Kozhikode (Kerala): A six-year-old boy, who was being treated for West Nile Virus (WNV) disease here, passed away on Monday, said Kerala Health Minister K.K. Shailaja. The boy hailing from Malappuram district was under treatment for fever at the state-run Medical College Hospital in Kozhikode since earlier in March.

He was diagnosed with WNV last week, after tests conducted at the Christian Medical College hospital, that turned out to be positive. Following doubts of WNV, the Centre had dispatched a multi-disciplinary team from the National Centre for Disease Control (NCDC) to assess the spread of WNV in Kerala.
