Is the breathing equipment really effective?

Filamentous 970 nm long (click here) for Ebolavirus. Diameter is about 80nm. Negative-stranded RNA linear genome, about 18-19 kb in size. Encodes for seven proteins.

Except for the journalist and Mr. Duncan the people infected are health care workers.

We are seeing more and more health care workers contracting this virus. Are we keeping up with any and all changes this virus might be undergoing.

The standard is Aspergillus:

Genome sizes for sequenced species of Aspergillus range from about 29.3 Mb for A. fumigatus to 37.1 Mb for A. oryzae, while the numbers of predicted genes vary from about 9926 for A. fumigatus to about 12,071 for A. oryzae. The genome size of an enzyme-producing strain of A. niger is of intermediate size at 33.9 Mb.

Aspergillus spores are very very small - 2-3 microns (millionth of a meter).


1 nanometer = 0.001 microns

I can't help believe that anything less than a self-contained breathing apparatus is best. Other masks regardless of their filtration capacity become moist and can compromise health care workers.

It might be extreme, but, when a health care worker is performing tasks the equipment can also become a problem. 

There is also the issue of a patient in an ICU unit and the preparedness to respond to a patient's need or request. Putting on isolation equipment has to be a higher priority than getting to the patient.

There has to be 'error' built into the isolation equipment. The workers should be protected 150% and not just 100%. Human error is a fact and this virus is unforgiving.

We have to do better to protect health care workers and in West Africa.

Duct tape? Really?

This picture proves the depth of the medical professional in caring for patients. The gloves look more like something worn to wash dishes than provide health care. 

Part of the strategy to ending the virus is ending the infection in West Africa. This type of isolation equipment will eventually fail.
