RS virus hos barn och bebis – symptom och smitta

RS virus hos bebis som får inhalation

Fakta och råd om RS-virus hos bebisar. Direkt av barnläkare. Varje vinter kommer RS viruset tillbaka och föräldrar till nyfödda undrar hur man ska tänka. Vilka symptom har RS? Behöver man söka sjukvård med en snuvig nyfödd om det är RS? Kan syskon gå på dagis och kan en förkyld mamma smitta?

RS virus hos bebisar

RS, eller RSV, är ett förkylningsvirus som ger ovanligt tjockt slem. Alla barn får RS innan de är tre år gamla. Efter en RS-infektion har man en viss immunitet, alltså skydd, mot ny infektion. Hos ungefär ett av hundra barn, särskilt spädbarn, kommer det tjocka slemmet att ge så mycket andningsbesvär att de behöver vård på sjuhus. De flesta bebisar klarar alltså av sin RS-virusinfektion själva, fler ju större de blir. Sjukdomen blir värre och värre i fem dagar och därefter långsamt bättre.

Svårt att andas eller svårt att äta vid RS-virus

De två symptom som gör att bebisar behöver sjukhusvård vid RS är att de har svårt att äta eller svårt att andas. Båda symptomen beror på att slemmet försvårar andningen i bebisarnas små luftvägar. Hemma kan du hjälpa bebisen med det genom att spola näsan med koksalt. Du kan läsa om hur du gör i inlägget om förkylda bebisar. Om bebisen sedan kan äta och andas utan alltför stor ansträngning kan du fortsätta vara hemma och hjälpa bebisen att rengöra näsan.

Sjukhusvård vid svår RS virus hos bebisar

På sjukhus eller i hemsjukvård hjälper man bebisen med maten genom att sätta en tunn silikonslang, en sond, genom näsan ned till magen och ger mat i den. Andningen hjälper man genom inhalationer. Man kan också hjälpa bebisen att få upp slem genom att hålla bebisen i famnen och studsa upp och ned på en stor pilatesboll.

Hos ett fåtal barn räcker inte sondmatning, inhalationer och andningsgymnastik. De kan behöva behandling med syrgas i högflödesgrimma eller CPAP. Enstaka barn behöver också respiratorbehandling under några dagar för RS. Av de barnen har många någon riskfaktor för svår sjukdom, som för tidig födsel, hjärtfel eller lungsjukdom.

Inhalation with saline can help a baby with RS virus

Riskbarn för svår RS

RS virus hos barn som har ännu mindre marginaler och kroppsliga resurser än friska nyfödda, som mycket för tidigt födda barn (före vecka 26 och som är under 6 månader), eller barn med svåra hjärtsjukdomar, svåra lungsjukdomar eller sjukdomar i hjärnan som gör att de inte kan hosta ordentligt och har nedsatt andningsfunktion redan från början, kan bli livshotande.  Detsamma gäller RS hos bebisar med svåra, ovanliga immunbristsjukdomar.

Baby in respirator after heart surgery, then RS can be really dangerous.

Om ditt barn tillhör någon av de här grupperna kan det vara aktuellt att ge en förebyggande medicin (Synagis) mot svår RS-infektion. Barnet får medicinen som en spruta en gång per månad under RS-säsongen. Medicinen är dyr (4000 kronor/månad under RS-säsongen) och bara barn som tillhör en riskgrupp får medicinen. Kontakta ditt barns läkare om du undrar om det här är aktuellt. Synagis minskar risken för sjukhusvård för RS med ungefär 50% hos de barn som får den.

RS virus smitta

RS-virus finns i mängder i saliv och snor. Det smittar det genom direktkontakt, att man får snor/saliv med virus på handen och tar på sin bebis som suger på handen och genom  hosta och nysningar. Vid hosta och nysningar kommer det ut miljontals mikroskopiska salivdroppar som alla innehåller RS-virus och alla kan smitta inom 1-2 meter från den som nyser.

Contagious older siblings often infect babies with RS virus

Att skydda bebis från RS-virus

Det viktiga är alltså att bebisen inte har direktkontakt med en förkyld person. Det går ju bra med vuxna, men med förkylda storasyskon är det svårt. Man får göra så gott man kan. Här är några bra grundregler.

1. Låt inte förkylda människor ta i bebisen. Föräldrar undandagna. Inte för att de inte kan smitta bebisen, utan för att bebisen behöver sina föräldrar även om de är förkylda. Förkylda storasyskon ska inte röra sina bebissmåsyskon om det går.

2. Parents with a cold wash their hands before holding their baby.

3. Cold sufferers coughing and sneezing into their arms must do so at more than one metre distance (preferably more than that) from the baby.

Det florerar mycket råd kring att man ska undvika kollektivtrafik, undvika folksamlingar, caféer och allmänna platser. Bedöm själv om det finns stor risk för att någon hostar eller nyser inom en meter från barnet. I så fall tycker jag du ska överväga att välja annat transportmedel eller annan aktivitet. Men som sagt, RS flyger inte i luften om inte någon nyser eller hostar, så på en glesbefolkad buss eller vanligt café eller bibliotek är risken för smitta liten.

Should you keep older children at home from kindergarten to protect your baby from RS?

Of course, there is clearly less risk of the newborn being infected with RS virus or other cold viruses if the older sibling does not go to daycare. But getting a new sibling is often difficult enough for a two- or three-year-old, who may be at a difficult age. In addition, being excluded from friends at preschool is more than many siblings can handle.

Så länge du inte har en bebis som är särskilt infektionskänslig (extremt för tidigt född, icke-opererat svårt hjärtfel etc), så skulle jag rekommendera att låta storasyskonet gå på förskola. Förkylningar, och även RS hör livet till. Helhetssituationen i familjen är viktig. Om du å andra sidan trivs bättre med att ha båda barnen hemma – gör det.

Vilka bebisar ska skyddas mot RS virus?

Det kan vara klokt att försöka skydda bebisar bebisar under tre månader så noga du bara orkar. Alla barn som är för tidigt födda och krävt vård på neonatalavdelning till de är minst 6 månader. Barn med svåra hjärt- och lungsjukdomar eller immunbrister längre än så, men prata med deras läkare för individuella råd.

Who is protected against RS virus?

When a healthy child starts preschool after one year of age, the infections will start to come. Then the risk of serious RS infections requiring hospital care is also very low. When a younger sibling is 6 months old, I think that older siblings can take care of the baby after washing their hands, even when the older sibling has a cold.

On the website of the Public Health Authority, you can read weekly reports every year during the winter season for how much RS virus there is in the community.

  1. Hello,
    Vi har en 2,5årig dotter och en 4mån grabb.
    För en dryg vecka sedan skrevs vi ut från sjukhuset efter att grabben haft rs virus.
    Hur länge skall vi vänta med att låta dottern börja gå på förskolan igen? Löper han stor risk till att bli allvarligt sjuk igen om hon får gå på förskolan nu?

    1. Hey!
      Lillkillen har ju redan haft sitt rs-virus, så det kommer han inte att få igen om dottern börjar på förskolan. När han äter bra själv utan sond och inte behöver några inhalationer så är han ju i sitt “ursprungsskick” så att säga och jag skulle skickat storasyster till förskolan. Några barn som haft RS-virus får därefter förkylningsastma och blir extra sjuka även i andra förkylningar, den som kan ge bäst råd för er gosse är en läkare som träffar honom eller er BVC-sköterska.

  2. Hey! Have read your blog about the risk of infection and handling to avoid infecting babies. Meet my 9 year old grandchild about once a week. Now, during the winter I can feel tight in my nose, a little heavy in my forehead and can sneeze vigorously without coughing but not feeling directly ill. Absolutely do not want to infect the grandchild and I wonder how I, as an adult, know if I carry rs virus? Can I take a test at a health center? This hits me quite often and I would like to meet the grandchild without risk. Grandmother

    1. Hi Björg!
      It is probably not so informative to take a test at the health center, because I am pretty sure you can carry the virus without any risk of infection. And on the contrary, even if you take a test one day, you might get the virus the next day. I interpret your letter as not really feeling cold when these symptoms occur. I think you should meet the grandchild, except when you REALLY feel cold with proper cunning, maybe a little fever and sickness.
      All's Well!

  3. Hello,
    I have a 1.5 year old and a 4 month (premature birth would really be 2 months now)
    Both have become cold and it turned out to be probably the RS virus. it has now been borne out that the little one has a cold asthma.
    We are now in day 9 with rs virus and little ones are starting to get much better even though inhalation procedure is needed and he is still small in the food.
    What about walking and such? Do you dare take out little man on a walk in the carriage? Or can the cold ruin his recovery even more? Right now it is at home at -5 and I think that plus degrees maybe you dare bring the little one out? I find nowhere what they say about cold asthma and go out and forgot to ask the doctor.
    Grateful for help!
    Mvh Lisa

    1. Hey! So hard for you! When the lungs are recovering, sometimes chilly air can cause a little more coughing. So I would probably be a little careful until he does not need inhalations and eats well again before I set out on longer winter walks. Then of course it is not as cold air in an embedded carriage as it is in the air, so shorter cases I would think goes well. And then you see how the little one reacts.
      All luck!

  4. Hey!
    Our 4 month baby was cold the night of Christmas day and the following night after he went to sleep for the night he got a breathing break. Fortunately, the father lay in bed next to him and breathed life into the baby again as he did not resume breathing even though the father tried to stimulate breathing by patting his back. RS was later found in hospital. Question 1) Can RS cause apnea-like breathing stops where the baby just quietly stops breathing?

    In our history we have been in 2 times before for the corresponding respite, 1 which occurred 2 days after the 3 month combination vaccine, and a series of 3 respite breaks on the same evening 10 days later. In connection with this, Rhinovirus was found.

    All the world's blood tests and examinations have been done and have not shown anything abnormal, the only doctors tested is that the central nervous system is underdeveloped and that in case of viral infections can go like this, do you agree?

    The baby is full and otherwise normal in development.

    1. Hey!
      Yes, the RSV infection can cause respiratory arrest, usually the first few days of the infection. What a wonderful thing that your baby still did well! You seem to have received a thorough investigation of knowledgeable pediatricians.

  5. It is almost only talked about serious progress for smaller children. We have a kid of 1 year o 9 months who has been healthy and healthy from the beginning. Now he has spent 6 nights in the barbecue area with oxygen, adrenaline and drip. In total, he (and his 4-year-old sister with similar symptoms) has been home for three weeks so far and he is still really at risk. In addition, both have had eye inflammation and ear inflammation during the journey.
    Personally, I would like to say that the RS virus will affect more children over the years. At least that's our experience so far. Thanks for a great blog. Mvh Jonas

    1. It is most common with serious procedures for smaller children. Must have been tough for you with such a month ... Get the kids on!

  6. Hey!
    We have a son now before Christmas. Bf V 38. In the middle of the RS season. He has a big brother of 2 years who has been / is cold m cough most of the time he has been on parole (started there in early September). The best thing for the baby is not to let the big brother go to fsk, because there he brings with him new infection home. But it is a long time for May, when the RS season is over. Feels terrible to send big brother to fsk, but at the same time horrible that he must not be where he gets to spend time with other children ... unsustainable. Feels like it will be wrong no matter what you do 🙁 choose between which child should have a good time. Should one keep the big brother at home for a month and then hope for the best when the big brother is back on fsk? Certainly impossible to answer… I know 🙁

  7. Hello
    We will have children in early February. Thinking of keeping big brother home from preschool until baby is 2 months. What is it like to meet other healthy preschoolers? Would they be able to carry the RS virus and infect big brothers before they had any cold symptoms or is it only when it becomes noticeable that it is infected?

  8. Thank you for your posts about rs and how babies should and should not breathe! 🙂 It was they who made me suspect rs on our 8 day baby and also made me go another turn to the emergency when dry cough and raspiness turned into thick tough mucus and tongue. Now she is posted and under full control and feeling as okay as she can 🙂 Thanks for an informative and factual blog!

    1. Oh, thank you for such response! That is exactly what we hope for with the blog, that it will help babies and children feel as good or okay they can! With or without medical care.

  9. Hey! I am a very worried mom to my little guy who was born 3 months premature. He is now 7 months okorr and 4 months corrected. You write that all children who are under 6 months should be protected as much as you can. But then to the usual premature issue; is it corrected or uncorrected age you mean? One of our doctors says that our son now has an immune system like a 4-month. Our son does not get synagic since he was born v.26 + 6 but the same doctor says that if our son gets cold then it can go harder on his lungs because he has received respiratory treatment. Feels very uneasy and I long for May when hopefully the RS season is over. Now we live very isolated and do not meet so many because basically everyone is cold ..

    1. I would protect him as much as I ever endured this entire winter season. However, I would try to make friends. That said, someone has to cough or sneeze for the virus to spread in liquid droplets in the air, or it spreads through hands. So a normal well-behaved adult should not have to infect a baby. They only need to walk a few meters before sneezing or costing in the arm fold. And should not take the baby if they are clearly cold.

      Almost all small babies admitted to hospitals with RS infection are infected by pre-cold storasized shoes at the age of two who go to kindergarten.

  10. Hi, I have a little guy in almost 4 weeks. He is now in the second week with a cold. He is slimy in the airways and spurs some in between. His eyes are also somewhat fluid. He is also ruthless (sounds like he is shaking himself often). I'm worried it might be RS. We are in contact with bvc, meet once a week and they know about his cold, but as long as he eats, kisses and poops and of course does not have a fever they do not seem to worry. In the meantime it has seemed to be on the road to improvement but now I feel that the mucus and snoring have gotten worse again. He breathes heavily sometimes. Could it be RS? Can I stay calm as long as he eats?

    1. BVC is right. As long as he can eat, he can handle his cold. It may be RS or other cold virus. No matter what: he can eat, and as long as he doesn't have to fight physically with every breath, he can manage his infection himself.

  11. Hi.
    My little daughter is 10 months and now her little guy friend has found out today that he has rs. We were there and visited on Tuesday for a little while, but they did not have direct contact with each other. How long does it take before it breaks out? And my little girl had a difficult start from the beginning, her lungs were filled with meconium so she could not breathe on her own but had to lie in a respirator. But since then she still has a "problem" she is small in food, always has been. She weighs only 7 kg, so I am particularly worried that she will be affected by rs or stomach flu.

    1. RS does not infect the air, except in coughs and sneezes. Babies need direct contact with each other, or they are spread with hands that carry saliva or lice with viruses. So careful hand hygiene, avoid meeting chilled toddlers and allow chilled adults to cough or sneeze except squirt for the child. Understand that you are extra worried about your daughter's difficult start, but she is quite big now in the RS regard and as a doctor I am not so worried about 10 months with RS. Although they sometimes need to stay in for a few days for inhalations and probe feeding. And I understand that if you want to avoid when it's such a struggle with the food and you have memories of a difficult start in hospital. It takes 3-5 days from infection until the disease breaks out.

  12. Hey!

    My 4 month old daughter has just had a bunch of really hard rs with pneumonia and atelectasis which gave a really tough course. And I've been thinking and thinking if I should have protected her more. My answer, despite the misery, is no.

    Not that it wasn't bad. However, because the protection comes with a price. A common advice, from many pediatricians, is to leave babies outside in the carriage when picking up and leaving store siblings at preschool. Had I done that, Selma would probably have survived this week, which has been horrible but will not give but in the long run.

    On the other hand, she had to lie in the wagon outdoors. Often she had woken up, cried and noticed that I was not there. I can't imagine it's good for the connection. It wouldn't have been good for my stress level either.

    I really wish sometimes doctors could think a step further. What is the greatest risk for long-term impact? A rs infection or that the child may be left alone and crying? And what do you do to the mother who is told that she should have acted differently when her child is seriously ill? Now I just happen to be tough enough to think that the doctor is wrong and that I am right - attachment is obviously more important to me than rs protective for a four month and I am not going to take on the blame. But that self-assurance has no other.

    A long reflection on a post that doesn't really say anything about my way of thinking.

    Greetings,
    Johanna

  13. I have a question for you, hope it's okay.
    Our son, who is almost 3 years old today, got rsvirus, then he was almost 10 months old ..
    He got really REALLY BAD. After 5 days at home and countless conversations until 1177 he got big problems with breathing, plus he was then pale .. he had only been completely still for several days .. just got a little scolding .. he was dehydrated too, although we tried to get him fluid compensation .. high fever .. well when we got to the nursery he had an oxygen allowance of 80% .. he was inhaled and they had thought we would be able to go home, but then the doctor changed then his oxygenation did not get better .. so we were hospitalized, he was given oxygen mask and inhaled 1gg / h .. they at first thought he had got pneumonia .. he was completely gone poor! well he needed cpap because he could not breathe properly .. he did not eat either so he was fed with gruel ... they were lunging him and luckily there was nothing!
    we had to go home after 5 days in the hospital… he had cpap 1½ days .. (think it was 2 nights in a row) ..
    Last fall we discovered that he has a cold asthma, the doctors hear nothing when they listen to him, but he can not lie down at all and sleep when he coughs CONSTANT .. and then we tried to give his big brother's windpipe dilation (we had tried then cough medicines like lephetone, ventoline, mollipect) airomir that worked! we had to give 3 tight doses and voila! we all got to sleep!

    but my thought is, can asthma have existed BEFORE the virus attacked? and that is why he got so crazy bad ?? Or could the rs virus have caused his cold asthma he has now?
    (yes we had to go in during the first colds after rsv inf to inhale him but then came the summer and then he had only cough but nothing that was heard directly on the lungs according to the doctors then)… ..

    well now this became so long .. would really appreciate an answer! 🙂
    had so good! very interesting blog you have! :)

    1. Hey!
      It is quite common for babies who have severe RS infection to get cold asthma then, BUT no one knows what is the chicken or the egg. Is it that babies with “sensitive lungs” get both severe infection of RS and cold asthma, or is it that severe RS damages the lungs and then it becomes cold asthma?

      What may be good to know is that in most children, cold asthma grows away as they grow older. But some have asthma, of course.

      Greetings
      Cecilia

    2. Thank you very much for your reply! Yes just .. hard to know. We both parents have asthma .. so I think he had the "sensitivity" even before .... (I also have very severe allergies so ..)
      One more question - an allergy test was done on our minimum (which was also such a sickness in rsvirus that I wrote about above), when he showed signs of allergy last year at the pollen bloom in May and June, he then got aeurius (spelling?) Floating shape, which helped well, but sometimes he also needed eye drops. But iaf, now there was a new form of allergy test where they stabbed him in the finger, And the result showed no allergies at all, is this common among toddlers ??
      He turns 3 in the middle of April, the test was done at the end of January ..
      (Maybe it's like his infectious asthma, it's not visible / audible, but the trouble is there anyway .. I think ??)

      hard to find information on this….
      Mvh Malin

  14. Oh, had totally missed this question! But better late reply than nothing at all. A working RS vaccine for pigtails would probably quickly enter the vaccination programs if there were, but there is none. There are antibodies that prevent serious illness, but they must be given once a month and are extremely expensive, therefore they are only given to children who are at really high risk of very severe RS disease.

    What a tough first time with the baby! Nice that the baby is doing well now! It is known that children who need hospital care for RS are more at risk of cold asthma than children who did not need it, however, they do not usually get severe RS infections that require respiratory care or CPAP care again.

  15. What about vaccine against rs? Has it ever come to talk in health care to vaccinate little babies against rs if the virus can be so bad for them?
    I have a son who was born 3 weeks premature, he had immature lungs and also got an infection so we were in the neonatal for 12 days. His condition was critical for 2 days, he had c-pap and has been on a respirator because he couldn't breathe enough. He was declared healthy after 12 days, now he is 6 months and is healthy and healthy, is growing well, has not been sick yet. Because of his difficult start in life, do you think he would be considered a "risk-child" if he got the rs virus now or in the near future?
