Liang Zichao: It is normal for local outbreaks of local infection cases to vary

Respiratory system expert Liang Zichao said in an interview with Hong Kong 01 that there will be no sixth wave in the next two weeks. Taking Indonesia and the Philippines as examples, the two countries also experienced a full-scale outbreak of Omicron, and dropped sharply after the peak, and the number of cases remained at Hundreds of cases.

The immediate transmission rate is in the "running rampant" stage, reflecting the slowdown in the epidemic, similar to that in Hong Kong.

Liang Zichao believes that it is normal for occasional outbreaks in local areas, and explained that the cumulative infection rate in the Central and Western District was only 5% to 6%, while the infection rate in other areas, such as Wong Tai Sin, has reached 12% to 13%.

After the government relaxed social distancing measures, a large number of citizens in the district went out, and the chance of infection among the uninfected population increased greatly, resulting in local outbreaks.

Urge to tighten regional arrival requirements from new variant virus

Liang Zichao said that the Omicron subvariant virus invaded South Africa and the United States and became the mainstream virus.

If the new variant flows into the community, I am afraid it will repeat the mistakes of the fifth wave and induce the sixth wave, so the key to whether the sixth wave will break out if the external defense input becomes the sixth wave.

He suggested that the government tighten the arrival requirements for areas with new variants of the virus and strengthen monitoring, while suggesting that arrivals use isolation facilities instead of quarantine hotels for quarantine.

He also pointed out that the nucleic acid test currently carried out on the fifth day should be postponed to the seventh day to ensure that the risk of the virus entering the community is reduced.
