[Health Channel/Comprehensive Report]My 1-year-old brother suddenly found a high fever (39.2°C) and convulsions at home. The parents urgently contacted 119. The emergency physician judged that it was different from typical heat convulsions. The follow-up examination report of cerebrospinal fluid was: HHV- 6. Human herpes virus type 6, which is one of the viruses that cause “infantile roseola”.

Wu Changteng, the attending physician of Pediatric Emergency Department of Chang Gung Memorial Hospital in Linkou,Talking about 543 of Pediatric Emergency – Dr. Wu ChangtengThe article stated that the younger brother was sent to the pediatric emergency department by 119, and the spasm continued, so he stabilized the vital signs and gave oxygen. Stop, estimating that the cramps lasted about 30 minutes, so his gut feeling wasn’t the same as a typical heat cramp.

Subsequently, “HHV-6”, which is the human herpes virus type 6, was detected from the cerebrospinal fluid of the younger brother, which is one of the viruses that cause “infantile roseola”. Sure enough, on the 4th day of hospitalization, my brother’s fever subsided, and roseola developed. It can be determined that the younger brother was infected with HHV-6 infection. In addition to high fever and infant roseola, encephalitis was also complicated, which caused convulsions.

Wu Changteng explained that roseola is a skin manifestation caused by viral infection, and human herpesvirus type 6 (HHV-6) and human herpesvirus type 7 (HHV-7) are the most common. Roseola may occur throughout the year, with the highest incidence in spring and autumn. It is mainly transmitted by droplets. The virus exists in the saliva of healthy adults and enters the body of infants and young children through the oral cavity, nasal cavity or conjunctival mucosa, and then develops the disease. It is characterized by a high fever above 39°C for 3-5 days, followed by a sudden resolution of the fever, followed by a skin rash. Because it is a rose-like rash that usually occurs in infants under 2 years of age, it is named infantile roseola.

Wu Changteng said that the seroprevalence of HHV-6 in children 2 years and older reaches >80%. Neurological complications of primary HHV-6 infection include febrile cramps, which are observed in 13% of infected children. Sometimes these seizures may differ from febrile cramps that accompany other infections because they are usually localized or prolonged. HHV-6 is the virus most commonly associated with febrile cramps in the 1/3 of all first febrile cramps.

Wu Changteng pointed out that in a European study, HHV-6 was isolated in 35% of children with febrile cramps. In severe cases, a small number of patients occasionally develop encephalitis, including cerebellar encephalitis and rhomboencephalitis! Although HHV-6 is a rare cause of encephalitis in children, when it occurs with cerebral edema, it can be fatal, even in immunocompetent children, and a good prognosis depends on a positive response to cerebral edema treat.
