victim of Ebola at a funeral;
  • slept in the same household with a suspected or confirmed case.

Babies breastfed by infected mothers must be monitored for symptoms.

If a person shows signs of infection, an ambulance team should transport him or her to an isolation center to be tested for the virus, thus minimizing the transmission of the virus to others. If the person tests positive for Ebola, doctors, and nurses begin treatment and contact tracers repeat the process.

An experimental Ebola vaccine has been deployed to Congo. While still in the testing phase, it has been shown to be highly protective against Ebola. The vaccine will be given to people who have had direct contact with infected patients, as well as those who have had contact with these contacts, in order to establish a buffer of immune individuals to prevent the spread of the virus.

Fear and misinformation about Ebola in West Africa had spread faster than the virus, keeping people from seeking medical help and taking the critical steps to protect themselves and their families. It’s critical to educate communities on protection and prevention by enlisting the support of trusted locals.
