Respiratory syncytial virus

Published on

Respiratory syncytial virus (RSV) causes
mild, cold-like symptoms in adults and older children. However, it can cause
serious problems in young babies, including pneumonia and severe breathing
problems. In rare cases it can lead to death. Premature babies and those with
other health problems have the highest risk. A child with RSV may have a fever,
stuffy nose, cough and trouble breathing. Tests can tell if your child has the
virus.

RSV easily spreads from person to person.
You can get it from direct contact with someone who has it or it by touching
infected objects such as toys or surfaces such as countertops. Washing your
hands often and not sharing eating and drinking utensils are simple ways to
help prevent the spread of RSV infection. There is currently no vaccine for
RSV.

  12. 12. CausesRSV is very contagious. It is transmittedthrough direct contact with nasal droplets from aperson who is infected.RSV also can stay on environmentalsurfaces, such as doorknobs, toys, 11

  14. 14. Causeshave symptoms is about 4 to 6 days.BecauseRSV does not give protectionfrom future infections, people can getRSV many times—even during asingle season. The first infection is usually the mostsevere. After that, 13
  15. 15. Causesany infections generally have mildersymptoms. 14
  16. 16. SymptomsMost children have had RSV by the time theyare 2 years old, but many parents might not evenrealize it. That’s because RSVsymptoms are very much like the symptoms of amild-to-severe cold: runny nose, 15
  17. 17. Symptomscough, mild fever, and sore throat. Infants with RSValso might have lessappetite than usual and be tired or fussy.Sometimes, because congestion isheavy, infants can’t feed very well, and they maybecome dehydrated (have a 16
  18. 18. Symptomslower than normal amount of fluids in the body).Most people will have symptomsabout 4 to 6 days after being exposed to the virus.However, RSV can be particularly dangerous 17

  20. 20. SymptomsMost people with RSV’s cold-like symptomsdo not necessarily need to visit a healthcareprovider. But if you or yourchild have any of the following symptoms, youshould call your healthcareprovider immediately: 19
  21. 21. Symptoms-- Trouble breathing-- Rapid breathing-- Episodes of sleep apnea (when breathingstops for a short time)-- Wheezing that can be heard 20
  22. 22. Symptoms-- High fever-- Cough with green or yellow mucus 21
  23. 23. DiagnosisMost people with RSV will simply have arunny nose and a cough and dont need to visit ahealthcare provider. The virusgenerally runs its course with the help of hometreatments. In fact, 22
  24. 24. Diagnosisin healthy children, it’s often not necessaryto find out whetherthey have RSV or the common cold because thetreatment is the same. 23
  25. 25. Diagnosischildren with heart and lung problems, the elderly,and people with weakenedimmune systems—to treat RSV properly,a healthcare provider mayneed to diagnose the illness. Generally, ahealthcare provider can use a 24
  26. 26. Diagnosisnasal swab or nasal wash to diagnose RSV.Sometimes, they use a chest X-ray oroxygen saturation test to check for lungcongestion. 25
  27. 27. TreatmentTo treat RSV is to treat its symptoms.Drinking electrolyte-replacing fluids—not sugarysodas or sportsdrinks—regularly will prevent dehydration(abnormal loss of body fluids). 26
  28. 28. TreatmentAcetaminophen (Tylenol, for example) will help toreduce fever and relieve headache.Note that children with viral illnesses such as RSVshould never take aspirin.In these cases, aspirin can lead to the potentiallyfatal Reye’s syndrome. 27
  29. 29. TreatmentYou should encourage children in your careto blow their noses, and you can use a bulb syringein infants to suction nasalpassages clear of mucus. Plenty of rest will helpkeep children comfortableuntil they get better. Good hand washing canprevent spread the virus. 28
  30. 30. TreatmentIn more severe cases, people with RSV mightneed treatment to help them breathe.Some healthcare providers mayprescribe a medicine called a bronchodilator tohelp open airways (tubes that 29

  32. 32. PreventionResearchers have been working towardan RSV vaccine since the 1950s, but novaccine is yet licensed for use.The best way to prevent RSV is good hygiene andinfection-control practices, 31
  33. 33. Preventionsuch as washing your hands frequently with soapand water and avoiding sharingfood, cups, or utensils with infected people. Usinghand disinfectants will alsokill the virus. 32
  34. 34. PreventionHealthcare providers may give infants athigh risk for serious RSV infection or complicationsSynagis (palivizumab).Healthcare providers give such infants Synagis inmonthly injections during theentire RSV season, because each injection givesprotection for only 30 days. 33
