Measles outbreak warning for India as cases rise in region

A letter published in The BMJ has warned that the measles outbreak in Bangladesh is a warning for India, after India reportedly recorded about 26,000 measles cases during the first half of 2026, more than the about 18,800 cases reported through all of 2025. The letter responds to a BMJ report on the Bangladesh outbreak and argues that neighbouring India still faces measles transmission despite progress in immunisation.

Bangladesh's measles outbreak has been severe. A BMJ news report published on 12 October 2026 said the country's measles death toll could be as high as 1,144, with most of those who died being children. A government update on 8 October showed 201,625 suspected measles cases and 22,116 confirmed cases since mid-March. The letter writers say that scale of transmission in a neighbouring country matters for India, given cross border movement and shared immunity gaps.

Measles outbreak exposes gaps behind national averages

The letter says India measles cases keep appearing because high national averages can hide large gaps at district and community level. WHO and UNICEF estimates cited in the letter put India's first dose measles containing vaccine coverage at about 98% in 2025 and second dose coverage at about 95%. The letter argues that stopping transmission needs at least 95% two dose coverage in every district and community, rather than nationally alone.

Recent outbreaks named in the letter show where those gaps sit. In Kozhikode, Kerala, 161 confirmed cases and one death were reported by mid-October 2026. In remote tribal settlements in Balaghat, Madhya Pradesh, clusters of childhood deaths linked to measles like illness, malnutrition and delayed access to healthcare were reported. The letter says migrant populations, geographically isolated communities and socioeconomically disadvantaged children remain at higher risk.

Measles outbreak response needs local coverage, letter says

The letter does not claim that India faces the same scale of outbreak as Bangladesh. It says the Bangladesh measles outbreak shows what can happen when routine immunisation weakens and immunity gaps widen. In Bangladesh, measles vaccine coverage fell from about 90% in 2020 to roughly 57% in 2025, according to a separate analysis in the International Journal of Infectious Diseases, and no nationwide follow up campaign had run since 2020.

For India, the letter's point is about measles vaccination reaching every community. National coverage figures look strong, but the letter says recurrent outbreaks show that averages conceal pockets of children with no dose or too few doses. Closing those pockets, through routine immunisation, catch up drives and rapid outbreak response in affected districts, is presented as the work that keeps a regional measles outbreak from becoming a wider one. The letter is an opinion piece addressed to the editor, not a new study, and its case figures are reported figures rather than verified counts from a single official release.

The letter also notes that India measles cases are not the only signal. A separate outbreak report counted India among the countries reporting the most measles cases between March and August 2026, with 18,863 cases in that window, behind Bangladesh at 65,439 and Indonesia at 46,578. That count covers a different period from the letter's first half figure, so the two numbers do not match exactly, but both point the same way: transmission continues even where national measles vaccination coverage looks high. Bangladesh measles trends and India measles cases together show why the letter calls for district level cover rather than reliance on a national average. A measles outbreak moves fast through unvaccinated children, so the letter argues that waiting for a measles outbreak to appear before acting leaves the response behind the spread.
