Vietnam: A/H1N1 flu outbreak: People ignore dangerous source

 I have to post this excerpt from the CDC on where the A/H1N1 came from.  Hopefully Vietnam will understand more.

Where did the 2009 H1N1 flu virus come from?

The 2009 H1N1 influenza virus (referred to as “swine flu” early on) was first detected in people in the United States in April 2009. This virus was originally referred to as “swine flu” because laboratory testing showed that its gene segments were similar to influenza viruses that were most recently identified in and known to circulate among pigs. CDC believes that this virus resulted from reassortment, a process through which two or more influenza viruses can swap genetic information by infecting a single human or animal host. When reassortment does occur, the virus that emerges will have some gene segments from each of the infecting parent viruses and may have different characteristics than either of the parental viruses, just as children may exhibit unique characteristics that are like both of their parents. In this case, the reassortment appears most likely to have occurred between influenza viruses circulating in North American pig herds and among Eurasian pig herds.  Reassortment of influenza viruses can result in abrupt, major changes in influenza viruses, also known as “antigenic shift.” When shift happens, most people have little or no protection against the new influenza virus that results. For more information, see “How the Flu Virus can Shift: Drift for Shift.”

Spray chemicals for prevention of influenza A/H1N1.
Influenza A/H1N1 still shows the complicated movements appear as consecutive deaths this flu. The functional departments in the Mekong Delta are implementing drastic measures to stop while people are pretty vague about this flu.
Also in Vinh Long After appearing deaths due to H1N1 influenza, the Health Department has purchased 500 tablets of Tamiflu for special treatment and prevention, Dr. Nguyen Thanh - Hospital Director of Vinh Long - said Hospital has established Steering Committee and the prevention of influenza A, with nearly 20 doctors and nurses, nursing, science Lay in bed for 20 - Infection with the service received, the cases or suspected influenza A . If an outbreak, the hospital will spend the whole of science Bed Spread 40 - Infection serve the epidemic. Dr. Thinh Nguyen Kim - Deputy Director of the Health Center in Tam Nong (Dong Thap) - said that the Prevention of influenza by households is limited, few people seek medical facility flu vaccine shots (one dose of influenza vaccine formulations from 2012 to 2013, including three strains: A/H3N2, A/H1N1 and influenza B strains ). Currently, the center is only 230 doses of flu vaccine shots for people. Every 3-5 days only to district health centers vaccine shots.
