Early symptoms of avian influenza?

summary

The wide spread of avian influenza has increased the risk of human infection and brought great threat to human health. With the genetic variation of avian influenza virus, from H5N1 to h7n9, the number of human infected with avian influenza is also increasing, which increases the risk of avian influenza pandemic. It is necessary to understand the main clinical symptoms of avian influenza and correctly understand the disease. Early symptoms of avian influenza? Let's talk about it

Early symptoms of avian influenza?

Typical viral pneumonia, acute onset, early course of disease have high fever (above 38 ℃), cough and other respiratory tract infection symptoms. Dyspnea occurred 5-7 days after onset, severe pneumonia and progressive exacerbation, some cases can rapidly develop into acute respiratory distress syndrome and die.

Patients infected with h7n9 virus develop severe pneumonia with symptoms including fever, cough and dyspnea. However, the knowledge of all the symptoms that may occur after infection with influenza A (h7n9) virus is still limited. Whether the virus infection can cause mild cases or other clinical manifestations remains unclear. With the accumulation of more case information, the understanding of the disease will change.

Like H5N1, h7n9 can cause strong damage to cellular immunity. The prevention and control team of human infection with h7n9 avian influenza led by Li Lanjuan, academician of Chinese Academy of engineering, has previously found that compared with other avian influenza viruses, the average time of h7n9 virus from onset to acute respiratory distress syndrome is 7 days, and the average time from onset to death is 14 days, which is more dangerous. At present, the mortality rate of h7n9 avian influenza is close to 30%, and multiple organ failure has become a major cause of death.

matters needing attention

At present, although there is no evidence to confirm the existence of human to human transmission of h7n9 avian influenza, if a family member or friend is hospitalized with h7n9 avian influenza, it is better not to visit them, but to greet them by telephone. At the same time, we should pay attention to the prevention of cold, do not ignore the symptoms of cold, if found with fever or cough, sore throat symptoms must be timely medical treatment, so as not to miss the opportunity of treatment of avian influenza.
