The latest weekly laboratory-confirmed measles cases in England, as reported by UKHSA, are published:

Thursday 18 April 2024

The latest number of laboratory confirmed measles cases in England have been published in an updated  by UKHSA.

Since the last update a week ago, a further 86 laboratory confirmed measles cases have been confirmed in England, bringing the total number of cases confirmed since 1 October 2023 to 1109.

The rapid increase in cases seen in late 2023 was initially driven by a large outbreak in Birmingham but activity there has now stabilised and in more recent weeks we have seen a rise in cases in London and smaller clusters ongoing in other regions.

In the 4 weeks since 18 March 2024, there have been 191 laboratory confirmed measles cases. 39.8% of cases were in London (76 of 191), with the West Midlands accounting for a quarter of cases (25.1%, 48 of 191). Around 12% of cases (23 of 191) were in the East Midlands.

Since 1 October, in England there have been 1109 laboratory confirmed measles cases:

• 17 cases were reported in October 2023
• 41 in November 2023
• 153 in December 2023
• 274 in January 2024
• 253 in February 2024
• 299 in March 2024
• 72 (to date) in April 2024

48.2% (535 of 1109) of these cases have been in the West Midlands, 24.3% (269 of 1109) in London and 9.5% (105 of 1109) in the East Midlands. The remaining cases were reported in other regions of England.

The majority (706 of 1109, 63.7%) of these cases were in children aged 10 years and under, and 28.8% (319 of 1109) in young people and adults aged 15 years and over.

The data published in this epidemiological overview covers the period between 1 October 2023 and 15 April 2024 and is currently provisional, with the number of cases for the most recent months likely to adjust as more suspected cases undergo confirmatory testing and data cleansing.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

Numbers of measles cases are rising across the country, with a particular increase seen in London in recent weeks.

We know some communities in London have very low MMR vaccination rates. Measles is extremely infectious and it only takes one case to get into these communities for this disease to spread rapidly, especially in schools and nurseries.

The MMR jab offers the best protection against measles. Measles is preventable but many thousands of children around the country are still not fully vaccinated and may be at risk of serious illness or life-long complications. No parent wants this for their child.

Epidemiological updates will continue to be published every Thursday. Data included in this report are provisional and subject to change as more suspected cases undergo confirmatory testing and some locally tested cases are discarded after obtaining further epidemiological information or undergoing confirmatory testing at the reference laboratory.

Thursday 11 April 2024

The latest number of laboratory confirmed measles cases in England have been published in an updated  by UKHSA.

Since the last update a week ago, there have been a further 89 laboratory confirmed measles cases in England, bringing the total number confirmed since 1 October 2023 to 1023.

Although the ongoing outbreak in the West Midlands initially drove the increase in cases, this week’s data showed that London had the greatest number of new confirmed cases, with smaller clusters ongoing in the East Midlands and the North West.

In the 4 weeks since 11 March 2024, there have been 195 laboratory confirmed measles cases. 69 of these (35%) were reported from London, 62 (32%) from the West Midlands, and 23 (12%) from the East Midlands. Confirmed cases have been reported in all regions during this period.

Since 1 October in England there have been 1023 laboratory confirmed measles cases:

• 17 cases were reported in October 2023
• 41 in November 2023
• 154 in December 2023
• 277 in January 2024
• 248 in February 2024
• 272 in March 2024
• 14 (to date) in April 2024

51% (520 of 1023) of these cases have been in the West Midlands, 23% (232 of 1023) in London, and 9% (92 of 1023) in the East Midlands. The remaining cases were reported in other regions of England.

The majority (64%) of these cases were in children aged 10 years and under. 29% were in people aged 15 years and over.

The data published in this epidemiological overview covers the period between 1 October 2023 and 9 April 2024 and is currently provisional, with the number of cases for the most recent months likely to adjust as more suspected cases undergo confirmatory testing and data cleansing.

Dr Rob Verrecchia, UKHSA Health Protection Consultant, said:

We are continuing to see measles cases right across the country, with cases particularly high in London and the West Midlands. Measles is an extremely infectious disease, and it only takes one case to get into a community with low vaccination rates for measles to spread rapidly, especially in schools and nurseries, so it is vital that people are fully protected by two doses of the MMR vaccine. Measles is completely preventable with vaccination, but many thousands of children around the country are still not fully vaccinated and are at risk of serious illness or life-long complications. That is why our campaign is reminding parents of the importance of ensuring their children are vaccinated.

Epidemiological updates will continue to be published every Thursday.

Since the last update a week ago, there have been a further 66 laboratory confirmed measles in England, bringing the total number of cases confirmed since 1 October 2023 to 934.

Although the outbreak in the West Midlands initially drove the increase in cases, in recent weeks there has been an increase in activity in London, with smaller clusters ongoing in the East Midlands and the North West.

In the 4 weeks since 4 March 2024, there have been 190 laboratory confirmed measles cases. The highest number of cases were reported from the West Midlands (67 of 190, 35%), London (63 of 190, 33%) and the East Midlands (21 of 190, 11%). During this period, all regions have had confirmed cases.

Since 1 October in England there have been 934 laboratory confirmed measles cases:

• 17 cases were reported in October 2023

• 153 in December 2023
• 269 in January 2024
• 231 in February 2024

The majority (587 of 934, 63%) of these cases were in children aged 10 years and under and 29% (275 of 934) in young people and adults aged 15 years and over.

The data published in this epidemiological overview covers the period between 1 October 2023 and 2 April 2024 and is currently provisional, with the number of cases for the most recent months likely to adjust as more suspected cases undergo confirmatory testing and data cleansing.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

We are continuing to see measles cases in all regions of England, with cases particularly high in the West Midlands and London, so it is vital that people are fully protected by two doses of the MMR vaccine. It only takes one case to get into a community with low vaccination rates for measles to spread rapidly, especially in schools and nurseries. We know that hundreds of thousands of children around the country, particularly in some inner-city areas are still not fully vaccinated and are at risk of serious illness or life-long complications but measles is completely preventable with vaccination.

Since the last update a week ago, a further 59 laboratory confirmed measles cases have been confirmed in England, bringing the total number of cases confirmed since 1 October 2023 to 789.

Although the outbreak in the West Midlands initially drove the increase in cases, activity there is now on a downward trend. In recent weeks, small clusters of cases have emerged in other regions such as London and the North West.

In the 4 weeks since 19 February 2024, there have been 158 laboratory confirmed measles cases. The West Midlands accounted for the majority of these (41%, 64 of 158), 27% (43 of 158) of cases have been in London, 10% (15 of 158) in the East Midlands, 7% in the North West (11 of 158) and 6% (9 of 158) in Yorkshire and the Humber.

Thursday 14 March 2024

The latest number of laboratory confirmed measles cases in England have been published in an updated  by UKHSA.

Since the last update a week ago, a further 52 laboratory confirmed measles cases have been confirmed in England. However, due to a routine retrospective data cleaning exercise in week 10 of 2024, 34 previously confirmed cases (since 1 October 2023) have been discarded in addition to 21 cases that had been erroneously reported. This brings the total number of cases confirmed since 1 October 2023 to 730.

Further revisions are expected while we continue to publish timely provisional data on a weekly basis to help monitor the current outbreak.

Although the outbreak in the West Midlands initially drove the increase in cases, activity there is now on a downward trend. In recent weeks, small clusters of cases have emerged in other regions such as London and the North West.

In the 4 weeks since 12 February 2024, there have been 151 laboratory confirmed measles cases. The West Midlands accounted for the majority of these (41%, 62 of 151), 26% (39 of 151) of cases have been in London, 12% (18 of 151) in the North West, 7% in Yorkshire and the Humber (11 of 151) and 7% (10 of 151) in the East Midlands. 

Since 1 October in England there have been 730 laboratory confirmed measles cases, 17 cases were reported in October, 42 in November, 156 in December 2023, 267 in January, 213 in February and 35 so far in March 2024. 60% (438 of 730) of these cases have been in the West Midlands, 18% (131 of 730) in London and 7% (48 of 730) in Yorkshire and the Humber. The remaining cases were reported in other regions of England.

The majority (462 of 730, 63%) of these cases were in children under the age of 10 and 29% (213 of 730) in young people and adults over the age of 15.

Since the last update a week ago, a further 83 laboratory confirmed measles cases have been confirmed in England. This brings the total number of cases confirmed since 1 October 2023 to 733.

Although the outbreak in the West Midlands initially drove the increase in cases, clusters of cases in other regions such as the North West have continued to increase in the past weeks.

In the 4 weeks since 5 February 2024, there have been 192 laboratory confirmed measles cases. The highest number of cases continue to be reported in the West Midlands (34%, 66 of 192) although case numbers in that region have now stabilised at a high level. 21% (41 of 192) of cases have been reported in the North West, 19% (39 of 192) in London, 13% in the East Midlands (25 of 192) and 7% (13 of 192) in Yorkshire and the Humber.

The majority (462 of 733, 63%) of these cases were in children under the age of 10 and 29.5% (216 of 733) in young people and adults over the age of 15.

The data published in this epidemiological overview covers the period between 1 October 2023 and 4 March 2024 and is currently provisional, with the number of cases for the most recent months likely to increase as more suspected cases undergo confirmatory testing.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

Worryingly we are continuing to see an increase of measles cases in some areas, most recently in parts of the North-West, where we know MMR vaccine uptake is low.

Parents are already coming forward to take up the offer of the MMR vaccine for their children, but 100s of thousands of unvaccinated children are at risk of serious illness or life-long complications. The disease spreads very easily among those who are unvaccinated, especially in schools and nurseries, however measles is completely preventable with vaccination.

Although the outbreak in the West Midlands initially drove the increase in cases, clusters of cases in other regions have continued to increase in the past week.

In the 4 weeks since 22 January 2024, there have been 169 laboratory confirmed measles cases. The West Midlands accounted for the majority of these (47%, 79 of 169), mostly in Birmingham, although case numbers in that region appear to be stabilising. 

14% (23 of 169) of cases have been in London, 14% (23 of 169) in the North West, 11% in the East Midlands (18 of 169) and 10% (16 of 169) in Yorkshire and the Humber.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

As expected, due to worryingly low MMR vaccine uptake in some areas across the country, we are now starting to see clusters of cases in other regions. We’re urging parents to protect their children from this serious illness with the MMR vaccine before it spreads further.  

Parents are already coming forward to take up the offer of the MMR vaccine for their children, but 100s of thousands of unvaccinated children are at risk of serious illness or life-long complications. The disease spreads very easily among those who are unvaccinated, especially in schools and nurseries, however measles is completely preventable with vaccination.

Thursday 15 February 2024

The latest number of laboratory confirmed measles cases in England have been published in an updated   by UKHSA.

Since the last update a week ago, a further 56 laboratory confirmed measles cases have been confirmed in England, compared to 118 cases confirmed in the previous two weeks. This brings the total number of cases confirmed since 1 October 2023 to 521.

Although the initial outbreak in the West Midlands has driven the increase in cases, we are now starting to see clusters of cases in other regions.

In the 4 weeks since 15 January 2024, there have been 166 laboratory confirmed measles cases. The West Midlands accounted for the majority of these (55%, 91 of 166), mostly in Birmingham, although case numbers in that region appear to be stabilising. 

12% (20 of 166) of cases have been in London, 10% (17 of 166) in the North West, 10% in Yorkshire and the Humber (16 of 166) and 9% (15 of 166) in the East Midlands. 

Since 1 October in England there have been 521 laboratory confirmed measles cases, 17 cases were reported in October, 42 in November, 160 in December 2023, 252 in January and 50 so far in February 2024. 69 % (358 of 521) of these cases have been in the West Midlands, 14 % (71 of 521) in London and 7 % (37 of 521) in Yorkshire and The Humber. The remaining cases were reported in other regions of England.

The majority (343 of 521, 66 %) of these cases are in children under the age of 10 and 25% (133 of 521) in young people and adults over the age of 15.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

As expected, due to worryingly low MMR vaccine uptake in some areas across the country, we are now starting to see clusters of cases in other regions.

While parents are coming forward to take up the offer of the MMR vaccine for their children, there are still 100s of thousands of children who remain unprotected and therefore remain at risk of serious complications or life-long disability.

Measles spreads very easily among those who are unvaccinated, especially in nurseries and schools. People in certain groups, including babies, pregnant women, and people with weakened immunity, are at increased risk of complications from measles.

The data published in this epidemiological overview covers the period between 1 October 2023 and 13 February 2024 and is currently provisional, with the number of cases for the most recent months likely to increase as more suspected cases undergo confirmatory testing. Updates will be published every Thursday.

Thursday 8 February, 2024

The latest number of laboratory confirmed measles cases in England have been published in an updated published by UKHSA.

Since the last update a week ago, a further 118 laboratory confirmed measles cases have been confirmed in England, bringing the total number of cases confirmed since 1 October 2023 to 465.

A disproportionately high rate continues to be seen in the West Midlands, with a sharp rise in case numbers over the last 6 weeks, mainly driven by cases in Birmingham.

In England, 17 cases were reported in October, 42 in November, 161 in December, 240 in January 2024 and 5 in February. 71% (329 of 465) of these cases have been in the West Midlands, 13% (62 of 465) in London and 7% (32 of 465) in Yorkshire and The Humber. The remaining cases were reported in other regions of England.

The majority (306 of 465, 66%) of these cases are in children under the age of 10 and 25% (115 of 465) in young people and adults over the age of 15.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

The measles outbreak in the West Midlands continues to be a concern. MMR vaccine uptake has been falling over the last decade with 1 out of 10 children starting school in England not protected. Measles is highly infectious and there is a real risk it will spread to other areas.

Parents should be aware that measles is a nasty illness for most children and sadly for some can be very serious and life changing, but it is completely preventable.

The data published in this epidemiological overview covers the period between 1 October 2023 and 6 February 2024 and is currently provisional, with the number of cases for the most recent months likely to increase as more suspected cases undergo confirmatory testing. Updates will be published every Thursday.

Tuesday 30 January 2024

The latest number of laboratory confirmed measles cases in England have been published by the UKHSA in an .

From 1 October 2023, there have been 347 laboratory confirmed measles cases reported in England, with 127 of these cases confirmed in January 2024.

75% (260 of 347) of these cases have been in the West Midlands, 13% (46 of 347) in London and 7% (24 of 347) in Yorkshire and The Humber.

The majority (233 of 347, 67%) of these cases are in children under the age of 10 and 24% (85 of 347) in young people and adults over the age of 15.

Dr Vanessa Saliba, UKHSA Consultant Epidemiologist, said:

The ongoing measles outbreak in the West Midlands remains a concern. MMR vaccine coverage has been falling for the last decade with 1 out of 10 children starting school in England not protected and so there is a real risk that this outbreak could spread to other towns and cities.

The data published in this epidemiological overview covers the dates between 1 October, 2023 and 23 January, 2024 and is currently provisional. Updates will be published every Thursday going forward.
