Get red eye disease should pay attention, may be infected with H7N9 bird flu
According to a report released by the World Health Organization in November 2016, there are currently three types of influenza viruses known: A, B, and C. Influenza A virus infects humans and many different animals. Influenza B viruses spread only from person to person and cause a seasonal epidemic. Influenza C virus can infect both humans and pigs, but the disease is usually mild and rarely reported. Humans can be infected with bird flu and other human flu co-infected influenza viruses, such as subtypes of bird flu viruses such as alpha-H5N1, alpha-H7N9, and alpha-H9N2, as well as subtypes of influenza viruses such as alpha-H1N1 and H3N2. The current outbreak of bird flu in China is the zoonotic flu virus type A H7N9. Why named after H7N9? According to the combination of different types of viral surface proteins, hemagglutinin (H) and neuraminidase (N), influenza A viruses are classified as subtypes. There are 18 different hemagglutinin subtypes and 11 different neuraminidase subtypes. According to the host source, influenza A virus can be classified as bird flu, swine flu or other animal influenza viruses. Examples include alpha H5N1 and alpha H9N2 avian influenza virus subtypes and alpha HlNl and H3N2 swine influenza virus subtypes. All of these Avian influenza viruses are different from human influenza viruses and are not easily transmitted from person to person. Infection of H7N9 Avian Flu Symptoms Human infection with bird flu and other human co-infected flu can cause disease ranging from mild conjunctivitis to severe pneumonia and even death. Disease characteristics, such as latency, severity of symptoms, and clinical outcomes, depend on the virus subtype that causes the infection. With regard to human infection with the H7N9 virus, current data indicate that the incubation period ranges from 1 to 10 days, with an average of 5 days. The average latency of both viruses is longer than the incubation period of the seasonal influenza virus (2 days). Many patients infected with the H7N9 Avian Influenza virus developed abnormally rapidly. The common initial symptoms are high fever (body temperature 38 degrees or more) and cough. It has been reported that there have been symptoms and signs involving the lower respiratory tract, including dyspnea or shortness of breath. Upper respiratory symptoms such as sore throat or rhinitis are less common. Diarrhea, vomiting, abdominal pain, nosebleed or bleeding gums, and chest pain have also been reported in the clinical course of some patients. Complications of infection include hypoxemia, multiple organ dysfunction, and secondary bacterial and fungal infections. The mortality rate of human infection with the H7N9 subtype virus is much higher than that of seasonal influenza. H7N9 bird flu infection route H7N9 bird flu infections include: close contact with infected birds (live birds or dead birds); close contact with infected poultry secretions, excreta; direct contact with bird flu virus; also through the conjunctiva and damaged skin can cause infection . Can H7N9 bird flu infect the eye? H7N9 bird flu can cause infections through the conjunctiva. What is the conjunctiva? The conjunctiva is a transparent film covering the inner surface of the eyelid and the white surface of the eye. The conjunctiva helps prevent damage to the eyeball caused by foreign bodies and infection. The conjunctiva itself can also be irritated by chemicals or allergies, or it can be infected by viruses or bacteria. It can cause eye pain, itchy eyes and congestion (ie, we often say red eye disease). How to prevent H7N9 bird flu? The public should avoid contact with live animals in their daily lives, not to mention sick and dead poultry, especially in areas where winter and spring seasons and epidemics occur. If contact is required, wash hands as soon as possible; in addition, efforts should be made to change the habits of purchasing and consuming live poultry, and to purchase chilled fresh poultry, chilled birds and their products with quarantine certificates. Raw poultry meat and eggs must be fully cooked and thoroughly cooked. After processing raw poultry meat and eggs, thoroughly wash hands; food processing should be done separately; if there are fever and respiratory symptoms, wear masks as soon as possible. Visit.
