Is it concealing trouble? 6 cases were confirmed, and a building in Guangzhou was isolated overnight!
This article is from China Fund Newspaper 2020-02-12 22:50:57

Since the occurrence of the new crown pneumonia epidemic, patients have been vocalizing concealment of their schedules and conditions, which has brought great risks to the entire prevention and control work.

Yesterday, a patient in Shandong who had concealed his trip and did not cooperate with the investigation appeared to be cured. The police greeted him. At nearly one o'clock today, Guangzhou Haizhu District issued a notice, suspecting that the family had concealed the illness, and the entire building in Pazhou was centralized and isolated.

Suspicious of a family's concealment, the entire building in Pazhou, Guangzhou was concentrated and isolated! Police have filed an investigation

According to Guangzhou Daily, at 00:56 on February 12, Guangzhou Haizhu released an official Weibo to issue a notice: a centralized isolation medical observation was carried out on a building in Pazhou to ensure the health and safety of the residents.

It was later confirmed by the developer that the property was Poly Tianyue. It is understood that the highest property price has reached 100,000+.

On the evening of the 11th, the owner of the building received a property notice: Three new crown virus pneumonia outbreaks have occurred in 18 buildings of the building. According to multiple on-site investigations and discussions by provincial and municipal experts, it is believed that the building may still have unknown sources of infection, and it is not ruled out to continue to pass. The spread of the epidemic has been spread by sharing elevators or spreading through sewage pipes. Therefore, for the safety and health of each resident, the expert group recommends that all occupants of this building be moved out to implement centralized medical observation.

Today's Guangzhou Daily reporter learned from Guangzhou Haizhu District that Poly Tianyue 18 or the owner concealed the report and finally confirmed the diagnosis. As a result, the entire building was isolated by the disease control department. The Guangzhou Daily reporter combed the whole from the relevant departments of property, public security and Haizhu District. Case development restores Poly Tianyue epidemic

January 30

The property started to warn Poly Tianyue Garden Service Center is now reporting two cases of pneumonia confirmed on January 29 in Pazhou Xincun District.

On February 4th, Haizhu District Public Security Subcommittee initiated a case investigation on Yumou. On February 4, 2020, Haizhu District Public Security Subcommittee conducted a lawful investigation on the property owner Yumou (male, 33 years old, who was diagnosed with a new type of coronavirus on January 31st). Infected patients with pneumonia have now been quarantined and admitted for investigation.

On February 12, an emergency notice was issued in Haizhu District, and 18 households were notified to be quarantined.

Poly Tianyue has confirmed cases in succession, 6 confirmed

According to the "Notice on Epidemic Prevention and Control Work in Poly Tianyue Community" issued by the Office of the Epidemic Prevention and Control of Pazhou Sub-district Office in Haizhu District, as of February 11, a total of 3 confirmed cases of pneumonia caused by new-type coronavirus have been reported in Poly Tianyue Community. A total of 6 cases, 3 households were located on the 15th, 25th, and 27th floors of 18 buildings, respectively. No new suspected cases were found. The confirmed cases have been placed in isolated treatment at designated hospitals in Guangzhou, and their close contacts have been sent to designated places for medical observation.

At 10:11 today, the Guangzhou Municipal Health and Health Commission reported that the new cases involved communities or places. Among them, Poly Tianyue in Haizhu District was once again on the list. From 00:00 to 24:00 on February 11, 2020, there were 6 new confirmed cases in Guangzhou, which were found to involve 3 districts, 4 communities or places. Immediately after the diagnosis was found, the disease control department has carried out strict terminal disinfection on the communities involved, and supervised and guided the community and the property to do routine preventive disinfection. Case-related close contacts have been sent to the designated places for medical observation. I hope you don't panic, and don't care too much about the cases in your community. Both communities with and without cases should do a good job of prevention and control. Even in communities without cases, personal protection is required.

....Michael Osterholm, director of the Centre for Infectious Disease Research and Policy at the University of Minnesota, said it was possible it could be transmitted by people before they become ill and there were “striking parallels” between Covid-19 and the flu virus, which can infect others during the incubation period.

“The epidemiology screams ‘flu virus-transmission’,” he said.

“With Sars, the majority of transmission took place between four to six days of illness so patients could be identified in the first several days of infection and isolated, which slows down the transmission.

“I think this virus does not act that way.”

Osterholm did note, however, that it would be “very, very unusual” for such a disease to have a 24-day incubation period, and it is likely such patients could have had a later exposure to the disease without being aware.....

Possible Treatments
The 2019-nCoV and SARS-CoV (severe acute respiratory syndrome-related coronavirus, GenBank ID: NC_004718.3) share a very high sequence identity on their RdRp and 3CLpro proteins. Remdesivir (developed as a treatment for Ebola virus disease) and 3CLpro-1 are small-molecule antiviral drugs that might have activity against SARS-CoV. Remdesivir is undergoing clinical trial. The researchers recommend using remdesivir and 3CLpro-1 to treat the 2019-nCoV. The Chinese authority may negotiate with Gilead Sciences, Foster City, CA, USA, in the possible use of remdesivir for patients suffering from the 2019-nCoV.

Expert: New crown virus may be mixed with influenza virus, which will interfere with epidemic prevention and control

Wu Yan / Guangzhou Daily Client

2020-02-12 20:48

Guangzhou Daily Client February 12 news. Yesterday, the "Chinese Journal of Preventive Medicine" published a Guangzhou public health expert's paper "While fighting the epidemic of new coronavirus pneumonia while alerting to the additive effects of seasonal influenza."

The article points out that the outbreak of new coronavirus pneumonia continues to spread throughout the country, and the epidemic prevention and control has entered a critical period.

However, the severely affected southern cities are about to enter the season of high seasonal flu. It is necessary to strengthen epidemiological investigations, optimize laboratory testing strategies, take effective measures to increase the intensity of influenza epidemic prevention and control, and minimize interference with the prevention and control of new coronavirus epidemics.

Research and judgment on the new crown pneumonia epidemic situation: At present, it is basically stable, and the risk of community transmission cannot be ignored during 15-30 days after early February.

The first author and corresponding author of the paper are Li Tiegang, deputy director of Guangzhou Chest Hospital, and Wang Ming, an expert on special allowances of the State Council. The author judges that if the epidemic that is limited to Wuhan and surrounding areas in December 2019 is regarded as a local epidemic stage, then the current epidemic has entered a "stalemate" stage under national mobilization and the struggle of the entire population. Hubei Province The rapid increase in newly diagnosed cases has shown signs of slowing.

"From the data released by the National Health Commission, although the number of newly diagnosed cases in other regions of the country is unevenly distributed, it is basically stable. However, from the half month or one month after the beginning of February, the new type of crowns nationwide The virus pneumonia epidemic will again face the severe test of the flow of people after the Spring Festival. The possibility of large-scale outbreaks in areas affected by the epidemic is small, but the risk of community transmission cannot be ignored. This is the most important issue in the prevention and control of the epidemic. Facing severe challenges. "Corresponding author Wang Ming introduced.

Experts point out that at this critical point, we must conduct objective analysis of the epidemic situation more rigorously and prudently. In addition to timely research and judgment of the epidemic situation of new coronavirus pneumonia, we must also understand other factors that may have an impact on epidemic prevention and control. Adjust prevention and control strategies in a timely manner, and adopt scientific and effective means to curb the development of the epidemic.

At least 1 out of every 10 people in the flu season, if treated as a new coronavirus infection, it will adversely affect prevention and control

According to disease surveillance data, other respiratory infectious diseases such as influenza virus, parainfluenza virus, adenovirus, respiratory syncytial virus, rhinovirus, human metapneumovirus and other related diseases are about to enter the epidemic season together with new coronavirus pneumonia, Its clinical manifestations are similar to those of new coronavirus pneumonia, which is difficult to distinguish by clinical manifestations and chest imaging.

These respiratory viruses are mixed in the current new coronavirus pneumonia epidemic, which not only interferes with the prevention and control of the epidemic, but also threatens the health and safety of the public. A slight laxity in prevention and control can cause emergencies. Therefore, from the perspective of public health, it is also very important to identify and prevent these respiratory viruses. "Among them, the influenza virus needs us to be vigilant." Wang Ming emphasized.

As we all know, influenza viruses are highly contagious, spread rapidly, and present a global epidemic. According to the World Health Organization, influenza can cause disease in 5% to 10% of adults and 20% to 30% of children each year. This means that during the flu season, at least one in 10 people is infected with the flu.

Influenza virus can cause serious complications such as severe pneumonia or co-morbidity with other bacterial infections and cause death. The annual global influenza epidemic can cause 650,000 deaths, which is equivalent to one death from the flu every 48 seconds. At the same time, influenza virus is also the main pathogen of outbreaks of respiratory diseases in the population.

It is worth noting that the peak season of influenza epidemic in China shows a north-south difference, with northern regions appearing in autumn and winter and southern regions appearing in spring and summer. At present, the provinces with severe outbreaks of the new type of coronavirus nationwide are mainly concentrated in the south, such as cities in Hubei, Guangdong, Zhejiang, Hunan and other provinces. These cities are about to enter the season of high influenza incidence, which is expected to continue until July to August.

Judging from the recent trend of the new coronavirus epidemic, the performance is inconsistent across regions. The number of daily reported cases in some regions does not seem to have reached the "top", and the epidemic is difficult to end in a short period of time. Its epidemic trend is likely to be integrated into the influenza season. This means that more cases of fever will be monitored, and the identification and difficulty of identifying cases will further increase. If fever cases cannot be detected in a timely manner in the laboratory, influenza cases are likely to be treated as new coronavirus infections, thereby adversely affecting the prevention and control of new coronaviruses. In fact, during the previous influenza season, it was difficult for the CDC to conduct laboratory tests on all influenza viruses.
May explore the feasibility of current flu vaccination

Therefore, the author of the paper believes that, on the one hand, test kits that integrate new coronaviruses and common respiratory viruses should be developed as soon as possible, which can be convenient, fast, and suitable for popularization at the grassroots level; relevant departments should emphasize laboratory quality control in clinical and disease control departments For example, to ensure that the detection reagents used have better sensitivity and specificity, to prevent laboratory contamination, etc., to minimize misdiagnosis, missed diagnosis and late diagnosis.

On the other hand, in the practical situation of limited experimental detection capabilities, epidemiological investigations should be strengthened, and suspicious cases should be classified and managed, and priority levels should be assigned to ensure that key cases can be timely investigated.

Furthermore, in view of the importance of influenza prevention and control, in order to minimize the incidence of influenza in the population and to alleviate the confounding and interference of new coronavirus prevention and control, the feasibility and possibility of promoting influenza vaccination can still be explored.

Ming Wang said that especially the southern urban residents, because the flu peak occurs in the spring and summer season, according to the law of antibody production after vaccination, influenza vaccination still has the role of "repairing sheep", and it will also be extremely helpful to the overall epidemic prevention and control in the future.

There may be mixed infections. If the influenza virus test is positive, the new coronavirus must still be checked.

In addition, experts reviewed the data during the SARS period and found that from late January to mid February 2003, Guangzhou SARS entered a stage of rapid growth. In the same period, the positive rate of influenza virus isolation in cases of fever and cough / pharyngeal pain was 5%. SARS The positive rate of influenza virus isolation throughout the epidemic year was 13%.

In addition, serological surveys during the 2009 H1N1 epidemic also confirmed that 3.27% of confirmed cases of H1N1 influenza were also infected with seasonal influenza.

It can be speculated that the new type of coronavirus and seasonal influenza may also have mixed infections, or simultaneous infections, or successive infections in a short period of time, and the cases of combined infections may have more severe clinical manifestations and a longer course of disease.

Based on the above analysis, experts believe that during the detection of respiratory cases, if a seasonal influenza virus is detected, further detection of new coronavirus is also needed. Even if the new coronavirus test is negative, for special cases, such as close contacts, people in the epidemic area, etc., continuous observation is required for 14 days, and the new coronavirus test will be performed again at the end of the observation.

In addition, it is necessary to incorporate the new coronavirus into the pathogenic spectrum monitoring system of community fever cases, to grasp the epidemic status of the new coronavirus and other respiratory pathogens in time to guide clinical practice and epidemic prevention and control.

The top 5 priorities Xi was quoted as saying on Feb 10, 2020

snip

The first is to resolutely receivable. Controlling the source and cutting off the transmission route are the fundamental measures to prevent and control infectious diseases. We must take more effective measures to increase the number of beds in medical institutions as soon as possible, make good use of the square cabin hospitals, and increase the number of isolated beds through the acquisition of hotels and training centers, and do our best to treat patients.

The second is to do a good job in rescue work. In accordance with the principles of centralized patients, experts, resources, and treatment, we must continuously optimize the diagnosis and treatment plan, adhere to the integration of traditional Chinese and western medicine, increase research efforts, and speed up the development of drugs with good clinical efficacy.

The third is to comprehensively strengthen social control. It is necessary to strengthen social governance and properly deal with various problems that may arise in the prevention and control of epidemics. All work must be meticulous and detailed, and work such as life security, medical treatment and psychological intervention must be put in place to maintain the stability of the overall society.

The fourth is to strengthen the guidance of public opinion. In-depth propaganda of the CPC Central Committee's decision-making and deployment, attention to Hubei and Wuhan, promotion of the hardship of one party and the love of the eight parties, and promotion of the touching deeds of frontline medical staff, grass-roots cadres, public security police, community workers, volunteers, etc. The strong will of the people of all ethnic groups throughout the country to strengthen confidence and help each other. Authoritative information should be released in a timely manner, responding to public concerns transparently and transparently, and enhancing the pertinence and effectiveness of public opinion guidance. It is necessary to increase the publicity and education of the law on prevention and control of infectious diseases, to guide the whole society to prevent and control according to law, and to improve the people's ability to protect themselves.

The fifth is to strengthen the unified command of epidemic prevention and control. The Central Leading Group for Epidemic Response should fully implement the requirements of the Party Central Committee and focus on epidemic prevention and control in key areas. The State Council's joint prevention and control mechanism should strengthen coordination and dispatch to give priority to ensuring epidemic prevention and control in Wuhan and other key areas. The Central Steering Group must guide and strengthen supervision and control of Hubei and Wuhan. Hubei and Wuhan should take epidemic prevention and control as the top priority at present, coordinate and strengthen the epidemic prevention work in cities, counties, and counties, improve the command system, respond decisively and quickly, operate efficiently and orderly, and implement resolutely.

Aerosol transmission of new coronavirus inconclusive
2020-02-13 06:45:22 Source: Sichuan Daily 日 Editor: Gu Qiang
Mobile access

Sichuan Online Reporter

Recently, news that relevant coronaviruses reported by relevant media may be transmitted through aerosols has aroused great public concern. Is the New Coronavirus transmitted through aerosols? What protective measures do families and individuals need to take? At a press conference (the third session) on the prevention and control of the new coronavirus pneumonia in Sichuan Province, a reporter asked this question.

Zhang Jianxin, a professor at the West China School of Public Health of Sichuan University and the vice chairman of the Sichuan Association of Health Managers, first explained aerosols and their transmission: aerosols are dispersed and suspended in the air by extremely fine solid or liquid particles. The air flows together, and the particles of pathogens are directly contained in the air, which is inhaled by healthy people and causes infection.

"The transmission of new crown virus through aerosol has not been conclusive. Theoretically, aerosol transmission of new crown pneumonia is possible, but its impact on the disease epidemic is very limited." Zhang Jianxin said, "from the overall epidemic of new crown pneumonia in the country Characteristically, we have not seen evidence supporting aerosols as the main route of transmission, nor will it have an impact on current epidemic prevention and control strategies. "

Where does aerosols occur? Zhang Jianxin introduced that there are certain conditions for aerosols to be produced, and they are generally only produced in hospital ICUs due to the use of ventilators and other respiratory therapy operations. In daily life, aerosols spread even though the distance is more It stays longer in the air and stays longer in the air, but at the same time, the content of virus in aerosol is lower than that in respiratory droplets, which generally does not reach the threshold of extremely high orders of magnitude, and with environmental factors (such as temperature, sunlight, etc.) ) Changes and the passage of time, the virus in the aerosol will decrease, so the probability of propagation caused by aerosol is not great.

"At present, the transmission of the new coronavirus is still dominated by droplet transmission and contact transmission of the respiratory tract. Even if aerosol can spread, it is basically the same as the precautionary measures for droplet transmission and contact transmission, that is, 'isolation + mask + hand washing + ventilation. '.' Zhang Jianxin said.
