How Much Damage Does Acute Influenza Cause?
Influenza is highly contagious, and the Centers for Disease Control estimates that the virus that has been ravaging the U.S. this flu season has affected every state in the U.S. with flu epidemics and deaths this year, and that the flu has also occurred in many parts of Europe and Asia. The disease has also been reported in many parts of Europe and Asia. Due to the rapid onset of the disease, the influenza filtration viruses, which include A, B, and Fukien viruses, and staphylococcal and streptococcal infections that invade the respiratory tract and the mucous membranes of the nose, spread throughout the respiratory, gastrointestinal, cardiorespiratory, pulmonary, and urinary tracts, and even lead to systemic toxic symptoms. The disease is most common in winter and spring and at the change of seasons, in people with weak constitution or chronic diseases, especially in nursing homes. The peak season is from the end of October to the end of February. There are also times when it rains after a Santa Ana wind, when it is cold and when the temperature drops drastically; these are the times when the flu strikes. A small number of people are susceptible to the flu when exposed to dust, fumes, or toxic gases from factories, and some children who are physically weak, have glandular disorders, or young children with enlarged tonsils are susceptible.
Symptoms of influenza attack appear chills, high fever, headache, sore throat, body aches and pains, tiredness and weakness, sleep and appetite disorders, etc.; severe acute inflammation of the nasal mucosa and immediately spread throughout the nasal cavity, the patient feels that the entire nasal cavity dry, tearing, sneezing, and then outflow of a large amount of nasal mucus followed by coughing, nasal congestion, and then nasal mucus becomes viscous and finally turned into a pus-like, and blocking the nostrils, so that the nearby mucous membrane epidermis erosion, due to the congestion and swelling of the nasal mucosa. The congestion and swelling of the mucous membrane of the nose causes severe nasal congestion, inability to breathe through the nose, dull sense of smell, or hoarse voice, and no taste in food.
In some cases, the infection recurs a few days after recovery, and the symptoms worsen. In severe cases, the nasal cavity is affected by the Eustachian tube to the middle ear canal, resulting in otitis media or paranasal sinusitis. It also spreads to the pharynx, causing pharyngitis, tracheitis, bronchitis, costochondritis, pneumonia and other complications. Usually, if you are in good health, it will gradually return to normal in 7-10 days. For those with poor health, 80% to 90% of rhinitis cases become chronic rhinitis (chronic simple rhinitis, chronic hypertrophic rhinitis, atrophic rhinitis), or even chronic paranasal rhinitis. It even turns into chronic paranasal sinusitis.
