The Delta strain has caused more than 300 infections in 15 provinces (as of 1 August), eight of which are severe. The number of high - and medium-risk areas in China has risen to 94. On August 1, Beijing upgraded its control over the wrong practices and strictly controlled the entry of people from medium-high risk areas. Other 29 provinces and cities have also ordered "not to go out of provinces and cities".

Despite strict emergency tracking, quarantine and lockdown measures, the outbreak is still developing. It is noteworthy that the vaccination rate of Nanjing Airport staff has reached about 90%, but it has not stopped the spread of the epidemic.

How contagious is Delta?

Recently, the WHO announced that Delta has become the most prevalent strain in the world, affecting more than 120 countries. Global daily new cases rebound on Delta.

The Delta variant was first identified in India in October 2020 and was the main circulating strain in the second wave of the outbreak in India in April this year. After the outbreak in India, the Delta variant began to sweep the world.

Academician Zhong Nanshan previously said in an interview that patients with the "Delta" variant have high viral loads, large exhaled viral concentrations, and are highly contagious, so even the concept of close contacts before must be adjusted. Now a close contact is someone who spends time with the patient "in the same space, in the same unit, in the same building, four days before the onset of illness."

As the epidemic continues and the virus continues to spread, the mutation of the virus will continue to accumulate. In the face of the epidemic of the mutant strain, we need to strengthen prevention and control measures in all aspects: the frequency of rapid testing of COVID-19 nucleic acid should be increased, epidemiological investigations should be accelerated, and vaccination should be accelerated.

Since the outbreak of COVID-19, in order to improve detection efficiency, Fosun Beiling has provided safe, efficient and fast high-throughput rapid detection solutions, and launched a series of products to combat COVID-19, including: liquid processing workstation, automatic nucleic acid extraction instrument, and 5G+ mobile microbial detection vehicle.

The above liquid processing workstation and automatic nucleic acid extraction instrument can be configured in Fosun Beiling 5G+ mobile microbial detection vehicle.

Using the integrated design of "biosafety level 2 + vehicle", it is a "walking nucleic acid detection laboratory", which can break through the territory, that is, stop and check, reach any place where the road is, and protect the last kilometer of epidemic prevention and control.

The cabin can be equipped with liquid processing workstation, automatic nucleic acid extraction instrument, QPCR detector, with high throughput and rapid field detection capabilities.
