Abstract:
During local small measles outbreak in Japan, 3 adolescents with febrile skin rash suspected as having measles were diagnosed with primary human herpesvirus (HHV)-7 infection. Primary HHV-7 infection can cause exanthem subitum in not only young children but also adolescents. HHV-7 should be considered as a possible causative agent for adolescent febrile skin rash during the measles outbreak.
Insights
Primary human herpesvirus (HHV)-7 infection can cause febrile skin rash in adolescents, not just young children. During a measles outbreak, HHV-7 should be considered a potential cause of adolescent rashes.
Area of Science:
- Infectious Diseases
- Virology
- Pediatrics
Background:
- Measles outbreaks pose a public health challenge, often leading to the misdiagnosis of other febrile illnesses.
