H7N9 avian influenza and clinical characteristics
H7N9 is a subtype of the avian flu. All human influenza virus can cause avian influenza, but not all of the avian influenza virus can cause human influenza. The avian influenza virus, H5, H7, H9 can be transmitted to humans, which H5 highly pathogenic. The H7N9 subtype of avian influenza past is found not only in poultry between human infection.
Patients infected with the H7N9 strain of bird flu symptoms as acute onset, early in the course have high fever (38 ° C or more), cough and other respiratory tract infections and other symptoms, onset 5-7 days difficulty in breathing, severe pneumonia and progressive increase, some cases can quickly develop into acute respiratory distress syndrome, and death. Disease, not timely diagnosis and treatment, the prognosis is poor, with high mortality.
H7N9 avian influenza is not spread from person to person
After medical observation, there is no fever or respiratory symptoms, also found no epidemiological association between cases of close contacts with the H7N9 avian influenza. World Health Organization, pointed out that this is the first case of human infection with the H7N9 avian influenza virus, interpersonal transmission of the virus is not found. Highly sporadic disease is currently based, there is no evidence to support the cause of possible outbreaks.
However, we can not be taken lightly, the virus may with other influenza viruses through mutation restructuring is more suitable for reproduction in the human body, in ability to spread from person to person, so strict observation of the epidemic, scientific analysis of protection is very important.
Clinical diagnosis and diagnosis of patients should be treated in isolation; symptomatic treatment, oxygen, application of antipyretic drugs, cough expectorants; application of antiviral drugs for influenza antiviral treatment as soon as possible, the other type influenza antiviral treatment experience, the incidence of early use of the neuraminidase inhibitor class of antiviral drugs for influenza may be effective remains to be seen, but on the specific treatment of the H7N9 avian influenza virus infection studies.
