Two weeks in a row of big drops! What are the characteristics of this round of the epidemic? Severe and long COVID cases are on the rise!
On June 13, the Beijing Municipal Health Commission released the 23rd week (June 5 to June 11) epidemic, the full text of which is as follows:
Outbreak of the Week (5 June 2023 to 11 June 2023)
1. Overview of the epidemic
In the 23rd week of 2023, a total of 16,969 cases of 14 types of notifiable infectious diseases and 5 deaths were reported in the city. The top five diseases with the highest number of reported cases were: novel coronavirus infection, other infectious diarrhoeal diseases, influenza, tuberculosis and syphilis, accounting for 97.9% of the reported cases of notifiable infectious diseases.
2. Health tips for key epidemics
The number of reported cases of statutory infectious diseases in our city this week has decreased compared with last week, and respiratory infectious diseases are the main reported diseases, accounting for 94.4% of the reported diseases.
Hand, foot and mouth disease is a common infectious disease in children caused by a variety of enterovirus infections, the common age is 5 years old and below infants and young children, maintaining good hygiene habits is an important means to prevent hand, foot and mouth disease, mainly including: first, before eating, after using the toilet, after handling vomit or changing diapers should wash hands; Second, do not share towels or personal belongings with others; The third is to frequently clean and disinfect the surfaces of frequently touched items, such as furniture, toys, etc.; Fourth, vaccination with EV71 vaccine can effectively prevent hand, foot and mouth disease and other related diseases caused by EV-A71 infection.
What's new in the pandemic?
First, the number of reported cases decreased for two consecutive weeks
In the 21st, 22nd and 23rd weeks, a total of 30,750 cases, 23,526 cases and 16,969 cases of notifiable infectious diseases were reported in the city, that is, 7,224 cases and 6,557 cases were reduced in the past two weeks compared with last week!
In fact, this reduction in the number of cases is due in whole or mainly to the dramatic easing of the coronavirus pandemic!
So far, although the number of reported cases of new crowns in Beijing has been listed at the top of the list for seven consecutive weeks, it is worth noting that the number of reported statutory infectious diseases in the city in the 17th to 23rd weeks is 6438 cases, 10508 cases, 18081 cases, 25544 cases, 30750 cases, 23526 cases, and 16969 cases.
+63.22%, +72.07%, +41.28%, +20.38%, -23.49%, -28.05% month-on-month.
Since 6,312 cases of notifiable infectious diseases were reported in Beijing in the 16th week, the epidemic has increased for 5 consecutive weeks since 17 weeks, and has decreased for 2 consecutive weeks since week 22.
Second, the proportion of reported cases of the top five diseases decreased for two consecutive weeks
Another change in data is that the top 5 infectious diseases with the number of reported cases in the past 7 weeks accounted for more than 96% of the notifiable infectious diseases, and the proportion showed a continuous upward trend, from 96.0%, 97.7%, 98.4%, 98.9% to 99.0%, but decreased for two consecutive weeks in weeks 22-23, to 98.6% and 97.9% respectively.
This further confirms that the number of reported cases of the new crown has decreased for two consecutive weeks.
Third, the proportion of reported cases of respiratory infectious diseases decreased for two consecutive weeks
The proportion of respiratory statutory infectious diseases has increased for five consecutive weeks, from the 16th to the 21st week of 85.1%, 85.3%, 91.2%, 94.5%, 96.5% and 97.1%, respectively, and in the 22nd to 23rd week to 96.1% and 94.4%, respectively, that is, after five consecutive weeks of rise, it began to decline for two consecutive weeks in the 22nd week.
The new crown is the absolute main force of respiratory infectious diseases currently reported to occur, which actually indicates that the number of reported cases of new crown has decreased for two consecutive weeks!
The above three data fully prove that the epidemic situation in Beijing has dropped significantly, in fact, not only Beijing, but the epidemic situation across the country is falling sharply. The difference is that only the Beijing Municipal Health Commission in the country still insists on releasing a weekly report on the epidemic, which is really rare!
Why release epidemic information in advance?
A little surprising is that the Beijing Municipal Health Commission usually releases "This Week's Epidemic" every 7 days, that is, every Wednesday, before that, it has been reported on Wednesday for 5 consecutive weeks, but this time it was released on Tuesday, probably because the epidemic is declining, I want to let everyone know the good news earlier!
So what are the characteristics of this round of the epidemic?
The author believes that compared with the first wave of rapid upward rush and rapid decline at the end of last year and the beginning of this year, the biggest feature of this round of the epidemic is that the epidemic develops slowly and the infection rate is not high. The epidemic gradually started around the "May Day" festival, and was at a high platform (about 15-20 days) from May 15 to June 5, of which it reached its peak around May 25, began to decline significantly around June 6, and quickly descended to the halfway up the mountain, and is currently hovering halfway up the mountain and has lasted for about 10 days.
The second characteristic is that as the epidemic eases, severe cases and long new crown cases have increased. Hu Yang, deputy chief physician of Shanghai Pulmonary Hospital, posted on the evening of June 14 in "Today's Headlines" that the number of new patients is reduced than before, but it is still continuous, and many people come to see the symptoms of the new crown, and even the wave of infected patients at the end of December, have been coughing or chest tightness until now, some of them did not have asthma before, and asthma was detected after infection, which is not that the virus will cause asthma, but the symptoms that were not so serious before were amplified.
He wrote that the number of critically ill patients has increased compared with before, because the number of new crown patients in the ward has begun to increase, the treatment has improved and discharged a wave, and immediately there is another wave on top, some non-new crown patients complain about why they live together, in fact, after Class B tube this is the norm, it is impossible to isolate all the time, besides, the society has been released, the ward isolation is meaningless, where is not the same to be infected, although I don't want someone to be infected, I don't want to become severe after infection, but it is really unavoidable.
At present, the number of reported cases of new coronavirus infection has been at the top of the list for 7 consecutive weeks.
