Epidemic｜XBB.1.5 first entered the mainland of Hong Kong and rumored of fecal incontinence? Experts: No scientific basis

The new crown pneumonia epidemic continues, and Hong Kong has recorded the first case of XBB.1.5 virus strain among imported cases.

The WHO said earlier that the strain in question was the most contagious strain found so far, but it did not appear to cause more serious illness.

However, mainland netizens have gone viral recently. After this virus strain is prone to cause diarrhea, it further claims that it can cause "involuntary diarrhea", that is, fecal incontinence.

Xu Shuchang, a government expert consultant, Jin Dongyan, a professor of the School of Biomedical Sciences of the University of Hong Kong, and Liang Zichao, a specialist in respiratory system, all said that the rumors of diarrhea have no scientific experiments, and they believe that the relevant virus strains will not spread in Hong Kong, so citizens do not need to worry too much.

Although the number of confirmed cases in Hong Kong has dropped slightly, Hong Kong has recorded the first case of XBB.1.5 virus strain among imported cases.

The XBB.1.5 imported case involved a 24-year-old woman who arrived in Hong Kong from the UK and had received two doses of vaccine. She was a confirmed case.

According to the data, XBB.1.5 accounts for nearly 40% of the virus strains infected in the United States, and more than 75% of the cases in the eastern United States are infected with XBB.1.5.

Cases of XBB.1.5 have also appeared in France, Germany, the Netherlands, Spain, Ireland, Australia, Singapore and India, and China is reported to have imported cases as well.

WHO refers to the XBB.1.5 virus strain as the most contagious, first discovered in New York

The currently popular XBB.1.5 is a sub-variant of XBB, which was first discovered in New York, USA 3 months ago. It has mutations in genes such as F486P and S486P, which allow it to evade the new coronavirus antibodies and increase after vaccination or infection. The ability of viruses to bind to cells.

Since XBB.1.5 has become the mainstream virus strain in the United States in a short period of time, the WHO stated earlier that the related virus strain is the most contagious virus strain discovered so far, but it does not seem to cause more serious illness.

However, mainland netizens have gone viral recently. After this virus strain is prone to cause diarrhea, it further claims that it can cause "involuntary diarrhea", that is, fecal incontinence.

Xu Shuchang: Rumors of diarrhea have no scientific basis

Xu Shuchang, an expert consultant to the government, said that the symptoms caused by XBB.1.5 are similar to those caused by other mutated virus strains, and there is no scientific experiment to denounce rumors of diarrhea.

Jin Dongyan, a professor at the School of Biomedical Sciences of the University of Hong Kong, also pointed out that the statement has no scientific basis.

As for the ability of the virus to spread, he believes that Hong Kong has recorded more than 200 imported cases of XBB.1 and more than 100 local cases of XBB.1 in the past, but it has never become the mainstream virus strain in Hong Kong. At present, BA.5 is still dominant and BA.4, so I think you don't need to worry too much.

Jin Dongyan is expected to cause another wave of epidemics, the chance is very low

He also explained that people who have been naturally infected with BA.2 or BA.5 or who have been vaccinated with bivalent vaccines have very little chance of secondary infection or breakthrough infection with XBB.1.5, so the chance of XBB.1.5 causing another wave of epidemics is very small low.

Take the United States as an example, although the proportion of XBB. The situation in Hong Kong will not change either.

Liang Zichao questioned the strength of communication

Liang Zichao, a specialist in the Department of Respiratory System, pointed out that although the WHO said that the relevant virus strain is the most contagious virus strain discovered so far, this is all laboratory data, and it believes that it ignores the immunity of cellular immunity to mutant virus strains.

He also believes that the related XBB.1.5 virus has appeared in the United States for three months. If its transmission can explode in a short period of time, it is unlikely that the increase will only occur now. He questioned the United States or "fake reporting".
