Evening Ebola Update, Thurs, 2/19: EBOV decreases life expectancy 1-5 years in S.L. and Liberia/Airborne transmission possible   Leave a comment

2/19/15

Dear Colleagues:

l.  PLoS Currents Outbreaks has posted an article by Helleringer, et. al. from the Bloomberg School of Public Health, Johns Hopkins University re: the direct effect of the EBOV epidemic on life-expectancy in Sierra Leone, Liberia, and Guinea.  The authors determined life-expectancy using life-tables in each country and postulating several different scenarios; e.g., high or low number of EBOV cases, high or low non-reporting of EBOV cases.  The authors found that the EBOV epidemic decreased life-expectancy from 1-5 years in Sierra Leone and Liberia, but only 1 year in Guinea.  The authors note that non-direct effects of the EBOV epidemic; e.g., decrease in non-EBOV health care due to the demands of the EBOV epidemic, have decreased life-expectancy further.  See:  http://currents.plos.org/outbreaks/article/assessing-the-direct-effects-of-the-ebola-outbreak-on-life-expectancy-in-liberia-sierra-leone-and-guinea/

2.  Washington Post reports that Osterholm, et. al. (including Professor Kobinger) from the University of Minnesota and elsewhere have published on-line at mBio an article that says airborne transmission of EBOV is possible but very unlikely.  The authors have found EBOV viral particles on facemasks of HCW caring for EBOV patients.  EBOV is larger than most airborne viral infectious particles (8x the size of ‘flu’ virus, 4x the size of chickenpox virus, and 2x the size of TB.  See the Washington Post article at: http://www.washingtonpost.com/news/to-your-health/wp/2015/02/19/limited-airborne-transmission-of-ebola-is-likely-new-study-says/   The Osterholm article in mBio is found at: http://mbio.asm.org/content/6/2/e00137-15.full
