Zhengzhou epidemic confirmed by COVID-19 delta strain! These matters need attention!

   Epidemic situation is an order, and prevention and control is a responsibility     Don’t relax when the epidemic situation repeats   confirm one’s confidence     to pull together in times of trouble     Scientific prevention and control     Precise strategy    From 0:00 to 24:00 on August 1, 2021, there were 3 newly confirmed cases in Henan Province, including 2 imported cases and 1 local case (1 case in Shangqiu City); 28 cases of asymptomatic local infection were added (27 cases in Zhengzhou and 1 case in Zhumadian); No new suspected cases

.

As of 24:00 on August 1, 2021, a total of 1286 locally confirmed cases have been reported in Henan Province, including 22 dead cases, 1251 discharged cases and 13 hospitalized cases

.

A total of 61 confirmed cases imported from abroad were reported, 43 cases were discharged and 18 cases were treated in hospital

.

A total of 41661 close contacts were tracked and 287 close contacts were still under medical observation

.

Zhao Dongyang, deputy head of the integrated control unit of the Henan provincial epidemic prevention and control command office, was identified by the deputy director of the Zhengzhou Provincial Center for Disease Control and prevention, said the provincial CDC’s orderly sequencing of the virus and its comparison with the recent imported case strains from the current results, according to Zhao Dongyang, the deputy director of the Provincial Center for Disease Control and prevention

.

The epidemic is mainly caused by COVID-19 delta strain

.

What are the characteristics of delta strain? Delta strain has become the most important strain in the global epidemic

.

It has spread to 104 countries and regions around the world, and continues to mutate in the transmission

.

According to the previous epidemic situation, delta virus has several new characteristics in clinical manifestations: strong virus transmission, fast transmission speed, high body load, atypical symptoms, slow negative conversion speed of patients, long treatment time, and prone to severe diseases

.

Russian immunologist remchugov said that if a person is infected with several other new coronavirus strains, it will infect only 2-3 people on average, while those infected with delta variant strains will infect 6-8 people

.

Academician Zhong Nanshan said in an exclusive interview with reporters not long ago that in the transmission of “delta” mutant strain, the main and severe patients are mostly the elderly and children

.

Therefore, vaccination should be strengthened in these two groups

.

Still infected after vaccination? Is vaccination still useful? Do not relax

.

Among the newly confirmed cases reported continuously in China recently, some cases have been vaccinated before

.

Why are they still infected after vaccination? Is vaccination still useful? In this regard, many experts have pointed out on different occasions that infection after vaccination does not mean vaccine failure

.

Academician Zhong Nanshan said in an interview with reporters earlier that the whole virus inactivated vaccine must have a protective effect

.

In particular, after checking the delta strain, it was found from the laboratory data and more than 160 limited data in Guangzhou that the close contacts used the vaccine, the whole process of vaccination and the whole process of vaccination were not used, and its protective effect can be seen, It has more than 60% protective effect on infection and nearly 80% protective effect on severe cases

.

How to do epidemic prevention in the face of Delta? Since I started, academician Zhong Nanshan said in an interview with the media that due to the high viral load, high concentration of exhaled virus and strong infectivity of delta mutant patients, the past concept of close connection is no longer applicable

.

Now the concept of close contact is “in the same space, the same unit, the same building, four days before the onset of the disease”

.

Those who get along with patients are close contacts

.

In the face of delta virus, the provincial CDC reminded the people of the whole province to improve their awareness and ability of epidemic prevention from the following five aspects: first, make reasonable travel arrangements in the near future and reduce cross provincial travel

.

If it is not necessary, do not go to medium and high-risk areas

.

If you really need to go, do personal protection throughout the whole process and accurately record your activity track, After returning to Henan, it is necessary to take the initiative to report to the community (Village) where it is located and cooperate with the implementation of relevant prevention and control measures

.

Second, we should comprehensively strengthen personal protection in daily life, scientifically wear masks in all public places and public transport, maintain good health habits such as frequent hand washing, regular ventilation and reasonable social distance, and do not get together and gather

.

Third, we should always pay attention to the physical health of individuals and their families

.

In case of fever, cough, sore throat, fatigue, decreased sense of smell (taste), diarrhea and other symptoms, do not treat yourself

.

Wear a mask in time to go to the nearest fever clinic or designated medical institution for treatment and investigation, truthfully inform your personal residence history, activity history and contact history, and try to avoid taking public transport during medical treatment

.

Fourth, actively cooperate with various epidemic prevention and control activities and measures organized by the government, such as nucleic acid detection, community control, etc; The current research data show that China’s vaccine still has good protection effect

.

For example, the research data of Kexing company in the real world in Chile show that the overall protection of China’s inactivated vaccine is more than 65%, and the prevention and protection of severe diseases is more than 87%

.

Here we also remind you to actively vaccinate, improve the awareness of vaccination in the whole process, and speed up the establishment of population immune barrier

.

After vaccination, personal protection can not be relaxed

.

The two means should be combined to play a protective role to the greatest extent

.

Fifth, we must obtain the epidemic prevention and control trends from official channels, do not believe, spread or spread rumors, and strengthen our confidence in overcoming the epidemic

.

Affected by the novel coronavirus pneumonia, 31 PM, Zhengzhou Railway Station, Zhengzhou airport and north passenger station have issued news

.

If the passengers are to be removed from the above way, they must have negative nucleic acid test within 48 hours

.

At present, some communities in Zhengzhou have begun to do nucleic acid testing

.

Remind! The following precautions should be paid attention to in nucleic acid testing to prevent and control the epidemic

.

Guo Yonghao, director of the laboratory of the Institute of immunization planning of Henan CDC, said: the main precautions for nucleic acid testing can be summarized as “three needs” and “three don’t”“ The “three musts” mainly include: first, wear masks in the whole process, wear masks before and after nucleic acid testing, pay attention to keeping a distance from others and do personal protection; Second, open your mouth

.

When sampling pharyngeal swabs, you must open your mouth to make a “ah ah” sound, so that medical staff can ensure sampling; Third, exercise restraint as much as possible, which means that it will inevitably bring people the feeling of retching and choking when sampling throat swabs, but exercise restraint as much as possible and don’t let yourself spit out, because vomiting will bring great risks“ “Three don’t” mainly refers to: first, don’t smoke or drink, don’t smoke or drink before nucleic acid testing, and keep your mouth clean; Second, do not touch the sampling items, including the sampling personnel, the sampling table and the items on the sampling table, and do not put your personal belongings on the sampling table, such as ID card, key, mobile phone, etc., and keep a reasonable distance from the sampling personnel; III

.

do not touch the outer surface of the mask

.

At the nucleic acid testing site, do not touch the outer surface of the mask with your hand whether you take off the mask or wear the mask

.

It is best to remove the mask belt hanging on the ear from the ear root, and gently take it off and wear it

.

As for whether nucleic acid detection can be carried out for people with colds, Guo Yonghao said that it does not affect the nucleic acid detection, and cold fever does not affect the nucleic acid detection

.

Pharyngeal swab sampling can be carried out normally

.

In the special period of epidemic prevention and control, let’s always be vigilant, do a good job in personal protection, obey community arrangements, join hands in fighting the epidemic, overcome difficulties, and escort the healthy growth of children! Ignite the light of life with love and enlighten the gate of wisdom with morality
