    Written | Edited by Wang Cong | Typesetting by Wang Duoyu | Shui Chengwen Recently, there has been a small-scale new crown epidemic in China
    .

    According to data from the National Health and Medical Commission, since March 1, more than 56,000 local infections have been reported nationwide, affecting 28 provinces, among which Jilin and Shanghai are more prominent
    .

    Most of the infected people in this round of domestic new crown epidemic are asymptomatic, but Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and Prevention, recently said that the fatality rate caused by the mutant strain of Omicron has indeed decreased, but the total number of deaths caused by it is higher than that of Del Number of deaths during the same period in which tower mutants were prevalent
    .

    Therefore, the harm of Omicron is still serious, and the new crown pneumonia is not a "big flu"
    .

    Most people infected with the new crown will only have mild symptoms or even no symptoms
    .

    But the probability of post-infection severity varies for people of different ages and genders
    .

    Older people have a higher rate of severe illness than younger people, and men have a higher rate of severe illness than women
    .

    A study published recently shows that a person's finger length and proportions can be used as predictors of the severity of his new crown infection
    .

    It is generally accepted that a longer ring finger is a marker of prenatal exposure to higher levels of androgens (testosterone), while a longer index finger is a marker of higher levels of estrogen
    .

    In general, men's ring fingers are longer than their index fingers, while women's index fingers are longer than their ring fingers
    .

    Left picture: The ring finger is longer than the index finger; Right picture: The index finger is longer than the ring finger.
    Because the severity of infection with the new crown is closely related to gender (the proportion of severe cases in men is higher), the research team began to study the androgen testosterone.
    The relationship between the severity of post-COVID-19 infection
    .

    Recently, researchers from the Medical University of Lodz in Poland, Swansea University in the United Kingdom, and Karolinska University Hospital in Sweden collaborated to publish a paper entitled: Digit ratios and their asymmetries as risk factors of developmental instability and hospitalization for the journal Scientific Reports.
    Research paper on COVID-19
    .

    The research team took a closer look at the ratio of the lengths of people's four fingers (index, middle, ring, and little fingers) other than the thumb as a predictor of the severity of COVID-19 infection
    .

    The study's collaborator, Professor John Manning, has found in previous research that children's finger length and proportions are related to their mothers' income, noting that hormones a person is exposed to in the womb before birth can affect future susceptibility to disease
    .

    Low-income mothers may “feminize” their children through hormonal influence (index fingers are longer than ring fingers, and prenatal exposure to androgens is low and estrogen levels are high), while high-income mothers “masculine” their children (The ring finger is longer than the index finger and is exposed to high androgen levels and low estrogen levels before birth)
    .

    They argue that this is an evolutionary strategy that helps boost fertility in offspring (because sons from low-income families are less likely to have reproductive opportunities)
    .

    In the new study, the team found that those with a smaller ratio of pinky to other fingers tended to have severe symptoms and hospitalization after contracting Covid-19
    .

    Those with large differences in the ratio of index finger/ring finger length and middle finger/little finger length ratio between the left and right hands have a greatly increased risk of developing severe symptoms after the new crown before infection
    .

    Research suggests that this is a combination of prenatal hormonal exposure in utero (ratio of finger length) and hormonal influence during puberty (asymmetry of left and right hand development)
    .

    Index finger (2D), middle finger (3D), ring finger (4D), little finger (5D) The team said the results of this study showed that the severity of infection with the new coronavirus was associated with low testosterone and high estrogen in both men and women
    .

    The situation of hospitalized patients with Covid-19 also supports the idea that individuals who have experienced low testosterone and/or high estrogen are more likely to develop severe disease, which explains why older men are a high-risk group for Covid-19
    .

    The research team further noted that the study's ability to predict who is more likely to develop severe disease after contracting the new coronavirus could aid in targeted vaccinations to help those at higher risk
    .

    It also helps us improve anti-coronavirus drugs to help shorten hospital stays and reduce mortality
    .

    The research team said that the sample in the paper is not yet large, and research is continuing to further expand the sample size to provide more accurate predictors
