|It is expected and seen as a norm in the early years.  
High levels of Metalloproteinase 9 and Tissue Inhibitor of Metalloproteinase 1 has been shown to disrupt the blood-brain barrier and thus, the cause of the febrille seizures observed in some infants infected with the virus <ref name="pmid25156011">{{cite journal| author=Kittaka S, Hasegawa S, Ito Y, Ohbuchi N, Suzuki E, Kawano S | display-authors=etal| title=Serum levels of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinases-1 in human herpesvirus-6-infected infants with or without febrile seizures. | journal=J Infect Chemother | year= 2014 | volume= 20 | issue= 11 | pages= 716-21 | pmid=25156011 | doi=10.1016/j.jiac.2014.07.017 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25156011  }} </ref>.  More severe disease pathology can be seen in the immunocompromised because it remains latent in the lymphocytes and monocytes after primary infection  <ref name="pmid19319952">{{cite journal| author=Bates M, Monze M, Bima H, Kapambwe M, Clark D, Kasolo FC | display-authors=etal| title=Predominant human herpesvirus 6 variant A infant infections in an HIV-1 endemic region of Sub-Saharan Africa. | journal=J Med Virol | year= 2009 | volume= 81 | issue= 5 | pages= 779-89 | pmid=19319952 | doi=10.1002/jmv.21455 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=19319952  }} </ref> <ref name="pmid11486597">{{cite journal| author=Yoshikawa T| title=Human herpesvirus 6 infection in transplantation. | journal=Nagoya J Med Sci | year= 2001 | volume= 64 | issue= 1-2 | pages= 11-8 | pmid=11486597 | doi= | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=11486597  }} </ref>. 
Requires a minimum age of 5 years, at least one event in a month, and a minimum period of 3 months.
==Causes==
 
Disease is caused by HHV-6 and less commonly by HHV-7 which are members of the Herpesviridae family <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume= | issue= | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>. HHV-6 has a linear, double-stranded DNA genome <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>. The HHV-6 has its primary variant, HHV-6A which is the associated with Roseola infantum while the other variant, HHV-6A has not been associated with any disease(s) <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>.
Persisting beyond the age of 5 years is termed pathological.  
==Epidemiology and Demographics==
 
Children are the most commonly infected. Newborns have passive antibodies to HHV-6 passed on to them from their mother which wanes by 4-6 months <ref name="pmid25462439">{{cite journal| author=Tesini BL, Epstein LG, Caserta MT| title=Clinical impact of primary infection with roseoloviruses. | journal=Curr Opin Virol | year= 2014 | volume= 9 | issue=  | pages= 91-6 | pmid=25462439 | doi=10.1016/j.coviro.2014.09.013 | pmc=4267952 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25462439  }} </ref>. By 12 months of age, incidence of the disease is about 40%, this increases to 77% by 24 months <ref name="pmid25462439">{{cite journal| author=Tesini BL, Epstein LG, Caserta MT| title=Clinical impact of primary infection with roseoloviruses. | journal=Curr Opin Virol | year= 2014 | volume= 9 | issue=  | pages= 91-6 | pmid=25462439 | doi=10.1016/j.coviro.2014.09.013 | pmc=4267952 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25462439  }} </ref>. Primary infection peaks between 9-21 months of age <ref name="pmid25462439">{{cite journal| author=Tesini BL, Epstein LG, Caserta MT| title=Clinical impact of primary infection with roseoloviruses. | journal=Curr Opin Virol | year= 2014 | volume= 9 | issue=  | pages= 91-6 | pmid=25462439 | doi=10.1016/j.coviro.2014.09.013 | pmc=4267952 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25462439  }} </ref>.
However, there are the 'late developers' who continue to experience physiologic urinary incontinence beyond the age of 5 years.
==Natural History, Complications and Prognosis==
 
Classical finding of Roseola infantum is very high fever which can be higher than 39°C <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>. This fever lasts for 3-5 days and can be accompanied by other symptoms like malaise, conjuctivitis, inflammed tympanum, anorexia, irritability, lymphadenopathy, cough, etc <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>. On sudden disappearance of the fever (3-5 days later), small, rose-pink, non-pruritic, blanching, maculopapular rashes appear first on the trunk and then spreads to the neck, face and extremities <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>. This usually lasts 1-2 days and ends the infection period <ref name="pmid28846307">{{cite journal| author=| title=StatPearls | journal= | year= 2020 | volume=  | issue=  | pages=  | pmid=28846307 | doi= | pmc= | url= }} </ref>.

Types of urinary incontinence Details
Physiological It is expected and seen as a norm in the early years.

Requires a minimum age of 5 years, at least one event in a month, and a minimum period of 3 months.

Persisting beyond the age of 5 years is termed pathological.

However, there are the 'late developers' who continue to experience physiologic urinary incontinence beyond the age of 5 years.

Clinical evaluation of these kids remains normal.

Pathological Organic: usually uncommon. In-depth investigations needed to be identified more so in cases that have not responded to conventional treatment
Functional or psychosomatic urinary incontinence: includes all forms of pathological urinary incontinence without anatomic or neurologic defects. Manifestations of which have been subdivided into:
Monosymtomatic enuresis(MEN): These kids have never had a dry period of >6 months and in the absence of any bladder dysfunction or symptoms suggestive of lower urinary tract issues
Non-monosymptomatic enuresis Nocturna(Non-MEN): diurnal presentation with an urge, frequency, and enuresis.
