Influenza
How is avian flu treated?
First, patients suspected or confirmed with avian influenza should be isolated and treated as early as possible. Second, antiviral medications such as oseltamivir and zanamivir should be taken within forty-eight hours of onset, the sooner the better. Third, physical cooling or antipyretic drugs should be administered during high fever, and medications like Compound Licorice Tablets and Ambroxol Hydrochloride can be used to relieve severe cough and phlegm. Oxygen therapy using nasal cannulas or masks may be administered depending on the degree of hypoxia. Fourth, strengthen supportive treatment, maintain internal environment stability, and prevent complications.
What are the symptoms of flu?
Influenza, commonly known as the flu, is an acute respiratory infectious disease caused by the influenza virus. What are the symptoms after contracting the flu? Typically, the onset of influenza is quite sudden, and symptoms such as chills, high fever, headache, dizziness, body aches, and fatigue can appear quickly. Generally, the symptoms in the nasopharyngeal area are relatively mild and prolonged, and may include sore throat, runny nose, tearing, coughing, etc. After contracting the flu, it is important to actively cooperate with medical treatment and also to ensure isolation to prevent infecting others.
Routes of influenza transmission
Influenza, also known as the flu, is a disease caused by infection of the upper respiratory tract with the influenza virus. It is characterized mainly by sore throat, cough, and fever, and some patients may also experience nausea, vomiting, and diarrhea. The primary mode of transmission of influenza is through droplets, which occur when an infected person sneezes or coughs, and their secretions, such as nasal discharge, are inhaled by others. Additionally, the virus can be transmitted through the digestive tract and mucous membranes of the skin. If a healthy person comes into contact with the secretions of an infected person, such as through skin contact or orally, they may also be infected. Therefore, it is crucial to isolate from those infected with the flu.
What is type B influenza?
Type B influenza is a type of epidemic influenza characterized by a rapid onset, feeling feverish and chilled. Body temperature usually rises quickly within hours, reaching 39 to 40 degrees Celsius, or even higher. It is accompanied by headache, general body aches, fatigue, and reduced appetite. Its respiratory symptoms are relatively mild, including dry throat, sore throat, dry cough, and possibly diarrhea. Type B influenza is difficult to distinguish from the common cold and typically requires laboratory identification for diagnosis.
How long does the flu vaccine last?
Compared to the common cold, influenza causes more severe symptoms and is more contagious. Antibiotics are ineffective against it, but influenza can be prevented, and vaccination is the most effective way. Currently, the immunity from the influenza vaccine generally lasts about one year. It starts to work about a month after injection, but after six months, the concentration of antibodies in the body gradually declines. Additionally, the virus mutates every year, so an annual vaccination is necessary to provide effective protection, reduce symptoms, and prevent influenza.
symptoms of influenza
The symptoms of influenza vary greatly from individual to individual. The typical presentation first follows the trend of influenza outbreaks. After coming into contact with an infected person or the influenza virus, symptoms such as fatigue, limb pain, nausea and vomiting may be experienced. Some may also have symptoms like runny nose, sneezing, sore and dry throat, and a sensation of a foreign body in the throat. Clinically, the main symptoms are limb pain and body fatigue, and some may also experience a rise in body temperature. It is advisable to drink more water, rest more, and measure body temperature. Choosing antipyretic analgesics can generally relieve symptoms, and antiviral medications can also be used as treatment directed toward the cause. (Medication should be used under the guidance of a doctor.)
What are the symptoms of pharyngitis and influenza?
Pharyngitis influenza mainly involves inflammation of the mucosa or submucosal tissues of the pharynx, generally affecting the lymphatic tissue of the throat, primarily caused by viral or bacterial infections. Clinically, symptoms include dryness and a burning sensation in the throat, a rough feeling, and during severe cases, swallowing pain that may even radiate to the ear. If accompanied by systemic symptoms, such as acute inflammation, the symptoms may vary depending on age, immunity, and the virulence of the virus or bacteria. These symptoms can include fever, headache, decreased appetite, and limb soreness, which are all characteristic of pharyngitis, and during an acute attack, resemble symptoms of influenza.
Is the flu easily contagious?
Influenza, also known as the flu, is an acute respiratory infectious disease caused by the influenza virus. Typically, it starts suddenly with symptoms such as high fever, headache, fatigue, conjunctivitis, and widespread muscle pain. Respiratory symptoms like sneezing, nasal congestion, and runny nose are relatively mild in comparison. The flu is mainly transmitted through contact and airborne droplets, and it is highly contagious among the general population. It also has a high incidence rate and can lead to outbreaks; if not properly controlled, it can pose a severe threat to human life.
Influenza vaccination time
Influenza vaccines are primarily used to prevent epidemic influenza. Currently, there are three types of influenza vaccines in our country: Type A, Type B, and Type C. The best time to vaccinate for influenza is in September and October, because epidemic influenza often outbreaks in winter and spring. Therefore, getting vaccinated during these months can greatly prevent the transmission of epidemic influenza. The main groups recommended for influenza vaccination include preschool children and the elderly or frail, such as those with chronic diseases. Those with chronic conditions are at high risk of exacerbating their diseases after contracting epidemic influenza. These groups are particularly suitable for influenza vaccination. During the influenza vaccination period and before getting vaccinated, it is important to ensure that one is not having a cold, including symptoms like fever, to proceed with the vaccination.
How many days does it take to recover from the flu?
Influenza is primarily a disease caused by an infection of the upper respiratory tract with the influenza virus. It is a contagious disease that can spread among people, leading to an outbreak. Although influenza is a frightening illness, it is a viral infection characterized by being self-limiting, meaning that whether or not medication is used, the patient's condition can improve on its own. Typically, the course of influenza can improve on its own within about 7 to 10 days. At this time, it is sufficient to use medications that reduce fever, relieve pain, or treat nasal congestion and coughing, since patients generally recover on their own after about 7 days, and medication is only needed to alleviate symptoms. (Please use medication under the guidance of a doctor.)
