Summary
Disseminated herpes simplex virus-1 (HSV-1) is rare in immunocompetent children. This case shows a 5-year-old boy with disseminated HSV-1, multiorgan failure, and DIC, who recovered well with acyclovir treatment.
Area of Science:
- Virology
- Pediatric Infectious Diseases
- Immunology
Background:
- Disseminated herpes simplex virus-1 (HSV-1) infections typically occur in neonates or immunocompromised individuals.
- HSV-1 is a common viral infection, but severe, disseminated forms are infrequent in healthy children.
Observation:
- A 5-year-old immunocompetent male presented with fever and seizures.
- The patient subsequently developed multiorgan failure and disseminated intravascular coagulation (DIC).
Findings:
- Diagnosis of disseminated HSV-1 infection was confirmed.
- The child experienced an excellent clinical outcome following treatment with intravenous acyclovir.
Implications:
- This case highlights that disseminated HSV-1 can occur in immunocompetent children, challenging typical clinical presentations.
- Early recognition and prompt antiviral therapy with acyclovir are crucial for favorable outcomes in severe HSV-1 infections.
- Further research may elucidate specific host factors contributing to severe HSV-1 in immunocompetent pediatric populations.

Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
