Measles: Incidence on the decline in Karnataka, but pockets in BBMP and Ballari record higher number of cases

Although the incidence of measles, a highly contagious viral infection, is on a decline in Karnataka, several pockets in Ballari and BBMP have been consistently reporting higher number of cases since 2024.
According to data from the State Health Department, the number of laboratory confirmed, clinically compatible and epi-linked measles cases reduced from 4,001 in 2023 to 1,115 in 2024. This year as of April 22, the State recorded 292 cases. Likewise, the number of rubella cases have also reduced from 237 in 2023 to 166 in 2024. This year (till April 22), the State has recorded 92 rubella cases.
In 2024, Ballari and BBMP recorded 243 and 103 measles cases respectively, the highest in the State. This year till April 22, these two districts recorded 91 and 25 cases respectively. While the highest number of rubella cases in 2024 have been reported in BBMP areas at 23, this year (till April 22) Yadgir has seen the highest at 15.
Outbreaks
The number of laboratory confirmed measles outbreaks decreased from 30 in 2023 to six in 2024 and three this year so far. An outbreak is defined as five or more cases, or any death, confirmed from a small geographical area over four weeks. The State has not seen any rubella outbreak since 2023, said Ansar Ahmed, State Project Director, Integrated Disease Surveillance Project (IDSP).
Measles and Rubella are highly infectious viral diseases that can lead to serious illnesses, lifelong complications, and even death. Due to their high infection rate, India has set a goal to eliminate these diseases by 2026.
National campaign
Union Health Minister J.P. Nadda on Thursday (April24, 2025) launched the National Zero Measles-Rubella Elimination campaign 2025-26, marking a significant step towards India's goal of eliminating measles and rubella by 2026.
In Karnataka, this year (January to April 22), three districts - Dakshina Kannada, Davangere and Kodagu - have reported zero measles cases and eight districts including Bagalkot, Belagavi, Bengaluru Urban, Kodagu and Koppal have recorded zero rubella cases, according to data.
Dr Ahmed said any person who is unvaccinated is susceptible. Children under five, pregnant women and persons with compromised immune systems are at higher risk of severe complications, he said.
MR vaccine
Under the Universal Immunization Programme (UIP), two doses of the Measles-Rubella (MR) vaccine are provided free of cost to all eligible children, at 9-12 months and 16-24 months of age, respectively. Currently, India's MR vaccination coverage stands at 93.7% for the first dose (2024-25 HMIS data) and 92.2% for the second dose.
Karnataka's MR vaccination coverage is 96% for the first dose (2024-2025 HMIS data) and 93% for the second dose. The vaccination coverage is the lowest in BBMP at 83% for the first dose and 81% for the second dose.
High-level committee
Attributing the high incidence of measles in BBMP to the low immunisation coverage, Harsh Gupta, Principal Secretary (Health), said the health monitoring structure in BBMP is weak due to various reasons. 'We have seen that BBMP reported the highest number of dengue cases last year,' he said.
'While primary health facilities in core BBMP areas are run and managed by the civic body, those in the new wards are managed with grants from the zilla panchayats and the Health Department. Apart from lack of coordination, the number of ASHAs and ANMs available are not proportionate to the population here. We are setting up a high-level committee to discuss the feasibility of either taking over BBMP-run facilities or handing over all the centres to BBMP. This will be sorted out in about two months and we will place a proposal before the cabinet,' Mr Gupta added.

Week-long immunisation drive to begin in Gurugram slums in late June

The district health department will launch a week-long immunization drive in late June, targeting children under five in slum clusters across the city. The campaign aims to deliver life-saving vaccines to vulnerable communities with limited healthcare access. While officials initially planned to focus on five major slums, the drive will now cover all informal settlements throughout Gurugram. According to health officials, the campaign will focus on vaccines under the National Immunisation Schedule, including those for polio, measles, diphtheria, tetanus, and hepatitis B. Accredited Social Health Activist (ASHA) and Anganwadi workers have already conducted door-to-door surveys to identify children who missed scheduled doses. 'This is a crucial opportunity for parents to ensure their children are protected from preventable but serious diseases. We request all guardians to bring their children to the nearby vaccination centres and be part of this important public health effort,' said Dr. Jaiprakash Rajliwal, deputy civil surgeon for Gurugram. Health workers will also conduct home visits in cases where children are unable to reach vaccination centres due to illness or other challenges. The department has compiled a list based on the surveys to ensure no eligible child is left behind. Dr Jaiprakash added that a child is considered fully immunised after receiving the BCG vaccine at birth (for tuberculosis), three doses of the oral polio vaccine (OPV 1, 2, and 3), three doses of the pentavalent vaccine (covering diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type B), and the Measles-Rubella (MR1) vaccine at nine months. Daily progress of the campaign will be monitored, and any gaps or lags in coverage will be addressed in real time. Officials said the initiative is part of a broader effort to boost immunisation rates and prevent disease outbreaks in high-density, low-income settlements.

State's maternal mortality ratio drops to all-time low of 18

Kerala's maternal mortality ratio (MMR) has dropped to an all-time low of 18 (per one lakh live births), according to the latest Sample Registration System (SRS) special bulletin on maternal mortality in India (2020-22), brought out by the office of the Registrar General of India. According to the SRS bulletin (2020-22), Kerala's MMR dropped two points from 20 in 2019-21 to the current level of 18. While the SRS figures will be quoted as the official stats, Health department officials point out that the figure cannot be further from reality, considering the fact that Kerala had lost 97 pregnant women to COVID during the survey period. Before the pandemic, Kerala had achieved an MMR of 30 by 2020, one of the U.N. Sustainable Development Goals, that too, one year ahead. However, during the second wave of COVID, the MMR rose significantly, almost doubling, when compared to the pre-pandemic levels. Health department's official figures say that the first two waves of COVID claimed 97 maternal lives in Kerala On an average, some 120-140 maternal deaths are annually reported in the State. But in 2021-22, the number of maternal ḍeaths rose to 220 on account of COVID. 'Kerala's MMR, according to the line list data the Health department collectS from districts and as reported in the HMIS (Health Management Information System) portal, rose sharply to 51 in 2021-22 because the number of maternal deaths shot up to 220. This dipped to 28 in 2022-23 as soon as COVID waves receded,' a senior Health official pointed out. Kerala's current MMR (2023-24), stands at 32, as per the Health department's stats, he added. While the SRS figures are arrived at using the sample survey system, the Health department goes by the actual line list of maternal deaths it gathers from districts and hence both figures are always at variance. Despite the variance in SRS data and the State Health department's data, Kerala, however continues to hold its prime position of having the lowest MMR, thanks to the targeted quality improvement initiatives it has implemented over the past decade or more to reduce maternal deaths. However, safe motherhood continues to be a goal that the State cannot take its eyes off because the last mile reduction of causes leading to maternal deaths has been getting increasingly difficult, given the changing lifestyle, higher age at parity and the rising burden of chronic conditions including obesity, diabetes and hypertension in women. 'Annual child births have been declining steadily in Kerala and as of 2023-24, we had just 3,74,078 child births (HMIS data). Given that MMR is calculated as a proportion of maternal deaths per 1,00,000 live births, our MMR figure is unlikely to dip further,' the official added
