Exactly! Remember the fiasco with transfusions with tainted blood when Aids first made the mainstream. So many ways for exposure that are not prepared for in any way for something like this.

And the CDC is the ONLY place ebola tests are being done in the US. There is no highly-reliable cheap and quick test for Ebola right now, which is why the CDC does two different kinds of tests to make sure they have some level of confidence of the results from either test. Donated blood and plasma will not be tested for Ebola, period. Not for a long time. And just one virus cell can spread it. Jesus H, this truly is the "perfect storm" as one official put it. I didn't even think about the blood donation issue.
In the laboratory, infection through small-particle aerosols has been demonstrated in primates, and airborne spread among humans is strongly suspected, although it has not yet been conclusively demonstrated
"The Ebola virus strain responsible for Guinea's outbreak—now at 197 suspected or confirmed cases—is a new strain that has been sickening and killing people at least as far back as December, researchers reported yesterday.
The results of full genetic sequencing suggest that the outbreak in Guinea isn't related to others that have occurred elsewhere in Africa, according to an international team that published its findings online in the New England Journal of Medicine (NEJM)."
Diagnostic Assays
Viral RNA was extracted from 50 to 100 μl of undiluted plasma and 1:10 diluted plasma with the use of the QIAmp viral RNA kit (Qiagen)...
Clinical and Epidemiologic Analysis
The prominent clinical features of the EBOV infection in the confirmed cases were fever, severe diarrhea, and vomiting; hemorrhage was less frequent. The case fatality rate in the initial cases was 86% (12 of 14 patients with a known outcome died). Confirmed cases originated from hospitals in Guéckédou, Macenta, Nzérékoré, and Kissidougou prefectures (Figure 1). We performed an epidemiologic look-back investigation of the transmission chains by reviewing hospital documentations and interviews with affected families, patients with suspected disease, and inhabitants of villages in which cases occurred. According to the current state of the epidemiologic investigation, the suspected first case of the outbreak was a 2-year-old child who died in Meliandou in Guéckédou prefecture on December 6, 2013 (Figure 2). Patient S14, a health care worker from Guéckédou with suspected disease, seems to have triggered the spread of the virus to Macenta, Nzérékoré, and Kissidougou in February 2014. As the virus spread, 13 of the confirmed cases could be linked to four clusters: the Baladou district of Guéckédou, the Farako district of Guéckédou, Macenta, and Kissidougou. Eventually, all clusters were linked with several deaths in the villages of Meliandou and Dawa between December 2013 and March 2014.

I'm just gonna repost this again since kruphix missed it the first time around, and then the second time around, and he's on ATS again right now, so I want to make sure he gets the credible source he was asking for and doesn't overlook it.

It's never been proven, but it is strongly suspected by some experts:
In the laboratory, infection through small-particle aerosols has been demonstrated in primates, and airborne spread among humans is strongly suspected, although it has not yet been conclusively demonstrated
The study shows only one thing, and that is what it set out to show...that Ebola can be airborn transmission between pigs and primates. That is all it shows, you can not logically extrapolate anything else from those results.
Ebola then spreads in the community through human-to-human transmission, with infection resulting from direct contact (through broken skin or mucous membranes) with the blood, secretions, organs or other bodily fluids of infected people
Again, size and scope doesn't change the virus.

Define "other bodily fluids". Does saliva and mucous fall into the "other bodily fluids" category? If so, then like the Canadian experiment shows, a sneeze or cough could transmit the disease from person to person.
Study: Growing Guinea outbreak caused by new Ebola strain

Full-length gene sequencing revealed that the outbreak Ebola clade is separate from known viruses.
The Ebola virus strain responsible for Guinea's outbreak—now at 197 suspected or confirmed cases—is a new strain that has been sickening and killing people at least as far back as December, researchers reported yesterday.
The results of full genetic sequencing suggest that the outbreak in Guinea isn't related to others that have occurred elsewhere in Africa, according to an international team that published its findings online in the New England Journal of Medicine (NEJM).
The report is also the first detailed look at the epidemiologic features among the patients sickened in the early days of the outbreak in the forested region of Guinea, sketching out transmission chains that start with a 2-year-old girl who died in December.
Latest WHO numbers
As of yesterday, 197 suspected or confirmed Ebola virus disease (EVD) cases have been reported in Guinea, an increase of 29 since Apr 14, the World Health Organization (WHO) said in an update today. Fourteen more deaths were reported, raising the total to 122.
The WHO added that 101 cases have been lab confirmed. So far 47 of the cases, along with 16 of the deaths, have been in Conakry, the country's capital. Most of the others have been reported from the forested region in the southeastern part of the country where the outbreak began.
A team of 60 volunteers is helping the health ministry conduct contact tracing in Conakry, where 23 patients are still in isolation. Thirteen more case-patients are being treated in isolation units in Gueckedou (12) and Macenta (1).
In Liberia, 1 new EVD cases was reported, raising the total there to 27, while the number of deaths held steady at 13, according to the WHO statement. It said a suspected case reported yesterday from Nimba County has tested positive for Lassa fever. Two patients are still hospitalized, and health officials are still monitoring 33 contacts.
As part of response efforts in Liberia, the country's health ministry yesterday commissioned a new Ebola virus laboratory, a collaboration with Metabiota, a San Francisco–based infectious disease investigation group. Also, the health ministry and its global health partners visited two hospitals, where they conducted their first training in case management, triage, and infection control.
Meanwhile, Mali's health ministry reported yesterday that clinical samples from six suspected cases were negative for EVD. Tests on the samples were conducted at the WHO collaborating center at the Pasteur Institute in Senegal and at a mobile high-security lab at the University of Bamako.
In Sierra Leone, 12 suspected cases have been identified since Mar 19, but tests on clinical samples from 11 of them were negative for Ebola virus and other pathogens, according to the WHO. Health officials are following up on rumors of EVD cases and conducting active case finding.
So far no EVD cases have been detected in Sierra Leone, though two patients who died from the disease in Guinea earlier in the outbreak were brought back to Sierra Leone for burial.
Clinical features, genetic analysis
In the NEJM report, researchers said Guinea's health ministry first learned of clusters of a highly fatal mysterious disease that had been occurring in two cities in the forested region on Mar 10. The finding triggered an epidemiologic investigation by a European team from Doctors without Borders (Medecins Sans Frontieres) and prompted the collection of blood samples and clinical data from 20 patients, which were sent to biosafety level 4 labs for analysis in Lyon, France, and Hamburg, Germany.
Fifteen of the patients tested positive for the virus using conventional filovirus tests, and electron microscopy identified the Ebola virus in the serum of one patient. Researchers isolated the virus from cell culture in samples from five patients.
The team's genetic analysis found a high degree of similarity among 15 partial and 3 full-length sequences. Meanwhile, their full-length sequence analysis revealed that the Ebola clade is separate from other known viruses of its kind.
Clinical investigation found that the most common symptoms among confirmed case-patients were fever, severe diarrhea, and vomiting, but hemorrhage was less common. The case-fatality rate (CFR) of initial cases was 86% and for suspected cases was 71%, consistent with EVD.
Three fruit bat species that are thought to harbor Ebola viruses are found in large parts of West Africa, and the first outbreak in Guinea serves as a warning that the whole West African region is at risk for the disease, the team concluded.
Evidence of single introduction
The group's look back at the transmission chains found that the first suspected case was a 2-year-old girl from Gueckedou prefecture who died in early December. They also found that an infected health worker from the same part of Guinea appears to have spread the virus to Macenta, Nzerekore, and Kissidougou in February. As the outbreak grew, 13 of the confirmed cases could be linked to four clusters.
Researchers concluded that genetic evidence and epidemiologic links between the cases suggests a single introduction of the virus from animals to humans, which could have occurred in early December or before. They wrote that they suspect the virus was transmitted for months before clusters of cases in Gueckedou and Macenta signaled that an outbreak was under way.
Hemorrhage wasn't documented for most of the patients when blood samples were obtained, but could have occurred later, the team noted. They said, however, that the term "Ebola virus disease" was developed to emphasize that hemorrhage isn't seen in all patients. The researchers said the CFR is consistent with previous Ebola outbreaks.
That the Guinea Ebola strain is a separate clade suggests that the pathogen that sparked the outbreak evolved parallel with those seen in the Democratic Republic of Congo and Gabon and was not introduced into Guinea—the first West African nation to experience an Ebola outbreak—from those countries.

The official Ebola death toll jumped from 729 to 887 on Monday as Liberia confirmed dozens of new cases, but the doctor told us he believes the real number is at least 50 percent higher.

Eyes on Nigeria- tick, tick, tick.
In Nigeria, which recorded its first death from Ebola in late July, authorities in Lagos said eight people who came in contact with the deceased U.S. citizen Patrick Sawyer were showing signs of the deadly disease.
Nigerian authorities have been searching for and monitoring anyone who came into contact with Sawyer before and after he began showing symptoms. According to Health Minister Onyebuchi Chukwu, public health authorities are monitoring 70 people, have quarantined eight and say three are symptomatic.
Sawyer, a Liberian-American, stopped over in Ghana and Togo on his way from Liberia to Nigeria the day he fell ill. He was planning to return to his family in Minnesota in mid-August. His movement across West Africa sparked a search for 30,000 people he may have come into contact with.
The second confirmed case in Nigeria is a doctor who treated Patrick Sawyer, the Liberian-American man who died July 25 days after arriving in Nigeria from Liberia, said Nigerian Health Minister Onyebuchi Chukwu.
Three others who also treated Sawyer now show symptoms of Ebola and their test results are pending, he said. Authorities are trying to trace and quarantine others in Lagos, sub-Saharan Africa’s largest city of 21 million people.

I posted bits from that very article several pages ago, I doubt I was the first to do so, and I doubt you'll be the last. As far as fatalities go, the last number I saw was closing in on 900, though some experts believe that nearly 50% of the cases have gone unreported.
