Long-term health complications following snake envenoming
"The most unique health complications persisting among the majority of victims (N=46; 5.6%) were a tendency to developheadache, faintness, vertigo, and photosensitivity to sunlight, which were not present prior to the bite. This was perceived by most victims as an obstacle for engaging in their outdoor farming occupations, to the extent that some had to alternatively work in the shade, take frequent rests from work, or give up their outdoor occupations.Russell’s viper, cobra, and krait were the offending snakes in 47.8%."
"Results
Of the 816 participants who were identified as ever snakebite victims, 112 (13.7%) presented with at least one snakebite-related long-term health complication. Among them, “migraine-like-syndrome” characterized by headache vertigo, and photosensitivity to sunlight was found in 46 (5.6%); musculoskeletal disorders such as pain, local swelling, muscle weakness, deformities, contractures, and amputations were found in 26 (3.2%); visual impairment in 21 (2.6%); acute kidney injury in 4 (0.5%); skin blisters at the bite site in 5 (0.6%); psychological distress in 2 (0.2%); hemiplegia in 1 (0.1%); right-side facial nerve palsy in 1 (0.1%); paresthesia over bite site in 1 (0.1%); generalized shivering in 1 (0.1%); and chronic nonhealing ulcer in 1 (0.1%). Interestingly, 31 (3.8%) reported nonspecific somatic symptoms such as abdominal colic, chest tightness, wheezing, receding gums,excessive hair loss, and lassitude with body aches following the bite. The average duration of symptoms since snakebite was 12.7 years (SD=11.7)."
