Group B Streptococcal Infection Scarlet Fever
Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more
What is the connection between urine infection in my 4 year old daughter that is just recovering from scarlet fever?
None: Scarlet fever does not lead to urinary tract infection. One of the complications of a strep infection is, however, something called poststreptococcal glomerulonephritis. This refers to inflamation (not infection) of the kidneys after a strep infection, usually beginning 8-14 days later. It usually resolves after a few weeks, but there can be complications, so you should see your pediatrician. ...Read more
Strep: Scarlet fever is a rash produced by a toxin secreted by group a strep usually when they are causing strep throat. The rash is red, feels like sandpaper, may predominate in creases in the skin, there is sparing around the outside of the mouth (circumoral pallor), and it blanches with pressure. ...Read moreSee 1 more doctor answer
Group A strep: Scarlet fever is caused by infection with group a streptococci, the same bacteria that causes "strep throat". In scarlet fever, the strep bacteria releases a toxin that gives you the generalized sandpaper- like rash. Most patients will also have a sore throat, fever, and enlarged cervical lymph nodes. The treatment for scarlet fever is the same as strep throat-antibiotics such as penicillin. ...Read more
Maybe: If you really caught it from that cousin & not at random, the strain you have would be one that produces the red rash. Treatment started before the rash appears may stop it. Scarlet fever is really an archaic term left over from the pre-antibiotic era, when many fevered off & on for days with it.A common name applied to the rash now is scarlatina. ...Read moreSee 1 more doctor answer
I had scarlet fever as a child. I'm now 46 and all rapid strep tests result in faint positive-culture comes back neg. Is the SF somehow to blame?
No: The rapid test samples mucous/germs in your throat. It has no way of being influenced by your past medical history.Your throat mucous can never yield that data. The "faint" false positive has been proven negative enough times that it suggests a degree of unreliability for the test used, or how it is being done. ...Read moreSee 1 more doctor answer
A week ago Friday my 8 month old daughter was diag with strep and put on amox. for 10 days...7 days and 13 doses later I saw the rash. Took her back in and Dr. said was prob strep rash (which I learned was scarlet fever tho she never used that term.). Bab
The germ: Some group A strep germs carry an extra piece of genetic code that triggers a toxin that can cause the rash. If someone has a strep infection in their throat it usually shows up within 12 hrs of the first fever. If the infection is treated very early, it may not show up at all. A strep germ without the extra gene will not trigger the rash. Scarlet fever is an old term used back before penicillin. ...Read moreSee 2 more doctor answers
Possibly: Some strains of strep a strains carry an extra gene plasmid that controls the production of a chemical that enters the blood & causes the generalized red rash of scarlet fever. Not all strep a strains do, but if you did catch strep from someone with the rash it would likely produce the same rash in you within 24hrs of the first fever. Early rx prior to firm establishment of the germ might stop it. ...Read moreSee 1 more doctor answer
Yes and no: The strep rash is what used to be the most prominent feature of scarlet fever. But the term is more of a historical one. There was a time (lest we forget) that we did not have antibiotics. Scarlet fever described a systemic strep illness that could last more than a week with high sustained fevers over 103 and the rash.Most would recover but some developed rheumatic fever afterward. ...Read moreSee 1 more doctor answer
If a child has strep & gets scarlet fever, will the rash show up immediately when the symptoms start or can it take a few days for the rash to start?
Usually soon: The rash producing chemical that is generated by the strep is created after the start of the infection when it has reproduced in enough numbers to make the rash toxin.Studies suggest it will be evident by 12 hours after the appearance of fever in the illness.Not all strep will produce the rash, only those with the extra dna to make the extra toxin. ...Read moreSee 1 more doctor answer
Definition is strep: The term "scarlet fever " applies to strains of strep a that have the additional dna to make a red rash. The infection may be in the throat, or other site (skin, anus) and still produce the rash and fever. Strep throat includes strains of strep a that may or may not produce a rash.Their location in the throat is rather specific. ...Read moreSee 1 more doctor answer
Doesn't matter: Scarlet fever is just an archaic name for strep associated with a red rash that often led to intractable high fever (weeks)in the era before penicillin. Today it has no significance other than being a strain marker.About 15-20% of strep strains have an extra gene that codes for a chemical that gives the rash.If you got your strep from bro, you would likely get a rash, but doesn't really matter. ...Read moreSee 1 more doctor answer
Part of Strep: Scarlet fever is produced by the breakdown if you will of the strep bacteria. Not everyone who has "strep" develops the rash. The scarlet fever rash is more common in children. If you suspect you have a strep infection, seek treatment asap in order to avoid complications. ...Read moreSee 1 more doctor answer
