On June 1 local time, the office for National Statistics (ONS) of the UK released the country's latest "long new crown" report. As of May 1, a total of 2million people in the UK reported "long covid", accounting for 3.1% of the population. During the epidemic period of Omicron, 619000 people reported the new crown, accounting for 31%**
In the previous long new crown report released by the National Bureau of statistics on May 6, the number of patients with long new crown in the UK was 1.8 million, that is to say, 200000 new long new crown patients were added within one month. In the report on May 6, 438000 changxinguan patients were reported during the epidemic period of Omicron, accounting for 24%.
The office for national statistics reported that 442000 (22%) of the self-reported changxinguan patients were first infected (or suspected to have been infected) less than 12 weeks ago; 1.4 million people (72%) were infected at least 12 weeks ago; 826000 people (42%) were infected at least one year ago; 376000 people (19%) were infected with the new crown at least two years ago.
Among the self-reported changxinguan patients, 593000 (30%) were first infected (or suspected to be infected) before alpha became the main variant strain; This figure was 239000 (12%) during the alpha epidemic, 427000 (21%) during the delta epidemic and 619000 (31%) during the Omicron epidemic.
The survey showed that the symptoms of changxinguan had an adverse impact on the daily activities of 1.4 million people (71%), of which 39.8 people (20%) reported that their ability to carry out daily activities had been "greatly limited".
Fatigue is still the most common symptom in the report of changxinguan, accounting for 55%. Followed by shortness of breath (32%), cough (23%) and muscle pain (23%).
Data from the UK show that the self-reported prevalence rate of changxinguan is higher among people aged 35 to 69, women, people living in poorer areas, people engaged in social care, teaching and education or health care, and those with other restricted activities or the disabled.
As more and more people around the world are infected with novel coronavirus, "long covid" (long-term impact of COVID-19) has also attracted more and more attention.
On May 24, local time, the Centers for Disease Control and Prevention (CDC) of the United States released a massive study with a sample size of 63.4 million electronic medical records: nearly one fifth of adults infected with new crowns have "new crowns".
According to the data of CDC in the United States, "Changxin crown" includes 26 common problems: acute myocardial infarction, arrhythmia, cardiovascular disease, heart failure, myocarditis and cardiomyopathy, acute pulmonary embolism, respiratory symptoms, asthma, renal failure, chronic kidney disease, thromboembolic events, cerebrovascular diseases, coagulation and hemorrhagic diseases, gastrointestinal and esophageal diseases, nervous system diseases, smell and taste disorders, mood disorders Other mental diseases, anxiety and fear related diseases, sleep disorders, substance related mental diseases (Note: including alcohol abuse, cocaine, heroin, etc.), discomfort and fatigue, muscle diseases, musculoskeletal pain, type 2 diabetes, type 1 diabetes.
CDC in the United States used the electronic health record data of people over 18 years of age in the United States from March 2020 to November 2021 to evaluate the incidence of 26 long covids usually attributed to new crowns, matched the population who had not been infected with new crowns in the electronic health record, and compared the incidence rate of the two.
According to CDC of the United States, "changxinguan" affects multiple systems: signs and symptoms of cardiovascular, pulmonary, blood, kidney, endocrine, gastrointestinal, musculoskeletal, neurological and mental. By age group, the highest risk ratio (RR) is acute pulmonary embolism (the relative risk of patients aged 18-64 years is 2.1 times higher than that of healthy people, and the relative risk of patients aged 65 years or older is 2.2 times higher than that of healthy people). The risk of other respiratory symptoms in the two age groups was 2.1 times higher than that in the healthy population.
The Omicron variant of novel coronavirus, which currently dominates the global epidemic, was just emerging in November last year, and its sequelae research is still in progress. Previously, the outside world believed that "Omicron had mild symptoms and few sequelae", and Japan's preliminary results put forward different opinions. According to the report of Japan's daily news on May 26, Tokyo released the analysis results of the consultation telephone on May 26. After the local epidemic was dominated by the new crown variant strain Omicron, the most sequelae was cough, accounting for 38.6%, an increase of 16.4% compared with Delta and the variant strain. Fatigue accounted for 34%, an increase of 8 percentage points.
The results released in Tokyo showed that the frequency of taste and smell failure and hair loss, which were common among the sequelae caused by the previous mutant strains, decreased. Specifically, in Omicron's sequelae, taste failure accounted for 10.6%, smell failure accounted for 9.5%, and hair loss accounted for 0.8%.
The above analysis comes from 2039 consultation calls received from Tokyo dududuli hospital and the six hospitals affiliated to Tokyo Medical and health care commune from January to April this year, which were diagnosed with sequelae after infection with Omicron. Among the consultation calls, 97% of the patients were diagnosed with mild illness or below, 74% had no basic disease or previous medical history, and the highest proportion was between 40 and 49 years old, reaching 23%.
Helai Manfu, head of the expert group of the Tokyo Center for Disease Control and prevention, said that the people who called for consultation covered all ages and had nothing to do with whether they had a past medical history or whether they were seriously ill at the time of onset. He called for infection prevention from the perspective of preventing sequelae.
