Dr. Jane Orient, the executive director of the Association of American Physicians and Surgeons, told CCTV recently that the disease is very infectious.
Dr. Orient says the Ebola virus can be viable in an aerosol after ninety minutes.
The health care workers must have their own air supply.
Dr. Kent Brantley, the now cured Samaritan’s Purse doctor, initially tested negative for Ebola. Nurse Nancy Writebol (the now cured Samaritan’s Purse nurse) tested positive for Malaria initially!
The two later came down with Ebola.
The disease is very infectious. One particle of Ebola in the bloodstream can cause a fatal infection.
The New Yorker reported:
Since there is no vaccine against or cure for the disease caused by Ebola virus, the only way to stop it is to break the chains of infection. Health workers must identify people who are infected and isolate them, then monitor everybody with whom those people have come in contact, to make sure the virus doesn’t jump to somebody else and start a new chain. Doctors and other health workers in West Africa have lost track of the chains. Too many people are sick, and more than two hundred medical workers have died.
The virus is extremely infectious. Experiments suggest that if one particle of Ebola enters a person’s bloodstream it can cause a fatal infection.
All the drugs, vaccines, and diagnostic tests for Ebola depend critically on the virus’s genetic code. The researchers knew that the code was changing.
Since Ebola makes errors as it replicates, each genome was like a hand-copied text, and detectable differences would emerge among the genomes; there isn’t just one “strain” of the virus.
Then one of the nurses got sick with Ebola and died. She hadn’t even been working in the Ebola ward. The virus particles were invisible, and there were astronomical numbers of them in the wards; they were all over the floor and all over the patients.
There are two distinct ways a virus can travel in the air. In what’s known as droplet infection, the virus can travel inside droplets of fluid released into the air when, for example, a person coughs. The droplets travel only a few feet and soon fall to the ground. The other way a virus can go into the air is through what is called airborne transmission. In this mode, the virus is carried aloft in tiny droplets that dry out, leaving dust motes, which can float long distances, can remain infective for hours or days, and can be inhaled into the lungs. Particles of measles virus can do this, and have been observed to travel half the length of an enclosed football stadium. Ebola may well be able to infect people through droplets, but there’s no evidence that it infects people by drying out or getting into the lungs on dust particles…A rule of thumb among Ebola experts is that, if you are not wearing biohazard gear, you should stand at least six feet away from an Ebola patient, as a precaution against flying droplets.
Meanwhile, at the ELWA hospital, two hundred miles to the south, a fifty-nine-year-old American health worker named Nancy Writebol got a fever. She tested positive for malaria and went to bed in her house, on the grounds of the hospital
“You guys make me a little bit nervous,” she typed, and she advised them to wear breathing masks outside the windows of the two patients.
Already, some of the mutations were making Ebola less visible to the tests for it.
