Interested in knowing how we collect samples? Watch this short time lapse video (30 seconds). In this video our team members are using a survey questionnaire to collect a variety of information from two participants from a Nepali indigenous community. During the interview, each participant is also collecting his own saliva samples in a plastic tube.

We filmed this video after a few hard days of work in Sarlahi district, which is in Southeast of Kathmandu. While Nepal is known for high mountains, ~50% of the Nepali population lives in the flat plains at the Himalayan foothills, known as Terai. Terai, also known as Madhes in Nepali is the breadbasket of Nepal and is home to several diverse Indo-European language communities. The oxen cart, known as bail gaada in Nepali, is a hallmark of Terai using which corn, rice, sugarcane, etc. are transported.
