In the face of the Delta virus invasion, Taiwan has adopted high-standard listings, and all contacts who have contacted them have been isolated. But now for days of “Carina”, Huang Limin, director of the National Taiwan University Children’s Hospital, believes that the isolation policy must be reassessed and the CP value must be considered. However, physician Shen Zhengnan emphasized that coexisting with the virus is wrong, and cited an example of a record high number of cases in Singapore. The number of confirmed cases is still rising after vaccination. He emphasized that precise epidemic investigation and isolation must not be let go.
A few days ago, the Delta mutant strain and the kindergarten gathering incident, the command center did not dare to be careless, and all the contacts of the contacts were isolated! However, in the tracking guidelines published in the past, there is no such provision. In addition to the recent slowdown of the epidemic, experts believe that preventive isolation is still subject to discussion.
Huang Limin, director of National Taiwan University Children’s Hospital, pointed out, “If your first contact has not yet begun to be infectious, you should isolate his contacts. This is unnecessary in itself, because he himself will not spread the virus. , How could the people he contacted be dangerous? We know that one or two days before the end of the incubation period, they may be contagious. If you have contacts in the first one or two days, you have to isolate him. Then this is justified. It still depends on the results of the epidemic investigation. .”
Taiwan is still exploring strategies to fight against Delta. The international epidemic prevention strategy has also shifted from zeroing to coexistence with the virus. However, physician Shen Zhengnan emphasized that coexisting with the virus is wrong. The vaccine is actually not as effective as expected, and it cannot be overly dependent on vaccines. Look at Singapore, which has a high vaccination rate. The number of cases has hit a new high recently. Therefore, precise epidemic control and isolation must not be let go. Masks are still the key to epidemic prevention.
Professor Chen Xiuxi of the National Taiwan University School of Public Health said, “Although it can’t find out the fast home screen, the Ct value is very high and the virus load is very low, but it has a high virus load and a low Ct value. This kind of recessive transmission chain suddenly occurs. Recessive infections that may infect other people will have a very good effect of blocking early detection.”
In the face of the difficult Delta virus, public health expert Chen Xiuxi believes that in the future, we must continue to accurately prevent the epidemic. In addition to strengthening the frequency of screening, we must also increase the coverage of the second dose of the vaccine and study the possibility of mixing. In addition, the footprint survey or the history of going abroad can be assisted by technology to connect the central and local governments.
Lin Shijia, CEO of the Taiwan Medical Federation Foundation, said, “Go and contribute my information, as long as it is de-identified, such as where I go in and out, whether I have been vaccinated, when I was screened quickly, and when I When entering the high-speed rail station, it may not know my name, but it knows that I am a safe person to come in. As a high-speed rail station, it can manage all areas and it is safe.”
Experts dare not relax. In the face of an endless epidemic, epidemic prevention strategies must be constantly adjusted and prepared at any time!
