Treatment regimen, new A/H7N9 flu issue, the patient should be taken specimens, confirmed by tests, genetic analysis to determine definitely the flu. Need to distinguish influenza caused by the H7N9 flu, such as influenza A/H5N1, H1N1, pneumonia caused by viruses.

The Ministry of Health recommends the suspect needs to be examined at the hospital, isolated and specific diagnostic tests.Patients should be used antiviral drugs oseltamivir or zanamivir as soon as possible. Patients can be severe: respiratory failure, multiple organ failure. Was discharged after only 3-5 days of good health.
"After discharge the patient should continue to monitor body temperature for 12 hours / times. If the temperature is over 38 degrees C in two consecutive measurements or other unusual signs wants to see now, "said Dr. Nguyen Van Kinh, Director of the Tropical Disease Hospital Surgeons (Hanoi) note.

According to Phan Trong Lan, Deputy Director, Department of Preventive Medicine, the A/H7N9 flu virus is a new strain of influenza virus gene derived from poultry and some birds, capable of causing human infection leads to inflammation severe pneumonia and rapid progression and high mortality.
Ministry of Health recommends measures to prevent A/H7N9 influenza infection include increased communication, transportation trade, slaughter poultry not use quarantine regulations; cover your mouth and nose when coughing, sneezing, blowing your nose with a tissue or clean hands; protective use, wash hands with soap when exposed poultry; avoid close contact with people with respiratory disease.

Beware of breeding birds
Professor Trinh Quan Huan, a senior Health Ministry's note, in Vietnam have not recorded any case of influenza A/H7N9 infection. However, with the arrival back of the A/H5N1 flu virus in humans (the most recent cases of child 4 years of age), the existence of influenza A/H1N1, increase the risk of recombinant influenza virus outbreak spread to humans.
Origin influenza virus from poultry have high adaptability, are constantly changing their genetic makeup to avoid resistance of the body.
"The return of the A/H5N1 flu, the existence of the pandemic influenza A/H1N1 and A/H7N9 influenza risk invade our country is really worrying for the transformation of the virus is difficult to anticipate. It is especially dangerous because humans do not have antibodies against the new virus ", Prof. Huan note.
According to Professor Trinh Quan Huan, ominous birds carrying the virus status without signs of the disease, similar to pathogenic avian waterfowl without manifest disease remains a source of infection for humans. 
According to his Magisterium, the H7N9 flu virus, the H5N1 virus is known to exist in wild birds. The migration can spread germs make people concerned about the outbreak of a flu pandemic. They may also exist in breeding birds: pigeons, birds.
To limit dangerous viral strains from birds, the family birds for breeding birds in cages and in separate areas.http://www.thanhnien.com.vn/pages/20130410/vi-rut-cum-gia-cam-de-bien-doi-thanh-chung-nguy-hiem.aspx
