Abstract:
In November 2017, eight confirmed measles cases were reported to Public Health England from a hospital in the West Midlands. A multidisciplinary Incident Management Team (IMT) was established to determine the extent of the problem and coordinate an outbreak response. Between 1 November 2017 and 4 June 2018, a total of 116 confirmed and 21 likely measles cases were linked to this outbreak; just under half (43%) were aged over 15 years of age. Fifty-five of the confirmed cases were hospitalised (48%) and no deaths were reported. At the start of the outbreak, cases were mostly individuals of Romanian origin; the outbreak subsequently spread to the wider population. Over the 8-month response, the IMT conducted the following control measures: extensive contact tracing, immediate provision of post-exposure prophylaxis, community engagement amongst specific high-risk groups, MMR awareness raising including catch-up campaigns and enhanced vaccination services at selected GP surgeries. Key challenges to the effective control measures included language difficulties limiting community engagement; delays in diagnosis, notification and appropriate isolation of cases; limited resources for contact tracing across multiple high-risk settings (including GPs and hospitals) and lack of timely data on vaccine coverage in sub-groups of the population to guide public health action.
Insights
A measles outbreak in the West Midlands affected 116 individuals, with challenges in control measures. Public health interventions included contact tracing and enhanced vaccination services.
Area of Science:
- Public Health
- Epidemiology
- Infectious Disease Control
Background:
- A measles outbreak was identified in November 2017 in the West Midlands.
- The outbreak initially involved individuals of Romanian origin before spreading to the wider population.
Purpose of the Study:
- To describe the epidemiology of a measles outbreak.
- To outline the control measures implemented by an Incident Management Team (IMT).
- To identify challenges faced during the outbreak response.
Main Methods:
- Confirmed and likely cases were identified and tracked.
- An Incident Management Team (IMT) coordinated control measures.
- Control measures included contact tracing, post-exposure prophylaxis, community engagement, and vaccination campaigns.
Main Results:
- A total of 116 confirmed and 21 likely measles cases occurred between November 2017 and June 2018.
- Nearly half of the cases (43%) were over 15 years old.
- 48% of confirmed cases required hospitalization; no deaths were reported.
Conclusions:
- The outbreak highlighted challenges in controlling infectious diseases in diverse populations.
- Effective control required addressing language barriers, improving diagnostic and notification timeliness, and enhancing vaccination data.
- Multidisciplinary collaboration and targeted public health interventions are crucial for managing outbreaks.
