流感与H1N1
流感是流感的简称。流感病毒引起流感。流感病毒主要有三种类型：流感病毒A（可感染人和鸟类）、流感病毒B（只感染人）和流感病毒C（可感染人、狗和猪）。这些病毒被称为RNA病毒，这意味着它们在RNA中含有遗传物质。每种病毒都有亚型。它们被称为血清型。然而，由于甲型流感病毒的亚群造成更危险的感染和死亡，甲型流感病毒开始流行。猪流感是2009年广泛传播的流感之一。那是大流行**冒。
Usually flu is a seasonal infection. During winter it spreads. This can spread from the patient to another normal individual by droplets. When a person cough or sneeze this virus will be released in the air and inhaled by the other people and infect them. So using mask and using handkerchief while sneezing will reduce the infection from one to another.
Flu is a self limiting infection. The viral infection will settle spontaneously with out any treatment. The infected person may develop common cold, fever, cough, body ache, headache and sore throat. In serious illness they may develop pneumonia (Lung infection).
H1N1 is a serotype of the influenza virus which got the popularity last year. However H1N1 stain(sub group) is rarely caused death compared with H5N1 (another serotype of Influenza A).
H1N1 influenza share all the characteristics of the flu, but unlike other flu, its spread all over the world causing pandemic infection. The list below will show the pandemics of influenza virus that occurred early.
- 1918年导致西班牙流感的H1N1和2009年的猪流感
- 1957年导致亚洲流感的H2N2
- 1968年导致香港流感的H3N2
- 2004年导致禽流感的H5N1病毒
- H7N7，具有非同寻常的人畜共患病潜能[20]
- H1N2，人、猪和鸟类特有
- 氢9N2
- 氢7N2
- H7N3型
- H10N7型
Infection control:
Simple measures can reduce the infection rate; good ventilation, sunlight and washing hands regularly have proofed to reduce the infection spreading from one to another. During pandemics the mask was used.
Treatment for flu is mainly supportive. Vaccine is available for flu. But the duration of this immune protection is for short period (1 or 2 years) because the virus changes time to time.
