Influenza B is influenza B, which is more common, is caused by influenza B virus, will be contagious, spread fast, and is more likely to cause outbreaks or small epidemics.
It is generally found in the elderly, children and other immunocompromised people, and is more common in winter and spring. Therefore, it is necessary to improve autoimmunity!
So, how to judge whether a child or adult has a common cold or a flu?
Influenza B has similar symptoms to colds, with fever, runny nose, sore throat, cough, etc.
Some patients with strong immunity can be cured without treatment, but some patients need to be treated with drugs, generally 1-2 weeks of treatment can be cured, if it is not good for a long time, there may be underlying diseases, to pay attention to.
Type B of influenza
Influenza B is divided into simple, gastrointestinal, pneumonia and poisoning. The different types of common symptoms are as follows:
Simple type: this type is more common, and the onset is generally more urgent. Patients may have high fever, headache, fatigue, loss of appetite and other manifestations, and a small number of patients may have cough, nasal congestion, dry sore throat, hoarseness and other symptoms. Body temperature generally reaches its highest value in 1 to 2 days, gradually decreases in 3 to 4 days, and gradually improves symptoms after defervescence.
Gastrointestinal type: less common, more common in children. The main manifestations are vomiting, abdominal pain, diarrhea, decreased appetite, etc.
Pneumonia type: relatively rare, mainly occurs in infants, the elderly, pregnant women and accompanied by certain cardiopulmonary diseases and immunocompromise, pneumonia type patients will have high fever does not go away, shortness of breath, due to the lack of oxygen in the body caused by the lips and limbs and fingertips appear purple, hemoptysis, extreme fatigue and other symptoms, and even respiratory failure, the highest case fatality rate, so it is necessary to pay great attention to it.
Toxic type: This type is rare and can show hyperthermia, convulsions and other manifestations of systemic toxemia, and in severe cases, shock or even death may occur.
What is the cause of B flow? How to prevent it?
Influenza B is mainly caused by the influenza B virus, which is often caused by the following two reasons:
Exposure to the source of infection: A patient can become infected when they come into contact with someone carrying influenza B virus.
Immunocompromised: Patients are more susceptible to viruses due to certain conditions such as cancer, bone marrow transplantation, pregnancy, etc., resulting in decreased immunity.
Influenza B viruses are mainly transmitted through droplets and contact, but are preventable.
First, during the epidemic period of influenza B, the room should be ventilated and disinfected regularly, and 84 disinfectant liquid or alcohol can be sprayed for disinfection.
Second, pay attention to personal hygiene and do a good job of personal protection. When coughing or sneezing, cover your mouth and nose with tissues, handkerchiefs, etc.; wash your hands frequently, try to avoid touching your eyes, nose, and mouth with your hands; eat a balanced diet, exercise in moderation, and rest enough.
Third, vaccination is currently the most effective preventive measure, and vaccinators can effectively reduce the probability of illness.
Finally, avoid close contact with people with flu-like symptoms and try to avoid going to crowded places during influenza epidemics. Confirmed patients need to be isolated at home, do not take the illness to work, go to class, and remember to wear a mask when going to the hospital. Patients suspected of having influenza B also need isolation and treatment.
How is B flow diagnosed and treated?
When patients have symptoms such as increased body temperature, headache, general aches, vomiting, diarrhea, etc. during the influenza outbreak, or symptoms such as prolonged high fever, shock, and breathing difficulties, they should seek medical attention immediately.
What tests do I need to do if I suspect influenza B?
When a patient is suspected of influenza B, routine blood tests, virus isolation, imaging tests, and viral nucleic acid tests can be done to help diagnose the diagnosis.
Some people will think that the test results are not influenza B, is not a waste of money? It's not that the doctor can treat it according to the results of the examination, so that the effect is fast and it can be more secure.
If you do not do the examination because you are afraid of wasting money, you will delay the condition, not only will you prolong the treatment time, but you will also spend more money, and the patient will be more miserable.
How is it treated after diagnosis of influenza B?
General treatment: during the illness, patients are mainly bed rest, drink more water, and if necessary, they can take oxygen or supplement fluids through intravenous fluids.
Symptomatic treatment: when the patient has symptoms such as fever, pain, and excessive sputum, the patient is given symptomatic treatment such as cooling, analgesia, and expectorant.
Antiviral therapy: within three days after infection, the use of drugs such as oseltamivir to inhibit the release of influenza B virus, reduce the spread of the virus, can speed up the recovery of the disease. However, it needs to be taken on the advice of a doctor and it is strictly forbidden to take it yourself.
Antimicrobial therapy: when the patient has a concurrent bacterial infection, a combination of antibacterial drugs can be used. Because of the different personal conditions, the medication is not the best and fastest, and it is necessary to use the drug according to the doctor's instructions.
After influenza B is cured, although a certain degree of immunity will be obtained, different types of influenza B viruses will still come to the door. If you want to fight the virus, you should pay attention to nutritional balance in life, choose a suitable exercise for yourself for a long time, and improve your own immunity.
