The recent outbreak in Tianjin has attracted the attention of many friends, one of the reasons is that the relevant news shows that the strain that caused the epidemic is a new type of "Omi Kerong mutant strain", which is also the first "head-on duel" between Chinese mainland and Omilon.
After rapid investigation, Tianjin has found 31 confirmed cases in two days, and 10 cases of asymptomatic infection, from the current situation, due to the early stage of the newly discovered epidemic, whether the epidemic has further spread and spillover, further investigation and time verification is needed, and according to the latest news from Tianjin Cdron, because Aomi Kerong also has the characteristics of human-to-human transmission and transmission through goods and the environment, although the traceability of the virus has made some progress, it is still not clear. As soon as possible to find out the source of the epidemic and the nucleic acid testing of all employees, it is being carried out in an orderly manner from two aspects, and I believe that we will have the ability to quickly control the epidemic. #天津疾控: The source of this round of the epidemic is very unclear #
Some careful friends also found that in this Tianjin epidemic, unlike in the past, among the infected people who were found positive, primary and secondary school students accounted for more than 50%, and in this case, is the risk of infection of children in Omi Kerong greater? And what are the characteristics of children infected with the Aomi Kerong virus strain? Today we're going to talk about children and the Aomikron mutant.
The increase in childhood infection with the Omiljung virus is closely related to 3 causes
In the Tianjin epidemic caused by Aomi Kerong, the proportion of infections in children is relatively high, and there are certain objective reasons for the occurrence of this situation, but if we carefully analyze a variety of factors, such a situation is closely related to the following three reasons.
First of all, the Omiljunn variant itself is super infectious, from November 26, the new type of Omilcroon variant was defined by WHO as a "concerned variant", to the wide spread of Omikeron worldwide, it took less than 1 month, and from the analysis of the characteristics of virus variation, Omiljung showed stronger infectious characteristics than the original dominant strain Delta, and the risk of breakthrough infection and re-infection is also higher. Therefore, if this variant with super transmission ability appears, whether it is for adults or children, the risk of infection will be relatively large.
Second, the clustering of children and adolescents also increases the risk of virus transmission. Most of the children infected with the epidemic in Tianjin are primary and secondary school students, and there is a clear relationship with the transmission formed in the custodial institutions, children have to go to school every day, and the probability of contact with other children in the class and custodial institutions is greatly increased, which is stronger than that of adults, so the risk of clustered cases is higher, from the current epidemic situation in Tianjin, it is centered on the custodial institutions, which has spread to 3 primary and secondary schools, and the high risk of explosive transmission in the school is also worthy of special attention.
Third, in addition to the above two reasons, should also consider the impact of vaccination rates, in the process of continuous promotion of vaccination for the whole population, the current vaccination of adolescents over 12 years old has been more than 90%, but the vaccination of children aged 6 to 12 years old, is underway, although the Omiljung variant will still lead to breakthrough infections in the vaccinated population, but the lack of vaccine protection for children, the risk of infection with the virus will be further increased, relevant research proves that the antibodies produced in the body of the vaccinated population, Although it has a weaker role in reducing Omiljung infection, it can still play an effective role in preventing severe disease.
The above 3 reasons have led to the possibility of children infected with the Aumechjong variant, and throughout the world epidemic, the number of children infected with the Aomi kerong strain in the United States has also risen sharply recently, relevant experts pointed out that this is closely related to the relatively low vaccination rate of children in the United States, while the increasing number of adult infected people around them, and in the United Kingdom and France and other countries, the impact of Omikejong on children has also attracted the attention of doctors and the public.
Therefore, for the situation that the proportion of children infected with the Aomi Kerong variant in the Tianjin epidemic is high, it is actually a high-probability event that occurs under the wide spread of Aomi Kerong around the world, and at the same time, it is closely related to the place where the virus occurs, the characteristics of the virus, and the characteristics of children and adolescents, I believe that with the continuous deepening of the investigation work, the transmission chain of Aomi Kerong in children will be gradually controlled.
Children infected with the Omiljung virus, 2 "unusual" symptoms are worth noting
Our cumulative number of cases is very limited, for the relevant clinical data of children infected with Omikejong is currently small, but foreign medical institutions have also made relevant assessments and judgments on the relevant situation of Omikejong infected children, for children infected with Omikejong, fever, hoarseness, sore throat, fatigue, loss of appetite and other symptoms are similar to the symptoms of infection with other new coronavirus variants, but in addition, pediatricians from britain and the United States have also proposed two "new symptoms".
The first symptom is called "whewing," said Dr. Krich, an infectious disease expert in the United States, who and his colleagues noticed that many children infected with the Omiljung strain, especially those under the age of 5, would experience "crook-like manifestations." This croup is actually a coughing symptom accompanied by a severe asthmatic sound that sounds like a "bark of a dog or a seal," which is actually a form of inflammation and swelling of a child's upper respiratory tract, a blockage, Dr. Krich noted, "Children's airways are very narrow, so much less inflammation is needed to block them." Therefore, croup and bronchiolitis should be one of the notable symptoms of childhood infection with the Omikejong variant.
The second symptom is a peculiar rash, which comes from a report by a General Practitioner in London. According to US media reports, Dr David Lloyd, a general practitioner from north London, said that about 15% of children infected with the Omikejong variant had an unusual rash, while he also stressed that in addition to the rash, the difference in symptoms from different people is more noteworthy.
For the above two symptoms, although it is some of the "new symptoms" that may appear after the Infection of Children by Aomi Kerong, but for parents, do not worry too much, such symptoms may also be caused by other diseases, seasonal influenza, respiratory syncytial virus infection, etc., may cause wheezing symptoms, and allergies and other issues, may also cause children to appear rash, so if children have fever symptoms, timely medical treatment and nucleic acid testing is a better and accurate way to find problems in time It is more important to improve treatment in a timely manner.
