With regard to swine flu overwhelming influx of news, especially yesterday, WHO will be their warning level raised to 5 to see pictures of wearing big masks seems reminiscent of that year's SARS, their hearts do not panic Introduction and Yu.

Why do people become infected with swine flu?
Pigs are the virus crossed the species of the "springboard"

The swine flu epidemic caused by human is due to a variety of animal influenza swine influenza in a special status in the decision. Has been shown that pigs are a variety of animal and human influenza viruses "intermediate hosts" is a leap of other species of animal influenza viruses infect humans "springboard." Scientists have for the first time in 1918 influenza pandemic in the world the reasons why a detailed investigation and found that avian influenza virus first infected pigs in 1910, and gradually evolved into the swine influenza virus, and then spread the virus from pigs to humans.

Swine influenza virus mutations lead to human transmission

Scientists in the past of human infection with swine influenza report contains an analysis of 50 cases infected with swine flu cases are distributed, and 61% have a history of contact with sick pigs, from person to person transmission is rare. More recently, Mexico and other countries of human infection with swine influenza virus in patients, the vast majority did not come into contact with pigs, has been identified as among humans, indicating that swine influenza virus could mutate into a human influenza viruses.

This virus is a mixture of
World Health Organization announces that: The virus is a hybrid, which concentrated swine influenza virus, human influenza viruses and avian influenza virus characteristics. Although the swine influenza virus in which to play a certain role, but the current flu appeared briefly named as swine flu is not accurate.

At present people are infected with swine flu outbreak has the following characteristics:

First, the outbreak of swine influenza virus by a new variant strain caused widespread susceptible populations has given rise to transnational and transcontinental transmission.

Second, the emergence of cases of human transmission.

3 is currently in Mexico there are more cases of severe and death.

Fourth, the day before the onset of influenza patients already detoxification, some people are not infected with the disease, but still infectious, a high rate of latent infection and therefore can not rule out the possibility of the epidemic spreading to China.

Because of these characteristics above, it has brought the difficulty of prevention, it is recommended to note these points from the following:
1, to avoid contact with flu-like symptoms (fever, cough, runny nose, etc.) or pneumonia and other respiratory patients;
2, pay attention to personal hygiene, wash hands frequently with soap and water, especially after coughing or sneezing;
3, to avoid contact with pigs or pig went to a place;
4, to avoid visiting crowded places;
5, with tissue paper when coughing or sneezing, cover mouth and nose.

The year in Guangzhou SARS prevention and control team leader Professor Zhong Jiaxi traditional Chinese medicine is given aPrescriptionSo that we can prevent swine influenza:

North, 10 grams almonds, mulberry leaf, chrysanthemum, loquat leaf, Platycodon grandiflorum, Forsythia, Yin-hua of 12 grams, puerarin, raw Adlay, reed rhizome, Daqingye of 15 grams. Wash the herbs, water-impregnated Emulsion, raging fire to boil for 15 minutes can be taken. Prevention of herbal tea to drink twice a day, continuous drinking for three days, after which you can pause, if the swine flu epidemic continues to expand worldwide, you can drink herbal tea and then a timely manner to prevent
