  • #2: Centralized Quarantine worked!
  • #3: A good proportion are community cases: Testing, Testing, Testing
  • #4: A Multi-pronged Approach is needed (Large scale screening using symptoms (with/without testing kits), Increase testing capacity, physical distancing/home quarantine, Centralized quarantine for confirmed and suspected cases, symptomatic cases and close contacts (asymptomatic)
  • #5: Protect the Four Vulnerable Groups (healthcare workers, elderly, children, and those at home with confirmed or suspected cases)
  • #6: These Protection Strategies Worked! Full protection, stringent safety protocol, training.

Flattening the curve (Blue) to ensure those who need medical attention for COVID-19 can get it vs having no controls on the spread of the virus and having more persons requiring medical attention than the local health system can provide at the time. This should be examined for each location in terms of resources. Taken from
R is the transmission rate. This table is for illustrative purposes only, emphasizing the kinds of data that can help decision makers. It is part of Tomas Pueyo’s “Coronavirus: The Hammer and the Dance.

  • Dr. Charles Haas — Drexel University, WRF Academic Council (Moderator). Established taxonomy that COVID 19 refers
    to the disease, and SARS-CoV-2, 2019-nCoV and COVID-19 refers to the virus. The WHO guidance on safe management of drinking water and sanitation services applies to COVID-19 outbreak with no extra measures needed — disinfection works.
  • Jonathan Yoder — Water Preparedness and Response at the Centers for Disease Control and Prevention. Some useful links on disinfection were highlighted: and
  • Dr. Rasha Maal-Bared — EPCOR Water, Chair of the WEF Waterborne Infectious Disease Outbreak Control (WIDOC) Working Group of the Disinfection and Public Health Committee. COVID-19 is an enveloped virus, and is therefore most susceptible to environmental conditions and disinfection than a suite of other bacteria and viruses. Fecal-oral transmission is possible, but likelihood seems low. However, all surfaces contacted by wastewater should be disinfected.
  • Dr. Mark Sobsey — Gillings Schools of Global Public Health, University of North Carolina Chapel Hill and Dr. Lisa Casanova — Georgia State University. Previous studies on coronaviruses show that temperature and humidity influence survival on surfaces (less survival at 25oC vs 4oC, and 50% relative humidity vs 20% or 80%). In water, survival of surrogate coronaviruses can be days, and again this is lessened at 25oC vs 4oC. Solid waste with COVID-19 should be handled as Category B Medical Waste, however it was unclear how this applied to individual homes and sanitary worker exposure. Informative slides on appropriate disinfectants for water and surfaces, and emphasis on research gaps.
  • Dr. Kyle Bibby — University of Notre Dame. Evidence suggests that COVID-19 is found in feces, but uncertainties exist on survival rate in wastewater, and disinfection effectiveness of wastewater.
  • Dr. Dan Deere — Water Quality Specialist at Water Futures, Australia. Water and wastewater concerns from the industry/practitioners led to a global effort to share information with each other, and with the public to better handle unanticipated consequences (disposal of sanitizers and wet wipes down toilets, especially as toilet paper ran out in places). Questions were raised on safety of wastewater operators during the webinar, and personal protective equipment was stressed, as well as expecting plant operations with minimum staff. Presentation shared good resources for the water and wastewater sector.
