  On June 1, local time, the Office for National Statistics (ONS) released the country's latest "long new crown" report. As of May 1, a total of 2 million people in the United Kingdom reported "long new crown" (long Covid), accounting for 3.1% of the population.

31% of the 619,000 people who reported COVID-19 during the Omicron epidemic.

  In the previous long-term new crown report released by the Office for National Statistics on May 6, the number of long-term new crown patients in the UK was 1.8 million, that is to say, within one month, 200,000 new long-term new crown patients were added.

In the report on May 6, the number of long-term new crown patients reported during the epidemic of Omicron was 438,000, accounting for 24%.

  The ONS reported that of self-reported long-term Covid-19 patients, 442,000 (22%) were first infected (or suspected to have been) less than 12 weeks ago; 1.4 million (72%) were at least Infection 12 weeks ago; 826,000 (42%) infected at least a year ago; 376,000 (19%) infected at least two years ago.

  Among self-reported long-term COVID-19 patients, 593,000 (30%) were first infected (or suspected to be infected) before Alpha became the main mutant strain; this number was 239,000 (12%) during the Alpha epidemic and in 427,000 (21%) during the Delta epidemic and 619,000 (31%) during the Omicron epidemic.

  The survey showed that prolonged Covid-19 symptoms adversely affected the daily activities of 1.4 million people (71%), of which 39.8 (20%) reported that their ability to perform daily activities had been "significantly limited".

  Fatigue remains the most common symptom in long-term COVID-19 reports, accounting for 55%.

This was followed by shortness of breath (32%), cough (23%) and muscle pain (23%).

  UK figures show self-reported long-term Covid-19 prevalence among people aged 35 to 69, women, people living in poorer areas, people working in social care, teaching and education or healthcare and those with other restrictions A higher proportion of active health conditions or persons with disabilities.

  As more and more people around the world are infected with the new coronavirus, the "long COVID" (long-term impact of new coronary pneumonia) has also attracted more and more attention.

  The U.S. Centers for Disease Control (CDC) released a blockbuster study on May 24, local time, with a sample size of 63.4 million electronic medical records: Nearly one-fifth of adults infected with the new crown developed a "long new crown".

  According to the US CDC data, "long new 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 disease, coagulation and bleeding disorders, gastrointestinal and esophageal disorders, neurological disorders, smell and taste disorders, mood disorders, other psychiatric disorders, anxiety and fear-related disorders, sleep disorders, substance-related psychiatric disorders (Editor's note: includes abuse of alcohol, cocaine, heroin, etc.), malaise and fatigue, muscle disorders, musculoskeletal pain, type 2 diabetes, type 1 diabetes.

  The CDC used electronic health record data from March 2020 to November 2021 for people over 18 in the U.S. to assess the incidence of 26 long COVID-19 commonly attributed to COVID-19, and matched people in electronic health records who did not have COVID-19 , to compare the incidence of the two.

  The CDC said that the "long new crown" affects multiple systems: including cardiovascular, pulmonary, blood, kidney, endocrine, gastrointestinal, musculoskeletal, neurological and psychiatric signs and symptoms.

By age group, the highest risk ratio (RR) was for acute pulmonary embolism (2.1-fold increased risk relative to healthy individuals in patients aged 18-64 and 2.2-fold relative to healthy individuals in patients over 65).

Patients with other respiratory symptoms in the two age groups had a 2.1-fold increased risk relative to the healthy population.

  Since the new coronavirus Omicron variant that currently dominates the global epidemic just emerged in November last year, research on its sequelae is still in progress.

Previously, the outside world believed that "Omicron has mild symptoms and few sequelae", but Japan's preliminary results put forward different opinions.

Japan's "Mainichi Shimbun" reported on May 26 that the Tokyo Metropolitan Government announced the results of the analysis of the consultation calls on the 26th. After the new coronavirus variant strain Omicron dominated the local epidemic, the most sequelae was cough, accounting for 38.6 %, an increase of 16.4 percentage points compared with Delta and variant strains.

Fatigue and burnout accounted for 34%, an increase of 8 percentage points.

  The results released by the Tokyo Metropolitan Government showed that among the sequelae caused by the mutant strains, the more common taste and smell loss and hair loss occurred less frequently.

Specifically, taste loss accounted for 10.6% of Omicron sequelae, smell loss accounted for 9.5%, and hair loss accounted for 0.8%.

  The above analysis comes from 2,039 consultation calls received by the Tokyo Metropolitan Government from January to April this year to the Metropolitan Hospital and the six hospitals affiliated to the Tokyo Metropolitan Medical and Healthcare Corporation, with sequelae after being diagnosed with Omicron.

Among the consultation calls, 97% of confirmed cases with mild symptoms or less, 74% had no underlying disease or past medical history, and the highest proportion was 23% among those aged 40 to 49.

  He Laimanfu, the head of the expert team of the Tokyo Centers for Disease Control and Prevention, said that the people calling for consultation cover all age groups, and it has nothing to do with whether there is a previous medical history or whether it is severe at the time of the onset.

He called for infection prevention from the perspective of preventing sequelae.
