WHO experts for the first time found that severely ill patients with influenza A H1N1 influenza majority of obese people.

According to Singapore’s “Lianhe Zaobao,” reported that the hospital around the world, influenza data, body mass index of more than 40 morbid obese, there is often difficult to treat and even fatal respiratory complications. Take the case of Manitoba, Canada is in the ICU in the patients, five of them, three are obese; fat ratio was the highest in Europe, Scotland, the first two deaths occurred in Europe and the European one-fifth of the proportion of 1 death ratio; Peru, the first two deaths were 38-year-old woman and 4-year-old girl, both obesity.

In the fat proportion of the population accounted for only 1.6% of Japan 2146 the proportion of confirmed influenza among those who did not seriously ill or dead.

So far, the WHO has not yet sorted out the global data. Bethesda in the United States National Institute of Allergy and Epidemiology Director Fauci said: “You do not have to go to Scotland, or Japan can also be discerned.”

He said, according to statistics, obesity is clearly the factors that lead to exacerbations.

Fauci said that if look back at the past, the proportion of seasonal influenza, I believe that will find that obesity is an unfavorable factor.

Since April, the Mexico and the United States since the detection of cases, there were already 429 people were killed, among which 75% have asthma, diabetes and other chronic diseases, including pregnant women.

Scientists have not yet clear whether obesity because they originally had the problem of heart disease and diabetes, so that they suffered or were they too much fat is causing trouble.

Armstrong World Health Organization, chronic group of doctors that the chemical composition of fat cell secretion may cause chronic, mild inflammation, slow down the body’s immune system reaction speed, and narrow the respiratory tract. In addition, the excess fat cells will increase the pressure to the chest, penetrating the chest of oil has weakened lung function and increased pulmonary blood flow. Obesity are often the activities of small, shallow breathing, therefore, once infected with influenza virus, breathing becomes difficult.
