在至少18个州，女性比男性占新冠状病毒病例的比例更高，但男性占死亡病例的比例更高新闻周刊州人口统计信息显示。

各国已经开始收集和公布关于谁感染了COVID-19的信息，但这些数据没有以统一的方式呈现。新闻周刊审查发现，28个州提供了按性别分列的病例和死亡数据，37个州公布了病例和死亡的年龄信息。

在那些按性别公布病例的州中，有18个州报告称，截至5月4日，更多的女性感染了冠状病毒，但更多的男性因此死亡。

只有一个州，堪萨斯州，男性病例更多，而女性死亡人数更多。俄亥俄州、南达科他州、田纳西州和得克萨斯州这四个州的男性病例和死亡人数都有所增加。在罗德岛州，据报道有更多的妇女感染了这种病毒，但据报道男女都死于这种病毒，而在加利福尼亚，男女病例几乎相等，但大多数死亡病例都是男性。

尚不清楚为什么越来越多的女性在冠状病毒病例中所占的比例越来越大，但当局称这可能是因为她们接受的检测越来越多。在4月9日的白宫简报会上，黛博拉·比克斯博士指出，美国56%接受检测的人是女性，但当时女性检测呈阳性的比例低于男性。

正如Birx建议的那样，女性可能不像男性那样不愿意接受检测，但专家们表示，他们认为男性患严重并发症的风险更大，这可能是各州报告男性死亡率较高的原因。

哥伦比亚大学微生物学和免疫学教授文森特·拉卡尼洛告诉记者新闻周刊男性有不同的共病，可能会影响病毒对他们造成的伤害，导致更多的死亡。男性和女性之间的激素差异也可能是导致病例和死亡的原因。

然而，如果不知道感染和死于该病毒的男性和女性的其他特征，就很难知道数据背后确切的“为什么”。但是，有一天我们应该能够得出这些结论，这将是“有趣的发现”，拉卡尼洛说。

在爆发疫情的中国，男性的死亡率更高，约翰·霍普金斯妇女健康、性别和性别差异中心的研究员萨布拉·克莱因上个月告诉NPR，这一趋势也在西班牙复制。根据西班牙卫生部周一的一份报告，在西班牙，女性病例比男性多，但男性死亡人数更多。

根据约翰·霍普金斯大学维护的追踪系统，截至周三，美国已有超过120万人被证实患有新的冠状病毒，71526人死亡。据估计，美国有189，791人被认为已经康复。

周一在纽约市，冠状病毒大流行期间，女性戴着面罩走路。在公布病例和死亡人口统计信息的州中，有18个州发现了更多的女性病例，但男性死亡人数更多。

新闻周刊对数据的审查显示，37个州明确提供了病例和死亡年龄的人口统计数据。在这37个州中，他们都报告说，他们的大多数案件涉及65岁以下的人，他们的大多数死亡涉及至少65岁的人。

乔治华盛顿大学流行病学副教授安妮·门罗博士告诉记者新闻周刊年轻人群可能占更多病例，因为他们是劳动人口的一部分。基本工人和卫生保健领域的人员大多属于65岁以下的人群。

12个州报告说，在50至59岁的人群中发现的病例数量最多。在密苏里州，65岁至69岁之间的人患病人数最多，在俄克拉荷马州，60岁以上年龄段的人患病人数最多。

在提供死亡和病例年龄分类的37个州中，18个州报告的死亡人数最多的是80岁以上的人。威斯康星州是报告死亡人数最多的州，90岁以上的人最多。

关于这种新冠状病毒的一个信息焦点是老年人更容易患上严重疾病，拉卡尼洛说，他对数据显示死亡主要发生在老年人身上并不感到惊讶。随着年龄的增长，免疫系统的问题会增加，所以在大多数情况下，感染了病毒的年轻人往往会有较轻的病例。拉卡尼耶洛说，很难说为什么各州在50岁至59岁的人群中发现了大量病例，但他推测他们可能工作时间更长，因此增加了暴露的机会。

门罗指出，如果不能比较不同年龄段人群的病例分布，就很难知道某个人群是否受到了过度影响，或者该年龄段人群的比例是否更高。年龄在50岁到59岁之间的人也有可能有更严重的症状，因此比年轻人接受更多的检测，年轻人可能有非常轻微的病例。

“我们只知道冰山一角，因为到目前为止的测试模式，”门罗说。“因此，很少有人可能已经被感染并接受了检测，了解谁将接受检测对所有这些都很重要。”

HOW CORONAVIRUS CASES, DEATHS DIFFER BETWEEN MEN AND WOMEN BY STATE

In at least 18 states, women account for a higher percentage of cases of a new coronavirus than men, but men make up a greater percentage of the fatalities, a Newsweek review of state demographic information showed.

States have begun to collect and publish information about who has contracted COVID-19, but the data is not presented in a uniform way. Newsweek's review found that 28 states made data available for cases and death by sex and 37 published age information for cases and deaths.

Of those that published cases by sex, 18 states reported that as of May 4, more women were infected by the coronavirus, but more men had died from it.

Only one state, Kansas, had more cases among men but more deaths among women. Four states–Ohio, South Dakota, Tennessee and Texas–have had more cases and deaths involving men. In Rhode Island, more women were reported as having the virus, but both sexes were reportedly equally as having died from it, whereas in California, there were nearly equal cases among men and women but a majority of deaths involving men.

It is not clear why more women appear to account for a larger percentage of coronavirus cases, but authorities have said it is possibly because they're getting tested more. During an April 9 White House briefing, Dr. Deborah Birx noted that 56 percent of people in the country who were tested were female, but a smaller percentage of women were testing positive at the time than men.

While women may be less reluctant to get tested than men, as Birx suggested, experts said they believed men may be at a greater risk for serious complications, which may account for why states are reporting higher deaths among men.

Vincent Racaniello, a professor of microbiology and immunology at Columbia University, told Newsweek that men have different comorbidities that could influence the toll the virus takes on them, leading to more deaths. It's also possible hormone differences between men and women could be contributing to the levels of cases and deaths.

However, without knowing the other characteristics of the men and women who are contracting and dying of the virus it's hard to know the definitive "why" behind the data. But, one day we should be able to draw those conclusions and it will be "interesting to see," according to Racaniello.

There was a higher fatality rate among men in China, where the outbreak originated, and Sabra Klein, a researcher at the Johns Hopkins Center for Women's Health, Sex, and Gender Differences told NPR last month that the trend was replicated in Spain, as well. Women accounted for more cases than men in Spain, but more men had died, according to a Monday report by the country's Ministry of Health.

As of Wednesday, more than 1.2 million people in America were confirmed to have a new coronavirus and 71,526 people died, according to a tracker maintained by Johns Hopkins University. An estimated 189,791 people in America have been deemed recovered.

Newsweek's review of the data showed that 37 states clearly provided demographic data about ages for both cases and deaths. Of those 37 states, they all reported a majority of their cases involved people who were under 65 years old and the majority of their deaths involved people who were at least 65 years old.

Dr. Anne Monroe, an associate research professor of epidemiology at George Washington University, told Newsweek younger populations accounting for more cases is likely because they're part of the working population. Essential workers and those in the health care fields would mostly fall into the category of people under 65-years-old.

Twelve states reported their highest number of cases were identified among people from 50 to 59 years old. In Missouri, people between the ages of 65 and 69 had the highest number of cases and in Oklahoma, those in the age bracket of being over 60 years old had the most cases of any age bracket.

Of the 37 states that provided age breakdowns for both deaths and cases, 18 reported their highest number of deaths involved people over the age of 80. One state–Wisconsin–reported the most deaths with people over 90.

A focal point of messaging about the new coronavirus has been that elderly populations will be more susceptible to developing serious disease and Racaniello said he wasn't surprised data showed deaths were predominately in older people. Immune system problems increase as a person ages, so for the most part, younger people who have contracted the virus tend to have milder cases. It's hard to say why states saw a larger number of cases among 50- to 59-year-olds, according to Racaniello, but he speculated it's possible they were working longer, therefore increasing the chances they were exposed.

Monroe noted that without being able to compare the distribution of cases among age brackets to the population, it's hard to know if a demographic is being disproportionately affected or if there's just a higher population of that age group. It's also possible that people who are between the ages of 50 and 59 have more severe symptoms and therefore are being tested more than younger people, who may have a very mild case.

"We only know about the tip of the iceberg because of the patterns of testing so far," Monroe said. "So few people who may have been infected have gotten tested and understanding who is presenting for testing is important for all of this too."
