As Covid 19th pandemic takes its toll ever-larger worldwide, researchers broaden their understanding of who is at greatest risk of infection, serious illness, and deaths, detailed information has previously been reported only in China, where the outbreak began late last year.

In general, the US experience largely emulate China, with the risk of serious illness and death from Covid-19 rose with age. But in an important qualification, a report on Wednesday underlined the message that infectious disease experts have emphasized: the millennium. The new data show that up to one-fifth of infected people ages 20-44 have been hospitalized, including a 2% -4% required treatment in the intensive care unit.

However, most cases are severe, and the highest death rate among the elderly. Although 17% of the US population is 65 or older, 31% of the cases were in the age group, CDC experts concluded in the Morbidity and Mortality Weekly Report. While it is possible that older people have more opportunities to be infected than younger people, like to live in a nursing home, which is considered unlikely, because young adults face many other people in the workplace and schools.

In contrast, the number of cases is higher among older Americans strongly suggest underlying biological vulnerability true, perhaps exacerbated by pre-existing disease earlier, according to data from China , sharply increased the risk of both infection and serious illness.

That may explain why even though older Americans represent 31% of the cases, they accounted for 45% of hospitalizations, 53% of ICU admissions, and 80% of the deaths, the CDC reported.

In contrast, no ICU admissions or deaths were reported among people younger than 20.

That, too, fits the data of the country- other countries. In, for example, which has the initial surge of cases, the mortality rate in Covid 19 patients aged 80 and over was 10.4%, compared with 5.35% at 70-somethings, 1.51% in patients 60-69, 0, 37% in 50 -somethings. the lower levels seen in younger people, fell to zero in those 29 and younger.

In an alarming development, however, scientists in China are now reporting that the new coronavirus does not spare the very young. In the first retrospective study Covid-19 among children in countries where the pandemic began, they counted 2,143 cases in children. Of them, those in the journal Pediatrics, more than 90% were mild or moderate, confirming previous observations that children are at lower risk of severe disease. (That may be because the molecules that allow the virus to enter human cells seem less developed in children.)

But 6% of cases of severe child and even critical, compared with 19% of adult cases. And in the findings described, almost 11% of Covid-19 cases in infants severe or critical, although no baby died. An important caveat, however, is that most of what doctors believed Covid-19 may have other respiratory diseases, including respiratory syncytial virus, which is known to cause severe disease in children.

Analysis CDC calculates US cases from February 12 to March 16; 4226 reported to the CDC. Starting on March 14, however, the number increased to 500 or more per day, and many cases have not been calculated or even identified because of the scarcity of test coronavirus. A by researchers at the University of Notre Dame estimates that, at the time President of the Trump last week, there were probably about 22 876 US cases, the actual number is almost certainly between 7451 and 53 044.

The CDC does not have complete data (such as the use of ICU) for all cases are calculated, and therefore provide a range of estimates.

More than raw numbers, percent of total cases provide a sense of risk for different age groups. For example, only 1.6% to 2.5% of the 123 infected people 19 and under were treated in hospital; do not require intensive care and none have died.

A roundup of stories on this day STAT.

However, from 144 cases in people 85 and older, 31% to 71% were hospitalized and 6.3% for the 29% required intensive care. The mortality rate in the age group is 10% to 27%.

In contrast, among those 20-44, 14% to 21% of the 705 cases were hospitalized and 2% to 4% to the ICU; 0.1% to 0.2% died.

The price for middle-aged people fall between the extremes, while 29% to 44% of patients 65-74 whohospitalized and 8% to 19% required intensive care; 2.7% to 4.9% in this age group died.

About 49 million people in the US who are 65 or older.

Experts emphasize that the population age structure of a country has great implications for how it should focus on containment and mitigation measures.

“age structure, along with early detection and treatment, is also likely to explain the lower number of deaths in South Korea and Singapore compared to Italy,” said demographer Jennifer. Dowd of the University of Oxford, who analyzed how the age structure of a country can use to guide its response Covid-19

in South Korea, the outbreak is concentrated in the younger church members; less than 4% of cases there have been in people over 80. Singapore has had only one death was reported, he pointed out, probably because it has only 10 cases in people over 70 and one on a person over 80.

“it has become clearer that the deaths and critical cases are highly concentrated in old age,” said Dowd, the infection tends equally common in young people but often produces mild symptoms or none. Although some models have projected the health care system disorders and millions of deaths in the United States alone, he said, “we thought that combining the age structure is important for predicting the threshold at which the capacity of health services especially overwhelmed.”

it means that the national population that skews older, such as Italy, the efforts to not “change the spread,” said Dowd. But they changed the threshold for when the demand in hospitals and ICU exceed their capacity. Social distancing measures, including orders to shelter in place, therefore it needs to be more aggressive or less depending on the age structure of the population.

In Italy, 22% of the population is 65 or older, compared to 17% in the US, raising hopes for a less catastrophic health care details.

Guys, there are a lot of false news around the internet about the various medications for coronavirus and fake notifications UNICEF. Read about them and share with your friends so as to prevent unnecessary panic and the spread of misinformation:

This seems fine with Brad if “only” 10-27% of those over 80 die when infected. So the “rational” people should go about their business as usual and potentially infect the population at the expense of the most vulnerable? I think he thought irrationally and that they are following the guidelines of information (Ierational) people who gave us guidelines for handling this virus is rational people

David, I think this issue he is selfish penis ,

Regarding infants with severe disease, Stanford just published some data coinfection online today shows the level of co-infection are higher than previously published, raising the possibility that it was not good COVID -19 OR RSV, but perhaps both. small sample. Still interesting.

Thanks for updating the world with information in the case of pandemic covid 19.

Are there people in the community Biomed develops anti-coronavirus based enzyme limit? It will at least stop the spread of the virus in the body. In bacterial cells, restriction enzymes cleave foreign DNA, thereby eliminating the infecting organism.

from 20 to 30 years of age do not understand the severity covid19 and some believe that they can not get sick, such as 21 years of my step daughter believes, they should provide a curfew in all cities in America and published excerpts for the -people who ignore the law

No one cares what your children think

you read the statistics? I assure you that the problem is paranoia and people who think our police force will lead to nothing but more panic and unrest! 0% probability of death in people under 20 and only 10 to 27% in people over 80 so far in those countries. Not your problem, please just hide in and become paranoid and stop spreading your illness who are rational people who are worried about the sickness! FEAR!

I hear stepchildren can not get a virus because it is specifically a stepchild enzyme

does not seem responsible to mention that 1/5 of 20-44 years of age with COVID-19 treated in hospital without also mentioning that the population aged 20-44 years in question is limited only to those who go to the hospital looking foring testing and have symptoms severe enough to actually administered tests.

Hospital near I still tested almost nothing because they have very few tests, and one even ran out today. Statistics about the “young adults” are virtually meaningless given this broader context.

Agree Leigh. I am in a populated area of ​​Southern California and had an email from my health network that they would examine the patient by referral only and you have to have symptoms. They will not test without symptoms, so if you are exposed to a positive case but do not have symptoms they will not test because they do not have enough kit. I am sure we will see a huge uptick in cases of confirmed if they are properly tested.
