Ebola 5: Ebola przenoszona przez powietrze

ver. 1.1.1

W końcu, po dziesiątkach zgonów heroicznych doktorów i pielęgniarzy, nie zapominając o administratorach szpitali, grabarzach, samych pacjentach czy ich sąsiadach, pojawia się coraz więcej głosów ze świata medycyny, że ebola może być przenoszona bez dotyku.

[Aktualizacja 25 października 2014]
Amerykańskie CDC potwierdza w oficjalnych zaleceniach, że ebola zakaża drogą kropelkową. Nareszcie! Ale czy tylu ludzi musiało wcześniej zginąć?
Patrz szczegóły tu




Czyli jest tak, jak pisałem wcześniej w wielu wpisach powołujących się na doświadczenia samych lekarzy, niektórych z nich już na tamtym świecie.

Pomińmy tu kwesię terminologii: czy to droga kropelkowa, czy areozolowa - ważne jest, co z tym zrobić. Otóż niewiele.

Oto cytaty:
Dr. Michael V. Callahan, an infectious disease specialist at Massachusetts General Hospital who has worked in Africa during Ebola outbreaks, does not think it is wrong for hospitals to opt for more protective equipment.
The minimal precautions recommended by the C.D.C. “led to the infection of my nurses and physician co-workers who came in contact with body fluids,” Dr. Callahan said. “I understand the desire to maintain absolute protection in U.S. hospitals.”

Dr. Fairless is considering buying his own air-purifying respirator to pair with a head-to-toe coverall. “I am not comfortable going to see an Ebola patient wearing a paper mask that doesn’t cover my entire face,” he said.

Furthermore, it’s still unclear how common indirect transmission between species is in the real world. It could explain why some Philippine pig farmers were infected with Reston Ebola even though they were not involved in slaughtering the swine, and had not come into contact with contaminated tissues, Kobinger noted.

Currently the CDC advises health care workers to use goggles and simple face masks for respiratory and eye protection, and a fitted N-95 mask during aerosol-generating medical procedures. Since so many doctors and nurses are dying in West Africa, it is clear that this level of protection is inadequate. Full face respirators with P-100 replacement filters would provide greater airway and eye protection, and I believe this would save the lives of many doctors, nurses and others who come into close contact with, or in proximity to, Ebola victims.

It is apparent that the primary mode of person to person Ebola transmission is through direct contact with the body or body fluids of Ebola victims, but it is unwise to ignore the airborne mode.

What do we know about Ebola viral disease to guide us in this decision?

  • The virus is transmitted via multiple routes: direct or indirect (fomite) contact with blood and body fluids (including urine, stool, vomitus, sweat, tears, semen, breast milk, and saliva), droplet, and fecal-oral. Airborne transmission is also possible if aerosolization occurs.
  • Healthcare workers are a major risk group for infection.
  • The disease manifestations drive transmission (bleeding, vomiting, diarrhea), leading to environmental contamination and contamination of HCW clothing, unprotected skin and mucosal surfaces. Simulated vomiting studies have shown that droplets can travel over 10 feet. The virus can remain infectious 1-2 days outside the human body.
  • Healthcare workers have become infected despite use of maximal barrier precautions.

"This includes isolation of the patient in a specially equipped negative pressure room and the use of personal protective equipment by trained staff, coordinated with infectious disease specialists."


“Even though the CDC and the medical field says Ebola’s not contagious until people are showing symptoms, we’re still afraid. Even me.”

Do sierpnia 2014 CDC zalecała pracownikom medycznym uważać na ... "zakażone powietrze":

[...] all persons, [...] who have the potential for exposure to patients and/or to infectious materials, including body substances, contaminated medical supplies and equipment, contaminated environmental surfaces, or contaminated air.

Porównajcie te warunki z powyższymi zachęcającymi a fałszywymi materiałami propagandowymi typu "niezabezpieczony lekarz wita Was z uśmiechem na progu"...

Senatorowie liberyjscy się "oburzyli" na prezydenta Sirleaf, i chcą... zlecić opiekę nad ebolą komuś z zagranicy. Na przykład MSF:
The Senators further argued that despite their initial approval of US$5 million and later US$15 Million, there are still cries for more funding, and that the situation in the counties is getting worse day by day.
Those who expressed discontent over the handling of the Ebola crisis suggested that the situation be turned over to groups like the Médicins San Frontiers and other international health-related organizations, which have experience from past outbreaks.

A Ugandian Ebola expert doctor Atai Omoruoto says the Ebola Virus Disease (EVD) in Liberia is very deceptive. She said the disease is deceptive due to the manner in which it kills people, especially those who are healthy instantly.

“From what I have observed since I came here (Liberia), is that this ebola disease is very deceptive because it kills people who are healthy instantly when they come in direct contact with it; you could be healthy and working and could just drop and die,” Dr.  Omoruoto said.

Wirus ebola (inny niż Zaire) przechodzi między POKOJAMI:
The investigators documented a high likelihood of aerosol transmission outside a controlled laboratory setting, because the virus appeared to pass between rooms to infect susceptible monkeys

Epidemiologists and virus experts believe the original case in that instance to have been a woman who went to a market in Guinea and then returned, unwell, to her home village in neighbouring northern Liberia.
The woman's sister cared for her, and in doing so contracted the Ebola virus herself before her sibling died of the haemorrhagic fever it causes.
Feeling unwell and fearing a similar fate, the sister wanted to see her husband - an internal migrant worker then employed on the other side of Liberia at the Firestone rubber plantation.
She took a communal taxi via Liberia's capital Monrovia, exposing five other people to the virus who later contracted and died of the Ebola. In Monrovia, she switched to a motorcycle, riding pillion with a young man who agreed to take her to the plantation and whom health authorities were subsequently desperate to trace.

Przypomina mi się stara "reklama" eboli:

Co jeszcze ciekawego?

Prawie wszystkie rozsądne linie zawiesiły loty do Liberii, wbrew zaleceniom WHO:

Dwindling Flights To And From Liberia
Arik Air-- flights suspended
ASKY-- flights suspended
Kenya Airways--flights suspended
Delta---last flight 8/31/14
British Airways--flights suspended
Air Côte d'Ivoire --flights suspended
Air Mali--flights suspended
Gambia Bird-/flights suspended
Air France--stopped flights before Ebola crisis

Powoli zamykają same lotnisko.

To samo się dzieje ze statkami i innymi środkami transportu.
Na granicy wojsko strzela do osób chcących ją przekroczyć. 
Liberia i kilka innych regionów przekształcają się w państwa-lazarety...
