Characteristics of the sample population.
<p>Types I, II and III villages have <100, 100–250 and >250 houses respectively. The percentages in each case were calculated relative to the total population in each type of village. For the snakebite prevalence the percentages indicate the % of the male, female and total population in each village type who suffered snakebites and who died due to snakebite. This data was obtained from the 30 sampling villages.</p
Correlation between rainfall and snakebite incidence.
<p><i>A</i>. Annual snakebite incidence (blue bars) and rainfall statistics (red line) for Tamil Nadu from 2001–2010 (obtained from the Department of Climate and Rainfall, Government of Tamil Nadu). The correlation coefficient between the number of bites and rainfall is 0.84, the correlation coefficient between number of deaths and rainfall is 0.87 (data not shown). <i>B</i>. Monthly snake bite incidence (blue bars) and average rainfall (red line) for Tamil Nadu in 2010. The monthly rainfall data were obtained from the Hydromet division of the Indian Meteorological Department. The correlation coefficient between the monthly snake bite distribution and the distribution of rainfall is 0.5.</p
Year-wise snakebites and death summary.
<p>From the study population, the information about the year of snakebite was obtained from the household members. The information obtained is presented accordingly for each type of study village.</p
Circumstances of snakebites and their socio-economic impacts.
<p>The circumstances of snakebite such as where and when the bite occurred, the activities of victims during bite and the place of bite on the body were obtained from the victims. In addition, the direct costs involved in the treatment of snakebites and their socio-economic impacts were also assessed. The information provided here was from 129 interviewed victims and percentages were calculated accordingly.</p
Distribution of snake bites by type of snake.
<p>Where the snake species was not identified due to the inability of people to identify the snake, or the bite occurred in dark, these are classified as ‘unknown’.</p
Distribution of snake bites by age group.
<p>The red bars show the % of the total number of people which are in each age group identified in the study population. The blue bars show the % of the population of that age group who have been bitten by snakes.</p
