The number of measles cases in north London continues to rise, sparking concern for neighbouring areas in Essex.

The UK Health Security Agency (UKHSA) has confirmed 50 cases in Enfield up to 16th February, predominantly affecting unvaccinated young children.

Due to laboratory testing delays, actual case numbers may be higher, according to UKHSA.

Between 1st January and 16th February, 130 confirmed cases occurred across England, an increase of 34 from UKHSA's last report.

This outbreak has impacted schools and nurseries significantly and caused hospital admissions in some instances.

Dr Vanessa Saliba from UKHSA stated that most affected are unvaccinated children under 10.

She emphasized the importance of the MMRV vaccine in preventing measles and protecting vulnerable children who cannot be vaccinated.

Measles, an infectious viral illness, can lead to severe complications such as pneumonia and brain inflammation.

Several jurisdictions have issued advisories for parents to check their children's vaccination status.

Southend City Council warns that rising cases in Enfield are likely to reach areas such as Essex, Southend, and Thurrock, urging parents to ensure vaccination.

This surge follows a World Health Organisation (WHO) declaration in January that the UK no longer has measles eliminated status.

Vaccination rates have plateaued, contributing to increased cases, notably 3,681 reported in the UK in 2024.

Latest figures show that only 91.9% of five-year-olds in England had one MMR vaccine dose in 2024/25, unchanged from previous years, with 83.7% having received both doses, marking a decline compared to past data.
