  1. Coronavirus from SARS isolated in FRhK-4 cells. Thin section electron micrograph and negative stained virus particles SOURCE:Department of Microbiology, The University of Hong Kong and the Government Virus Unit, Department of Health, Hong Kong Susceptibility of Dutch Buildings to SARS transmission JEMH van Bronswijk, TU Eindhoven

  2. Survival of SARS Corona virus • -80°C in frozen liquid > 21 days • +4°C in liquid > 21 days • Room temperature:plastic surface > 2 days; urine > 24 hours; stool > 2 days; baby stool of pH 6-7: 3 hours; normal stool pf pH 8: 6 hours; diarrhea stool of pH 9: 4 days • +30-37°C > 1 hour • +37°C in liquid < 4 days • +56°C in liquid < 30 min survival (destruction of 10,000 units / 15 min) SOURCE: WHO collaborative multi-centre research project on Severe Acute Respiratory Syndrome (SARS) diagnosis; First data on stability and resistance of SARS coronavirus compiled by members of WHO laboratory network; May 4, 2003; http://www.who.int/csr/sars/survival_2003_05_04/en/index.html JEMH van Bronswijk, TU Eindhoven

  3. Disinfecting for SARS Corona virus • < 5 min Survival at Room Temperature • Liquid Acetone • Formaldehyde & Para formaldehyde 10% • Chlorox 10% • Ethanol 75% • Phenol 2% SOURCE: WHO collaborative multi-centre research project on Severe Acute Respiratory Syndrome (SARS) diagnosis; First data on stability and resistance of SARS coronavirus compiled by members of WHO laboratory network; May 4, 2003; http://www.who.int/csr/sars/survival_2003_05_04/en/index.html JEMH van Bronswijk, TU Eindhoven

  4. Susceptibility of Buildings(at +4°C > 21 days of survival; at room temperature 4 days survival) • Ventilation & Air-condition systems (recirculation, one-way valves, polluted humidification systems) • Liquid waste removal (toilet flushing, decontamination of toilet seat, leakage, sewer bleeding) • Cleanability of Finishing Materials & Toilets • Disinfections possibilities • Protection of Potable Water • 2nd quality Household Water JEMH van Bronswijk, TU Eindhoven
