Assessing afebrile malaria and bed-net use in a high-burden region of India: Findings from multiple rounds of mass screening.

A key obstacle in the fight against malaria is afebrile malaria. It remains undiagnosed and, therefore, is invisible to the health system. Apart from being a serious illness, it contributes to increased transmission. Existing studies in India have not adequately reported afebrile malaria and its determinants, including the use of long-lasting insecticide-treated nets (LLINs). This study used six waves of mass screening, which were conducted by the state government in the high-malaria-burden region of Chhattisgarh, a state in India, in 2020, 2021, and 2022. Each round of data collection included more than 15000 individuals. Descriptive statistics were used to analyse key indicators of malaria prevalence and LLIN use. Multivariate analyses were performed to identify the determinants of afebrile malaria and LLIN use. Malaria prevalence in the afebrile population varied from 0.6% to 1.4% across the different waves of mass screening. In comparison, malaria positivity among febrile individuals was greater than 33% in each wave. Afebrile malaria contributed to 19.6% to 47.2% of the overall malaria burden in the region. Indigenous communities (scheduled tribes) were more susceptible to malaria, including afebrile malaria. Individuals using LLINs were less likely to be affected by afebrile malaria. Overall, 77% of the individuals used LLINs in early monsoon season, and in winter the rate was lower at 55%. LLIN use was significantly associated with the number of LLINs the households received from the government. Although fever continues to be a primary symptom of malaria, afebrile malaria remains a significant contributor to the malaria burden in the region. The free distribution of LLINs should be expanded to include high-burden populations. Global policies must include strategies for surveillance and control of afebrile malaria in high-burden areas.

Out-of-Pocket Expenditure and Opportunity Cost of Leptospirosis Patients at a Tertiary Care Hospital of Gujarat, India.

INTRODUCTION: The study investigates the cost incurred by leptospirosis patients as either out-of-pocket expenditure (OOPE) or opportunity cost (OC) and recommends accordingly for the national program on leptospirosis in India. OBJECTIVES: The objective of this study is to determine leptospirosis-related OOPE and OC at a government tertiary care hospital and to disaggregate the total OOPE into contributing cost domains. MATERIALS AND METHODS: The OOPE data were collected by the personal interview of confirmed leptospirosis cases who took complete treatment at the hospital in year 2009 using a prestructured questionnaire. The patients were interviewed daily until discharge to know daily OOPE. RESULTS: The mean OOPE per patient was Rs. 2157/-, Median: Rs. 1880/-, 25th-75th percentile: Rs. 1446 - Rs 2587.5). The lowest quintile for OOPE was Rs. 1330/- and the highest quintile was Rs. 2874/-. Loss of daily wages was 68% (Rs. 1458.9/-) of the total OOPE. Other major expenditure included cost of drugs Rs. 308.8/- (14%), expenditure on food Rs. 173/- (8%), and travelling expenses Rs. 204.4/- (9%). CONCLUSIONS: Rs. 2157/- is significant OOPE, and hence, important factor in understanding health-seeking behavior and compliance of leptospirosis patients. The OC (loss of daily wages) amounts to 68% of total OOPE which has to addressed by the government to realize universal health coverage.
