List of Ebola outbreaks

Ebola virus

This List of Ebola outbreaks records the known occurrences of Ebola hemorrhagic fever. Pathogens of the disease are the five ebolaviruses recognized by the International Committee on Taxonomy of Viruses: Ebola virus (EBOV), Sudan virus (SUDV), Reston virus (RESTV), Taï Forest virus (TAFV), and Bundibugyo virus (BDBV).[1][2][3][4][5] RESTV has caused the illness only in primates.[6][7]

Transmission between natural reservoirs and humans is rare, and outbreaks of Ebola virus disease are often traceable to a single case where an individual has handled the carcass of a gorilla, chimpanzee, or duiker.[8] The virus then spreads person-to-person, especially within families, hospitals, and during some mortuary rituals where contact among individuals becomes more likely.[9]

Learning from failed responses, such as during the 2000 Uganda outbreak, the World Health Organization (WHO) established its Global Outbreak Alert and Response Network, and other public health measures were instituted in areas at high risk. Field laboratories were established to confirm cases, instead of shipping samples to South Africa.[10] Outbreaks are closely followed by the United States Centers for Disease Control and Prevention (Special Pathogens Branch) as well.[11]

Nigeria was the first country in western Africa to successfully curtail the virus, and its procedures have served as a model for other countries to follow.[12][13][14]

Events

Major or massive cases

Larger outbreaks[15]
Year Country[note 1] Virus Human cases Human deaths Case fatality rate Description
1976  Sudan SUDV 284 151 53% Occurred in Nzara (the source town), Maridi, Tumbura, and Juba between June and November 1976. The index cases were workers in a cotton factory. The disease was spread mainly by close contact with an acute case, usually associated with nursing a patient. Many medical care personnel were infected.[16]
1976  Zaire EBOV 318 280 88% Occurred in Yambuku and surrounding areas in August. It spread through personal contact and by use of contaminated needles and syringes in hospitals and clinics.[17]
1979  Sudan SUDV 34 22 65% Occurred in Nzara and Maridi. This was a recurrent outbreak at the same site as the 1976 Sudan epidemic.[18]
1994  Gabon EBOV 52 31 60% Occurred in Makokou and gold-mining camps deep in the rain forest. Until 1995, this was incorrectly classified as solely a yellow fever outbreak.[19]
1995  Zaire EBOV 315 254 81% Occurred in Kikwit and surrounding areas. Traced to a patient who worked in a forest adjoining the city. The epidemic spread through families and hospital admissions.[20][21]
1996  Gabon EBOV 37 21 57% Occurred in the Mayibout area between January and April. A chimpanzee found dead in the forest was eaten by people hunting for food. Nineteen people who were involved in the butchery of the animal became ill. Other cases occurred in family members.[19]
1996–1997  Gabon EBOV 60 45 75% Occurred in the Booué area with transport of patients to Libreville between July 1996 and January 1997. The index case-patient was a hunter who lived in a forest camp. The disease was spread by close contact with infected persons. A dead chimpanzee found in the forest at the time was determined to be infected.[19]
2000–2001  Uganda SUDV 425 224 53% Occurred in the Gulu, Masindi, and Mbarara districts of Uganda. The three greatest risks associated with Sudan virus infection were attending funerals of case-patients, having contact with case-patients in one's family, and providing medical care to case-patients without using adequate personal protective measures.[22]
2001–2002  Gabon
 Republic of the Congo
EBOV 135 107 79% Occurred on both sides of the border between Gabon and the Republic of the Congo (RC) between October 2001 and July 2002. First reported occurrence of Ebola virus disease in the RC.[23]
2002–2003  Republic of the Congo EBOV 143 128 90% Occurred in the districts of Mbomo and Kelle in the Cuvette-Ouest Department between December 2002 and April 2003.[24]
2003  Republic of the Congo EBOV 35 29 83% Occurred in Mbomo and Mbandza villages located in Mbomo district, Cuvette-Ouest Departement, between November and December.[25]
2004  Sudan SUDV 17 7 41% Occurred in Yambio county in Western Equatoria of southern Sudan. This outbreak was concurrent with an outbreak of measles in the same area, and several suspected EVD cases were reclassified later as measles cases.[26]
2007  Democratic Republic of the Congo EBOV 264 187 71% Occurred in Kasai-Occidental province. The outbreak was declared over on 20 November. The last confirmed case was on 4 October, and the last death was on 10 October.[27]
2007–2008  Uganda BDBV 149 37 25% This was the first recognition of BDBV. Occurred in the Bundibugyo District in western Uganda between December 2007 and January 2008.[2][3][4]
2008–2009  Democratic Republic of the Congo EBOV 32 14 45% Occurred in the Mweka and Luebo health zones of the Kasai-Occidental province between December 2008 and February 2009.[28]
2012  Uganda SUDV 24 17 71% Occurred in the Kibaale District between June and August.[29]
2012  Democratic Republic of the Congo BDBV 77 36 47% Occurred in the Orientale Province between June and November.[15][30]
2013–2016 Widespread:
 Liberia
 Sierra Leone
 Guinea
Limited and local:
 Nigeria
 Mali
 United States
 Senegal
 Spain
 United Kingdom
 Italy
EBOV 28,616[31] 11,310 70-71% (General) [32][33][34][note 2]
57-59% (Among hospitalized patients)[35]
This was the most severe Ebola outbreak recorded in regards to both the number of human cases and fatalities. It began in Guéckédou, Guinea, in December 2013 and spread abroad.[36][37][32]:pages 1481–95 Although the epidemic is no longer out of control, flare-ups of the disease have continued into 2016, and the WHO has warned that this may continue for some time.[38]
2014  Democratic Republic of the Congo EBOV 66[39] 49[39] 74% Occurred in Équateur province. Outbreak detected 24 August and, as of 28 October 2014, the WHO said that twenty days had passed since the last reported case was discharged and no new contacts were being followed.[39][40] Declared over on 15 November 2014.[41]

On 11 May 2017, the Ministry of Public Health for the Democratic Republic of the Congo notified the WHO of an Ebola outbreak in the Likati health zone (LHZ) in Bas-Uele province, which is in the northern part of the country. The suspected infections have been reported from Nambwa, Mouma, and Ngay. The LHZ borders the Central African Republic, making this outbreak a moderate risk to the region.[63]

Notes

  1. 1 2 In accordance with the sovereignty at the time.
  2. The mortality rate (death/case ratio) recorded in Liberia up to 26 August 2014 was 70 percent.[33] However, the general estimated case fatality rate (70.8 percent) for this ongoing epidemic differs from the ratio of the number of deaths divided by that of cases due to the estimation method used. Current infections have not run their course, and the estimate may be poor if reporting is biased towards severe cases.
  3. The Centers for Disease Control chronology notes this infection as "Sudan virus", whereas the 1977 British Medical Journal (BMJ) article refers to it as "Ebola virus". In 1977, there was No a distinction between different ebolaviruses. The BMJ article notes only that the patient received "convalescent serum from the Sudan" following similar serum from Zaire.
  4. 1 2 3 All cases were asymptomatic.
  5. The case was repatriated to Switzerland for medical treatment.[51]
