Ebola virus epidemic in Guinea

An ongoing epidemic of Ebola virus disease (commonly known as "Ebola") in Guinea represents the first ever outbreak of Ebola in a West African country. Previous outbreaks have been confined to several countries in Sub-Saharan Africa.^[2] The epidemic, which began with the death of a 2-year-old boy in December 2013, is now part of a larger Ebola virus epidemic in West Africa which has spread through Guinea and the neighboring countries of Liberia and Sierra Leone, with smaller outbreaks occurring in Senegal, Nigeria, and Mali. In late December 2015, Guinea was declared free of Ebola transmission by the U.N. World Health Organization.^[3]

Researchers believe that the index case was Emile Ouamouno, a 2-year-old boy who lived in the village of Meliandou, Guéckédou located in the Nzérékoré Region of Guinea. Researchers from the Robert Koch Institute in Berlin believe the child contracted the virus while playing near a tree that was a roosting place for free-tail bats infected with the virus. Dr Fabian Leendertz, an epidemiologist who was part of the investigative team, said Ebola virus is transmitted to humans either through contact with larger wildlife (gorillas, monkeys), or by direct contact with bats. The child, later identified as Emile Ouamouno, fell ill on 2 December and died 6 December 2013.^[4][5] His sister fell ill next, followed by his mother and grandmother.^[6][7] It is believed the Ebola virus was then spread to the villages of Dandou Pombo and Dawa, both in Guéckédou, by the midwife who attended them. From Dawa village the virus spread to Guéckédou Baladou District and Guéckédou Farako District, and on to Macenta and Kissidougou.^[6][7]

Although Ebola represents a major public health issue in sub-Saharan Africa, no cases had ever been reported in West Africa and the early cases were diagnosed as other diseases more common to the area such as Lassa fever, another hemorrhagic fever similar to Ebola. Thus, it wasn't until March 2014 that the outbreak was recognized as Ebola. The Ministry of Health of Guinea notified the World Health Organization (WHO), and on 23 March the WHO announced an outbreak of Ebola virus disease in Guinea with a total of 49 cases as of that date.^{[8][9][10][11]} By late May, the outbreak had spread to Conakry, Guinea's capital, a city of about two million inhabitants.^[12]

Containment efforts

Quarantines and travel restrictions

In March, Guinea's President Alpha Conde declared a national health emergency due to the outbreak. He stated efforts to control the spread of the Ebola virus would include forbidding Ebola patients from leaving their homes, border control, travel restrictions, and hospitalization for individuals suspected to be infected until cleared by laboratory results. He also banned the transporting of the dead between towns.^[13]

Good disease tracing is important to prevent the outbreak from spreading. Previous Ebola outbreaks have occurred in remote areas making containment easier; the current outbreak struck in an area that lies at the centre of both a highly-mobile and densely populated region which has made tracking more difficult: "This time, the virus is traveling effortlessly across borders by plane, car and foot, shifting from forests to cities and springing up in clusters far from any previously known infections. Border closures, flight bans and mass quarantines have been ineffective." Peter Piot, who co-discovered Ebola, said Ebola "isn't striking in a 'linear fashion' this time. It's hopping around, especially in Liberia, Guinea and Sierra Leone".^[14][15]

Fear of healthcare workers and clinics

Containment has also been difficult due to fear of healthcare workers. Infected people and those that they have been in contact with have evaded surveillance, moving at will and hiding their illnesses while they infect others in turn. Entire villages, stricken by fear, have closed themselves off, giving the disease an opportunity to strike in another area. It has been reported that in some areas it is believed that health workers are purposely spreading the disease to the people, while others believe that the disease does not exist. Riots broke out in the regional capital, Nzérékoré, when rumors were spread that people were being contaminated when health workers were spraying a market area to decontaminate it.^[16]

In May, the number of Ebola cases appeared to be decreasing and Médecins Sans Frontières (MSF) closed a treatment facility in the Macenta region because the outbreak of Ebola there appeared to have been resolved. At the time it was thought that the new cases were caused by people returning from Liberia or from Sierra Leone, however it was later suggested that villagers had become fearful and were hiding cases rather than reporting them. Seeing workers wearing the required protection outfits worn by health workers and taking those suspected of having Ebola or of being contacts to the treatment center (perhaps never to be seen again), refusing the usual burial rituals when a patient died, and other actions taken by the unfamiliar individuals that had come to their remote areas, had led to rumors of organ harvesting and government and tribal plots. According to a September news report, "Many Guineans say local and foreign healthcare workers are part of a conspiracy which either deliberately introduced the outbreak, or invented it as a means of luring Africans to clinics to harvest their blood and organs."^[17]As described in another news article, "The health workers don’t look like any people you’ve ever seen. They perform stiffly and slowly, and then they disappear into the tent where your mother or brother may be, and everything that happens inside is left to your imagination. Villagers began to whisper to one another—They’re harvesting our organs; they’re taking our limbs".^[18] Moreover, due to fear, many people are avoiding hospital treatment for any ailment and are self-treating with over the counter drugs from a pharmacy.^[17]

On 18 September, eight members of a health care team were murdered by local villagers in the town of Womey near Nzérékoré.^[19] The team consisted of Guinean health and government officials accompanied by journalists, who had been distributing Ebola information and doing disinfection work. They were attacked with machetes and clubs, and their bodies were found in a septic tank. The dead included three journalists and four volunteers.^[20][21][22]

Outbreak progression

October 2014

The governor of Conakry, Soriba Sorel Camara, prohibited all cultural events for the holiday of Tabaski in a decree of 2 October 2014.^[23][24]

In the WHO Situation Report of 8 October, it was reported, that the transmission of Ebola was persistently high with approximately 100 new confirmed cases in the first week of October. The first cases were reported in the district of Lola.^[25] Médecins Sans Frontières reported a massive spike in the number of new cases in the capital city of Conakry. One facility admitted 22 patients in a single day (October 6), 18 of them coming from Coyah region, 50 kilometres (31 miles) east of Conakry.^[26]

On 19 October, Guinea reported two new districts with Ebola cases. The Kankan district, on the border with the Côte d'Ivoire and a major trade route to Mali, confirmed one case. Kankan also borders the district of Kerouane in this country, one of the areas with the most intense virus transmissions. The Faranah district to the north of the border area of Koinadugu in Sierra Leone also reported a confirmed case. Koinadugu was one of the last Ebola-free regions in that country. According to a WHO report, this new development highlights the need for increased surveillance of cross border traffic in an effort to contain the disease to the three most affected countries.^[27]

On 23 October, Saccoba Keita, the head of Guinea's Ebola mission, announced the government has started compensating the families of health care workers who died after contracting the virus. At that time, 42 health care workers had died, including doctors, nurses, drivers, and porters. The compensation totals $10,000 (£6,200) and is to be paid as a lump sum.^[28]

November 2014

In mid-November, the WHO reported that while intense transmission persists and cases and deaths continue to be under-reported, there is some evidence that case incidence is no longer increasing nationally in Guinea. They report that case numbers in some districts have been fluctuating, but they remain consistently high. New case numbers have been declining in the outbreak’s epicentre of Gueckedou, but transmission continues to be high in Macenta. Of a total of 34 districts in Guinea, 10 remain unaffected by Ebola, contrasting with Liberia and Sierra Leone, where every district has been affected.^[29]

On 20 November, the local Red Cross in Kankan Prefecture sent blood samples via a courier when the taxi he was traveling in was stopped by robbers. The bandits made off with the cooler bag containing the blood samples. The Guinea authorities made a public appeal for the return of the blood samples. The robbery occurred near the town of Kissidougou.^[30]

December 2014

On 14 December the WHO stated that 17 districts reported new confirmed or suspected cases in this week. Guinea reported 2,416 cases with 1,525 deaths on this date. Only 10 out of the 34 districts have not reported cases. Conakry reported 18 new cases in this week. The northern district of Siguiri is of particular concern, as it borders Mali and reported 4 new probable cases.^[31]

Free of Ebola transmission

The country was declared free of Ebola transmission on 29 December, 42 days after the last Ebola patient tested negative for a second time.^[32] Guinea was subsequently in a 90-day period of heightened surveillance according to the U.N. World Health Organization which also offered assistance^[33] - with funding from the agency's donors, UNICEF and its implementing partners - in improving Guinea's health care system.

Works derived from the Ebola crisis

• "White Ebola", a political song by Mr. Monrovia, AG Da Profit and Daddy Cool, centered on the general mistrust of foreigners.^[34]
• "Ebola in Town", a dance tune by a group of West African rappers, D-12, Shadow and Kuzzy Of 2 Kings, warns people of the dangers of the Ebola virus and explaining how to react.^[35][36]
• Senegalese rapper Xuman parodied Rihanna's "Umbrella" in "Ebola est là" (Ebola Is Here). The song's lyrics warn locals that, "The disease is among our neighbours, Liberians and Guineans."^[36][37]
• "Africa Stop Ebola", featuring contributions from Malian, Guinean, Ivorian, Congolese and Senegalese artists was recorded to raise awareness of Ebola and offers info on how people can protect themselves from the disease.^[38] The song is sung in several of the local languages.^[39]
• There are a number of Ebola-themed jokes circulating in West Africa.^[40]
