Variant virus | It is worth noting that the Mu variant of WHO has recorded two cases in Hong Kong without an announcement from the Department of Health

The global epidemic is still severe, and the World Health Organization warned that the world should pay attention to the Mu variant virus.

A doctor revealed that there have been two patients with Mu mutant virus in Hong Kong recently, and the mutation position of Mu will weaken vaccine neutralizing antibodies.

Another expert said that the transmission and lethality of the Mu variant has not been strengthened, and will not replace the Delta variant virus for the time being. They believe that the world has the responsibility to continue to prevent the epidemic and prevent the virus from mutating faster than the improved vaccine formula.

The Department of Health has never disclosed two cases of Mu mutant virus in Hong Kong.

The Director of the Infection and Infectious Diseases Center of the University of Hong Kong, Ho Pak-liang, said on a commercial radio program today (3rd) that he noticed two cases of the Mu mutant virus in Hong Kong in the online gene bank, and believed that the CHP should explain to the public to make the society clearer. Master the epidemic.

He Boliang said that according to Mu's genetic map, its S protein has nine positional mutations, including N501Y, E484K, and P681H. According to past experience with mutant viruses, the positional change will weaken the new crown vaccine's neutralizing antibody.

He said that Mu was first discovered in Colombia, with about 4,500 cases worldwide, with the United States accounting for the most, followed by countries such as Colombia and Chile.

He emphasized that vaccination is still the most powerful prevention and control tool.

According to the public gene bank, two cases of Mu patients have been recorded in Hong Kong, but the Center for Health Protection has never announced them.

Liang Zichao, a specialist in respiratory medicine, pointed out that there is no evidence to show that the Mu variant virus has a stronger survival advantage and will not replace the Delta variant virus for the time being, and its lethality has not been enhanced.

He pointed out that if the vaccination rate and infection rate are high in areas with a new variety of mutant virus, it means that the virus has a strong immune escape ability and the situation is quite dangerous.

Super variant of the virus will respond liangzi made three recommendations:

1. people vaccinated as soon as vaccine effective in preventing severe

2. pharmaceutical companies "do not attempt to sell caught a third needle" vaccine formulation study as soon as possible to catch up with the speed of virus variants

3. Even if the vaccination rate is high, governments of all countries must maintain certain epidemic prevention regulations, including wearing masks, "continuously spreading, that is to encourage the virus to continue to mutate, and then export more than the world."
