WHY EBOLA IS A REAL CONCERN
These are my thoughts, written down, simply so that I can reflect back on them as the Ebola crisis unfolds. While I have a few minutes, I figured I would jot down some notes, but make them public as well. In doing so, not only myself, but others can chime in with their own thoughts, and possibly we can collectively come up with a plan that would work to figure out the Ebola mystery. With the help of folks like +Jason Knight , +Jason A , +tracehd1 and others that are systematically using science and historical fact as the basis for their new hypothesis and theories, this system of "collective thought" or "crowd-sourcing" may allow us to assist those with Public Health responsibilities think of treatments or plans they might otherwise have missed.
Let's start with what we "know" :
1. Ebola and the filovirus class of pathogens that are related to the EVD / VHF diseases surrounding Ebola (collectively, I will simply use the term "Ebola" to cover the entire spectrum of the 4 known pathogenic viruses even though they are different strains... they all share similar properties of filoviruses as demonstrated by an article shared with me by +Jason Knight )... are all part of the Filovirus family. The CDC lists the Ebola virus as such:
Filoviruses belong to a virus family called Filoviridae and can cause severe hemorrhagic fever in humans and nonhuman primates. So far, only two members of this virus family have been identified: Marburgvirus and Ebolavirus. Five species of Ebolavirus have been identified: Taï Forest (formerly Ivory Coast), Sudan, Zaire, Reston and Bundibugyo. Ebola-Reston is the only known Filovirus that does not cause severe disease in humans; however, it can still be fatal in monkeys and it has been recently recovered from infected swine in South-east Asia.
2. Structurally, filovirus virions (complete viral particles) may appear in several shapes, a biological features called pleomorphism. These shapes include long, sometimes branched filaments, as well as shorter filaments shaped like a "6", a "U", or a circle. Viral filaments may measure up to 14,000 nanometers in length, have a uniform diameter of 80 nanometers, and are enveloped in a lipid (fatty) membrane. Each virion contains one molecule of single-stranded, negative-sense RNA. New viral particles are created by budding from the surface of their hosts' cells; however, filovirus replication strategies are not completely understood.
3. NATURAL HOST: It appears that Filoviruses are zoonotic, that is, transmitted to humans from ongoing life cycles in animals other than humans. Despite numerous attempts to locate the natural reservoir or reservoirs of Ebolavirus and Marburgvirus species, their origins were undetermined until recently when Marburgvirus and Ebolavirus were detected in fruit bats in Africa. Marburgvirus has been isolated in several occasions from Rousettus bats in Uganda.
4. TRANSMISSION: In an outbreak or isolated case among humans, just how the virus is transmitted from the natural reservoir to a human is unknown. Once a human is infected, however, person-to-person transmission is the means by which further infections occur. Specifically, transmission involves close personal contact between an infected individual or their body fluids, and another person. During recorded outbreaks of hemorrhagic fever caused by a Filovirus infection, persons who cared for (fed, washed, medicated) or worked very closely with infected individuals were especially at risk of becoming infected themselves. Nosocomial (hospital) transmission through contact with infected body fluids - via reuse of unsterilized syringes, needles, or other medical equipment contaminated with these fluids - has also been an important factor in the spread of disease. When close contact between uninfected and infected persons is minimized, the number of new Filovirus infections in humans usually declines. Although in the laboratory the viruses display some capability of infection through small-particle aerosols, airborne spread among humans has not been clearly demonstrated.
DEFINITIONS: Ebola, appears to be highly transmittable, more so than is being publicly announced. IT IS A BIOHAZARD LEVEL 4 PATHOGEN, meaning, it is at the HIGHEST RISK CATEGORY for viral pathogens. For a pathogen to be listed as a BSL4 (Bio-safety Risk Level 4), at least one of the criteria must be met:
1. Agents likely to cause serious or lethal human disease for
which preventive or therapeutic
interventions are not usually
available (high individual risk and
high community risk). (NATIONAL INSTITUTE OF HEALTH / NIH) or...
2. (High individual and community risk) A pathogen that usually causes serious human or animal disease and can be
readily transmitted from one individual to another, directly or indirectly. Effective
treatment and preventive measures are
not usually available. (WORLD HEALTH ORGANIZATION / WHO)
The problem, as it stands now, is that Ebola appears to be bypassing all known methods of transmission, bypassing the known host of the pathogen, appears to be a zoological pathogen that is being easily crossed over into people, appears to carry an extremely high virulent effect, appears to be associated with an extremely high mortality rate, appears to have no known treatment other than symptomatic support and appears to have MULTIPLE SITES OF ORIGIN, or, "Ground Zero."
Because the actual components of virology and mutation of viruses is a highly complex science, the dissection and microanalysis of the Ebola class virus, is better left to those who have a full working knowledge of the virus; it is not a simple science, and requires extensive hands-on experience as well as PhD level of study and practicum. However, even with that being the case, there is still plenty that laypersons as well as experienced medical / healthcare professionals (I will lump together in this group all persons licensed or certified to carry out healthcare tasks and diagnosis, including Certified Nursing Assistants, EMT's, First Responders, Licensed Practical / Vocational Nurses, Registered Nurses, Physicians (both MD & DO), as well as DMD's, DVM's, and Advanced Practice Nurses (Nurse Practitioners / NP's and Clinical Nurse Specialists / CNS's). To be included in this group, will also be Laboratory Professionals whose scope and practice is to deal with viruses and other pathogens that require any rating higher than BSL1 (BSL2 - BSL4).
PROBLEM STATEMENT: Ebola is a rapidly transmittable, highly pathogenic virus with a known vector but the epidemiology of the EVD appears to be crossing over species much more readily than expected, in a manner inconsistent with known transmission theories and producing a potential world-wide public health threat, for which there is no known cure (to date) and carries a high mortality rate.

Before we can proceed further, we need to establish the answers to some of the above unknown variable questions. If we, as a society, are unable to establish the answers to most of the above, then moving forward with the exercise if futile... therefore, experts with experience and/or knowledge of the above are encouraged to share your knowledge so that we can start to formulate a plan of action.
