Spatial Mapping of Measles-Rubella Campaign in a Rural Area near Bengaluru, Karnataka, India

Immunization is animportant public health intervention.The Measles-Rubella (MR) campaign was launched during 2017in India for the elimination of measles.This study explored vaccination coverageandspatialmapping using QGIS and Google Earth Pro. WHO-EPI30 clusters sampling technique for evaluation of vaccination coverage was performed in villages within the rural area of a Medical College nearBengaluru.Seven children aged 2-15 years were surveyed per cluster, resulting in 210 children. Smartphones having GPS/Garmin GPS72H (handheld GPS receiver)were used for noting coordinates. Subsequently all these coordinates were plottedfor spatial mapping of vaccination coverage. The geospatial characteristics of the households surveyed were described using spatial mapping. Results indicate that 87.6% were immunized with MR Vaccine under the campaign, but 12.4% remained unimmunized, the reasons given being absence, ignorance, or refusal because of rumours concerning side-effects.The Measles-Rubella campaign coverage was found to be satisfactory. In addition the spatial mapping is a useful tool for measurement of coverage of a vaccination campaign. There was no clustering of unimmunized subjects observed on spatial mapping.

Global positioning system & Google Earth in the investigation of an outbreak of cholera in a village of Bengaluru Urban district, Karnataka.

Background & objectives: The global positioning system (GPS) technology along with Google Earth is used to measure (spatial map) the accurate distribution of morbidity, mortality and planning of interventions in the community. We used this technology to find out its role in the investigation of a cholera outbreak, and also to identify the cause of the outbreak. Methods: This study was conducted in a village near Bengaluru, Karnataka in June 2013 during a cholera outbreak. House-to-house survey was done to identify acute watery diarrhoea cases. A hand held GPS receiver was used to record north and east coordinates of the households of cases and these values were subsequently plotted on Google Earth map. Water samples were collected from suspected sources for microbiological analysis. Results: A total of 27 cases of acute watery diarrhoea were reported. Fifty per cent of cases were in the age group of 14-44 yr and one death was reported. GPS technology and Google Earth described the accurate location of household of cases and spot map generated showed clustering of cases around the suspected water sources. The attack rate was 6.92 per cent and case fatality rate was 3.7 per cent. Water samples collected from suspected sources showed the presence of Vibrio cholera O1 Ogawa. Interpretation & conclusions: GPS technology and Google Earth were easy to use, helpful to accurately pinpoint the location of household of cases, construction of spot map and follow up of cases. Outbreak was found to be due to contamination of drinking water sources.

Prevalence of Chronic Obstructive Pulmonary Disease and its Association with Tobacco Smoking and Environmental Tobacco Smoke Exposure among Rural Population.

A fi eld survey was conducted for chronic obstructive pulmonary disease (COPD) epidemiology in the rural fi eld practice area of Kempegowda Institute of Medical Sciences, Bangalore, India, which covers a population of 44,387 to fi nd out the prevalence of COPD in adult subjects of 35 years and above using cluster sampling technique and to determine the association of tobacco smoking, environmental tobacco smoking (ETS) exposure and type of cooking fuel used with COPD. The overall prevalence of COPD was 4.36%. The prevalence among males and females were 5.32% and 3.41% respectively. The prevalence was found to be increasing with an increase in age. The tobacco smoke and exposure to ETS was signifi cantly associated with higher odds of COPD with adjusted odds ratio 2.97 and 2.67 respectively. Thus, there was a signifi cant association between tobacco smoking and ETS exposure with COPD.

Rural Rabies Prevention Project - A ‘One Health’ Experiment in India: An Overview.

Aim: To assess the feasibility of implementing "one health approach" to prevent human rabies and control animal rabies in a rural community. Study Design: Health services research in a rural setting. Place and Duration of Study: A medical college and a veterinary college along with an animal welfare organization delivered a wide array of "integrated services" in three villages' i.e. Kumbalagodu, Thagachikuppe and Gerupalya near Bangalore, India comprising a population of 10,220 persons for a period of two years from December, 2009 to November, 2011. The nearby three villages of Ramohally, Vinayakanagara and Bhimanakuppe with a population of 6,023 persons formed the control group, with no project inputs. Methodology: This consisted of household surveys at the beginning and end of two years ; rabies awareness campaigns; clinical and laboratory surveillance of rabies in dogs; rabies post-exposure prophylaxis (PEP) in humans; pre-exposure rabies prophylaxis (PrEP) by intradermal route in school children, pet dog owners and veterinarians ; mass dog vaccination and deworming; and sero-surveillance in both dogs and humans. Results: The ratio of veterinary and medical manpower in study villages was 1: 11 and dog to human ratio was 1: 23.The information, education and communication materials developed and used were domestic outdoor wall writings (11), domestic indoor annual wall calendar (2000), school book labels (1000); game charts (16); wall posters (65); flip chart (15); rabies educational DVD (1). There were 102 local cable television transmissions on rabies prevention. 69 persons received rabies PEP. PrEP was given to 368 school children, pet dog owners and veterinarians. Sixty one human serum samples were analyzed by rapid fluorescent focus inhibition test for rabies antibody detection. Sixteen veterinarians were trained to use direct rapid immunohistochemical test (dRIT) for rabies diagnosis. Six ruminants were confirmed rabid by dRIT. There were no cases of human rabies. The cost of entire project was US $ 85,958. Conclusion: A blend of medical, veterinary and animal welfare services were successfully delivered through a "one health" approach. Based on this success a "conceptual model" was evolved to propagate its replication in other rural communities across India.

Prevalence of domestic accidents in the rural field practice area of a medical college in Bangalore, Karnataka.

Domestic accidents are worldwide health problems. A cross-sectional study was conducted in the rural field practice area of Kempegowda Institute of Medical Sciences, Bangalore. A total of 5419 individuals were selected from 30 clusters (villages) using cluster sampling technique. Of the 5419 study population, 50.9% (2748) were males and the rest were females. The prevalence of domestic accidents in the rural community was found to be 9.6% (522 individuals who had sustained domestic accidents), was found to be more in females compared with males, which was statistically significant with P-value =0.0077 (Z value =9.09). Falls 43% (225) was the most common type of domestic accidents. The most common place of occurrence of domestic accidents was 46% (243) kitchen, most frequent site of injures in domestic accidents was upper limbs.
