11 has passed, and I use three words to describe my November: discounted cooling, life-seeking bills, and continuous syncytial virus infection.
The temperature dropped, and the minor problems of fever and cough were like a appointment. I came here together and couldn't help but refuse them.
Many parents don’t know: Behind these minor problems in babies, the culprit is [ respiratory syncytial virus ].
This inconspicuous virus can cause diseases such as bronchitis , pneumonia , etc. If you do not pay enough attention to the condition, the acute and aggravated condition may even endanger life!
What? You don’t even know it. Today, University of Science and Technology wants to make a good deal of it until you know it. Have you taken out all the small notebooks? Class starts!
Respiratory syncytial virus (RSV for short), is one of the viruses that can cause pneumonia and one of the most common respiratory pathogens in pediatrics.
Almost all children have experienced one or more infections before the age of 2 years old.
In order to give everyone a clearer understanding of respiratory syncytial virus, the University of Science and Technology has summarized several characteristics:
❐ The extremely lethal
Respiratory syncytial virus is the main cause of hospitalization and even death in children under 5 years old.
causes 34 million respiratory infections every year, and the death toll of children under under 35 is as high as .2 million.
And after natural infection with RSV, the antibody produced will have a short immune protection time and will be repeatedly infected.
❐ The contagiousness is super
Respiratory syncytial virus can be said to be one of the more tenacious existences in the virus world, and it can survive on the surface of objects everywhere and the unwashed hand surface for several hours!
It is often found in densely populated areas, and its main transmission routes are droplets and close contact.
It can be said that a sneeze can be contagious.
If you are directly exposed to objects contaminated by the virus or have close contact with the body, such as touching or kissing someone who has been infected with the virus, you will be infected.
❐ Specially to pick soft persimmons
Respiratory syncytial virus is a "good guy" who bullys the soft and fears the hard. When choosing an invasion object, people with [weak constitution] start to take action. The University of Science and Technology has taken a look for it for you:
➤ Premature babies and babies under 6 months
Among them, 2-6 months of age is the peak of the onset of bronchiolitis. Children within 6 weeks are at a higher risk of severe RSV infection.
And the probability of male baby infection is greater than that of female baby.
➤ Children with chronic lung disease, severe heart disease, immune dysfunction, cancer, and organ transplantation are also at a higher risk of illness.
❐ North-south difference of magic virus
✔ Northern Regional Epidemic Season: November - April of the following year, most of which are high in January and February.
✔ Southern Region: Popular throughout the year and mostly occur in summer.
Respiratory syncytial virus is self-limiting and will generally begin to recover from 7-12 days, but parents need to master basic condition judgment to avoid excessive anxiety.
❐ For mild symptoms, parents can deal with the symptoms of
respiratory syncytial virus infection and cold and its similarity, but it is a prelude to the onset of pneumonia and bronchitis.
Learn how to judge, remember one sentence: 1 looks at the cycle, 2 looks at the symptoms.
➤ Look cycle:
Respiratory syncytial virus has a longer course cycle than cold infection.
The treatment cycle of respiratory syncytial virus is generally [10~14] html for 6 days, and the treatment cycle of cold is generally [5~7] html for 6 days.
Respiratory syncytial virus has a 6-day incubation period of [2-8] html, and [4-6] html begins to show symptoms of infection such as cough and wheezing after 6 days.
➤ See the symptoms:
Cold is mainly caused by fever, dry cough, no sputum, and sore throat . Although the symptoms of respiratory syncytial virus infection are very similar to those of colds, is much more serious than colds:
✔ 1-2 days : Running nose, cough, and low fever (37.5℃-38℃) to moderate fever (38.7℃-39℃).
✔ 3-4 days : Paroxysmal cough, wheezing, and even difficulty breathing may occur.
✔ 5-6 days : Difficulty in breathing, wheezing further aggravates, reaching peak period, and cyanosis occurs in severe cases.
When the child has not recovered for a week and has gasped, he should consider that the baby is targeted by respiratory syncytial virus.
At this time, parents don’t need to panic, we can take care of them at home.
, check the nursing Tips ↓
➤ Use a nasal suction device and saline to clean up the sticky nose.
➤ Use an air humidifier to make your breathing smooth.
➤ Appropriately elevating the head position is conducive to the drainage of nasal secretions.
➤ Feed the child a small amount of water multiple times to ensure sufficient water intake.
In fact, this virus is a bit "just look at the baby". As long as the child's immune function develops normally and heals well at home, this virus can heal itself.
❐ Severe illness, hurry to the hospital
Although respiratory syncytial virus is self-limiting, severe illness may be fatal. Parents need to take their children to medical treatment in time if the following symptoms occur:
➤ Difficulty in breathing, open the nostrils and breathe hard, the muscles under the ribs or chest are sunken inward, and the breathing frequency is greater than 60 beats/minute.
➤ has a fever of >38.5℃, and there will be repeated fevers.
➤ Children have poor mental state, become irritable, and their feeding volume has dropped by more than half.
➤ has symptoms of dehydration, no tears when crying, no urine or oliguria in the diaper for 6 hours, and dry skin.
Parents cannot deal with the situations such as dyspnea and dehydration, and respiratory syncytial virus can cause pneumonia.
So when the above situation occurs, you must take the child to the hospital in time and let the doctor provide symptomatic treatment.
Regarding this virus that cannot be prevented without a vaccine, University of Science and Technology summarized a wave of issues that mothers are most concerned about:
Q1: Is the respiratory syncytial virus infection of a child with fever and cough? How will the doctor diagnose when he goes to the hospital?
A: is not necessarily true! influenza virus , adenovirus , rhinovirus , parainfluenza virus and some bacteria can cause these symptoms.
When parents are not sure whether their child is infected with respiratory syncytial virus, they can go to the hospital to ask a doctor for diagnosis.
The currently known respiratory syncytial virus detection is performed using respiratory syncytial virus nucleic acid detection kit . Most of the test substances are partial secretions of the nose, and the results are obtained in 15-30 minutes.
Q2: I heard that ribavirin can treat respiratory syncytial virus, but isn’t this medicine not for children?
A: Ribavirin has [selective inhibitory effect] on respiratory syncytial virus, , but the clinical effect is not certain.
Moreover, there is no atomizing dosage form for ribavirin in my country now. After judgment, experienced pediatricians will carefully choose to use atomizing inhaled hormones, bronchodilators and other treatments to make the child feel more comfortable.
After the symptoms improve, the corresponding symptomatic treatment will be performed.
Q3: Since There is no vaccine, how should parents prevent it?
A: All we need to do is to kill RSV in the cradle before preparing to invade. How to kill
? Come, look at the picture ↓:
000 yuan is sick, behave well at home (father) and mom, don’t go out to make a fuss to infect other children.
