U.S. researchers have updated the previous influenza A H1N1 influenza virus in the population between the spread of some of the characterization that the influenza virus has the ability to attack people of all ages and in all age groups were all lethal lethal.
In addition, U.S. scientists believe that the influenza A H1N1 influenza previously only a “mild” flu is not an accurate description, because severe symptoms are hospitalized You Sancheng patients are subject to “intensive care.”
Attack all age groups
In 1088, and all deaths in patients diagnosed as research object, the U.S. researchers found that influenza A H1N1 influenza virus, as previously described, as is indeed more infections occur in young adults group, compared to the traditional seasonal influenza, Influenza A H1N1 influenza infection lower the average age group.
But the Influenza A H1N1 influenza in patients with severe symptoms once the cause of its relatively more deadly.
“Our study found that once you need hospital treatment, if you are elderly, a greater risk of death,” participate in this study, California public health officials said贾尼丝路易3.
Louis and its research partners will update the description of Influenza A H1N1 influenza published in the latest issue of “Journal of the American Medical Association,” on.
Elderly population is also dangerous to
U.S. Centers for Disease Control and Prevention Center, Thomas Frieden, director of the Louis team, the results of this study agree with the view that the transmission characteristics of influenza A H1N1 influenza update the description and the Center for Disease Control and Prevention consistent follow-up research.
Some epidemiologists previously pointed out that influenza A H1N1 influenza infection is not easy people over 65 years of age. However, Frieden said, based on a statistical analysis of patients with confirmed cases, influenza A H1N1 influenza can infect the same people over 65 years of age, and may easily lead to complications due to have a more serious consequences.
“From the data shows that, once the (people over 65 years of age) infected with it (H1N1 influenza), the severity of seasonal influenza, compared favorably,” Frieden said.
Frieden suggest that doctors should remind the elderly to increase awareness of influenza A H1N1 influenza alert.
However, Frieden pointed out that the Centers for Disease Control and Prevention, and will not be prompted to change this new influenza A H1N1 influenza vaccine inoculation object first. He said the first need for vaccination in the population remains young adults with asthma patients, obese patients and pregnant women.
Obesity plays a catalyst
Louis said that at this stage, medical personnel should “first of all to dispel the previous influenza is ‘mild flu’ error awareness.”
“Influenza can become very serious. In the report, we found that 30% of patients require intensive care,” she said.
Statistics also show that in all hospitalized patients diagnosed with influenza A H1N1 influenza, the mortality rate as high as 11%; over the age of 50 hospitalized patients, the mortality rate of over 18%.
In all deaths, the highest frequency of complications are viral pneumonia and acute respiratory distress syndrome. In addition, the incidence of obesity increases the risk of complications.
In the 268 cases of adults over the age of 20 critically ill patients, 58% of people are overweight, body mass index of more than 30,67% of the people were seriously overweight, body mass index of more than 40.
“It is clear that obesity increases the risk of playing a prominent role,” Louis said, “This is, for seasonal influenza are not available features.”
