The variant virus Omicron is raging around the world. After the team of Yuan Guoyong of the Faculty of Medicine of the University of Hong Kong became the first in Asia to successfully isolate and cultivate the virus strain Omicron, today (8) the Faculty of Medicine announced the "real body" photos of Omicron virus-infected cells.

Researchers analyzed monkey kidney cells (Vero E6) infected with the Omicron mutant strain of the new coronavirus under a low-power electron microscope.

The photo shows damaged cells and swollen vesicles containing black small virus particles.

The photo also shows a virus particle with a crown-shaped spike protein on its surface.

The Department of Health announced yesterday (7th) 5 new imported confirmed cases. Among them, 4 patients were confirmed to have the L452R variant virus. To date, there have been 12,472 cases in Hong Kong, and an 80-year-old male patient is in critical condition.

There are fewer than 5 initial confirmed cases, including a 61-year-old man who returned to Hong Kong from Ghana, West Africa in the middle of last month. He returned to the community after completing the quarantine of the hotel on the 14th. The compulsory test was positive. Due to the low virus load and the diagnosis in Ghana in September, it was classified as a Fuyang case.

Under the electron microscope, Omicron attacked cells at the same location as previous mutant virus strains such as Delta. There is no further evidence that Omicron's power is enhanced.

Xu Shuchang: Many countries require three shots of Kexing Omicron to be less lethal than Delta

[11:02] A research team led by Xu Shuchang, Chair Professor of Respiratory System Department of CUHK and a government expert consultant, showed that the level of neutralizing antibodies produced by vaccination with Fubitai was significantly higher than that of the vaccination with Kexing.

Xu said in a radio program today (8th) that because the level of antibodies produced by Kexing is not high, only 16% of the people who received two injections of Kexing had qualified antibody levels for half a year. He believed that people who were vaccinated by Kexing should give priority to the third. Needle.

He said that many countries require three injections of Kexingcai as "complete vaccination", such as Singapore.



Xu also pointed out that existing data show that the lethality and death rate of the variant virus Omicron seems to be lower than Delta, but he emphasized that it is still too early to say, because some people are still in the doctor and the final result is unknown, so far there is not enough data to make a conclusion.

Xue Jinping, community organization officer of the Hong Kong Association of Community Organizations, stated in a radio program today (8th) that the Social Association is one of the non-governmental organizations that issue certificates of exemption to the homeless. Thousands of homeless applications will be processed within days.



She also pointed out that some people do not necessarily want to disclose the identity of the homeless, and that the speed of receiving information for the homeless is relatively slow. Therefore, it is estimated that there will be "fish that slip through the net" that cannot be issued with an exemption certificate.
