Today (20th), The Joint Prevention and Control Mechanism of the State Council held a press conference to introduce the situation of medical services for key groups.
China Disease Control: BQ.1 and XBB have not yet formed an advantage in spreading in China
The Joint Prevention and Control Mechanism of the State Council held a press conference on December 20, at which Xu Wenbo, director of the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, stated that BQ.1 and XBB are new mutant branches of Omicron. Internationally, some European and American countries have gradually shown that they are dominant strains, mainly manifested by increased transmissibility and immune evasion capabilities. However, its pathogenicity is not significantly different from other series of mutant strains of , Omicron, , and the severe disease rate and mortality rate have not increased significantly in these countries where BQ.1 and XBB are prevalent.

Xu Wenbo said that in fact, BQ.1 and XBB have been introduced into our country. In the past three months, our country has monitored the introduction of BF.7, BQ.1, and XBB into our country, with a total of 130 Multiple subclades of Omicron were imported into my country, and these 50 subclades caused associated local cases or outbreaks, including BQ.1 and XBB. Among them, BQ.1 and its subclades were detected in 49 cases in 9 provinces, and the XBB subclade was detected in 11 cases in 3 provinces. The entire BQ.1 and XBB have not yet formed a dominant spread in my country (currently BA.5.2 and BF.7 are still the main ones), but their spread advantage will gradually increase, and BA.5.2 and BF.7, as well as more than 50 other input sub-branches, may form a common cycle.
's prevention of BQ.1 and XBB is actually the same as other Omicron mutant strains. "The measures we take are to monitor whether its pathogenicity has changed and whether its genome has further mutated. If there are any changes in its clinical characteristics, we will link it with the genomic characteristics for research and judgment. However, it has not yet been found that BQ.1 and XBB cause an increase in severe illness and death at home and abroad. Added report. Prevention must be done well, we are the first responsible for our own health. "
Regarding "vaccination is not as good as being infected with Omicron"
Some people think that because Omicron is more asymptomatic and the antibodies obtained by infection are more effective than vaccination in preventing reinfection, it is believed that vaccination is not as good as being infected with Omicron, especially for young people.
In this regard, Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, said: Although the pathogenicity of the currently circulating Omicron strain is somewhat weakened compared with other mutant strains that have been popular in the past, there is still a risk of severe illness and death; and the risk of severe illness and death is reflected in all age groups. "It's just that the risk of severe illness and death among the elderly that we emphasized in the past will be higher among the entire population. In addition, the proportion of people with underlying diseases will also be higher."
Wang Huaqing said that many studies have shown that compared with people who have completed the full course or strengthened immunity new coronavirus vaccine, the risk of hospitalization, severe illness and death of people who have not been vaccinated is quite different, including young people and adults. Where this risk exists to some extent, it can be reduced through vaccination.
About infant antipyretic
Regarding the problem of infants and young children being infected with new crown , experts said that the only antipyretic drug available for children over 2 months old and under 6 months old is acetaminophen . Children under 2 months old cannot take oral antipyretic drugs. It is recommended that babies under 2 months old, including newborns, should be sent to the hospital in time once they have a fever.
It is not recommended for infants to reduce fever by covering their sweat. In the case of sweating, the body temperature of infants and young children may become higher and higher, and some children may develop severe sweating syndrome, which may lead to serious complications such as respiratory failure, dehydration, and neurological damage, and may even be life-threatening.
About the new coronavirus specific drugs
The ninth edition of the diagnosis and treatment plan recommends several antiviral drugs. Early use of these antiviral drugs may reduce the occurrence of severe illness, shorten the course of the disease, and shorten the detoxification time of virus , but they need to be used under the guidance of a doctor.
How do you think about the saying "morning is good in the morning"
Experts said that although Omicron is highly contagious and most infections are self-limiting, with low pathogenicity or severity, we do not advocate or recommend intentional infection.
First of all, although the pathogenicity of Omicron has decreased significantly, some patients still develop clinical symptoms after infection, which will seriously affect the quality of life and normal work.
Secondly, we hope that there will not be a large number of outbreaks in a short period of time, so as not to cause a rush and affect the daily treatment of critical and severe patients in medical institutions.
About "recovery positive"
From the perspective of "recovery positive" incidence rate, the original strain in the past had a "recovery positive" rate of 5% to 15%. At present, the "recovery positive" rate of the Omicron strain has not increased overall.
Regarding the harmfulness and contagiousness issues after "re-positive", experts said that "re-positive" is a relatively common situation of new coronavirus infection, and the infectivity is extremely low, so there is no need to panic.
Regarding the criteria for determining death from the new coronavirus
Experts said that after infection with the Omicron strain, the main cause of death is underlying diseases, and very few people die directly from the new coronavirus infection.
mainly judges death cases from two aspects: deaths caused by pneumonia and respiratory failure caused by the new coronavirus are classified as deaths caused by new coronavirus infection; deaths caused by other diseases and basic diseases, such as cardiovascular and cerebrovascular diseases, , myocardial infarction, etc. are not classified as deaths caused by the new coronavirus.
In order to better standardize the statistics of deaths caused by the COVID-19 epidemic, consultation and death discussions must be adopted to finally determine whether the patient died of COVID-19 or other underlying diseases. We do not avoid the dangers of COVID-19, but we must also treat the dangers of COVID-19 scientifically.
