Raipur, Chhattisgarh - Thirty-three-year-old Ramnath Sahu looks visibly distressed. The day before, his four-year-old son, Kuldeep, was diagnosed with sickle cell - a hereditary disease affecting the red blood cells.
"Don't worry my child, nothing will happen to you," says Kuldeep's 54-year-old grandmother, Ramvati Bai, as she caresses the boy in front of their home in the village of Akola, in Bemetara district.
Kuldeep's seven-year-old brother, Harsh, was diagnosed with the disease last year.
According to a 2013 report by the Jawahar Lal Nehru Memorial Medical College in the state's capital, Raipur, 10 percent of Chhattisgarh's population is affected by the disease, with the state's indigenous tribal population disproportionately affected.
