The highly respected Center for Infectious Disease Research and Policy (CIDRAP) at the University of Minnesota just advised the U.S. Centers for Disease Control (CDC) and World Health Organization (WHO) that there is scientific and epidemiologic evidence that Ebola virus has the potential to be transmitted via infectious aerosol particles, including exhaled breath.

CIDRAP is warning that surgical facemasks do not prevent transmission of Ebola, and healthcare professionals (HCP) must immediately be outfitted with full-hooded protective gear and powered air-purifying respirators.
CIDRAP since 2001 has been a global leader in addressing public health preparedness regarding emerging infectious diseases and bio-security responses. CIDRAPs opinion on Ebola virus is there are No proven pre- or post-exposure treatment modalities; A high case-fatality rate; and Unclear modes of transmission.
