The flu occurs every year, and it seems to be particularly fierce every year. Have you heard of these rumors:
”If you don’t drink water for 10 minutes and your throat is dry, the virus will invade your body and you will get the flu!”
”Drink more isatis root and antiviral granules to prevent and treat the flu!”
”This year’s flu So fierce, it is said that the influenza virus has mutated and upgraded!”
”I have had the flu this year, so I won’t get it again.”
Which one is true? Which is false? Let’s take a look at the “old bottom” of the flu together.
Why is the flu worse than the cold
Influenza has a rapid onset and the symptoms are heavier than normal colds. Although most people stay up for a few days and prescribe the right medicine or even not treat themselves, it is fine to have some complications, such as pneumonia, that can develop into severe influenza. A small number of severe cases progressed rapidly, and even died due to acute respiratory distress syndrome (ARDS) and/or multiple organ failure.
How does the flu spread
Influenza is mainly spread through droplets such as sneezing and coughing, and it can also be spread through direct or indirect contact with mucous membranes such as the mouth, nose, and eyes. In addition, contact with items contaminated by the virus can also cause infection.
Why flu is high in winter and spring
1. In winter, the weather is cold, and the indoor air is not circulated, which can easily lead to the spread of the virus. Especially when the air conditioner is turned on, the heating is turned on, and the ventilation is low, if one person has the flu, the others will be easily infected!
2. The cold weather makes people easy to catch cold, and the body’s resistance is weakened, and the virus will take advantage of the deficiency!
3. Low humidity, insufficient secretion of respiratory mucosa, especially nasal mucosa, dry and cracked surface, increasing the risk of infection.
How to tell if it is flu or cold
Let me give you a simple way to distinguish: For adults, if there is a fever as soon as the disease occurs, it is mostly flu; if it is just a runny nose, cough, and no fever, it is basically a common cold. This identification technique is only suitable for adults!
Is there any way for parents to identify children? Have! It is mainly judged by the child’s symptoms.
1. Influenza often causes sudden fever, and it is easy to burn very high at once, generally greater than (or equal to) 39°C. There are manifestations of chills when fever occurs, such as trembling all over, poor mental state, facial flushing, conjunctival hyperemia, muscle soreness, sore throat, etc. may occur. In addition, some babies will also have vomiting, abdominal pain, and diarrhea as the main manifestations.
2. There were no common cold symptoms such as cough and clear nose in the first two days of onset.
3. Especially in the season of flu epidemic, if the family has or has been exposed to people with flu-like symptoms, parents should be highly vigilant, your baby is likely to have flu.
Also need to be careful not to miss the bird flu. If you have a recent history of poultry contact, such as picking eggs in a chicken coop or duck nest at a farmhouse, or encountering on-site killing of chickens at a market, you should consider the possibility of avian flu.
In short, the common cold is the most common acute respiratory infection, while the flu is not. It is a systemic disease.
What to do if you suspect flu
Go to the hospital quickly!
Long-winded, when a child has symptoms that are suspected of flu, before the doctor diagnoses the flu, parents must not be smart, and give the child two anti-inflammatory drugs or antibiotics for peace of mind. No use at all!
How does a doctor determine that a patient is flu
The doctor will make a comprehensive diagnosis based on the patient’s epidemiological history, clinical manifestations and pathogenic examinations. Since the diagnosis of influenza generally takes 6 to 12 hours, sometimes doctors will judge whether antiviral treatment is needed based on the situation.
1. Clinical case: After
confirming that the patient has flu symptoms or a history of exposure to flu people, take the nasal mucus or throat secretion for rapid antigen detection of influenza virus. If it is positive, it is most likely to be flu.
At the same time, exclude other diseases that cause flu-like symptoms, such as acute pharyngitis, tonsillitis, rhinitis, and sinusitis.
2. Confirmed cases:
At present, for influenza, a drug recognized and recommended internationally is oseltamivir. It prevents the virus from entering the cell by sticking the influenza virus to the cell surface, thereby reducing the number of viruses in the body.
① Take nasal mucus or throat secretions for influenza virus nucleic acid test. This is currently the best specific and sensitive test, and it can distinguish virus types and subtypes, but it takes a long time and takes 6 to 8 hours to get results.
②Take respiratory secretions for influenza virus isolation and culture. If it is positive, it is diagnosed as influenza.
③Take blood to see the influenza virus-specific IgG antibody levels in the acute and convalescent sera. If the level of influenza virus-specific IgG antibody rises by 4 times or more, it is diagnosed as influenza.
It’s not that you need to complete the above three tests to be diagnosed. If you have flu symptoms, you can choose one of the three methods above to be diagnosed.
In addition, routine blood monitoring during fever is also very important. Although blood routine is of little significance for diagnosing influenza, it is still necessary to rule out bacterial infections. In case of flu and bacterial infection, antibiotics should be taken at this time.
The most effective way to prevent influenza
Ten thousand times again, influenza vaccination is the most effective way to prevent influenza.
Some people may ask, I heard that this year’s flu vaccine is a study of last year’s virus, can it deal with the latest flu virus?
Influenza viruses include influenza A (HIN1, H3N2) and influenza B (type BV and BY). If one year, according to the results of the study, the vaccine used contains three influenza epidemic strains, it can resist most of the influenza viruses. The possibility of infection with BY type is very small.
In short, it is better to fight than not, because there is still spring flu.
Other effective preventive measures are the same as the prevention of the new crown virus, such as avoiding crowded and poorly ventilated places during the flu season; wearing masks; washing hands frequently; maintaining indoor ventilation and regular disinfection.
Finally, announce the correct answer to the various rumors at the beginning of this article:
”If you don’t drink water for 10 minutes, the throat will be dry, the virus will invade the body, and you will get the flu!”
Correct answer: Drinking more water is indeed a good habit, but even if you take the whole There is no way to prevent the flu after the Pacific has drunk it.
”Drink more Banlangen and antiviral granules can prevent and treat influenza!”
Correct answer: These things have no effect on the treatment and prevention of influenza. At present, for influenza, a drug recognized and recommended internationally is oseltamivir. It prevents the virus from entering the cell by sticking the influenza virus to the cell surface, thereby reducing the number of viruses in the body. Less virus will shorten the course of the disease and reduce complications.
”This year the flu is so fierce, it is said that the flu virus has mutated and escalated!”
Correct answer: No! As a matter of fact, influenza is prevalent every year, and there has been a pandemic every few decades in history. It is not that this year is particularly fierce.
”I have had the flu this year, so I won’t have it again.”
Correct answer: flu is different from measles, and you won’t be immune after getting it once. If you are not careful, you may get it again.
