The new crown pneumonia epidemic has been repeated. Earlier, the government tracked the confirmed cases through sewage monitoring.
The Secretary of the Environment Huang Jinxing stated on a commercial TV program this morning (2nd) that due to the decline in the number of confirmed cases, the monitoring strategy will be changed from upstream, that is, from areas and housing estates with confirmed cases, to monitoring points in the "middle and lower reaches". A monitoring site covering 18 districts will conduct background monitoring on half or more of the district population in Hong Kong, that is, over one million people. Once positive samples are found in some areas, they will be searched upstream.

Huang Jinxing stated on the commercial TV program "Starting on a Sunny Day" that sewage monitoring is an "emerging scientific research". Preliminary data shows that its accuracy is 90%. It has successfully identified more than 50 virus carriers before.
For some of them who may be recovered, but the excrement still contains the virus, Huang Jinxing said that he has anticipated the relevant situation, and various departments will comprehensively analyze the relevant data.

Recently, the number of newly confirmed cases has dropped. Huang Jinxing said that sewage monitoring will be changed from upstream, that is, from the housing estates and districts that have positive samples in monitoring tests, to the middle and downstream, that is, dozens of relevant monitoring points will be set up in 18 districts in Hong Kong. Each monitoring point can track a population ranging from thousands to tens of thousands, and is expected to cover half or more of the population of Hong Kong.
He continued to point out that once the virus is found, it can be used to track it upstream to find out which building or housing the source came from.

The current sewage monitoring is carried out by the University of Hong Kong. Huang Jinxing said that he is responsible for scientific research and technology, so the current monitoring work will be changed to two commercial laboratories.
He revealed that since the end of last year, the current sewage testing capacity has increased by about eight times. It is estimated that when commercial laboratories join in, it will double again.

Huang Jinxing: Tax relief will be reduced after electric vehicles are mainstreamed
Huang Jinxing also talked about the development of electric vehicles on the show.
He said that according to global experience, when electric vehicles are mainstreamed, relevant tax relief will gradually decrease. Take Norway as an example, which is a developed country in the world for electric vehicles. For every two newly registered vehicles, one is an electric vehicle. The country has recently reduced discounts for electric vehicles.
Regarding whether Hong Kong will refer to the Norwegian experience, Huang pointed out that in addition to the number of electric vehicles, the price difference between electric vehicles and petrol vehicles must also be considered. The former is always more expensive, so its license fees and taxes are lower than petrol vehicles in order to increase the switch to electric vehicles. Incentives.
