I’ve got two WHO PCs to catch up on, but wanted to make a few (scattered) notes / thinking out loud:
What is the
latest data on how much surface transmission is contributing to community spread.
Separate thought:
I’m searching for specific report re: CDC & water / came across this and noticing / BBM:
Coronavirus Disease 2019 (COVID-19)
“The risk of transmission of COVID-19 from the feces of an infected person is also unknown. However, the risk is expected to be low based on data from previous outbreaks of related coronaviruses, such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).
There have been no reports of fecal-oral transmission of COVID-19 to date.”
Okay wait a minute. Read that last sentence again. If that’s true, then how come we had pages of discussions about this.
Checking article date

Additionally on this subject, remember the workers in Wuhan wore diapers, didn’t eat/drink so they wouldn’t have to go to the bathroom bc they have to change out their suits/PPE every time and they were preserving PPE..
I thought there was something to due to fecal transmission about that - need to check that again, maybe not but I think I’m recalling a video moo.

“Can the COVID-19 virus spread through sewerage systems?
CDC is reviewing all data on COVID-19 transmission as information becomes available. At this time, the risk of transmission of the virus that causes COVID-19 through sewerage systems is thought to be low. Although transmission of COVID-19 through sewage may be possible, there is no evidence to date that this has occurred. This guidance will be updated as necessary as new evidence is assessed.
SARS, a similar coronavirus, has been detected in untreated sewage for up to 2 to 14 days. In the 2003 SARS outbreak, there was documented transmission associated with sewage aerosols. Data suggest that standard municipal wastewater system chlorination practices may be sufficient to inactivate coronaviruses, as long as utilities monitor free available chlorine during treatment to ensure it has not been depleted.
Wastewater and sewage workers should use standard practices, practice basic hygiene precautions, and wear personal protective equipment (
PPE) as prescribed for current work tasks.”
Hmmm— They sure disinfected the heck out of the sewers in Wuhan and I got the impression back then it was more than precautionary...need to go back to look at Wuhan/disinfecting sewer-related reports.
•we also know the Hong Kong SARS cluster happened through that “pipe problem” that infected many in that residential building, hence the “APVLD” discussions - (Aerosol Plumes of Virus- Laden Diarrhea”)
