关于h7n9的英语演讲稿

H7N9 is a new flu virus,which was founded in Shanghai and An’hui province firstly.Up to now,there has been no vaccine to fight against the virus.By investigation,scientists have found that the gene of H7N9 influenza virus comes from the genetic recombination of Wild birds from Northeast Asia and chicken in Shanghai,Zhejiang and Jiangsu province.

H7N9,H stands for Hemagglutinin that can be divided into 15 Subtypes, N stands for Neuraminidase that consists of 9 Subtypes.Influenza viruses of all human beings can cause the poultry infected, but not all of the influenza virus of poultry can infect humans. In influenza viruses, H3, H5, H7, H9 can be transmitted to humans, H5 is highly pathogenic. H3 can infect dogs and humans.H7N9 previously only found in poultry and found no extraordinary infection. About the biological characteristics of the virus ,virulence and spread of power, there is no basis for analysis and judgment.

H7N9’s incubation period is generally less than 7

days. Patients generally present flu-like symptoms, such as fever, cough with little phlegm, and may be associated with headache, muscle aches, and general malaise. Patients with severe progression of the disease, manifested as severe pneumonia, the body temperature most of the last 39 or more, difficulty in breathing, and may be associated with hemoptysis; rapidly progressive acute respiratory distress syndrome, mediastinal emphysema, sepsis, shock, disturbance of consciousness and acute kidney injury.

The source of infection is not quite clear, but based on past experience and the epidemiological investigation, it suggests that the source of carrying the H7N9 virus may exist in poultry and poultry secretions or excretions.

For transmission.,it can spread through the respiratory tract, but also through close contact with infected birds secretions or excretions such as infection, direct exposure to the virus can also be infected. Now there is no interaction between the spread of conclusive evidence.

As for susceptible populations.,there is no definitive evidence to suggest that the susceptibility of human H7N9 . Existing confirmed cases are mainly adults.

The high-risk groups are the people who are mainly engaged in poultry production, sales, slaughter and processing industry, as well as 1 week before the onset of contact with birds.

Although it sounds very scary,but if we take good measures to protect ourselves,,it can be avoided.

Firstly,we should do more exercise and have enough sleep time to improve our immunity.

Secondly,we should try our best to avoid contacting with poultry.

Thirdly,when we eat eggs or chicken,please guarantee that they are cooked thoroughly.

Next,if we have a cold,we should go to see a doctor,because the symptom of H7N9 is the same as the unusual flu.

At last,please remember to open windows to allow fresh air in.

On the research,scientists find that garlic,aloes,mushroom,tomatoes and carrots can improve our immune against H7N9.

That’s all that I want to share with you. Thank you!

all patients had fevers and coughs in the early stages before developing pneumonia and breathing difficulties, china's health authorities said.

experts say genetic analysis shows the h7n9 virus can be treated with tamiflu, anantiviral drug that may slow the spread of influenza in the body.

wang xianjun, head of the shandong provincial center of disease control, said h7n9 is sensitive to neuraminidase-inhibiting medicine such as tamiflu, qilu evening news reported on wednesday.

there are no effective vaccines for h7n9 as yet, wang said, but using tamiflu may be effective in the early stages.
