Insights
A cluster of invasive group A streptococcal sepsis cases, including one fatality, occurred in children with chickenpox. Public health measures and varicella vaccination are crucial for prevention.
Area of Science:
- Infectious Diseases
- Pediatrics
- Public Health
Background:
- Invasive group A streptococcal sepsis is a known complication of primary chickenpox.
- Prompt and aggressive treatment is essential for invasive group A streptococcal sepsis.
- Chickenpox can lead to severe outcomes, including sepsis and death.
Purpose of the Study:
- To report the first epidemiologically linked cluster of invasive group A streptococcal sepsis following chickenpox in the UK.
- To highlight the importance of public health interventions in managing infectious disease outbreaks.
- To emphasize the role of varicella vaccination in preventing severe outcomes of chickenpox.
Main Methods:
- Case reporting and epidemiological investigation of linked infections.
- Review of clinical data for patients with invasive group A streptococcal sepsis and chickenpox.
- Analysis of public health measures implemented following the outbreak.
Main Results:
- Two cases of invasive group A streptococcal sepsis were identified in children with primary chickenpox.
- One fatality occurred, emphasizing the severity of the complication.
- The cases were linked to attendance at the same preschool, indicating potential transmission.
Conclusions:
- Epidemiologically linked cases of invasive group A streptococcal sepsis following chickenpox can occur in pediatric populations.
- Public health measures are vital to control the spread of secondary bacterial infections after viral illnesses.
- Varicella vaccination is a key strategy to reduce the incidence of chickenpox and its severe complications, including sepsis.
Abstract:
We report the first reported cases of epidemiologically linked invasive group A streptococcal septicaemia, with one fatality, following primary chickenpox infection in previously fit and well children who attended the same preschool. Invasive group A streptococcal sepsis is a well documented complication of chickenpox, which requires prompt and aggressive treatment. Following the cluster, public health measures were put in place to prevent further disease. Varicella vaccination has been shown to significantly reduce hospital admissions as well as deaths related to chickenpox infection. This is the first reported cluster of two epidemiologically linked patients in the UK.
