Novel coronavirus pneumonia deaths were more than 900 thousand cases in the United States on 4 th. How serious is the epidemic in the United States? The latest national wastewater sample test results are enough to reflect.
In order to understand the extent of the spread of COVID-19 in the United States, the CDC, from 15 days in from January 17th to 31st, asked more than 400 wastewater monitoring stations across the country to conduct daily COVID-19 monitoring of local public wastewater systems.
On 4 July, the CDC released the monitoring data at the press briefing. The results showed that during the 15 days, the waste water monitor system collected more than 34000 samples representing about 53 million Americans, of which 98% of the monitoring stations detected COVID-19 in all the samples collected.
At the same time, the national environmental protection agency also pointed out that, because about 1/5 of the United States family houses did not connect public sewers, only the local septic tank system was used. This means that monitoring the use of waste water to assess the level of COVID-19 communication in the United States still has some limitations, and can not fully reflect the severity of the epidemic in the United States.
