EBOLA Time-line Recap

We've traced coverage of the outbreak, and tracked its progress in the timeline below, as reported by the C.D.C. and the W.H.O.:

January 2014: Believed to be the month of origin of this outbreak, when the virus infected its first host and incubated.
February 2014: First cases of Ebola are reported in Guinea.
March 25, 2014: After suspected cases arise throughout its rural districts of Guekedou, Macenta, Nzerekore, and Kissidougou, the government of Guinea officially reports an outbreak of Ebola. Suspected cases are also reported in Liberia and Sierra Leone. Guinea enlists Doctors without Borders to establish Ebola treatment centers throughout the affected regions.
March 27, 2014: The virus reaches Guinea's capital of Conakry, the most populated—the city is home to 2 million people—site the outbreak has affected so far. The Bernhard-Nocht Institute of Tropical Medicine in Hamburg, Germany, and the Institut Pasteur in Dakar, Senegal, join the efforts of Institut Pasteur in Lyon, France, testing samples. Researchers confirm the virus is a strain of Ebola that had originally been discovered in Zaire (now Democratic Republic of Congo) in 1976.
March 29, 2014: The virus is confirmed to have reached Liberia.
March 31, 2014: More international organizations arrive in the region: The International Red Cross, Pentecostal Mission Unlimited, and Samaritan's Purse set up to spread awareness campaigns and distribute protective equipment. The W.H.O. leads the international response, and the C.D.C. sends a five-person team to help.
April 1, 2014: Guinea reports its first case of Ebola in the Djingaraye district, much farther north compared to the previously reported districts, indicating a new outbreak origin point.
April 7, 2014: The number of fatalities crosses 100 people, with 95 deaths in Guinea, and 7 in Liberia. Some of the cases include infected health workers.
April 30, 2014: The number of fatalities crosses 150 people, with 146 deaths in Guinea (16 of those being health care workers), and 9 deaths in Liberia.
May 27, 2014: The number of fatalities reaches 200 people, with 186 deaths in Guinea, 9 in Liberia, and 5 in Sierra Leone—the first deaths reported in the country. The WHO and CDC confirm that the country's Kailahun district is the outbreak's hot spot, while laboratory testing begins in the city of Kenema.
May 28, 2014: For the first time, cases are reported from the counties of Boffa, Boke, and Dubreka in western Guinea, covering a new region of the country.
June 2, 2014: The first suspect case is reported in Liberia since April 9, and investigations begin to contain yet another outbreak point. The stretch of time between the reports in Liberia exceeded the 21 days for Ebola to incubate.
June 18, 2014: The number of fatalities crosses 300 people, with 264 deaths in Guinea, 24 in Liberia, and 49 in Sierra Leone.
July 8, 2014: The number of fatalities crosses 500 people, with 307 deaths in Guinea, 84 in Liberia, and 127 in Sierra Leone.
July 18, 2014: The number of suspected cases crosses 1000, with 1048 people reached.
July 22, 2014: A Liberian official dies after landing in Lagos, Nigeria, the most populous city so far, with 21 million inhabitants. The death initiates a series of red alert responses from the country (now the fourth African country to include a case of Ebola), which increases surveillance at all ports of entry. Follow-up work begins in Togo, where the official's plane had also landed on its way to Nigeria.
July 23, 2014: The number of fatalities reaches 672 people, with 319 deaths in Guinea, 129 deaths in Liberia, and 224 deaths in Sierra Leone. In Sierra Leone, the leading doctor fighting the outbreak is reported to have been infected as well, after having treated more than 100 victims in the country.
July 25, 2014: Street protests occur in Kenema, Sierra Leone, resulting in police firing tear gas into the crowds that threatened the city's hospital. The protestors had planned to burn down the hospital and eradicate the virus—an approach that would not at all have prevented further outbreaks. Instead, the W.H.O. reports Guinea experiencing a surge in cases indicates further undetected chains of transmission.
July 26, 2014: The first death occurs in Sierra Leone's capital city of Freetown, and a leading doctor in Liberia succumbs to the virus.
July 27, 2014: The first Americans are infected in the outbreak. Both are health workers.
July 28, 2014: Nigeria suspends flights to Liberia and Sierra Leone for its largest air carrier, Arik Air.
July 29, 2014: Nigeria's Asky Air follows Arik and suspends flights to Liberia and Sierra Leone. The airline will screen passengers flying out of Guinea. Meanwhile, Liberia has suspended all soccer-related activities, as sweat is a bodily fluid that could allow for Ebola transmission. And according to the BBC, Dr. Sheik Umar Khan, the leading Ebola doctor in Sierra Leone who contracted the virus on July 23rd, has died.

You should be able to go forward from here.

This is exceedingly helpful. In a few weeks I will be teaching in a course "Control of Infectious Diseases" for health professionals. Many of them are from developing countries. I will cite this website.
