Background: Measles, a vaccine-preventable viral illness, continues to remain an important cause of mortality and morbidity worldwide. However, the last few years have seen a surge in cases of measles all over the world. This has been largely attributed to reduced vaccination coverage due to COVID 19 lockdowns, overcrowded neighbourhoods, unhygienic living conditions and other factors. Methods: An observational prospective study was carried out at a tertiary care hospital in northern India to study the clinico-demographic profile of patients with measles and to observe the factors associated with the disease.79 patients with measles were included in the study after taking consent from their parents. Detailed history was taken and assessment for nutritional status was done. The data was analyzed and descriptive statistics were presented using percentages. Results: During the study, a prevalence of 1.34% was reported for measles, with maximum cases in March (36.7%). The most common age group affected was ≤5years with male preponderance in all age groups.Also majority of measles cases belonged to lower middle (30.3%) socioeconomic class households and affected children were mostly malnourished. Majority of the patients were unimmunised (60.7%) against measles. The most common reason cited for not vaccinating the child was lockdown due to COVID 19 (56.7%). Conclusion: Unimmunisation, malnutrition and low socioeconomic status were found to be associated with measles. Higher incidence of measles in children who were not adequately immunised or unimmunised because of COVID 19 pandemic points towards an urgent need to boost immunization coverage for an efficient control of measles.
