BCX4430 (Immucillin-A) is an antiviral drug, an adenosine analog (a type of nucleoside analog).
 It is developed by BioCryst Pharmaceuticals with funding from NIAID, originally intended as a treatment for Hepatitis C, but subsequently developed as a potential treatment for deadly filovirus infections such as Ebola virus disease and Marburg virus disease.
 It also shows broad-spectrum antiviral effectiveness against a range of other RNA virus families, including bunyaviruses, arenaviruses, paramyxoviruses, coronaviruses and flaviviruses.
 BCX4430 has been demonstrated to protect against both Ebola and Marburg viruses in both rodents and monkeys, even when administered up to 48 hours after infection, and development for use in humans is being fast-tracked due to concerns about the lack of treatment options for the 2013-2016 Ebola virus epidemic in West Africa.
 BCX4430 also showed efficacy against Zika virus in a mouse model, though there are no plans for human trials at this stage.
An Ebola virus epidemic in Sierra Leone occurred in 2014, along with the neighbouring countries of Guinea and Liberia.
 On March 18, 2014 Guinean health officials announce the outbreak of a mysterious hemorrhagic fever "which strikes like lightning."
 It was identified as Ebola virus disease and spread to Sierra Leone by May 2014.
 The disease is thought to have originated when a child in a bat-hunting family contracted the disease in Guinea in December 2013.
 Consumption of African bushmeat, including rats, bats, and monkeys, is commonplace in Sierra Leone and West Africa in general.
cAd3-ZEBOV (also known as the NIAID/GSK Ebola vaccine or cAd3-EBO Z) is an experimental vaccine for two ebolaviruses, Ebola virus and Sudan virus, developed by scientists at GlaxoSmithKline (GSK) and tested by National Institute of Allergy and Infectious Disease (NIAID).
 This vaccine is derived from a chimpanzee adenovirus, Chimp Adenovirus type 3 (ChAd3), genetically engineered to express glycoproteins from the Zaire and Sudan species of ebolavirus to provoke an immune response against them.
 Simultaneous phase 1 trials of this vaccine commenced in September 2014, being administered to volunteers in Oxford and Bethesda.
 During October the vaccine is being administered to a further group of volunteers in Mali.
 If this phase is completed successfully, the vaccine will be fast tracked for use in the Ebola virus epidemic in West Africa.
 In preparation for this, GSK is preparing a stockpile of 10,000 doses.
Ebola virus disease in Nigeria occurred in 2014, the 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 countries in Central Africa.
 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.
An epidemic of Ebola virus disease 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.
 The epidemic, which began with the death of a two-year-old boy in 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 minor outbreaks occurring in Senegal, Nigeria, and Mali.
 In 2015, Guinea was declared free of Ebola transmission by the U.N. World Health Organization.
Band Aid 30 is the 2014 incarnation of the charity supergroup Band Aid.
 The group was announced on 10 November 2014 by Bob Geldof and Midge Ure, with Geldof stating that he took the step after the United Nations had contacted him, saying help was urgently needed to prevent the 2014 Ebola crisis in Western Africa spreading throughout the world.
 As in previous incarnations, the group covered the track "Do They Know It's Christmas?
", written in 1984 by Geldof and Ure, this time to raise money towards the Ebola crisis in Western Africa.
 The track has re-tweaked lyrics to reflect the current Ebola virus epidemic in West Africa with all proceeds going towards battling what Geldof described as a "particularly pernicious illness because it renders humans untouchable and that is sickening".
"Do They Know It's Christmas?"
 is a song written in 1984 by Bob Geldof and Midge Ure in reaction to television reports of the 1983–85 famine in Ethiopia.
 It was first recorded in a single day on 25 November 1984 by Band Aid, a supergroup put together by Geldof and Ure and consisting mainly of the biggest British and Irish musical acts at the time.
 The single was released in the United Kingdom on 3 December 1984 and aided by considerable publicity it entered the UK Singles Chart at number one and stayed there for five weeks, becoming the Christmas number one of 1984.
 The record became the fastest selling single in UK chart history, selling a million copies in the first week alone and passing 3 million on the last day of 1984, on the way to becoming the biggest selling single of all time in the UK.
 It held this title until 1997 when it was overtaken by Elton John's "Candle in the Wind 1997", released in tribute to Princess Diana following her death.
 The original version of "Do They Know It's Christmas?"
 has sold 3.8 million copies in the UK to date.
Ebola virus ( ; EBOV, formerly designated Zaire ebolavirus) is one of five known viruses within the genus "Ebolavirus".
 Four of the five known ebolaviruses, including EBOV, cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD).
 Ebola virus has caused the majority of human deaths from EVD, and is the cause of the 2013–2015 Ebola virus epidemic in West Africa, which has resulted in at least suspected cases and confirmed deaths.
In 2014, Ebola virus disease in Spain occurred due to two patients with cases of the disease contracted during the Ebola virus epidemic in West Africa; they were medically evacuated.
 A failure in infection control in the treatment of the second patient led to an isolated infection of Ebola virus disease in a health worker in Spain itself.
 The health worker survived her Ebola infection, and has since been declared infection-free.
The Ouse to Ouse Tock (House to House Talk) was a three-day quarantine in Sierra Leone from 19 September 2014 to 21 September 2014.
 It was part of an effort to combat the Ebola virus epidemic in Sierra Leone, part of the Ebola virus epidemic in West Africa.
 One of the goals was to cut down on transmission within families, so individual homes were visited.
 There was concern that some families were harboring Ebola cases and that there was a lack of knowledge about the disease.

Question: Alongside Bob Geldof, who co-wrote the 1984 song written in reaction to television reports of the 1983–85 famine in Ethiopia, which was re-released in 2014 with re-tweaked lyrics to reflect the Ebola virus epidemic in West Africa?
Answer: Midge Ure
