Unlikely...: Though one may contract a virus by touching a contaminated surface and then touching the eyes, nose or mouth, the timing of your niece's illness makes it unlikely. Croup is usually caused by a virus infection, most often a parainfluenza virus. After the third day of symptoms, a patient will begin to clinically improve.The cough may in itself represent a post-viral cough that may persist for weeks. ...Read more

Shedding for awhile: Viral shedding, or period of contagiousness, for these types of viruses can last weeks, and are shed through the upper respiratory structures. However, since most of the shedding occurs during the time that the person is feeling very sick and febrile, let your son's behavior and overall appearance be your guide. Most daycares and schools require a 24 hour fever free period (without medications). ...Read more

Classic croup is: caused by a virus,which causes swelling in the upper airways.There is no vaccine or way to become immune to the virus.Generally, children "outgrow" croup as their airways become larger.Or...perhaps this isn't croup, but is a form of asthma,which could be triggered by an allergen,virus,or cold weather.If he has not had an allergy workup,it may be time.Then there may be meds to take to prevent it. ...Read more

Yes and no: Croup is triggered by several common respiratory viruses that can infect anyone at any age that is not immune.However, the response of each patient is different.Croup is a pattern that involves the rubbery and small airways of kids & primarily emerges in those 6m to 6yr. Older kids and adults tend to have a cold/cough or laryngitis with the same germ.If you had that strain as a kid you are immune ...Read more

Pneumonia?: I would bring your child into the doctor's office tomorrow. These findings could be due to a mild case of pneumonia.

Abx needed? 3 1/2 year old with 3 day fever spiking to 104 at nighttime s/p croup and subsequent otitis media. When to start abx?

When warrented: Fever by itself is not an indication for abx. Persistence of fever is an indication for a review of the history, thorough exam & testing if indicated. When evaluation finds a treatable condition, abx can be selected based on the agents suited for that finding and started immediately. ...Read more

Beginning stages of the croup. Some stridor and seal barking cough only when crying/coughing. Raspy. No fever. What can I do? 14m baby.

Symptomatic measures: Croup is a viral infection of the upper airway. Antibiotics will not help. Often humidified air--running the shower--or cold air will help. A lot of fluids also. If the stridor is severe or worrisome evaluation by the pediatrician is indicated. Sometimes one dose of a steroid is given to reduce the inflammation/swelling of the airway. Keeping the baby calm until this runs its course will also help ...Read more

Son has a barking cough. This would be 4th time with croup. Should I contact pediatrician again if there's no fever and isn't turning blue?

Mgt: His acute illness is most likely due to a viral infection. Humidified air with cool mist can help. Keep him well hydrated and please monitor his temperature. If he experiences any drooling or difficulty breathing a visit to the ED is indicated. Since it is recurrent, other considerations include a narrowing of the airway, which can be evaluated further. Has he had a Chest X Ray? ...Read more

My son had croup 2 days ago. My daughter today has a high fever, no coughing, but she vomitted once. Could it be the same virus or is it totally different. Will I have both a gastro and parainfluenza going through our home?

My son had croup 2 days ago. My daughter today has a high fever, no coughing, but she vomitted once. Could it be the same virus or is it totally different. Will I have both a gastro and parainfluenza going through our home?

Likely same virus: Most probably it is the same virus infection in both the children.

My 4y/o was diagnosed w/ croup,fever, cold. Blood work came back wbc of 3.1. Doctor said everything else was normal and due to infection? Concerns?

This can happen: While it's very common to see a high white blood cell count during an infection, it's also possible especially in children for it to be low. This is part of the body's immune response, and if all else is normal, then there is no particular concern or need for further testing. ...Read more
