Some behavioral and environmental factors related to Leptospirosis infection among people in Thai Binh, Ha Tinh and Can Tho provinces, 2018 - 2019

Abstract

The study was conducted to identify some behavioral and environmental risk factors for leptospirosis. A case - control study on 504 (252 cases and 252 controls), matched by age and gender, carried out at hospitals and communities in three provinces of Thai Binh, Ha Tinh and Can Tho, from October 1st, 2018 to October 31st, 2019. Behavioral factors play a protective role: bathing after farming, gardening, or contacting with animals (OR 0.25; 95%CI: 0.11 - 0.55); washing hands after using the toilet (OR 0.25; 95% CI: 0.11 - 0.55) OR 0.47; 95%CI: 0.24 - 0.95); washing hands
after farming or gardening (OR 0.26; 95%CI: 0.14 - 0.49); using gloves/boots when working in the field, garden, or contacting livestock (OR 0.53; 95%CI: 0.28 - 0.99). Factors that increase the risk of leptospirosis: drinking unboiled water (OR 2.96; 95% CI: 1.64 – 5.35); rainwater as a source of drinking water (OR 3.01); 95%CI: 1.51 - 6.01); well water as drinking water source (OR 33.76; 95%CI: 7.99 - 142.56); one-compartment/fish pond toilet (OR 16.85; 95%CI: 2.08 - 136.81); open/uncovered sewer (OR 2.39; 95%CI 1.4 - 4.05); not having garbage containers (OR 3.15; 95%CI: 1.18 – 8.42). The impact of these factors plays an important role in preventing leptospirosis.
