It’s cooled down again! At this time, there will be many babies with colds, coughs and fever in the circle of friends. ……

However, we must remind you that you should never take a cold lightly because it is a common disease in autumn and winter.

Because in this period, there is also a popular virus that pediatric hospitals attach great importance to, which is respiratory syncytial virus!

How terrible is syncytial virus? It is the first consistent pathogen of severe pneumonia in children!

Moreover, it is very similar to a cold in the early stage. Delayed treatment may cause many diseases, such as bronchitis and pneumonia, which may all be related to him!

So, what are the characteristics of respiratory syncytial virus? How should parents find out in time? How to prevent it?

Today, Keda University (ID: kexueyuer 2012) will talk with you!

Heavy can be fatal! You must know five characteristics of this virus.

Respiratory syncytial virus is one of the common respiratory pathogens in children.

Because it is related to respiratory infection and can fuse infected cells, it is called respiratory syncytial virus.

TA has the following characteristics:

(1) strong lethality, heavy can be fatal.

Respiratory syncytial virus is the main cause of pneumonia, bronchiolitis and even death in children under 5 years old.

In developing countries, more than 300 million children under the age of 2 are infected with respiratory syncytial virus and suffer from respiratory diseases every year, of which 2.5 million die.

26 groups of people are the most vulnerable to recruitment.

Respiratory syncytial virus (RSV) is a "good hand" who bullies and fears hard. It targets people with weak constitution, and the department has greatly helped you to take stock:

③ Highly contagious.

Respiratory syncytial virus can be said to be the "indestructible body" in the virus world, and it can survive for several hours on the surfaces of objects and unwashed hands!

It "likes" crowded places, and its main transmission routes are droplets and close contact.

It can be said that sneezing can be contagious.

④ It will be reinfected.

Children’s defense is weak, and the immune protection time of antibodies produced after treatment is short, so they may be repeatedly infected.

⑤ No vaccine.

There are two subtypes of virus, A and B, and each subtype is divided into different virus strains according to genotype, and the dominant virus strains keep rotating every year.

Therefore, no vaccine has been developed so far.

Then if the baby is infected with this virus, how should parents judge for the first time? Ke will teach you a few tricks.

Cold or syncytial virus infection? 3 strokes to judge

Mild respiratory syncytial virus infection and its early symptoms are similar to those of the common cold, so it is easy to delay treatment and cause a series of complications.

The ICU of a hospital in Guangzhou received six children within a week, and several of them were put on ventilators because of respiratory failure!

The culprit is respiratory syncytial virus.

How can parents tell whether it is a cold or a virus infection?

Keda teaches you three simple and easy-to-use methods here, remember to watch+forward!

① Look at the cycle.

The course of respiratory syncytial virus is longer than that of cold infection, and the treatment period is generally 10~14 days, and the treatment period of cold is generally 5~7 days.

② Look at the symptoms.

The main symptoms of a cold are fever, dry cough without phlegm and sore throat. Although the symptoms of respiratory syncytial virus infection are similar to those of a cold, they are much more serious than a cold.

Keda has prepared a "invasion road map" of syncytial virus here. Parents can judge according to the symptoms of the baby through this road map:

Summary: If the child has a cold for 3 to 5 days, the cough is getting worse, which affects eating and even wheezing, it is necessary to consider that the baby is targeted by respiratory syncytial virus.

③ Do virus nucleic acid detection.

When parents are not sure whether their children are infected with respiratory syncytial virus, they can do a respiratory syncytial virus nucleic acid test, and the test objects are mostly nasal secretions, and the results will be obtained in 15-30 minutes.

What should I do after I decide to be recruited?

Let ke teach you how to deal with the situation!

Don’t underestimate! There were four symptoms, and they were rushed to the hospital.

In fact, this virus is a bit "watching the baby eat" and has certain self-limitation. Generally, it will begin to recover in about 7-12 days.

As long as the child’s immune function development is relatively normal, and the respiratory symptoms are not serious, which does not affect eating, you can do mild care for the baby:

But when you meet these four situations, it is another matter. You must send them to the doctor as soon as possible!

① Difficulty in breathing, with the nostrils open and breathing hard, and the muscles below the ribs or thorax are depressed inward, and the breathing frequency is greater than 60 beats/min.

(2) fever > 38.5℃, and there will be repeated fever.

3 The child’s mental state is poor, such as irritability and refusal to milk; Or the desire to eat milk is acceptable, but due to frequent choking and spitting, the feeding amount has dropped by more than half.

④ Dehydration, dry mouth without tears when crying, no urine or oliguria in diapers for 6 hours, and dry skin.

Finally, having said so much, prevention is always the first. Please check this prevention guide quickly!

That’s all for today!

In a blink of an eye, the winter is coming, and my parents have followed Keke through another round of spring, summer, autumn and winter.

Please see the parents at the end of the article, moving their hands and watching.

Tell keda that you will still be here next spring!
