Measles Outbreak in North London: Cases Rise, Vaccination Rates Lag

A measles outbreak is currently affecting North London, with Enfield emerging as the primary epicenter. As of March 2, 2026, Enfield accounted for 34% of the 235 measles cases reported in England this year, raising concerns among health officials. The outbreak underscores the critical importance of vaccination, as lower vaccination rates contribute to the resurgence of this highly contagious disease.

Current Situation in Enfield and Haringey

Enfield has recorded at least 80 measles cases since the start of 2026, with nine additional infections reported as of last week. Neighboring Haringey has seen 15 cases reported this year. Together, these two boroughs account for 95 of the 146 total cases recorded in London. The UK Health Security Agency (UKHSA) notes that reported figures likely underestimate the actual number of infections due to reporting lags. Source

Vaccination Rates and Vulnerable Groups

The measles vaccination rate in Enfield is 64.3%, significantly lower than the national average of 83.7%. This disparity is a key factor driving the outbreak. The outbreak is primarily affecting children in schools and nurseries, with the most severe cases – those requiring hospitalization – linked to unvaccinated individuals.

Children under one year old account for 12.8% of cases. Source

Broader Concerns and Potential Stabilization

Health experts warn that the decline in vaccination rates in Enfield could signal a broader risk for other areas of London. Addressing health inequalities and improving vaccine uptake are crucial to preventing further outbreaks. Factors contributing to lower vaccination rates in Enfield include high levels of social deprivation and a greater population density of children and young people in poorer neighborhoods. Source

Even as the situation remains dynamic, there are indications the outbreak may be stabilizing. As of March 5, 2026, eight cases were recorded in London during the week ending February 23, followed by only two cases in the week ending March 2.
