    On April 1, the Joint Prevention and Control Mechanism of the State Council held a press conference to introduce the situation related to the strict and earnest efforts to prevent and control the epidemic
    .

    Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said that the epidemic of the Omicron strain is still very harmful to a country or region.
    zero"
    .

    Wu Zunyou said that although the Omicron BA.
    2.
    strain had a high proportion of asymptomatic infections, due to its rapid spread, a large number of infected people would be produced in a short period of time, and the total number of deaths was still very high
    .

    By analyzing the data released by some foreign countries, it can be seen that the number of deaths caused by the Omicron strain during the epidemic is higher than that caused by the Delta strain during the same period
    .

    Source: This passage on the Chinese Internet has caused a great impact! It makes people feel that the harm of Omicron is far greater than that of Delta.
    In fact, the following facts in Wu Zunyou's words are ignored! 1.
    "In the same period" In fact, the fatality rate caused by Delta is much higher than that of Omicron
    .

    However, when Omicron broke out, the number of infections in the short term was indeed higher than that of Delta
    .

    Therefore, in a very short period of time, there may be a phenomenon that "the number of deaths caused by Omicron is higher than the number of deaths caused by Delta"
    .

    In fact, tracing the original text, this sentence was reported by the Wall Street Journal on January 17, 2022, see: Deaths Due to Omicron Higher Than From Delta (webmd.
    com) This week the nation recorded a seven-day average of 2,200 daily coronavirus-related deaths , higher than the daily death count recorded two months ago during the Delta variant surge, The Wall Street Journal reported.
    Meaning, in the U.
    S.
    , based on the seven-day average of deaths in a week at the time of reporting, Omikron caused the daily death count The 2,200 deaths were higher than the daily average recorded two months ago when Delta was popular
    .

    However, the professional medical organization WebMD cites a CDC article to explain further: A CDC study released on Tuesday showed nine deaths per 1,000 cases during the Omicron surge, compared to 13 deaths per 1,000 cases during the Delta surge and 16 deaths per 1,000 cases during last winter's deadly surge.
    Meaning, 9 deaths per 1000 people during the Omicron epidemic and 13 deaths per 1000 people during the Delta epidemic
    .

    And in the original winter (Winter 2020), there were 16 deaths per 1,000 people
    .

    That is to say, from the perspective of the fatality rate, Omicron is lower than Delta
    .

    And the Walensky expert in the article further emphasized that many of the deaths were caused by incomplete vaccination
    .

    2.
    "Some foreign countries" Wu Zunyou emphasized in his speech that the data analyzed came from "some foreign countries"
    .

    It means that the death toll caused by Omicron is higher than that of Delta, only in some countries
    .

    However, when the media reports, many omit "some foreign countries", causing people to misunderstand
    .

    In the United States, the number of deaths caused by Omicron over the same period is indeed higher than that of Delta (the last two waves, Delta is the second-to-last curve, and Omicron is the last)
    .

    At the peak of Omikojon on January 25, 2022, the average seven-day death toll in the United States was 2,230, while Delta was only 2,100 (in September 2021)
    .

    But both are well below January 2021 (when the vaccine is not widely available)
    .

    The trend of the death toll of the new crown in the United States The trend of the death toll in many countries around the world 3.
    The historical discovery of the global overall data observation of Delta, the virus strain was first discovered in India in October 2020
    .

    In May 2021, the WHO named the new coronavirus variant B.
    1.
    617.
    2, which was first discovered in India, as the "Delta" variant
    .

    The variant was identified as one of the drivers of India's second wave of the outbreak
    .

    It was reported on June 15, 2021 that the "delta" variant was further mutated to derive the "delta+" or "AY.
    1" variant
    .

    On July 2, WHO held a regular press conference on new coronary pneumonia.
    WHO Director-General Tedros Adhanom Ghebreyesus said that the delta variant is becoming the main epidemic strain in many countries
    .

    Since then, delta mutants have appeared in at least 98 countries and regions, and continue to mutate and evolve
    .

    Since the change of virus strains is stubble, if July 2021 is calculated as Delta becoming the main epidemic strain (in fact, it is much earlier than July), its epidemic will last until December 2021 (the Austrian Micron), the graph below is the global total death toll curve
    .

    The green part is dominated by deaths caused by Delta, and the red part is dominated by deaths caused by Omicron
    .

    In fact, many deaths caused by Delta infections are also in the red line, because of the lag of deaths
    .

    Of the points where we do see the highest peak, Omicron is higher than Delta, and just comparing the peaks, it seems that Omicron is higher than Delta
    .

    However, the duration of Omicron is generally only 2 months.
    In addition to the overall epidemic situation, the duration of death is 4 months; while Delta lasts longer, and it takes 4-5 months from peak to fall in a country.
    , Globally, it has been popular for nearly 7 months (May to the end of November) with the replacement of Omicron
    .

    If time is counted, it is assumed that the total number of deaths caused by Delta is greater than that of Omicron
    .

    The director of the US CDC wrote this: Compared with Delta, Omicron has a 53% reduction in the risk of symptomatic hospitalization, a 74% reduction in the risk of ICU, and a 91% reduction in the risk of death
    .

    This is an objective evaluation
    .

    Of course, Omikron cannot be completely ignored
    .

    The risk remains high for the elderly and those with multiple underlying comorbidities
    .

    1.
    The outbreak of Omicron is very fast.
    As far as the current situation is concerned, the spread of Omicron is much faster than that of the previously dominant delta variant - research shows that the former spreads faster than the latter.
    four times
    .

     In the U.
    S.
    , most people who died in Omikron were not vaccinated, suggesting that vaccines played a role in reducing hospitalizations and deaths
    .

    2.
    Omicron Less serious but "not gentle" Dr.
    Maria Van Kerkhove of the World Health Organization, in a video explaining the effects of the Omicron variant, said there is growing information that Omicron does not have Del Ta virus is so serious, but don't treat the Omicron Covid-19 variant as a mild strain
    .

    Van Kerkhov pointed out that elderly people, people with underlying diseases, and people who have not been vaccinated are still at risk of developing severe disease after contracting Omicron
    .

    "We know that people infected with Omicron may still develop a full range of disease, from asymptomatic infection to mild disease, all the way to severe disease, and even death
    .

    " 3.
    The burden on the medical system increases as Omic The surge in cases in December and January has hospitals around the world struggling to cope with the number of admissions
    .

    Under the weight of cases, a crumbling healthcare system will inevitably find it harder to save lives
    .

    As highlighted by WHO's Dr.
    Van Kerkhove, an increase in Omicron's transmission will lead to more hospitalizations, placing a burden on the healthcare system
    .

    "If the healthcare system is overburdened, then people will die
    .

    We have to be very careful not to let the outside world think Omicron is a mild disease ," she noted
    .

    4.
    What can we do to protect ourselves Van Kerkhove Besides vaccination, other measures are still needed to reduce transmission and disease,
    Dr.

    "Vaccination, which has a strong effect on preventing severe illness and death, is not very effective in preventing infection and further spread
    .

    " "That's why we still advise people to protect themselves and avoid exposure to the virus.

    .
    Keep
    social distance, wear a mask, keep your hands clean, avoid crowding, work from home where possible, get tested for Covid-19, seek medical care if needed.
    .
    .
    all of these measures can protect you from infection, prevent Spread the virus to others
    .

    " 5.
    Reduce the risk of future mutations The more widely the virus spreads, the more chance it will mutate, says Dr.
    Van Kerkhove
    .

    Therefore, another reason to take protective measures is to reduce the risk of further mutations in the virus that would otherwise prolong the pandemic and lead to more deaths
    .

    "Omicron will not be the last variant
    .

    The possibility of more worrying variants in the future is very high, and we have yet to discover the possible properties of these variants ," she stressed
    .

    "Of course, the new Variants may be more transmissible because they need to outperform what is currently circulating
    .

    It may not necessarily be less virulent, it may be more or less enhanced, and at the same time have more immune escape properties
    .

    So what we do, It is to reduce the risk of new variants appearing in the future
    .

    " In summary, according to the domestic perspective, adhere to the "three-piece set" of epidemic prevention, and keep in mind the "five requirements" for protection
