Scarlet Fever Vs Fifth Disease
As a child I had a mild case of whooping cough despite being vaccinated, Scarlet fever, impetigo, fifths disease. I rarely get sick now and haven't been on antibiotics for years. Did I have an immune problem as a child? Or can this be normal?
A viral illness caused by parvovirus, also known as Erthema Infectiosum. It starts with a "slapped cheek" rash on cheeks and a flat red spotted rash, mostly on the arms and upper legs.

How would I know if I had rheumatic heart disease? Had scarlet fever that went untreated longer than it should have 22 years ago.
An exam could help:
Rheumatic heart disease is the result of a strep infection. Fortunately most don't go on to have heart involvement, particularly if the infection is treated.
If your heart valves were affected it would very likely be audible on physical exam. If your physician is suspicious, they may order an echocardiogram to confirm those suspicions. ...Read more
Anyone can get: Scarlet Fever, which is simply a strep infection with a rash. It is no more serious than a strep throat, and if diagnosed is easily treated with an antibiotic.

Think sunburn: The color is like a sunburn & the feel is like sandpaper. It tends to start first in the under pants area, armpits & folds of the arms with an interesting pale halo around the mouth.

No: Both are triggered by the same bacteria GABHS, but are different diseases. Rheumatic fever is caused by the overreaction of the own body's immune system, which may attack its own structures (like the heart and the joints). Scarlet fever occurs when that bacteria is infected with a virus that causes a toxin which makes the skin red and harsh but it may also cause rheumatic fever as a sequel. ...Read moreSee 1 more doctor answer
I see cases yearly: Scarlet fever in the days before antibiotics was a truly scary disease. Weeks of high temperature and pealing red skin rash were often followed by other complications. Today it is muted by treatment. The rash generally starts within 12hrs of a fever with any strain of strep that can make the erythrotoxin. Treatment kills enough strep to minimize the rash & shorten the illness. ...Read more

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
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
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
Contagious: The bacteria that causes scarlet fever can be spread through nasal or throat fluids by sneezing or coughing.

Washing hands is very important to minimize infectious spread. Public water sources should not be a source of infection. ...Read more
