Impact of awareness campaigns on Acute Encephalitis Syndrome in Northern India

Abstract

Abstract Introduction Acute encephalitis syndrome (AES), is a major public health problem in northern India. To meet with the growing concerns of death and disability outcomes of the disease, the Government launched an ambitious awareness campaign in collaboration with the UNICEF. The campaign known as “dastak” comprised of intersectoral convergence for coordinated preventive activities along with widespread door to door awareness programme and envisaged reducing the morbidity and mortality associated with the disease. Methods This is a record based retrospective study conducted in the state of Uttar Pradesh, India. Line list of patients suffering from AES, from the year 2016 to 2019, was used to determine number of cases, deaths, case fatality rate, and age group affected. In addition, the time lag between onset of symptoms and hospital admission as well as duration of hospital stay was also calculated. The data were analysed using Statistical Package for Social Sciences (SPSS) version 24.0. Results Analysis of data revealed that, in the year 2016 and 2017, there were 8635 reported cases of AES out of which 1296 patients died of the disease. During this period average CFR was 15%. However, after launch of intersectoral preventive and awareness campaign the total number of AES cases dropped to 5262 (3077 cases in 2018 and 2185 cases in 2019) with 374 deaths and an overall CFR of 7.11% during this period. Children are more commonly affected than adults with average age of AES patients being 10.29 and the most commonly affected age group being 1 to 5 years. After introduction of the campaign there was a decrease in mean (± SD) duration between onset of symptoms and hospital admission from 2.20 (± 1.64) to 1.02 (± 0.41) days. Similarly mean (± SD) duration of hospital stay decreased from 7.64 (± 10.83) to 5.6 (± 6.9) days. Conclusions Since the introduction of preventive and awareness campaign there has been a significant reduction in morbidity and mortality associated with AES. Key messages Impact assessment of preventive activities and awareness campaign on disease helps in making policy decisions and future plan of action for fight against the Acute encephalitis syndrome. Acute encephalitis syndrome is a major public health problem in northern India and early recognition and treatment significantly affects its outcome.
